John Cupitt 7496381fc9 more getting ready for niftisave 2018-07-13 13:08:23 +01:00
John Cupitt d186ac69d6 a more more work on niftisave 2018-07-10 17:16:49 +01:00
John Cupitt d06c2fee22 use exif_tag_get_name_in_ifd() everywhere 
exif tag names change with the ids they appear in, so you must always
use exif_tag_get_name_in_ifd(), not exif_tag_get_name()

see: https://github.com/jcupitt/libvips/pull/1030

This adds support for saving 8-Bit one band palette based PNG images
with palette based alpha channel (often called PNG8+Alpha).

The image is first converted to sRGBA and then quantized using
libimagequant controlled by the colors, Q and dither params.
