- work though headers making sure old im_ stuff is gone
- add MATLAB write
- need a way to make the vips.1 etc. man pages
@ -49,46 +52,6 @@
- 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
