  • HTML/JavaScript: mouseover effect for image maps?

    - by MVCDummy09
    I'm trying to help out a nonprofit by doing their website. They want (ugh) their logo to serve as an HTML image map. In other words, when you click on different parts of the logo, you're directed to different web pages. They also, however, want mouseover effects: when you mouseover a particular portion of the image map, that piece of the graphic should be highlighted. If the logo was simple, I would slice it up into rectangles and attach mouseover and click events to the appropriate rectangles. With the complexity of their logo, this is not possible, however. Has anyone done anything like this without Flash? I'm not a Flash developer but this is looking like a very difficult task in just HTML/JavaScript. Any ideas? Thanks!

  • href image link download on click

    - by Piero
    Hey all, I generate normal links like: <a href="/path/to/image"><img src="/path/to/image" /></a> in a web app. When I click on the link, it displays the picture in a new page. If you want to save the picture, then you need to right click on it and select "save as" I don't want this behaviour, I would like to have a download box popping out when I click on the link, is that possible just with html or javascript? How? If not I guess I would have to write a download.php scrit and call it into the href with the file name as parameter...? Greetings! :)

  • How to improve performance of map that loads new overlay images

    - by anthonysomerset
    I have inherited a website to maintain that uses a html map overlaying a real map to link specific countries to specific pages. previously it loaded the default map image, then with some javascript it would change the image src to an image with that particular country in a different colour on mouseover and reset the image source back to the original image on mouse out to make maintenance (adding new countries) easier i made the initial map a background image by utilising some CSS for the div tag, and then created new images for each country which only had that countries hightlight so that the images remain fairly small. this works great but theres one issue which is particularly noticeable on slower internet connections when you hover over a country if you dont have the image file in your browser cache or downloaded it wont load the image unless you hover over another country and then back onto the first country - i guess this is due to the image having to manually be downloaded on first hover. My question: is it possible to force the load of these extra images AFTER the page and all the other assets have finished loading so that this behaviour is all but eliminated? the html code for the MAP is as follows: <div class="gtmap"><img id="Image-Maps_6200909211657061" src="<?php echo cdnhttpsCheck();

  • Image 8-connectivity without excessive branching?

    - by shoosh
    I'm writing a low level image processing algorithm which needs to do alot of 8-connectivity checks for pixels. For every pixel I often need to check the pixels above it, below it and on its sides and diagonals. On the edges of the image there are special cases where there are only 5 or 3 neighbors instead of 8 neighbors for a pixels. The naive way to do it is for every access to check if the coordinates are in the right range and if not, return some default value. I'm looking for a way to avoid all these checks since they introduce a large overhead to the algorithm. Are there any tricks to avoid it altogether?

  • Image coding library

    - by Dmitry
    Is there any good library for lossless image encoding/decoding that has compression rate more or less similar to PNG but decoding to raw RGB bitmap data would be much faster than PNG? Also alpha transparency is needed, but not essential because, alpha channel could be taken from separate image. Original problem lies in slowness of reading and decoding PNG files on iPhone using standard libraries. Obvious and the simples solution would have been storing raw RGB bitmap data, but then size of unpacked ipa is too large - 4 times larger than PNG files. So, I am trying to find some compromise solution.

  • how to flip Image in wpf

    - by shashank
    Hello! I recently learned how to rotate a BitmapImage using the 'TransformedBitmap' and 'RotateTransformed' classes. Now I am able to perform clockwise rotations on my images. But how do I FLIP an image? I can't find the class(es) to perform horizontal and vertical flips of a BitmapImage. Please help me figure out how to do it. For instance, if my image was a drawing that looked like a 'd', then a vertical flip would result in something like a 'q', and a horizontal flip would result in something lika a 'b'. I hope this is clear enough. Thanks in advance! Best regards, shashank

  • Paint java GUI component to image file

    - by Simon
    Let's say I have JButton test = new JButton("Test Button"); and I want to draw the button into an image object and save it to a file. I tried this: BufferedImage b = new BufferedImage(500, 500, BufferedImage.TYPE_INT_ARGB); test.paint(b.createGraphics()); File output = new File("C:\\screenie.png"); try { ImageIO.write(b, "png", output); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } This code produced an empty 500x500 PNG-file. Does anyone know how I can draw the GUI component to an image file?

  • image upload problem.

    - by Bluemagica

Given the following HTML structure... <div id="menu"> <ul> <li><a href="#">Test</a></li> <li><a href="#">Tester</a></li> <li><a href="#">Testing Testing</a></li> </ul> </div> What is the best way to replace the text with a background image using CSS only?

  • How to Use Calculated Color Values with ColorMatrix?

    - by Otaku
    I am changing color values of each pixel in an image based on a calculation. The problem is that this takes over 5 seconds on my machine with a 1000x1333 image and I'm looking for a way to optimize it to be much faster. I think ColorMatrix may be an option, but I'm having a difficult time figure out how I would get a set of pixel RGB values, use that to calculate and then set the new pixel value. I can see how this can be done if I was just modifying (multiplying, subtracting, etc.) the original value with ColorMatrix, but now how I can use the pixels returned value to use it to calculate and new value. For example: Sub DarkenPicture() Dim clrTestFolderPath = "C:\Users\Me\Desktop\ColorTest\" Dim originalPicture = "original.jpg" Dim Luminance As Single Dim bitmapOriginal As Bitmap = Image.FromFile(clrTestFolderPath + originalPicture) Dim Clr As Color Dim newR As Byte Dim newG As Byte Dim newB As Byte For x = 0 To bitmapOriginal.Width - 1 For y = 0 To bitmapOriginal.Height - 1 Clr = bitmapOriginal.GetPixel(x, y) Luminance = ((0.21 * (Clr.R) + (0.72 * (Clr.G)) + (0.07 * (Clr.B))/ 255 newR = Clr.R * Luminance newG = Clr.G * Luminance newB = Clr.B * Luminance bitmapOriginal.SetPixel(x, y, Color.FromArgb(newR, newG, newB)) Next Next bitmapOriginal.Save(clrTestFolderPath + "colorized.jpg", ImageFormat.Jpeg) End Sub The Luminance value is the calculated one. I know I can set ColorMatrix's M00, M11, M22 to 0, 0, 0 respectively and then put a new value in M40, M41, M42, but that new value is calculated based of a value multiplication and addition of that pixel's components (((0.21 * (Clr.R) + (0.72 * (Clr.G)) + (0.07 * (Clr.B)) and the result of that - Luminance - is multiplied by the color component). Is this even possible with ColorMatrix?

  • Resizing image with Python with locked aspect ratio

    - by David Vinklar
    How should I resize an image with Python script so that it would automatically adjust the Height ratio to the Width used? I'm using the following code: def Do(Environment): # Resize App.Do( Environment, 'Resize', { 'AspectRatio': 1.33333, 'CurrentDimensionUnits': App.Constants.UnitsOfMeasure.Pixels, 'CurrentResolutionUnits': App.Constants.ResolutionUnits.PixelsPerIn, 'Height': 1440, 'MaintainAspectRatio': True, 'Resample': True, 'ResampleType': App.Constants.ResampleType.SmartSize, 'ResizeAllLayers': True, 'Resolution': 72, 'Width': 1920, }) Using this code works perfectly if the aspect ratio of an image is the same as the one defined in the code - i.e. 1.33333. But how should I make it work with images that do not have this ratio? For me, what is important is that the new Width is 1920; Height has to be able to adjust automatically. Any ideas which part of my code should be altered and how?

  • Ubuntu 12.04 - Unable to change brightness

    - by Raymond Standen
    So, as a number of users seem to be experiencing, I am unable to change brightness on my laptop. Using the Brightness and Lock in settings, the slider moves but brightness does not adjust. The fn keys work for volume but not for brightness. I have updated my drivers and installed all updates, however the brightness is still at maximum. I have heard that opening sudo gedit /etc/x11/xorg.conf and entering Option "RegistryDwords" "EnableBrightnessControl=1" can fix this, however when opening xorg.conf through Terminal I am greeted with a blank document... Not very reassuring. Toshiba L750 Laptop Nvidia Graphics Card Dual boot with Windows

  • Problem getting the background image of a form

    - by Deumber
    I'm creating a datagridview transparent //I got the parent background image Bitmap parentBackGround = new Bitmap(this.Parent.BackgroundImage); //Set the area i want to create equal to the size of my grid Rectangle rect = new Rectangle(this.Location.X, this.Location.Y, this.Width, this.Height); //And draw in the entire grid the area of the background image that is cover with my grid, making a "transparent" effect. graphics.DrawImage(parentBackGround.Clone(rect, PixelFormat.Format32bppRgb), gridBounds); When the backgroundimage of the grid's parent is show in an normal layout all work ok, but if the layout is stretch, center or any other, the transparency effent gone, have you any idea to fix it?

  • JFrame the same shape as an Image / Program running in background

    - by Jan Weber
    My question is simple, the solution surely not. I am looking for a way to shape a JFrame the same as an Image it will be displaying. By shape I mean the shape of the pixels that have an alpha != 0. I've already found a working example using a GeneralPath object, but it created ~110000 "nodes" for an Image of about 500*400, so starting the JFrame took more than 2 minutes, which is definitely not the desired effect, the startup should be in under 2 seconds. Thanks for your time.

  • Pull image of rendered HTML from a specific browser

    - by Geo Ego
    I am working on an app that will be able to pull an image of rendered HTML from a specific browser. I would like the user to be able to select a specific browser to render an HTML file in, and capture the rendered output in an image file. I am starting with IE8, and I'm not sure where to begin to get the actual rendered output. I can easily open the file in that browser with Process.Start(), but I don't know how to return the rendered output. I have looked a little bit at sinking events, but I don't understand how that works or if that's the right way to go. I would just like some direction, and perhaps some resources to send me on the right path.

  • iPhone Image Resources, ICO vs PNG, app bundle filesize

    - by Jasarien
    My application has a collection of around 1940 icons that are used throughout. They're currently in ICO and new images provided to me come in ICO format too. I have noticed that they contain a 16x16 and 32x32 representation of each icon in one file. Each file is roughly 4KB in filesize (as reported by finder, but ls reports that they vary from being ~1000 bytes to 5000 bytes) A very small number of these icons only contain the 32x32 representation, and as a result are only around 700 bytes in size. Currently I am bundling these icons with my application and they are inflating the size of the app a bit more than I would like. Altogether, the images total just about 25.5MB. Xcode must do some kind of compression because the resulting app bundle is about 12.4MB. Compressing this further into a ZIP (as it would be when submitted to the App Store), results in a final file of 5.8MB. I'm aware that the maximum limit for over the air App Store downloads has been raised to 20MB since the introduction of the iPad (I'm not sure if that extends to iPhone apps as well as iPad apps though, if not the limit would be 10MB). My worry is that new icons are going to be added (sometimes up to 10 icons per week), and will continue to inflate the app bundle over time. What is the best way to distribute these icons with my app? Things I've tried and not had much success with: Converting the icons from ICO to PNG: I tried this in the hopes that the pngcrush utility would help out with the filesize. But it appears that it doesn't make much of a difference between a normal PNG and a crushed png (I believe it just optimises the image for display on the iPhone's GPU rather than compress it's size). Also in going from ICO to PNG actually increased the size of the icon file... Zipping the images, and then uncompressing them on first run. While this did reduce the overall image sizes, I found that the effort needed to unzip them, copy them to the documents folder and ensure that duplication doesn't happen on upgrades was too much hassle to be worth the benefit. Also, on original and 3G iPhones unzipping and copying around 25MB of images takes too long and creates a bad experience... Things I've considered but not yet tried: Instead of distributing the icons within the app bundle, host them online, and download each icon on demand (it depends on the user's data as to which icons will actually be displayed and when). Issues with this is that bandwidth costs money, and image downloads will be bandwidth intensive. However, my app currently has a small userbase of around 5,500 users (of which I estimate around 1500 to be active based on Flurry stats), and I have a huge unused bandwidth allowance with my current hosting package. So I'm open to thoughts on how to solve this tricky issue.

  • Crystal Reports and WMF image

    - by Eve
    I have a problem with inserting a vector graphics (WMF) into report (Crystal Reports v10.5 from Visual Studio 2008). The image is static, inserted by choosing "Insert Picture" during report design in VS. The problem is that it displays differently (size and aspect ratio) on machines with different operating systems and screen resolutions. Converting to bitmap isn't possible beacause loss of the quality of print isn't acceptable. I thought about dynamic loading of the image, but in this version of CR. I don't see a possibility to set dynamic graphic location in picture properties. Is there any way to solve this problem?

  • Is this a "valid" css image replacement technique?

    - by user278457
    I just came up with this, it seems to work in all modern browsers, I just tested it then on (IE8/compatibility, Chrome, Safari, Moz) HTML <img id="my_image" alt="my text" src="images/small_transparent.gif" /> CSS #my_image{ background-image:url('images/my_image.png'); width:100px; height:100px;} Pro's: image alt text is best-practice for accessibility/seo no extra HTML markup, and the css is pretty minimal too gets around the css on/images off issue where "text-indent" techniques hide text from low bandwidth users The biggest disadvantage that I can think of is the css off/images on situation, because you'll only send a transparent gif. I'd like to know, who uses images without stylesheets? some kind of mobile phone or something? I'm making some sites for clients in regional Australia (hundreds of km from the nearest city), where many users will be suffering from dial-up connections, and often outdated browsers too, so the "images off" issue is an important consideration. are there any other side effects with this technique that I haven't considered?
