How do I generate a list of lines to draw if I have pixel data for an image, so I don't have to draw every pixel? Any language will do, although I listed what I have a working knowledge for. C is ok as well. There was a limit to how many tags I could choose. Also, you can just point me toward an algorithm. ...

What would be an appropria...

I'm trying to transition some of my IDL code to Python with...
I created a separate project and activity that downloads an image from a URL, converts it to a Bitmap, and then uses a FileOutputStream to save that file to the SD card. When in the separate project and free-standing activity, this worked fine, and I could see that the image is stored on the SD card. public class PictureDownload extends...

So I've come up with this short list of thoughts about the right way to preload images with javascript. An image preload script should be executed as soon as possible. It should be placed at the top of the HTML (in the HEAD section), un...

I have a PNG file that is 32x32 pixels. I use 8 of these as drawables in a row for my app. These drawables are not in the hdpi, mdpi, or ldpi folders. I’ve found that when starting any of the 3 standard size emulators, the screen view with all 8 drawables looks pretty much the same. I note that the ldpi emulator I’m using (QVGA) has ...
