Thank you!

And there is a lot of room for optimization on Save operation.🤔

Yep, it looks like an answer because you don't need to allocate memory for copying. Previously I observed a spike of memory usage and then decline, which is perfectly explained now, But there is another problem - operation under layers selection are not working. Steps to repro: 1. Select several layers from animated GIF (II was working with my file). 2, Try to execute any layers command over selection. (I tried delete and merge down). 3. The operation is executed only on focused layer.

Thank you! Works like a charm now. And way more memory effective based on Task Manager data.

Thank you and Happy New Year! It worked for me as well. Just wonder if it should look like that - 1518 frames and almost empty layers?

I see, mine has only 16 Gb now. Based on similar issues on StackOverflow: "The problem may be due to mixed build platforms DLLs in the project. i.e You build your project to Any CPU but have some DLLs in the project already built for x86 platform. These will cause random crashes because of different memory mapping of 32bit and 64bit architecture. If all the DLLs are built for one platform the problem can be solved."

Interesting. I wonder, how large RAM do you have on your system?

Yep. I've captured a video clip, converted it to animated GIF and then I wanted to edit it in PDN. Given @null54 experience the issue is in memory management. I agree that it's an exceptional workload for PDN.

Merry Christmas! Zip file is still larger than 256 kB, so I put it on Git - https://github.com/AlexYash/PDN-agif/blob/main/FreeCAD-0.19-delete_Cut.agif

In my case I was opening existing file and I guess that either number of layers or layers' buffer has been overflown, or just plug-in's working memory. I'm afraid that this can be clarified only by debugging this case. I can send a link to my file if needed.

I had just changed extension from .gif to .agif in File Explorer and then tried to open in PDN. It starts opening/processing the file showing process bar and in the very end it crashes firing this error. It looks like a memory leak bug. My GIF is quite large (6 Mb - video converted to GIF) and this might cause the issue.

Hi, Thank you all for the great tool and your support. I'm trying to open my GIF but got an error in the very end of file's opening process (full details in the file below). Is there any ideas how I can fix it? Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Buffer.__Memmove(Byte* dest, Byte* src, UInt64 len) at System.Buffer._Memmove(Byte* dest, Byte* src, UInt64 len) at System.Buffer.Memmove(Byte* dest, Byte* src, UInt64 len) at PaintDotNet.Surface.CopySurface(ISurface`1 source) in D:\src\pdn\src\Core\Surface.cs:line 1162 at PaintDotNet.Surface.Clone() in D:\src\pdn\src\Core\Surface.cs:line 1498 at PropertyBasedFileTypes.AgifInternal.Load(Stream input) at PaintDotNet.FileType.Load(Stream input) in D:\src\pdn\src\Data\FileType.cs:line 512 at PaintDotNet.Functional.Func.Eval[T1,TRet](Func`2 f, T1 arg1) in D:\src\pdn\src\Base\Functional\Func.cs:line 158 Details.txt
