- JPEG write should know about CMYK as well, maybe write all 4 band images as
|
|
CMYK? probably need to test Type so we don't get confused by RGBA
|
|
|
|
test CMYK JPEG write, also PNG write with new saveable
|
|
|
|
can we use convert_saveable for PPM and friends as well?
|
|
|
|
should we invert CMYK on JPEG save?
|
|
|
|
- HAVE_HYPOT could define a hypot() macro?
|
|
|
|
- write our own python extension to call a vips operation by name
|
|
|
|
result = vips_call ("name", args)
|
|
|
|
then call that from VImage_method
|
|
|
|
- do we really need VImage_method? Can't we write
|
|
|
|
__getattr__ (self, name) = lambda (obj_to_call, arguments):
|
|
|
|
or something like that?
|
|
|
|
- try
|
|
|
|
im_max ~/pics/wtc.jpg
|
|
read: done in 8s
|
|
iterate: done in 11s
|
|
255
|
|
|
|
nip2 --vips-progress -e 'max (Image_file "~/pics/wtc.jpg")'
|
|
/home/john/.nip2-7.13.2/tmp/untitled-nip2-0-XOSIR1T.v: done in 18s
|
|
iterate: done in 20s
|
|
|
|
nip2 --vips-progress ~/pics/wtc.jpg
|
|
/home/john/.nip2-7.13.2/tmp/untitled-nip2-0-X37AX1T.v: done in 23s
|
|
... then "max A1" at the cmd line
|
|
iterate: done in 32s
|
|
|
|
is there a problem
|
|
|
|
- test ppm writer
|
|
|
|
- missing libstdc++ in link? what if we configure with no openexr?
|
|
|
|
added -lstdc++ to VIPS_LIBS, but will this work on solaris etc.? maybe have
|
|
a configure option to turn off CImg
|
|
|
|
there must be an autoconf macro that finds the stdc++ library name
|
|
|
|
- test maxpos_avg, quite a few changes
|
|
|
|
WONTFIX

=======
|
|
|
|
- HAVE_HYPOT could define a hypot() macro?
|
|
|
|
- im_exr2vips can now use c++ api
|
|
|
|
- python startup fails with plugins in vipslib:
|
|
|
|
Fatal Python error: can't initialise module vips
|
|
plugin: unable to open plugin "/home/john/vips/lib/resample.plg"
|
|
plugin: /home/john/vips/lib/resample.plg: undefined symbol: im_start_one
|
|
|
|
do we need to build plugins with -rpath etc. and more libs?
|
|
|
|
or do we need to make sure our python modules export all their im_ symbols?
|
|
|
|

- can we use GraphicsMagick instead of ImageMagick?
|
|
|
|
no: current stable GraphicsMagick is missing (at least) QuantumRange and
|
|
GetNextImageAttribute() ... perhaps this will be fixed in 1.2
|

|
- TIFF load/save should use meta system for unknown tags
|
|
|
|
- balance should use new meta stuff
|
|
|
|
- magick2vips should spot ICC profiles and attach them as meta
|
|
|
|
- magick should set some header field for n_frames and frame_height? see also
|
|
analyze
|
|
|
|
- see TODO notes in openexr read (though they all need more openexr C API)
|
|
|
|
consider openexr write
|
|
|
|
- im_csv2vips() could use "-" for filename to mean stdin
|
|
|
|
but then we'd have to read to a malloced buffer of some sort rather than an
|
|
image, since we might need to grow it during the read, since we couldn't
|
|
then seek
|
|
|
|
- add erode/dilate 3x3 special case using a 512-bit LUT
|
|
|
|
... nope, actually slower :-( we end up doing an inner loop like
|
|
|
|
for( i = 0; i < 9; i++ )
|
|
bits |= (p[o[i]] != 0) << i;
|
|
|
|
which is horrible. Maybe if we had a one band true 1 bit image it'd be
|
|
quicker since we could get bits out in parallel and wouldn't have to worry
|
|
about converting non-zero to 1
|
|
|
|
could have a Coding type for bitpack? eg. relational produces a bitpack
|
|
image by default, boolean & morph can work on bitpack etc
|
|
|
|
maybe something for vips8 ... we could have a flag on operations for the
|
|
coding types they can accept, and if they are passed other type, they are
|
|
automatically converted
|
|
|
|
- non-linear sharpen: replace each pixel by the lightest or darkest neighbour
|
|
depending on which is closer in value
|
|
|
|
- can wrap other inplace funcs which use ink now we have vector_to_ink() in
|
|
inplace_dispatch.c
|
|
|
|
see also comments in nip2 TODO ... we could auto-wrap in vips_call.c
|
|
|
|
cleaner!
|
|
|
|
- on win32, should not write matrix files in binary mode, we want CR/LF chars
|
|
so we can load into excel etc easily
|
|
|
|
how odd, we're doing
|
|
|
|
if( !(fp = fopen( name, "w" )) ) {
|
|
|
|
shouldn't be binary ... hmm
|
|
|
|
Build

|
|
|
|
- xmlFree() is still broken :-(
|
|
|
|
maybe we are not importing it correctly? im_readhist.c references
|
|
|
|
_imp__xmlFree
|
|
|
|
how is this made? look at gcc -E output ... maybe there's an extra define we
|
|
need to make it generate the right link code?
|
|
|
|
see what libxml2.dll.a is exporting that looks anything like xmlFree
|
|
|
|
- can we make a fftw3.dll? also, magick.dll?
|
|
|
|
maybe just build with no-undefined? can we then link the DLL against the
|
|
static lib?
|
|
|
|
- update gtk/glib/etc. on the PC to the latest versions, apparently much
|
|
quicker (esp. pango)
|
