Overview
im_ppm2vips() reads the PPM/PGM/PBM image in filename, and writes the image out in VIPS format. It can read 1, 8, 16 and 32 bit images, colour or monochrome, stored in binary or in ASCII. One bit images become 8 bit VIPS images, with 0 and 255 for 0 and 1.
im_ppm2vips_header() reads the just the header of the image into the VIPS image. You can't read any pixels!
im_vips2ppm() writes the VIPS image to the named file in PPM format. It can write 8, 16 or 32 bit integer images, colour or monochrome, stored as binary or ASCII. Images of more than 8 bits can only be stored in ASCII.
The storage format is indicated by a filename extension.
im_vips2ppm( im, "fred.ppm:ascii" )
will write to "fred.ppm" in ascii format. The default is binary.
