PPM does not support alpha transparency. Transparent JP2 areas must be flattened onto a background color.
Animated, sequence, or multipage inputs need explicit frame/page handling.
Converting JP2 to PPM decodes the source image and writes a PPM output. Use this route when PPM is a better fit for compatibility, file size, editing, or delivery.
Quality behavior depends on PPM compression: uncompressed.
Choose conversion targets based on PPM compression, transparency, animation, metadata, and compatibility requirements.
Known metadata support: color space, IP rights, XML boxes, JP2 boxes.
Supported by ImageMagick, Netpbm, and technical imaging tools.
