Legacy ImageMagick Discussions Archive

I just tried building ImageMagick-6.2.8 but it fails due to incompatibilities w/ libpng-1.5 (structs which used to be visible are now hidden). Disabling PNG support yields some other error about atexit. If it built and worked out of the box, I'd probably have used it as a temporary stop-gap solution ...

So, the main problem is the 5 seconds for 66 frames during the save? Correct. Do you have any way to isolate that down even further? Somewhat within the save process? I have not found a way short of stepping through IM in the debugger. If not, it might be worth trying out a few different versions ...

Hmmm, yeah, only 3 colors changes things. BTW, F-S is Floyd-Steinberg, the type of dither. It's an error-correction dither, so it'll be random. Heck, for 3 colors, just turn off dither. No need for it. Ok, done (no difference in perf though). Let's talk about frames, then. What's the frame delay ...

I'm not sure if I made this clear, but I am creating the image from scratch entirely inside my app. I am not importing an image. The images I'm creating are extremely simplistic--each frame has a line and possibly a square or a circle. There are literally 3 colors in total: black, red, blue (plus ...

What's the full code of options? Here's the options I specify per frame: Image pic(g, transparentColor); pic.page(g); // set size of frame; 'g' is a Geometry object for this frame pic.density(Geometry(72, 72) ); pic.animationDelay(10); pic.gifDisposeMethod(1); pic.compressType(RLECompression); pic ...

I thought I tried setting the tree depth via quantizeTreeDepth(4) (see my original post). Is this not the proper method to use?

In my case, I am creating the frames programmatically, so I'm creating the output GIF programmatically as well (as opposed to using the pre-existing IM command-line tools).

Years ago (~2006) I created an app w/ Magick++ that created animated GIFs and it worked well. I've rebuilt it yesterday (no code change) and it runs much slower: it used to take a couple seconds, now takes over a minute. The OS is mostly the same (Gentoo Linux, so many updates since 2006, including ...
