The relevant limits are here: https://github.com/sylikc/jpegview/blob/master/src/JPEGView/MaxImageDef.h I assume the original author added these to estimate roughly how much memory would be used when an image is decompressed, but I think...

The 500 megapixel limit is to prevent integer overflow. 1024 * 1024 * 500 * 4 channels = 2097152000, slightly under the max signed 32-bit integer. To set it higher...

@sylikc I was testing PSB support using [this image](https://esahubble.org/images/heic1502a/) (69536x22230) with the limit checks commented out. I found the same issue you saw where the image is stretched and zoomed...

I think this is fixed in master

Looks like this was introduced between libjxl 0.6.1 and 0.7.0 (zoom in, you can see what look like artifacts on his suit). The same input JXL file was used. ```...
