I am trying to resize the following GIF

Original Dimensions are: 1270 x 1270 and a total of 149 Pages

I am resizing to the following Dimensions:

  1. 250 x 250 (Successful)
  2. 500 x 500 (Successful)
  3. 750 x 750 (Unsuccessful)

It fails for the last case and after some digging I found that the limits are set in libvips. I am not able to conclude how the dimensions are violating the constraints.

Constraints Being:

if( (guint64) frame_rect.width * frame_rect.height > INT_MAX / 4 || 
        frame_rect.width > 65535 || 
        frame_rect.height > 65535 ) {
        vips_error( class->nickname, "%s", _( "frame too large" ) );
        return( -1 );
    }

Currently I have the latest govips(v2.11.0) and vips(8.13.3) versions installed.

I tried different sizes and it is working till 740 x 740. I tried to change the Export Params but am unable to figure the math behind why the frame is too large.

    Hrishikesh, please DO NOT cross post questions. Ask in one place. You are making unnecessary extra work for volunteer maintainers. – jcupitt Nov 24 '22 at 13:03
