  • CSS Square Div with an Inward Oval Shape

    - by user2813099
    I am trying to create a div in css with an inward oval shape to it like this. At the moment, I have a shape that is outward instead of inward (JS Fiddle Link). .shape { float: left; width: 100px; height: 50px; border: none; background: #CC0000; border-radius: 0 90px 0 0; -moz-border-radius: 0 90px 0 0; -webkit-border-radius: 0 90px 0 0; background-image: -webkit-gradient( linear, left top, right bottom, color-stop(0, #520C0C), color-stop(1, #CC0000) ); background-image: -o-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%); background-image: -moz-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%); background-image: -webkit-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%); background-image: -ms-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%); background-image: linear-gradient(to right bottom, #520C0C 0%, #CC0000 100%); } Any ideas on how to go about this?

  • How to fix a slow scrolling table view

    - by hanumanDev
    I have a table view that's scrolling slowly. Does anyone know why that might be? There is an image for each row, but even after the images are loaded it still stutters and scrolls slowly. thanks for any help here's my code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *simpleTableIdentifier = @"SimpleTableCell"; SimpleTableCell *cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SimpleTableCell" owner:self options:nil]; cell = [nib objectAtIndex:0]; } // Get item from tableData NSDictionary *item = (NSDictionary *)[displayItems objectAtIndex:indexPath.row]; // display the youdeal deal image photoString = [item objectForKey:@"image"]; UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:photoString]]]; cell.titleLabel.text = [item objectForKey:@"supercat"]; cell.descriptionLabel.text = [item objectForKey:@"title"]; NSString *convertedLeftCount = [NSString stringWithFormat:@"%@",[item objectForKey:@"left_count"]]; cell.amountLabel.text = convertedLeftCount; cell.thumbnailImageView.image = image; cell.priceLabel.text = [item objectForKey:@"cat"]; return cell; }

  • google maps in jquery mobile

    - by paullb
    When showing a google map in jquery mobile it appears (after reading the forums) that code like the following is required: <div data-role="page" data-theme="b" class="page-map" style="width:100%; height:100%;"> <div data-role="header"><h1>Map Page</h1></div> <div data-role="content" style="width:100%; height:100%; padding:0;"> <div id="map_canvas" style="width:100%; height:100%;"></div> </div> </div> Taking away the height on outside div causes the div to drop to height 0 and the map not being displayed. I was hoping to get some dynamic text below the map (based on the contents on the) which length I do not know so I can't set an absolute height. Has anyone got a workaround for this problem?

  • Proper usage of Java Weak Reference in case of nested collections

    - by Tong Wang
    I need to define a weak reference Map, whose value is a Set. I use Google collections' MapMaker, like this: Map<Class<? extends Object>, Set<Foo>> map = new MapMaker().weakKeys().weakValues().makeMap(); So, for Set<Foo>, can I use a normal HashSet? Or, do I have to create a weak HashSet, like this: Collections.newSetFromMap(new WeakHashMap<Foo, Boolean>()); And why? Another question, the key of my map is Class objects, when will a Class object become weakly reachable? In other words, what is the lifetime of a Class object? Thanks.

  • Should I *always* import my file references into the database in drupal?

    - by sprugman
    I have a cck type with an image field, and a unique_id text field. The file name of the image is based on the unique_id. All of the content, including the image itself is being generated automatically via another process, and I'm parsing what that generates into nodes. Rather than creating separate fields for the id and the image, and doing an official import of the image into the files table, I'm tempted to only create the id field and create the file reference in the theme layer. I can think of pros and cons: 1) Theme Layer Approach Pros: makes the import process much less complex don't have to worry about syncing the db with the file system as things change more flexible -- I can move my images around more easily if I want Cons: maybe not as much The Drupal Way™ not as pure -- I'll wind up with more logic on the theme side. 2) Import Approach Pros: import method is required if we ever wanted to make the files private (we won't.) safer? Maybe I'll know if there's a problem with the image at import time, rather than view time. Since I'll be bulk importing, that might make a difference. if I delete a node through the admin interface, drupal might be able to delete the file for me, as well. Con: more complex import and maintenance All else being equal, simpler is always better, so I'm leaning toward #1. Are there any other issues I'm missing? (Since this is an open ended question, I guess I'll make it a community wiki, whatever that means.)

  • PHP resizing PNGs results in corrupted files

    - by Robert
    I have a PHP script that resizes .jpg, .gif, and .png files to a bounding box. $max_width = 500; $max_height = 600; $filetype = $_FILES["file"]["type"]; $source_pic = "img/" . $idnum; if($filetype == "image/jpeg") { $src = imagecreatefromjpeg($source_pic); } else if($filetype == "image/png") { $src = imagecreatefrompng($source_pic); } else if($filetype == "image/gif") { $src = imagecreatefromgif($source_pic); } list($width,$height)=getimagesize($source_pic); $x_ratio = $max_width / $width; $y_ratio = $max_height / $height; if( ($width <= $max_width) && ($height <= $max_height) ) { $tn_width = $width; $tn_height = $height; } else if (($x_ratio * $height) < $max_height) { $tn_height = ceil($x_ratio * $height); $tn_width = $max_width; } else { $tn_width = ceil($y_ratio * $width); $tn_height = $max_height; } $tmp = imagecreatetruecolor($tn_width,$tn_height); imagecopyresampled($tmp,$src,0,0,0,0,$tn_width, $tn_height,$width,$height); $destination_pic = "img/thumbs/" . $idnum . "thumb"; if($filetype == "image/jpeg") { imagejpeg($tmp,$destination_pic,80); } else if($filetype == "image/png") { imagepng($tmp,$destination_pic,80); } else if($filetype == "image/gif") { imagegif($tmp,$destination_pic,80); } imagedestroy($src); imagedestroy($tmp); The script works fine with jpeg and gif but when running on a png the file will be corrupted. Is there anything special I need to use when working with a png? I have never worked with this sort of thing in PHP so I'm not very familiar with it.

  • Can anyone help me with this VHDL code (currently malfunctioning)?

  • Should we EVER use dp values for width/height?

    - by sandalone
    I've come across a project done by some other team which I have to fix. They used dp values for images' width/height. When I tried to adopt the layout for some tablets and/or mobiles, I've faced a lot of troubles. For example, the image of 40x40 dp has top padding of 15dp. When such image is loaded by some new mobile screen, the image is not where is was supposed to be - it's either shifted or distorted or of the wrong size. Now I need to propose a redesign of the whole app and I need some advise from the more experienced community. Should I abandon such layout policy (described abobe) and do like this: make the image with the size of 40x40 px position the image for the mdpi screen set its height/width to wrap_content do like this for other images after I finish layout for mdpi, resize each image for ldpi, hdpi and xhdpi screens in case of a special mobile/tablet, make a special set of images + xml files Is there a way when you would advise to use the explicit size of some images? Do you advise setting the size of images in xml layout or setting size via photoshop or similar graphics tools and then resize images for other screen sizes or screen densities?

  • Why does document.QuerySelectorAll return a StaticNodeList rather than a real Array?

    - by Kev
    It bugs me that I can't just do document.QuerySelectorAll(...).map(...) even in Firefox 3.6, and I still can't find an answer, so I thought I'd cross-post on SO the question from this blog: http://blowery.org/2008/08/29/yay-for-queryselectorall-boo-for-staticnodelist/ Does anyone know of a technical reason why you don't get an Array? Or why an SNL doesn't inherit from an Array in such a way that you could use map, concat, etc? (BTW if it's just one function you want, you can do something like NodeList.prototype.map = Array.prototype.map;...but again, why is this functionality (intentionally?) blocked in the first place?)

  • Binding ComboBox Item with a text property of different DataContext

    - by Jhelumi786
    Hi Everyone, I have a comboBox as below. What I want is to bind the selectedItem value to a Text property of a datacontext so that another DataTemplate can show the Image. Please note that the Combobox and Target Image elements are on two different DataTemplates so that's why I need to update the Text Property (ImageName) ofDataContext at backend. <ComboBox x:Name="cboOverlay" Grid.Row="0" Grid.Column="1" SelectedIndex="0" > <ComboBoxItem Name="BC_OL" IsSelected="True"> <StackPanel Orientation="Horizontal"> <Image Source="Images\BC_OL.jpg" Width="100" Height="25" Canvas.Top="0" Canvas.Left="0" /> <TextBlock Width="100" VerticalAlignment="Center" TextAlignment="Center"><Bold>Image1</Bold></TextBlock> </StackPanel> </ComboBoxItem> <ComboBoxItem Name="Indian_OL"> <StackPanel Orientation="Horizontal"> <Image Source="Images\Indian_OL.jpg" Width="100" Height="25" Canvas.Top="0" Canvas.Left="0" /> <TextBlock Width="100" VerticalAlignment="Center" TextAlignment="Center"><Bold>Image2</Bold></TextBlock> </StackPanel> </ComboBoxItem> </ComboBox> <Image Source="{Binding Path=Image}" Width="81" Height="25" Canvas.Top="0" Canvas.Left="0" />

  • How to easily apply a function to a collection in C++

    - by Jesse Beder
    I'm storing images as arrays, templated based on the type of their elements, like Image<unsigned> or Image<float>, etc. Frequently, I need to perform operations on these images; for example, I might need to add two images, or square an image (elementwise), and so on. All of the operations are elementwise. I'd like get as close as possible to writing things like: float Add(float a, float b) { return a+b; } Image<float> result = Add(img1, img2); and even better, things like complex ComplexCombine(float a, float b) { return complex(a, b); } Image<complex> result = ComplexCombine(img1, img2); or struct FindMax { unsigned currentMax; FindMax(): currentMax(0) {} void operator(unsigned a) { if(a > currentMax) currentMax = a; } }; FindMax findMax; findMax(img); findMax.currentMax; // now contains the maximum value of 'img' Now, I obviously can't exactly do that; I've written something so that I can call: Image<float> result = Apply(img1, img2, Add); but I can't seem to figure out a generic way for it to detect the return type of the function/function object passed, so my ComplexCombine example above is out; also, I have to write a new one for each number of arguments I'd like to pass (which seems inevitable). Any thoughts on how to achieve this (with as little boilerplate code as possible)?

  • Perforce depots

    - by PeanutPower
    Is it preferred to have one depot with multiple folders which map to different paths in a workspace. OR multiple folders in one depot that map to multiple workspaces, or multiple depots to multiple workspaces. Does anyone have any practical advice on the matter? I've also noticed that when I have multiple folders in a depot that map to different paths in my workspace when i diff from the depot a change in one of the sub folders does not show up in the diff.

  • JavaScript: supposed to execute functions sequentially, not actually doing so?

    - by AP257
    I'm seeing a lot of answers on StackOverflow that say that JavaScript executes code sequentially, but I can actually see my own JavaScript not doing so. From the following code: function centre_map(lat, lng, zoom_level) { alert('centre_map'); map = new GMap2(document.getElementById('map_canvas')); var latlng = new GLatLng(lat, lng); map.setCenter(latlng, zoom_level); } function add_markers_within_bounds() { alert('add_markers_within_bounds'); // add numerous BLUE markers within map bounds using MarkerClusterer } function add_marker(lat, lng, place_name, grid, county) { alert('add_marker'); // add one ordinary RED Google Maps marker } centre_map('{{lat}}', '{{lng}}', 12); add_markers_within_bounds('{{grid}}', '{{place_name}}'); add_marker('{{lat}}', '{{lng}}', '{{place_name}}', '{{grid}}', '{{county}}'); I get the following sequence of events: 'centre_map' alert 'add_markers_within_bounds' alert 'add_marker' alert individual RED marker appears on map (i.e. add_marker renders) multiple BLUE markers appear on map (i.e. add_markers_within_bounds renders) Why doesn't add_markers_within_bounds complete before add_marker gets under way: and how can I make it do so? I know that one way might be to call add_marker from within add_markers_within_bounds, but for various reasons I'd rather keep it as a separate function.

  • Changing direction of rotation Pygame

    - by czl
    How would you change the direction of a rotating image/rect in Pygame? Applying positive and negative degree values works but it seems to only be able to rotate one direction throughout my window. Is there a way to ensure a change in direction of rotation? Perhaps change up rotation of a spinning image every 5 seconds, or if able to change the direction of the spin when hitting a X or Y axis. I've added some code below. It seems like switching movement directions is easy with rect.move_ip as long as I specify a speed and have location clause, it does what I want. Unfortunately rotation is't like that. Here I'l adding angles to make sure it spins, but no matter what I try, I'm unable to negate the rotation. def rotate_image(self): #rotate image orig_rect = self.image.get_rect() rot_image = pygame.transform.rotate(self.image, self.angle) rot_rect = orig_rect.copy() rot_rect.center = rot_image.get_rect().center rot_image = rot_image.subsurface(rot_rect).copy() return rot_image def render(self): self.screen.fill(self.bg_color) self.rect.move_ip(0,5) #Y axis movement at 5 px per frame self.angle += 5 #add 5 anglewhen the rect has not hit one of the window self.angle %= 360 if self.rect.left < 0 or self.rect.right > self.width: self.speed[0] = -self.speed[0] self.angle = -self.angle #tried to invert the angle self.angle -= 5 #trying to negate the angle rotation self.angle %= 360 self.screen.blit(self.rotate_image(),self.rect) pygame.display.flip() I would really like to know how to invert rotation of a image. You may provide your own examples.

  • GTK+ and GdkPixbuf

    - by Daniel
    Hi all, I think I've got an understanding problem of GTK. My simple application has a stream of images and I'd like to display them within my GTK Window. Up to now, it looks like this: GdkPixbuf *pb = gdk_pixbuf_new_from_data(img2, GDK_COLORSPACE_RGB, FALSE, 24/3, 320, 240, 320*3, NULL, NULL); if(pb == NULL) fprintf(stderr, "Pixbuf is null!\n"); if(image != NULL) gtk_container_remove(GTK_CONTAINER(window), image); image = gtk_image_new_from_pixbuf(pb); gtk_container_add(GTK_CONTAINER(window), image); printf("Updated!\n"); img2 is my (rgb) buffer that gets updated from a stream each time. I guess gtk_container_remove and gtk_container_add might be stupid to use for this? Here's what I've got in addition: GtkWidget *window; GtkWidget *image; gtk_init(&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_signal_connect(GTK_OBJECT(window), "destroy", GTK_SIGNAL_FUNC(destroy), NULL); /* ... */ start_routine_for_stream_that_calls_the_above(...) /* ... */ gtk_widget_show_all(window); gtk_main(); My problem is that it's not working this way... either I see only the last GdkPixbuf image or I see none, which is the correct behaviour ... But how do I manage it to show an (stream of) updated GdkPixbuf? Thanks for help

Do you know what might be causing this?

  • Bug on submitted app binary but not in the simulator - CALayer position contains NaN

    - by Jonathan Thurft
    I submitted my app to the App Store where is ready to download. I've since then received some interesting crash reports when people select an image from the ImagePicker in one of my views. This bug (see below) makes the app crash. I was wondering 2 things. Can anyone spot the problem in the code below? How do you deal with bugs that are only in the App Binary but do not show up when trying to recreate them on the dev environment? - I can make the app crash with the Binary that is on the app store but when I do the same on the simulator or on my test phone the app works perfectly.. The Crash report in BugSense CALayer position contains NaN: [798 nan] Class: CALayerInvalidGeometry 0x00120e99 -[imageCroppingViewController imagePickerController:didFinishPickingMediaWithInfo:] (imageCroppingViewController.m:126) + 163481 The Code - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; imageView.image = image; CGRect rect; rect.size.width = image.size.width; rect.size.height = image.size.height; imageView.center = scrollView.center; [imageView setFrame:rect]; scrollView.contentSize = imageView.frame.size; self.navigationController.navigationBar.hidden = NO; [myPicker.view removeFromSuperview]; }

  • Iterate over defined elements of a JS array

    - by sibidiba
    I'm using a JS array to Map IDs to actual elements, i.e. a key-value store. I would like to iterate over all elements. I tried several methods, but all have its caveats: for (var item in map) {...} Does iterates over all properties of the array, therefore it will include also functions and extensions to Array.prototype. For example someone dropping in the Prototype library in the future will brake existing code. var length = map.lenth; for (var i = 0; i < length; i++) { var item = map[i]; ... } does work but just like $.each(map, function(index, item) {...}); They iterate over the whole range of indexes 0..max(id) which has horrible drawbacks: var x = []; x[1]=1; x[10]=10; $.each(x, function(i,v) {console.log(i+": "+v);}); 0: undefined 1: 1 2: undefined 3: undefined 4: undefined 5: undefined 6: undefined 7: undefined 8: undefined 9: undefined 10: 10 Of course my IDs wont resemble a continuous sequence either. Moreover there can be huge gaps between them so skipping undefined in the latter case is unacceptable for performance reasons. How is it possible to safely iterate over only the defined elements of an array (in a way that works in all browsers and IE)?

    Hi Folks, I want to pass the String value between the classes both are same package. so i created the the classs like the code: public class Map_Delegate { String myLatitude; String myLongitude; String myName; private String TAG = "Map_Delegate"; public String getMyName() { return this.myName; } public void setMyName(String value) { Log.v(TAG, value); this.myName = value; } public String getMyLatitude() { return this.myLatitude; } public void setMyLatitude(String value) { Log.v(TAG, value); this.myLatitude = value; } public String getMyLongitude() { return this.myLongitude; } public void setMyLongitude(String value) { Log.v(TAG, value); this.myLongitude = value; } } But it can't pass the value. I done like this code to set the value: Map_Delegate map = new Map_Delegate(); map.setMyName(first_name_temp + " " + last_name_temp); map.setMyLatitude(homeLatitude_temp); map.setMyLongitude(homeLongitude_temp); code to get the value: Map_Delegate map = new Map_Delegate(); name_val = getMyName(); lat_val = getMyLatitude(); long_val = getMyLongitude(); Why get the Null value can you Guess?

  • Howto display or view encrypted data in encrypted form?

    - by Brian Gianforcaro
    In the Wikipedia Article on Block Cipher Modes they have a neat little diagram of an unencrypted image, the same image encrypted using ECB mode and another version of the same image encrypted using another method. At university I have developed my own implementation of DES (you can find it here) and we must demo our implementation in a presentation. I would like to display a similar example as shown above using our implementation. However most image files have header blocks associated with them, which when encrypting the file with our implementation, also get encrypted. So when you go to open them in an image viewer, they are assumed to be corrupted and can't be viewed. I was wondering if anybody new of a simple header-less image format which we could use to display these? Or if anyone had any idea's as to how the original creator of the images above achieved the above result? Any help would be appreciated, Thanks Note: I realise rolling your own cryptography library is stupid, and DES is considered broken, and ECB mode is very flawed for any useful cryptography, this was purely an academic exercise for school. So please, no lectures, I know the drill.

Please advise? public override void ViewDidLoad () { base.ViewDidLoad (); this.mapContainer.AutosizesSubviews = true ; this.View.AutosizesSubviews = true ; try { this.mapContainer.AutoresizingMask = UIViewAutoresizing.FlexibleHeight | UIViewAutoresizing.FlexibleWidth ; this.map.AutoresizingMask = UIViewAutoresizing.FlexibleHeight | UIViewAutoresizing.FlexibleWidth ; this.map.SizeToFit(); this.mapContainer.SizeToFit(); this.map.SizeToFit(); this.View.Frame = new System.Drawing.RectangleF(0,0,this.View.Frame.Width, this.View.Frame.Height ); this.mapContainer.LayoutSubviews(); } catch(Exception ex) { Console.Write(ex.ToString()); } }

  • Why did this new line just show up on my google maps

    - by ooo
    i am using the google maps API (v3). I just realized that a new line showed up at the bottom of my map that says: Map Data 2010 AND, AfriGIS (Pty) Ltd, Europa Technologies, Inva, Geosysternas SRL, Maplink . . . . How do i get rid of this? Its longer than my map so it gets truncated and looks weird, is there any way to fix this (if there is no way to do #1)
