Re: problem with gtk+ colorselector

Hi,

 I have found a very annoying problem with gimps gtk+ colorselector.  Since 
 I don't use it normally, it came into my eye after installing digipencil. 
 
 Because the testprogramm that come with gtk+ shows the right behaviour, it 
 maybe there is a problem with the gimp inheritance of this widget.
 
 The problem:
 I click on the foreground color (black) and choose the gtk+ selector. Close 
 the color selector.
 Then click on the background (white) and the two labels under the 
 colorcircle are filled with black and white (from the left)

Very well noticed.
 
 My first problem was that I was unable to change the foreground color.  But 
 this was a problem with the value.  The circle shows a color but this color 
 has no value, so it was always black ...

The circle alone is not sufficient to choose a color. There has to be a 
way to change the colors value. But I guess you found that out pretty soon.

 And the behaviour I described above seems to be related to this.  The gtk+ 
 colorselector seems to display the color that was chosen the last time. 
 This is probably due to the fact, that the color selector isn't destroyed 
 after choosing a color.  If you leave the selector open and doubleclick on 
 the other color (back- or foreground) you can see this clearly.

The GTK+ colorselector does indeed remember the color last choosen so you
are able to see the contrast between the new color and the one you started 
with.

Now to the point: Where's the problem??


Salut, Sven

Net-Fu + Gimp 1.2.x

2001-02-02 Thread Nicolay Mausz 

Hello,

I installed Gimp 1.04 with NetFu and it works great. But I didn't manage
to work Gimp 1.2.0 with Net-Fu.

Is it possible to run Net-Fu with Gimp 1.2.x ?

incorrect mask handling in histogram calculation

2001-02-02 Thread Roel Schroeven 

I just downloaded (and installed and build) the 1.2.1. sources, and I 
was looking at the histogram code (because I wonder why the histogram 
always looks totally different than histograms from Photoshop or Paint 
Shop Pro) and I saw something (unrelated to what I was doing) that looks 
like a bug.

In gimphistogram.c there is a function to calculate the histogram for a 
subregion, declared as follows:

gimp_histogram_calculate_sub_region (GimpHistogram *histogram,
PixelRegion   *region,
PixelRegion   *mask)

In that function we have this code snippet:

  if (mask)
   {
 gdouble masked;

 src = region-data;
 msrc = region-data;

I would think that msrc ought to be a pointer into the mask data instead 
of the region data, like this:

   msrc = mask-data;

Idea: Temporary tool assignment

2001-02-02 Thread Alan 

Not sure if this has been discussed before, but after reading the article at
http://www.advogato.com/article/239.html I noticed this paragraph (on the 
subject of keyboard shortcuts):

   PhotoShop is slightly superior (for the moment) in that it has temporary
   tool assignment. You can have a paint brush tool active, and if you push
   and hold the space bar, the active tool becames the hand (for panning). The
   moment the space bar is released, the paint brush (or whatever the previous
   tool was) becomes active again. Alt while Zooming changes to Zoom Out, Ctrl
   to Zoom In. To be fair, Gimp also uses temporary tool assignment in places,
   but I picked PhotoShop as the prime example because it is more complete and
   far reaching throughout the program, at this moment in time.

This is a simple idea, that has been implemented partially (as noted, though
something like the middle button for panning works great in the gimp for me!), 
but I have seen a lot of places where it would make a lot of sense to put in 
more of these temporary tools.  The zoom is a prime example.

Any chance of this technology becoming more widespread throughout the gimp?

Please try all the tools and make a list of the ones that do nothing
with Ctrl and / or Shift and / or Alt (before clicking / after
clicking, like with Circle selection). Advice: set pointer to cross
and icon, that way it gives hints about what is happening (or will if
you click). Also keep open the Tool Options dialog, and watch the
buttons change. Tab also does magic when over an image (hit again to
get the volunteer back from backstag... err... nimbo).

I think you will be suprised, basic ops are there. Yes, there are some
things that would be nice to have in addition to current ones, but I
guess that the basics we have are plainly ignored, and thus people say
"Gimp lacks all nice functions" when the theme is "Gimp lacks some
nice functions" (and has some that PS does not have, like MB2
scrolling, I think).

BTW, the zoom / magnify thing appeared some mails ago (hold Ctrl to
swap mode, Gimp CVS 1.2). :]

Oops, late, I will read the doc after sleeping.
