when toggling the visibility of a single layer image with
alpha channel, zoomed at 50%, the projection wasn't
properly redrawn. It seems there's a GEGL bug exposed
by normal layer mode operation fast path.
measure the time it takes to render projection chunks and continue
rendering until 0.01 seconds have passed. This ways we avoid excessive
expose roundtrips.
so we can control how much time it takes, and can further optimize it.
This is needed for gtk3 because it should happen between clock ticks,
not in the expose handler, and in gtk2 the old code would have the
unfortunate property to potentially render at very high frame rates,
including all the overhead of exposing.
In gimpgrouplayer.c always gimp_pickable_flush() after
gimp_projectable_structure_changed() so all queued updates are
actually flushed to the projection buffer's invalid area, and are
constructed upon reading. This would have been neccessary before for
group layers, but worked anyway until we changed
gimp_projection_get_buffer() to construct the buffer on idle time
initially in order to make images appear more responsively after
loading.
It's about importing in fact.
Parse BITMAPV4HEADER / BITMAPV5HEADER and use GIMP's BMP
implementation instead of using gdk_pixbuf.
Also, remove an old hack about 32bits bmp v3 + alpha. The alpha
channel is already ignored in that case.
which removes a rectangle from the handler's dirty region, for cases
where the caller knows that the rectangle has been explicitly
constructed. Only needed by the gtk3-port branch.
and separate the chunk rendering logic from the fact that it's invoked
from an idle callback. Idle rendering no longer works in GTK+ 3.8 and
later because the expose logic was changed from an idle function to a
frame clock, and when we switch to that in gtk3-port, the diff to
master should stay readable (and rebasable) in this critical part of
the code.
Improvements:
- setenv/getenv() are not thread-safe, hence they should be run only at
startup before any threading occurs.
- it is counter-productive to load the huge ISO-639 XML file each time
the user opens the Preferences dialog or the text tool options.
The main change is that even with only 1 image in single window mode,
there is now a tab.
Also whatever the number of images when you hide docks with Tab, no tabs
are shown.
- Takes 2048 samples instead of 256 to handle properly large palettes.
It gives also better results with gradients.
- linearly interpolate values between two samples when
mapping with a gradient, to handle properly float precision.
Some languages have no 2-letter ISO-639-1. This is the case in particular
for 3 languages we have translations for: ast (Asturian), csb (Kashubian)
and nds (Low German), which have only 3-letter ISO-639-2/3 codes.
They were not visible in the list of languages in the Preferences dialog
until now.
setenv() does not behave well on some systems, in particular OSX (and
probably some BSDs), when the set value is NULL. In this case, let's
unsetenv() the environment variable instead.
