Cleanup gettext handling (#2695) 
Use GLib's i18n support instead of copying and pasting that
logic into its own header. This deprecates the vips/intl.h
header in favour of glib/gi18n.h.

John Cupitt 63d54e5df2 final code cleanups after stream -> source rename 2019-12-30 14:23:51 +00:00
John Cupitt 4c5873809f experiment with renaming stream 
rename as VipsConnection, VipsSource, VipsTarget etc.

see https://github.com/libvips/libvips/issues/1494#issuecomment-569498619

John Cupitt 1e2ca2e0bf fix refleak in webpsave_buffer 
And add teardown to the test-suite so we can spot refleaks more easily.

docs: replace `gif-loop` with `loop` 2019-12-17 16:28:04 +01:00
John Cupitt 562da3e5ab rename new_from_filename as new_from_file 
So VipsStreami matches VipsImage. Same for new_to_filename.
 2019-11-22 17:13:20 +00:00
John Cupitt f5a4f41edf rename VipsStream* variables 
The convention is now:

	VipStreami *streami;

We had `input` in many places, a left-over from the old VipStreamInput
name.
 2019-11-11 09:09:34 +00:00
John Cupitt 53f73881f7 rename streamo constructors 
Was vips_streamo_new_from_filename(), renamed as
vips_streamo_new_to_filename(). Same for descriptor and memory.

John Cupitt 50468a07a2 clean up foreign 
various cosmetic changes:

- pngsave_buffer now uses Write, not WriteBuf, same change for
  radsave_buffer

- move C wrappers out to class defs from foreign.c

- use g_free() not vips_free() for buffer free from low-level savers

- fix var names in some comments

- various style changes for radiance.c

Felix Bünemann 3b7242f743 Fix webpsave alpha_q default value 2016-05-09 13:08:11 +02:00
Felix Bünemann 0a25f6efca Add alpha_q(uality) webpsave option, fix Q init 
This allows to control the fidelity of the alpha channel by allowing
webp to reduce the number of palette entries from 256 at alpha_q=100
to 2 at alpha_q=0. This is most useful with cutout pictures where
something like alpha_q=30 or around 8 levels is usually sufficient
for smooth outlines.

For some reason webp->Q was intiailized to 80 even though the Q option
and libwebp use 75 by default. This was never used, so it's just to
avoid confusion about what default is used.
 2016-04-24 18:18:40 +02:00
Felix Bünemann c107066c4e Add webpsave near_lossless support, fix Q range 
The near_lossless option allows to enable preprocessing for the lossless
mode. This is a boolean instead of an int, because the amount of
preprocessing is controlled using the Q factor parameter which is
otherwise unused in lossless mode. This allows to re-use the quality
setting in existing tools.
 2016-04-23 02:00:32 +02:00
Felix Bünemann 58a2616f77 New webpsave option smart_subsample 
This enables a high quality RGB to YUV converter in libwebp which
greatly improves the quality of fine details by reducing color bleeding
caused by the 4:2:0 chroma subsampling. This is slower and causes
slightly larger files. See WebPPictureSmartARGBToYUVA in libwebp.
 2016-04-23 01:20:41 +02:00
Felix Bünemann f834ea39f6 Add lossy compression "preset" option to webpsave 
This allows to tune the lossy webp encoder for certain types of images.

John Cupitt 01025328da fix some cppcheck warnings
