- revisit orc conv
|
|
|
|
use an 8.8 accumulator ... build the scale into the 8.8 coeffs ... no div at
|
|
the end, just a shift
|
|
|
|
need 8 x 8.8 -> 8.8 for each coeff though
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- also VipsFormat ... could this replace vips_image_new_from_string()? or
|
|
could we call this from vips_image_new_from_string()?
|
|
|
|
at the moment, VipsFormat subclasses never get made, we just use the classes
|
|
... we'd need to start making real vipsformat objects for this to work
|
|
|
|
how would this work?
|
|
|
|
at the moment we have
|
|
|
|
image = vips_image_new_from_file( filename );
|
|
|
|
build a VipsImage with filename "r"
|
|
|
|
we also have the new CLI thing
|
|
|
|
obj = vips_object_new_from_string( class, str );
|
|
|
|
calls class->new_from_string( first-component(str) ), then sets
|
|
optional args from rest-of-str(str), then does _build()
|
|
|
|
image-class->new_from_string() just make a vipsimage "r" str
|
|
|
|
the _build() uses VipsFormat() to load via im_tiff2vips() or whatever
|
|
|
|
so ... we could change vips_image_new_from_file() to be
|
|
|
|
VIPS_IMAGE( vips_object_new_from_string( VipsImageClass, str ) )
|
|
|
|
we could also make VipsImage::new_from_string() make a real VipsFormat
|
|
object, then load options could be set from the str
|
|
|
|
how does save work? we call image-class->output_to_arg(obj, str), which in
|
|
turn calls vips_image_write(), which in turn uses VipsFormat
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- make a vips8 binding for Python as well
|
|
|
|
use ctypes and not swig so we get an easy Win version
|
|
|
|
wrap new API for C++
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- Magick:
|
|
|
|
- do we bundle "convert" in the OS X / win32 builds? if we don't we
|
|
should
|
|
|
|
- some way for nip2 to get the vips bin area
|
|
|
|
- some way for nip2 to get EXEEXT
|
|
|
|
- wrap a basic set of Magick filters
|
|
|
|
|
|
|
|
- need vips_image_invalidate_area()
|
|
|
|
|
|
|
|
|
|
- leak check, again
|
|
|
|
|
|
- add matlab write
|
|
|
|
- need a way to make the vips.1 etc. man pages
|
|
|
|
gtk has things like docs/reference/gtk/gtk-update-icon-cache.xml and man
|
|
pages are made from that with xslt
|
|
|
|
- get rid of a lot of the command-line programs, who wants to write a man page
|
|
for batch_image_convert etc yuk
|
|
|
|
- can we make man pages for the API as well? probably not from googling a bit
|
|
|
|
|
|
|
|
- use g_mmap() or whatever it's called ... or perhaps they don't have all
|
|
these options
|
|
|
|
|
|
|
|
|
|
- use |_O_TEMPORARY to open()'s mode on Windows for tmpfiles to increase the
|
|
chances we actually delete
|

- lab [100,0,0] -> srgb [255, 255, 254]? how odd
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- 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
|
|
|
|
|
|
|
|
|
|
- perspective transform with a matrix ... base it on the Lenz transformer, but
|
|
partial
|
|
|
|
|
|
|
|
|
|
|
|
- maybe im_draw_smudge() is too slow :-( also, we had a sanity failure with
|
|
it, argh
|
|
|
|
make a region, prepare to that, copy back over the image?
|
|
|
|
|
|
|
|
|
|
- use D65 in cmsCreateLab4Profile() ? not sure
|
|
|
|
- im_divide() can /0 for complex
|
|
|
|
- unlink temps earlier on *nix systems
|
|
|
|
the file is created by setupout, which is called just before generate or
|
|
writeline, so perhaps unlink on evalstart?
|
|
|
|
no, on a rewind we need to be able to close and reopen, argh

- convert_saveable for other writers: tiff, ppm, csv, rad etc.
|
|
|
|
|
|
|
|
- expose more of the tone funcs in nip2
|
|
|
|
- quite a few hist operations have no GUI ... lhisteq, for example? or
|
|
histspec?
|
|
|
|
|
|
|
|
|
|
- rename header, edvips as vipsheader, vipsedit
|
|
|
|
maybe have back compat links?
|
|
|
|
- should im_rwcheck() copy to disc?
|
|
|
|
maybe im_rwcheck_disc() copies to im->filename and maps that
|
|
|
|
rather awkward to do atm with the way check.c is structured
|
|
|
|
- what does G_UNLIKELY() do? can we use it?
|
|
|
|
- rename vipsCC in SWIG as pyvips?
|
|
|
|
- look into G_GNUC_DEPRECATED for back compat in vips8
|
|
|
|
- use
|
|
|
|
http://library.gnome.org/devel/glib/stable/glib-Byte-Order-Macros.html
|
|
|
|
for swapping ... they are asm macros so we should see a speedup
|
|
|
|
- can we use conv_sep to speed up the memuse benchmarks?
|
|
|
|
- check mosaic1, global_balance, similarity etc. use of im__affine
|
|
|
|
how can we move them to im_affinei ?
|
|
|
|
- doc strings would be nice, read the SWIG notes on this
|
|
|
|
- bilateral filtering, see:
|
|
|
|
http://en.wikipedia.org/wiki/Bilateral_filter
|
|
http://www.shellandslate.com/fastmedian.html
|
|
http://people.csail.mit.edu/sparis/bf_course/
|
|
|
|
also a mail from Martin Breidt has links to several fast free C
|
|
implementations
|
|
|
|
- try making vips_add(), an operator as a class
|
|
|
|
- need a section for vipsobject in the tutorial
|
|
|
|
also a manpage?
|
|
|
|
not really stable yet :( don't document
|
|
|
|
- how to expose things like snohalo1's "blur" parameter to
|
|
C++/Python?
|
|
|
|
can we write a find-by-nickname function? eg.
|
|
|
|
GType vips_get_type (const char *base, const char *nickname)
|
|
|
|
then
|
|
|
|
vips_get_type ("VipsInterpolator", "bicubic")
|
|
|
|
would get us the GType for VipsInterpolatorBicubic
|
|
|
|
- we shouldn't need to call im_invalidate() in gtkdisp4 :( how can we fix
|
|
this?
|
|
|
|
- we should wrap the format API, also im_render*(), see gtkdisp.cc for sample
|
|
code
|
|
|
|
- have a base VObject class and put the ref stuff in there ... share between
|
|
VMask, VDisplay, VImage
|
|
|
|
- need an im_init_world() for C++ which does cmd-line args too, so C++ progs
|
|
can get --vips-progress and stuff automatically
|
|
|
|
- more cleanups to the handling of vips format images, esp. we have vips write
|
|
spread across many files atm
|
|
|
|
- could remove a lot of crappy old API
|
|
|
|
- try
|
|
|
|
libsrc/convolution$ grep -l offsets *.c
|
|
|
|
could we do the don't calc offsets thing unless bpl; changes thing in more
|
|
places?
|
|
|
|
- unsharp should work on GREY16? should be easy to add GREY16->LABS
|
|
|
|
no, labs is signed short, ranges are all differrent, and the scaling will be
|
|
wrong anyway
|
|
|
|
correct: import with ICC to labs, then process, then export to RGB, take
|
|
green?
|
|
|
|
yuk, can we add a 16bit path to vips's lab <--> rgb converter?
|
|
|
|
use TIFF RGB16 as the 16bit RGB target
|
|
|
|
im_XYZ2disp() would be easy to 16bit ... just need the 1,500 element table
|
|
table->t_Yr2r[i] expanded
|
|
|
|
im_disp2XYZ() uses im_col_rgb2XYZ() in a loop ... again, need
|
|
the 1,500 element table table->t_r2Yr[i] expanded
|
|
|
|
usually these three tables (t_r2Yr, t_g2Yg, t_b2Yb) will be identical, can
|
|
we common them up? same for t_Yr2r etc.
|
|
|
|
how big should the table be for 16 bits? 256 times larger? too big!
|
|
|
|
we really just need a LUT for pow() with the right exponent, eg. 2.4 for
|
|
sRGBs, and one for 1/2.4 ... see what calcul_tables does:
|
|
|
|
table->t_r2Yr[i] = yo + a * pow( i * table->ristep / f + c, ga );
|
|
|
|
see
|
|
|
|
|
|
|
|
|
|
|
|
- test maxpos_avg, quite a few changes
|
|
|
|
- HAVE_HYPOT could define a hypot() macro?
|
|
|
|
- im_exr2vips can now use c++ api
|
|
|
|
see TODO notes in openexr read (though they all need more openexr C API)
|
|
|
|
consider openexr write
|
|
|
|
- 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?
|
|
|
|
check:
|
|
|
|
http://www.swig.org/Doc1.3/SWIGDocumentation.html#Python_nn8
|
|
http://docs.python.org/dist/dist.html
|
|
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?
|
|
|
|
- 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
|
|
|
|
- also png2vips?
|
|
|
|
- magick should set some header field for n_frames and frame_height? see also
|
|
analyze
|
|
|
|
- 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!
