Hi guys,

I'm a big fan of Gimp.

Couple of questions:

1. I have installed Gimp 2.8.16 also on Windows 8.1 x64. Strangely, in Task Manager Gimp never shows over 2 GB RAM memory (I have 4 GB) (like a 32 bit app). However, once I had over a thousand layers summing 10 GB, Task Manager showed still 2 GB for Gimp. I know Gimp compresses the layers, but still... Is there an explanation for this...?
Btw, Gimp is installed in "Program files" folder, not "Program files (x86)".

2. I have a plugin for exporting layers to png files and it's performing well. However sometimes it's preferable to save the result of a plugin directly to png instead of layer. For example the mathmap plugin who saves the frames as layers. Is there any way to save the frames directly as (png) files?

3. For some functions from the mathmap plugin a 4 digit precision may be not enough, especially when you generate many frames with very little difference between them. For example in user values I can input only 6.283 as 2 * PI. Is there any way to increase the precision?

4. For generating the frames with the mathmap plugin I use as input a svg file. If I choose the input resolution = the output resolution 768x768 and apply the transformations, it doesn't look that good. I already checked AntiAliasing and Supersampling. I'm thinking of trying to double/triple/quadruple the input resolution, apply all the changes and downsize to 768x768.
Is it gonna look better?
Even if it is, I will have to generate the frames in groups, because I don't have RAM for all of them. But, it's a pain to do it this way, because of the (only) 4 digit precision...

Any advice?

Thank you.

Sorry in advance if I posted in the wrong section.

1) Edit>Preferences>Environment>Tile cache size and set to whatever RAM you'll want Gimp to use.

2) Uh?

3) Gimp channels values are coded on 8-bit (which in decimal is roughly 2.5 digits). Future versions (starting with th experimental 2.9 which is available) also allow for 16-bit or 32-bit. But the plugins you use may not be compatible with them (and even so, they may bot take advantage of the higher precision)

Thank you.

Let me show you what I'm trying to do.

Using Gimp and a few plugins I generated these png frames: link1 from attachment
I used APNG Assembler x64 version (link2 from attachment) to make an apng: link3 from attachment
I recompressed the png files as jpeg with 80/95/100% quality and assembled them as animated jpegs using this tool: link4 from attachment

The result was these files: links 5..8 from attachment

You can use that tool to view/play them.

Btw, that tool was not made for general use, so the interface and the code are not 100% "user friendly" and/or will not do 100% what you expect to do. It's just a test application before making the real one.
