Description [src]

Read a GIF file into a libvips image.

Use page to select a page to render, numbering from zero.

Use n to select the number of pages to render. The default is 1. Pages are rendered in a vertical column. Set to -1 to mean “until the end of the document”. Use vips_grid() to change page layout.

Use fail_on to set the type of error that will cause load to fail. By default, loaders are permissive, that is, VipsFailOn.

The output image is RGBA for GIFs containing transparent elements, RGB otherwise.
