branch for new dev cycle - argh, missing init from colour.c (thanks Peter) - argh, im_measure() was not looping over bands correctly (thanks Peter) - removed mmap_limit, we now always use windows ... reduces VM use hugely, because mmap windows are freed when their regions are freed, while images are only unmapped when they are closed -

revised more names, limited documented API - im_buildlut() could segv for non-zero based tables (thanks Jack) - VIPS_BUF_STATIC() does not take length arg - check for SetImageOption() so we work with GraphicsMagick too - "header" sets a non-zero exit code if anything failed - add and use im_check_uncoded() and friends - matlab load handles column-major and plane-separated images (thanks Mikhail) - JPEG save allows "none" for profile, meaning don't attach a profile - saner, simpler, faster typecasting for im_add(), im_subtract(), im_multiply(), im_divide(), im_remainder() - im_remainder() has a float result for float types - im_measure() allows sel == NULL, meaning all patches - added "deprecated" package - faster, simpler, better im_max(), im_min, im_avg(), im_deviate() - im_max() returns true modulus, not square of modulus, for complex images - im_avg() works for complex, returning average modulus - im_system() fix (thanks Roland) - im_system() rewrite - im_maxpos()/im_minpos() are partial and work for complex - im_max()/im_min() are now convenience functions - im_maxpos_avg() handles complex and multi-band images - added im_point(), rewrite im_point_bilinear() in terms of this - close callbacks now happen *after* images have closed resources (such as open files) ... this lets them delete temps and stuff. Expect breakage :( - added vips_interpolate_get_window_offset() - boolean revised: smaller, more general, faster - im_remainderconst_vec() renamed to im_remainder_vec() for consistency - added im_shift*_vec() -

im_jpeg2vips.c, set scale_num on shrink (thanks Guido) - heh argh reading history always stopped after the first line (thanks Haida) - added im_histindexed - new im_iterate() calls start and stop functions from workers so resources they make are owned by the worker thread ... this makes it possible to have start functions which create multiple regions and therefore allows im_iterate() to scan more than one image at once -
