• UIImagePickerController and extracting EXIF data from existing photos

  - by tomtaylor

  It's well known that UIImagePickerController doesn't return the metadata of the photo after selection. However, a couple of apps in the app store (Mobile Fotos, PixelPipe) seem to be able to read the original files and the EXIF data stored within them, enabling the app to extract the geodata from the selected photo. They seem to do this by reading the original file from the /private/var/mobile/Media/DCIM/100APPLE/ folder and running it through an EXIF library. However, I can't work out a way of matching a photo returned from the UIImagePickerController to a file on disk. I've explored file sizes, but the original file is a JPEG, whilst the returned image is a raw UIImage, making it impossible to know the file size of the image that was selected. I'm considering making a table of hashes and matching against the first x pixels of each image. This seems a bit over the top though, and probably quite slow. Any suggestions?

• Google Charts Through CURL

  - by swt83

  I have a PHP class that helps me generate URLs for custom charts using Google Chart service. These URLs work fine when I load them in my browser, but I'm trying to pull them using CURL so I can access the charts on secure https websites. Whenever I try and pull a chart via CURL, I get an Error 400 Bad Request. Any idea on how to get around this? Everything I have tried has failed. $url = urldecode($_GET['url']); $session = curl_init($url); // Open the Curl session curl_setopt($session, CURLOPT_HEADER, false); // Don't return HTTP headers curl_setopt($session, CURLOPT_RETURNTRANSFER, true); // Do return the contents of the call $image = curl_exec($session); // Make the call #header("Content-Type: image/png"); // Set the content type appropriately curl_close($session); // And close the session die($image);

• UIScrollView and UIImage in it with paging enabled

  - by Infinity

  Hello guys! I need to display 10 - 1000 images on a UIScrollView. Paging is enabled. So every page of the scrollview is an image, it is an uiimage. I can load 10 images to 10 uiimages which stays in the memory, but with 1000 images I have problems on the iPhone or on the iPad. I am trying to unload and then load the images when I am doing scrolling. I every time displays 3 images. The current page image, and the -1 and +1 pages. When I am scrolling I unload the image and then load the next. With this method I have two problems. The scrolling is laggy and if I scroll very fast the images don't appear. Maybe is there any good solution for these problems? Can you suggest me one?

• Having problems building Cairo on x64 CentOS

  - by Vnuk

  I've done this many times on 32 bit CentOS and everything went ok without a hitch. But now, on x64 CentOS, I can't get cairo to find pixman. Pixman 0.18.0 is installed in /usr/local/lib (which I believe is the usual location). Configure for Cairo 1.8.10 can't find it: checking for cairo's image surface backend feature... checking for pixman... no no checking whether cairo's image surface backend feature could be enabled... no (requires pixman-1 >= 0.12.0 http://cairographics.org/releases/) configure: error: mandatory image surface backend feature could not be enabled I've tried setting environment variable pixman_LIBS=/usr/local/lib but wihtout any luck. Any idea what is going wrong? Is it possible for me to see where is cairo's configure looking for pixman? Search paths or something like that?

• Linux Live USB Media

  <b>Jamie's Random Musings:</b> "It is pretty common these days for laptops, and even desktops, to be able to boot from a USB flash memory drive. So you can save a little time and a little money by converting various Linux distributions ISO images to bootable USB devices, rather than burning them to CD/DVD."

• PHP - Foreach in a foreach + CodeIgniter

  - by Sebhael

  I got an image upload function working, but there's 4 images required in this image. And my current function is simply just overwriting the image despite the number. I'm wondering how I would insert (preferably) a letter into my foreach function. $uploads = array($this->uploads->data()); foreach ( $uploads as $key[] => $value ) { $imagename = $cleaned . '-s' . $value['file_ext']; //outputs clean-name-s.ext } By the time all is said and done, 4 images will require this function. Leaving me with clean-name-sa.ext, clean-name-sb.ext, clean-name-sc.ext, and clean-name-sd.ext (numbers work as well). The form does require that all 4 fields are filled out before submission, so would I just create an array of my desired identifiers and create a foreach loop that outputs 4 different $imagenames? Or is there a simpler, more logical approach to this.

• Determining your websites color scheme

  - by Steve Hayes

  One of the biggest issues I have, from a UI standpoint, when building a new website is figuring out what colors I will use and of those colors, do they actually work well together. I found this site that has really helped me out and I figured I would share it with all of you and also get some responses back about either sites similar or other ways that you get/figure out your color schemes. Here is the site that I currently use: http://kuler.adobe.com/ With Adobe Kuler, you can chose a base color and it will suggest 5 colors, including your color, that go well with one another. You can, of course, modify the colors it chooses. Also,one of the main features I use, is the image color matching. You can upload an image and it will determine a color scheme based on the colors of the image. So if you have a logo and want to use the colors of the logo, then this works perfectly for you. Thank you and I look forward to your feedback!

• LaTeX: Default font(s) for greek letters?

  - by Marco

  I'm a programmer but new to (La)TeX. As far as I can tell, neither the Computer Modern nor Latin Modern fonts have glyphs for the full greek alphabet. I installed (OS X) a Latin Modern font that came with TeX Live (lmroman10-regular.otf). As you can see in the attached image, the lowercase greek letters (and nabla) are displayed (TextEdit) using some default font. Also shown in the image is LaTeXiT displaying pretty lowercase greek letters that seem to be Latin-Modern-Italic-ish. So what font(s) are used by LaTeX for greek (and math symbols)? Where would I find them in the TeX fonts directory? Image: http://imgur.com/dvyyB.png

• API Message Localization

  - by Jesse Taber

  In my post, “Keep Localizable Strings Close To Your Users” I talked about the internationalization and localization difficulties that can arise when you sprinkle static localizable strings throughout the different logical layers of an application. The main point of that post is that you should have your localizable strings reside as close to the user-facing modules of your application as possible. For example, if you’re developing an ASP .NET web forms application all of the localizable strings should be kept in .resx files that are associated with the .aspx views of the application. In this post I want to talk about how this same concept can be applied when designing and developing APIs. An API Facilitates Machine-to-Machine Interaction You can typically think about a web, desktop, or mobile application as a collection “views” or “screens” through which users interact with the underlying logic and data. The application can be designed based on the assumption that there will be a human being on the other end of the screen working the controls. You are designing a machine-to-person interaction and the application should be built in a way that facilitates the user’s clear understanding of what is going on. Dates should be be formatted in a way that the user will be familiar with, messages should be presented in the user’s preferred language, etc. When building an API, however, there are no screens and you can’t make assumptions about who or what is on the other end of each call. An API is, by definition, a machine-to-machine interaction. A machine-to-machine interaction should be built in a way that facilitates a clear and unambiguous understanding of what is going on. Dates and numbers should be formatted in predictable and standard ways (e.g. ISO 8601 dates) and messages should be presented in machine-parseable formats. For example, consider an API for a time tracking system that exposes a resource for creating a new time entry. The JSON for creating a new time entry for a user might look like: 1: { 2: "userId": 4532, 3: "startDateUtc": "2012-10-22T14:01:54.98432Z", 4: "endDateUtc": "2012-10-22T11:34:45.29321Z" 5: }   Note how the parameters for start and end date are both expressed as ISO 8601 compliant dates in UTC. Using a date format like this in our API leaves little room for ambiguity. It’s also important to note that using ISO 8601 dates is a much, much saner thing than the \/Date(<milliseconds since epoch>)\/ nonsense that is sometimes used in JSON serialization. Probably the most important thing to note about the JSON snippet above is the fact that the end date comes before the start date! The API should recognize that and disallow the time entry from being created, returning an error to the caller. You might inclined to send a response that looks something like this: 1: { 2: "errors": [ {"message" : "The end date must come after the start date"}] 3: }   While this may seem like an appropriate thing to do there are a few problems with this approach: What if there is a user somewhere on the other end of the API call that doesn’t speak English?  What if the message provided here won’t fit properly within the UI of the application that made the API call? What if the verbiage of the message isn’t consistent with the rest of the application that made the API call? What if there is no user directly on the other end of the API call (e.g. this is a batch job uploading time entries once per night unattended)? The API knows nothing about the context from which the call was made. There are steps you could take to given the API some context (e.g.allow the caller to send along a language code indicating the language that the end user speaks), but that will only get you so far. As the designer of the API you could make some assumptions about how the API will be called, but if we start making assumptions we could very easily make the wrong assumptions. In this situation it’s best to make no assumptions and simply design the API in such a way that the caller has the responsibility to convey error messages in a manner that is appropriate for the context in which the error was raised. You would work around some of these problems by allowing callers to add metadata to each request describing the context from which the call is being made (e.g. accepting a ‘locale’ parameter denoting the desired language), but that will add needless clutter and complexity. It’s better to keep the API simple and push those context-specific concerns down to the caller whenever possible. For our very simple time entry example, this can be done by simply changing our error message response to look like this: 1: { 2: "errors": [ {"code": 100}] 3: }   By changing our error error from exposing a string to a numeric code that is easily parseable by another application, we’ve placed all of the responsibility for conveying the actual meaning of the error message on the caller. It’s best to have the caller be responsible for conveying this meaning because the caller understands the context much better than the API does. Now the caller can see error code 100, know that it means that the end date submitted falls before the start date and take appropriate action. Now all of the problems listed out above are non-issues because the caller can simply translate the error code of ‘100’ into the proper action and message for the current context. The numeric code representation of the error is a much better way to facilitate the machine-to-machine interaction that the API is meant to facilitate. An API Does Have Human Users While APIs should be built for machine-to-machine interaction, people still need to wire these interactions together. As a programmer building a client application that will consume the time entry API I would find it frustrating to have to go dig through the API documentation every time I encounter a new error code (assuming the documentation exists and is accurate). The numeric error code approach hurts the discoverability of the API and makes it painful to integrate with. We can help ease this pain by merging our two approaches: 1: { 2: "errors": [ {"code": 100, "message" : "The end date must come after the start date"}] 3: }   Now we have an easily parseable numeric error code for the machine-to-machine interaction that the API is meant to facilitate and a human-readable message for programmers working with the API. The human-readable message here is not intended to be viewed by end-users of the API and as such is not really a “localizable string” in my opinion. We could opt to expose a locale parameter for all API methods and store translations for all error messages, but that’s a lot of extra effort and overhead that doesn’t add a lot real value to the API. I might be a bit of an “ugly American”, but I think it’s probably fine to have the API return English messages when the target for those messages is a programmer. When resources are limited (which they always are), I’d argue that you’re better off hard-coding these messages in English and putting more effort into building more useful features, improving security, tweaking performance, etc.

• ubuntu-12.04-wubi-i386.tar.xz for the wubi installer

  - by Alejandro

  I ran the wubi installer (from an extracted ubuntu ISO) and it downloads ubuntu-12.04-wubi-i386.tar.xz but it's slow and non-resumable so I cancelled it, found a mirror of the file online and downloaded it using Intenet download manager. Where should I be placing ubuntu-12.04-wubi-i386.tar.xz file so the wubi installer won't have to download that file anymore? Thank you. Update: I extracted the archive and there are two files, I'm afraid I do not know where to place them.

  In my app, a user can select an image, change the picture of a UIImageView to the new imge, and save the image to NSUserDefaults using NSKeyedArchiver. When the user selects the image the app immediately crashes! Here is my code - - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { [picker dismissModalViewControllerAnimated:YES]; if ([[NSUserDefaults standardUserDefaults] integerForKey:@"PictureKey"] == 1) { UIImage *previmage = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; [prevbutton setImage:previmage]; NSData *previmagedata = [NSKeyedArchiver archivedDataWithRootObject:previmage]; [[NSUserDefaults standardUserDefaults] setObject:previmagedata forKey:@"PrevImage"]; } else if ([[NSUserDefaults standardUserDefaults] integerForKey:@"PictureKey"] == 2) { UIImage *nextimage = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; [nextbutton setImage:nextimage]; NSData *nextimagedata = [NSKeyedArchiver archivedDataWithRootObject:nextimage]; [[NSUserDefaults standardUserDefaults] setObject:nextimagedata forKey:@"NextImage"]; }else { UIImage *optionsimage = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; [moreoptionsbutton setImage:optionsimage]; NSData *optimagedata = [NSKeyedArchiver archivedDataWithRootObject:optionsimage]; [[NSUserDefaults standardUserDefaults] setObject:optimagedata forKey:@"OptionsImage"]; } } Thanks in advance!

• Silverlight with using of DependencyProperty and ControlTemplate

  - by Taras

  Hello everyone, I'm starting to study Silverlight 3 and Visual Studio 2008. I've been trying to create Windows sidebar gadget with button controls that look like circles (I have couple of "roundish" png images). The behavior, I want, is the following: when the mouse hovers over the image it gets larger a bit. When we click on it, then it goes down and up. When we leave the button's image it becomes normal sized again. Cause I'm going to have couple of such controls I decided to implement custom control: like a button but with image and no content text. My problem is that I'm not able to set my custom properties in my template and style. What am I doing wrong? My teamplate control with three additional properties: namespace SilverlightGadgetDocked { public class ActionButton : Button { /// <summary> /// Gets or sets the image source of the button. /// </summary> public String ImageSource { get { return (String)GetValue(ImageSourceProperty); } set { SetValue(ImageSourceProperty, value); } } /// <summary> /// Gets or sets the ratio that is applied to the button's size /// when the mouse control is over the control. /// </summary> public Double ActiveRatio { get { return (Double)GetValue(ActiveRatioProperty); } set { SetValue(ActiveRatioProperty, value); } } /// <summary> /// Gets or sets the offset - the amount of pixels the button /// is shifted when the the mouse control is over the control. /// </summary> public Double ActiveOffset { get { return (Double)GetValue(ActiveOffsetProperty); } set { SetValue(ActiveOffsetProperty, value); } } public static readonly DependencyProperty ImageSourceProperty = DependencyProperty.Register("ImageSource", typeof(String), typeof(ActionButton), new PropertyMetadata(String.Empty)); public static readonly DependencyProperty ActiveRatioProperty = DependencyProperty.Register("ActiveRatio", typeof(Double), typeof(ActionButton), new PropertyMetadata(1.0)); public static readonly DependencyProperty ActiveOffsetProperty = DependencyProperty.Register("ActiveOffset", typeof(Double), typeof(ActionButton), new PropertyMetadata(0)); public ActionButton() { this.DefaultStyleKey = typeof(ActionButton); } } } And XAML with styles: <UserControl x:Class="SilverlightGadgetDocked.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:SilverlightGadgetDocked="clr-namespace:SilverlightGadgetDocked" Width="130" Height="150" SizeChanged="UserControl_SizeChanged" MouseEnter="UserControl_MouseEnter" MouseLeave="UserControl_MouseLeave"> <Canvas> <Canvas.Resources> <Style x:Name="ActionButtonStyle" TargetType="SilverlightGadgetDocked:ActionButton"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="SilverlightGadgetDocked:ActionButton"> <Grid> <Image Source="{TemplateBinding ImageSource}" Width="{TemplateBinding Width}" Height="{TemplateBinding Height}"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style x:Key="DockedActionButtonStyle" TargetType="SilverlightGadgetDocked:ActionButton" BasedOn="{StaticResource ActionButtonStyle}"> <Setter Property="Canvas.ZIndex" Value="2"/> <Setter Property="Canvas.Top" Value="10"/> <Setter Property="Width" Value="30"/> <Setter Property="Height" Value="30"/> <Setter Property="ActiveRatio" Value="1.15"/> <Setter Property="ActiveOffset" Value="5"/> </Style> <Style x:Key="InfoActionButtonStyle" TargetType="SilverlightGadgetDocked:ActionButton" BasedOn="{StaticResource DockedActionButtonStyle}"> <Setter Property="ImageSource" Value="images/action_button_info.png"/> </Style> <Style x:Key="ReadActionButtonStyle" TargetType="SilverlightGadgetDocked:ActionButton" BasedOn="{StaticResource DockedActionButtonStyle}"> <Setter Property="ImageSource" Value="images/action_button_read.png"/> </Style> <Style x:Key="WriteActionButtonStyle" TargetType="SilverlightGadgetDocked:ActionButton" BasedOn="{StaticResource DockedActionButtonStyle}"> <Setter Property="ImageSource" Value="images/action_button_write.png"/> </Style> </Canvas.Resources> <StackPanel> <Image Source="images/background_docked.png" Stretch="None"/> <TextBlock Foreground="White" MaxWidth="130" HorizontalAlignment="Right" VerticalAlignment="Top" Padding="0,0,5,0" Text="Name" FontSize="13"/> </StackPanel> <SilverlightGadgetDocked:ActionButton Canvas.Left="15" Style="{StaticResource InfoActionButtonStyle}" MouseLeftButtonDown="imgActionInfo_MouseLeftButtonDown"/> <SilverlightGadgetDocked:ActionButton Canvas.Left="45" Style="{StaticResource ReadActionButtonStyle}" MouseLeftButtonDown="imgActionRead_MouseLeftButtonDown"/> <SilverlightGadgetDocked:ActionButton Canvas.Left="75" Style="{StaticResource WriteAtionButtonStyle}" MouseLeftButtonDown="imgActionWrite_MouseLeftButtonDown"/> </Canvas> </UserControl> And Visual Studio reports that "Invalid attribute value ActiveRatio for property Property" in line 27 <Setter Property="ActiveRatio" Value="1.15"/> VERY BIG THANKS!!!

• CoreGraphics on iPhone. What is the proper way to load a PNG file with pre-multiplied alpha?

  - by dugla

  For my iPhone 3D apps I am currently using CoreGraphics to load png files that have pre-multiplied alpha. Here are the essentials: // load a 4-channel rgba png file with pre-multiplied alpha. CGContextRef context = CGBitmapContextCreate(data, width, height, 8, num_channels * width, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); // Draw the image into the context CGRect rect = CGRectMake(0, 0, width, height); CGContextDrawImage(context, rect, image); CGContextRelease(context); I then go on and use the data as a texture in OpenGL. My question: By specifying pre-multiplied alpha - kCGImageAlphaPremultipliedLast - am I - inadvertently - telling CoreGraphics to multiply the r g b channels by alpha or - what I have assumed - am I merely indicating that the format of the incoming image has pre-multiplied alpha? Thanks, Doug

• OpenCL or OpenGL – which one to use?

  - by Malte Schledjewski

  My Problem involves a black and white image with a black area in the middle. I never worked with OpenGL or OpenCL before so I do not know which one to chose. I want to put some white circles over the area and check at the end whether the whole image is white. I will try many combinations so I want to use the GPU because of its parallelism. Should I use OpenGL and create the circle as a texture and put it on top of the image or should I write some OpenCL kernels which work on the pixel/entries in the matrix?

• Trying to resize an NSImage which turns into NSData

  - by Ricky

  I have an NSImage which I am trying to resize like so; NSImage *capturePreviewFill = [[NSImage alloc] initWithData:previewData]; NSSize newSize; newSize.height = 160; newSize.width = 120; [capturePreviewFill setScalesWhenResized:YES]; [capturePreviewFill setSize:newSize]; NSData *resizedPreviewData = [capturePreviewFill TIFFRepresentation]; resizedCaptureImageBitmapRep = [[NSBitmapImageRep alloc] initWithData:resizedPreviewData]; [saveData writeToFile:@"/Users/ricky/Desktop/Photo.jpg" atomically:YES]; My first issue is that my image gets squashed when I try to resize it and don't conform to the aspect ratio. I read that using -setScalesWhenResized would resolve this problem but it didn't. My second issue is that when I try to write the image to a file, the image isn't actually resized at all. Thanks in advance, Ricky.

• How to modify Toolbar Icon to show Text in FCKEditor

  - by justinl

  Does anyone know how I can add text into the toolbar? I would like to add some text to one of the buttons just like how the button for "Source" has the small icon, but also has the word "Source" beside it to describe what that button does. Basically none of my test users knows that the little mountain icon is used insert an image. Because of this, I would like to either replace that icon with the words "upload image" or I'd like to keep that little mountain icon, and have the words "upload image" beside it, to help people understand that's the icon for images.

• iPhone: Changing CGImageAlphaInfo of CGImage

  - by TechZen

  I have a PNG image that has an unsupported bitmap graphics context pixel format. Whenever I attempt to resize the image, CGBitmapContextCreate() chokes on the unsupported format (Error formatted for easy reading): CGBitmapContextCreate: unsupported parameter combination: 8 integer bits/component; 32 bits/pixel; 3-component colorspace; kCGImageAlphaLast; 1344 bytes/row. The list of supported pixel formats definitely does not support this combination. It appears I need to redraw the image and move the alpha channel information to kCGImageAlphaPremultipliedFirst or kCGImageAlphaPremultipliedLast. I have no idea how to go about doing this. There is nothing unusual about the PNG file and it isn't corrupted. It works in all other context just fine. I encountered this error just by chance but obviously my users might have similarly formatted files so I will have to check my app's imported images and correct for this problem.

• Loading Images with Real Screen Resolution (Flash AS3)

  - by yar

  I am loading JPEGs into a Flash presentation using load with a flash.display.Loader and it's working great. The JPEGs are sizing to their native resolution (which is perfect). However, if I maximize the Flash presentation (in the Flash Player), the JPGs do NOT take advantage of the bigger screen. For example, the presentation is 1024x768, and the image is 1280x400. Normally the image shows with a part offscreen in the Flash presentation. However, if I expand the Flash presentation to 1680x1200, the freshly loaded image still goes offscreen. Is there any way to load the jpg (or png, or whatever) to take advantage of the displayed resolution of the Flash presentation? Edit: I realize this question is hard to read, so any help would be appreciated.

• Load nsimage from url but only some url's work

  - by happyCoding25

  I have some code that loads an image file off the web and puts it in an image view. The problem is it works with everything but Google Charts. This is frustrating because I was relying on this to graph data for my app. Heres the url I need to load: Click to see my test chart. Im not sure why NSImage seems to refuse to load this when it works with everything elese. If you know why or have a work-around any help is appreciated. Heres some sample code I found that I'm using to load the images: NSURL *imageURL = [NSURL URLWithString:@"http://chart.apis.google.com/chart?cht=p3&chs=700x400&chd=t:20,20,20,20,20&chl=A|B|C|D|E&chco=66FF33,3333CC"]; NSLog(@"url"); NSData *imageData = [imageURL resourceDataUsingCache:NO]; NSLog(@"data"); NSImage *imageFromBundle = [[NSImage alloc] initWithData:imageData]; (Note: This code will load any image except a chart) Thanks

• Disabling Button with custom Content in Silverlight?

  - by andrej351

  Hi there, What is the easiest way to create a Silverlight Button with custom Content which knows how to 'look' disabled? I.e. if you set IsEnabled="False" it will look greyed out. The custom Content will be dead simple, text and an image. I have done this before in a WPF application quite easily by setting the Content to a StackPanel containing a TextBlock and an Image. I then implemented a Style Trigger on the Image to change it to a greyed out version when it wasn't enabled. The text changed colour by itself. As far as I can tell the custom Content disappears altogether when the button is disabled in Silverlight. Any help is appreciated. Cheers, Andrej.
