Michael Natterer b5530e9e3d Use the new GeglAccessMode enum instead of the old values 2014-07-02 02:00:35 +02:00
Daniel Sabo 34c50b0fea app, plug-ins: Don't modify iter->length 
The new by-row iteration doesn't re-write the length
value for each row. In general it is not safe to modify
the iterator data because the internal logic depends
on the public data, but this specific case is new.

Michael Natterer 571350270b app: return 0.0..1.0 from gimp_histogram_get_mean(), median(), std_dev() 
Display the float values in the histogram dockable and add a compat
hack to the gimp_histogram() PDB wrapper.

Michael Natterer 6c97908a9e app: add "gboolean gamma_corrected" to gimp_histogram_new() 
so we can make histograms of the gamma-corrected image data. Pass
TRUE all over the place so the histogram works perceptually. This
needs more thinking...

Michael Natterer 0f0590426d app: must CLAMP() all valus to 0..1 for calculating histogram bins 
The histogram does only 0..1, there are no bins outside that range.

Michael Natterer 8d1cbd95d2 app: rename gimp_histogram_get_channel() to get_component() 
Because that's what it is. It also takes a "gint component"
(0..4) and not a "GimpHistogramChannel channel".

Michael Natterer a7f42de4c0 app: turn GimpHistorgram into a GimpObject, no other changes 2013-06-11 21:23:32 +02:00
Michael Natterer 48d312ed94 app: create > 8-bit histograms with 1024 bins 
Seems to calculate and draw correctly, just the view's range is
broken now, will fix.

Michael Natterer 96d569a50e app: make GimpHistogram use floats, and make the number of bins flexible 
It's still always 256 currently.

Massimo Valentini 0909a30b06 app: histogram typos 
correctly offset the mask,
don't crash computing the histogram of a GRAY image selection
and don't use an integer division

Michael Natterer 94da46c373 app: add precision argument to gimp_image_get_format() 
and use it instead of gimp_babl_format() in some places where indexed
formats can occur. Also fix some places using gimp_babl_format() to
special case indexed formats correctly.

Simon Budig 1f5c631970 no comma operator there... 2012-05-02 17:51:21 +02:00
Michael Natterer f624d7c16a app: calculate the histogram in 8 bit rather than creating nonsense 2012-05-02 17:51:17 +02:00
Michael Natterer 5a4cac2abd app: add XXX comment about assuming u8 to GimpHistogram 2012-05-02 17:51:09 +02:00
Michael Natterer aee6a9eb01 app: remove the legacy histogram calculation code 2012-05-02 17:51:04 +02:00
Michael Natterer 28f655ed27 app: implement the GEGL histogram with an iterator loop for now 
its body can later be reused in the working histogram sink op.
 2012-05-02 17:51:04 +02:00
Michael Natterer df5ab0f551 app: add gimp_histogram_clear_values() and use it 
instead of abusing gimp_histogram_calculate() with a NULL region for
that purpose; calculate() is about to go away.

Michael Natterer 8d5471502e app: move GimpHistogram from base/ to core/ 2012-05-02 17:46:13 +02:00
