I'm converting some Actionscript code from AS2 tp AS3, and I've eventually managed to get most of it to work again (it's allmost a totally different language, sharing just a little syntax similarity). One of the last things that still doesn't work, is the code for loading an external image. Perhaps this has changed in AS3 but I really t...
I'm using grails j2d which in turns uses GraphicsBuilder to make a simple service to scale an image. My problem is specifically accessing the downloaded image height and width attributes in order to pass the correct parameters to the scale method. How do I access these attributes inside the transformations closure? Controller{ def sca...
Is there a way of automatically generating a HTML-Map compatible list of coordinates of polygon-like objects (e.g. countries on a map) with very distinctive borders? Example image: Final output: <map id ="ceemap" name="ceemap"> <area shape="poly" coords="149,303,162,301,162,298,171,293,180,299,169,309,159,306,148,306,149,303" hr...
Hello I will have around 200,000 images as part of my website. Each image will be stored 3 times: full size, thumbnail, larger thumbnail. Full size images are around 50Kb to 500Kb. Normal tech: Linux, Apache, MySQL, PHP on a VPS. What is the optimum way to store these for fast retrieval and display via a browser?? Should I store ever...
I need to display 2d images in opengl using textures. The image dimensions are not necessarily powers of 2. I thought of creating a larger texture and restricting the display to the part I was using but the image data will be shared with openCV so I don't want to copy data a pixel at a time into a larger texture. EDIT - it turns out tha...

I have a very large background image (about 940x940 pixels) and I'm wondering if anyone has tips for compressing a file this large further than Photoshop can handle? The best compression without serious loss of quality from Photoshop is PNG 8 (250 KB); does anyone know of a way to compress an image down further than this (maybe compress...

I have an application that I want to export high-resolution (or rather, high pixel density?) images for printing - for example, I want images that print at 250 dots per inch (DPI), instead of the default, which I understand to be 72 DPI. I'm using a BufferedImage with a Graphics2D object to draw the image, then ImageIO.write() to save t...
I know there are many ways to prevent image caching (such as via META tags), as well as a few nice tricks to ensure that the current version of an image is shown with every page load (such as image.jpg?x=timestamp), but is there any way to actually clear or replace an image in the browsers cache so that neither of the methods above are n...
I'm adding some functionality to my site so that users can upload their own profile pictures, so I was wondering about whether to store them in the database as a BLOB, or put them in the file system. I found a question similar to this here: Storing images in DB: Yea or Nay, but the answers given were geared more towards people expecting...

Hello all, One of the nice feature of the Image control is that we can specified an Uri as the ImageSource and the image is automatically downloaded for us. This is great! However, the control doesn't seem to have a property indicating if the image loading is in progress or not. Is there a property telling us the status (Downloading, D...

A couple of years ago, we had a graphic designer revamp our website. His results looked great, but he unfortunately introduced a new unsupported font by the web browser. At first I was like, "What!?!"... since most of our content is dynamic and there was no real way to pre-make all of the images. There was also the issue of multiple la...

Ideally multiple projects in multiple solutions will use the same...
