描述

If I try to resize an image to a big value like 5000 (both for width and height) my program will load for some time and then it will just exit with no errors seen in console.

Expected Behavior

It should resize the image correctly and I should get a image that is 5000x5000

Current Behavior

Doesn't work and the program just exists.

研究方向
Investigate why resizing a GIF to large dimensions (e.g., 5000x5000) causes the Jimp program to exit silently without an error. This may be due to memory exhaustion or a bug in the GIF plugin's resize handling. Look into Jimp's source code for the resize method and the GIF plugin (jimp gif). Check for similar issues or commits related to large GIF resizing. Reproduce with a sample GIF and test with smaller sizes to narrow down the threshold. Consider adding error handling or logging to identify the failure point.
