- attach the jpeg thumbnail and multiscan fields (thanks Mike)
- faster tiff read for some common cases
- faster im_tile_cache()
- add -lstdc++ to vips-7.xx.pc, if we used it
- if we use C++ in libvips, add -lstdc++ to vips-7.xx.pc
- im_vips2png() / im_png2vips() set / get png resolution (thanks Zhiyu Wu)
- updated README
- don't use tables for bilinear on float data for a small speedup (thanks

- bilinear timings
- lab [100,0,0] -> srgb [255, 255, 254]? how odd
- try writing docs for vipsthumbnail with gtkdoc? then try header etc.
how does gtk do the docs for it's various command-line progs? should be easy
to find with grep
we need to have a separate docs package for the tools/ dir
- move im_shrink & friends to resample?
match_linear, match_linear_search?
what about im_stretch3.c, im_resize_linear
- im_conv()/im_morph() could have more than 10 programs? try 20 and see if we
still have a speedup
make a base class for vector area operations with a matrix with three vfuncs
for init / generate code for one element / end and a gslist of programs, use
that as the base for morph and conv
wait for vipsobject for this
- why is im_setupout() necessary for WIO output? couldn't writeline call it if
it's not been called?
equally, could pincheck/poutcheck/outcheck be made optional?
im_region_create() could call pincheck for you, for example
though would this cause problems with threading? we need to incheck
from the main thread, not from a worker during pipeline build
open_lazy does a pincheck to rewind the disc conversion, but that could be
removed
incheck is necessary to make ->data valid I suppose, though perhaps
IM_IMAGE_ADDR() could call it for you
- perhaps replace all these with a single call:
int im_setup( IMAGE *im, VipsStyle style );
typedef enum VipsStyle {
VIPS_STYLE_PARTIAL,
VIPS_STYLE_WHOLE
};
and set read or write with:
int im_inputs( IMAGE *im, ... )
int im_output( IMAGE *im, ... )
this is all done for us by the new vips8 API though, don't bother changing
this now
- perspective transform with a matrix ... base it on the Lenz transformer, but
partial

no, on a rewind we need to be able to close and reopen, argh
