Can anyone please confirm that yes/no Gnuplot 4.5 (on CVS) can output 2D animated PNG files? I have numerous datasets but one line that I'd like to show iteratively in 3 different places in my graph.

I'm using a PHP script that I found a while back that lets you specify text in a GET variable and it will convert it to a transparent PNG. This allows me to use non web safe fonts in my websites without having to manually convert each piece of text to an image. I've run into a slight problem, though, as seen here: http://imagebin.ca/vie...
I am having an issue with an embedded 64bit Python instance not liking PIL. Before i start exhausting more methods to get a compiled image editor to read the pixels for me (such as ImageMagick) i am hoping perhaps anyone here can think of a purely Python solution that will be comparable in speeds to the compiled counterparts.

Hi all I am a first time poster. I have a problem that seems very common to a lot of people but I can't seem to find or decipher an answer anywhere. The game I'm making has 3 rather large sprites on screen (230 high) x various widths. Each sprite has 3 1024x1024 character sheets where the frames of animations are taken from. I've ex...

Hi, I'm doing an animate with JQuery UI. I've go an icon which I want to stick out over the edge of the div, so I'm using negative margins. The animation resizes the div and changes the background color. However, when I animate the div the areas of the image outside the div (in the neg margins) disapear for the duration of the animat...

Hi there, Is it better to have a PNG, say 320px x 44px and display it once, or to have a PNG that is 320px x 4px and use [UIColor colorWithPatternImage:]? I know that the iPhone handles PNGs well and decompresses them, so in terms of memory, would it be best to use the smallest possible images, and in this case, use the UIColor method ...

However when I come to save the master image it only appears to be just the empty master image with transparent background and none of the sprites. ...
Lately I've been interested in representing uncompressed bitmaps in memory. However, one thing I'm not sure how to implement properly is binary transparency. E.g., I start out with something like this: struct RGBPixel { uint8_t red; uint8_t green; uint8_t blue; }; struct bitmap { struct RGBPixel *data; size_t width; size_t height...
