Working with selections and channels.
Hi all, I've been exploring the more advanced aspects of Gimp (well more advanced than Paintbrush anyhow). I think I've got the right end of the stick when it comes to channels as a method of storing selections for later use. However I've across a problem/feature I can't think of a way to work around. 1). Take a picture, select an area (such a sports car) and convert this to a channel - great works fine. 2). Deselect area (as if you're doing something else) and use channels to restore selection, cut and paste - I now have the selection as a floating selection. 3). Move/Rotate/Scale the selection to a different area of picture, I want to save this new selection/position to another channel so I can do work with it later - but I can't seem to do it. Whilst the selection is floating the 'convert to channel' is greyed out, and as soon as I defloat to current or new layer I lose my selection. Anyone have any workarounds?? Simon Wood PS.

Problem building 'po' in 1.1.25
Hi all,
I've got a problem building gimp-1.1.25. 'Configure' seems to run through OK but
it fails in the 'po' (and 'po-libgimp' if I skip 'po').
I have successively built 1.1.22 in the past, but it appears to skip the make
in 'po'.
I've started with 1.1.22 source and patched it up to 1.1.25.
Offensive bit in po/Makefile is:
GMSGFMT = PATH=../src:$$PATH no
MSGFMT = no
.po.gmo:
file=$(srcdir)/`echo $* | sed 's,.*/,,'`.gmo \
&& rm -f $$file && $(GMSGFMT) -o $$file $<
After typing 'make':
Making all in po
make[2]: Entering directory `/usr/src/packages/gimp-1.1.25/po'
file=./`echo ca | sed 's,.*/,,'`.gmo \
&& rm -f $file && PATH=../src:$PATH no -o $file ca.po
/bin/sh: no: command not found
make[2]: *** [ca.gmo] Error 127
make[2]: Leaving directory `/usr/src/packages/gimp-1.1.25/po'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/src/packages/gimp-1.1.25'
make: *** [all-recursive-am] Error 2
It's possible that I need to install something else on the system but don't
really know where to start.
Thanks in advance for any help,
Simon Wood.
RE: The "Bucket Fill" Tool in GIMP for Windows
Hi Andrew, Can you not use layers I mean. 1). Select the areas you wish to fill (select tool, magic wand, etc) 2). Create a new layer, keeping the previous selection 3). Use bucket fill on new layer. 4). Play around (OK carefully adjust ;-) ) mode and opacity 5). Merge layers when happy. Simon Wood
RE: creating animated gifs -> making MPEG movies
I've no experience with 'convert' and it's 'mpg' features, but I have successfully used the 'mpeg2encode' to animate small movies. I've put an example of some stuff I did a while ago at http://www.mungewell.uklinux.net/spotlite.mpg (508KBytes) the individual frames were made with Povray, but could be any source Hope this helps Simon Wood
Writing and de-bugging Script-Fu.
Hi all, A while ago I wrote a little script to convert the 'continuous' output from my Fujifilm DX-10 (1024x768 image which is a 3x3 matrix of smaller shots taken about 1/5 second apart) to a layered GIF animation. However I now find that with the latest GIMP for Windows (gimp-setup-2201.zip - based on 1.1.15) it no longer works. Does nothing at all, doesn't even generate the second image :-( Is there a method for single stepping a script (so you can follow it's progress) or outputting a text string (i.e print "stage 1 complete") to the screen? Failing that can anyone see what is wrong? http://www.mungewell.ndirect.co.uk/fujidx10/fuji-anim.scm Simon Wood
RE: New User: How do you achieve the following?
Dear Jon, and colleges (if that's the right word for members of list...) Thanks you for your suggestions, I'll have a play later tonight. Though I have to read up about 'Guides' and 'Alpha to Selection'. As well as Jon's suggestion, Ian Boreham pointed out that Greyscale is totally un-saturated, and therefore Hue does not affect it. So I can do this: 1). Cut and paste greyscale. 2). Adjust curves on 'patch' and remove blue & green content (change to black/red). This makes it fully saturated. 3). Adjust Hue with 'Image-Colours-Hue/Saturation'. 4). Merge Layers down when happy. It doesn't give the ability to set an arbitrary Hue, but I'm sure I can get what I want by trial and error with the +/- bit. (I guess I can measure the Hue later with the 'Color Picker'). Thanks to all for the help, Simon Wood
New User: How do you achieve the following?
Hi all, I'm new to Gimp, yes I have read the manualbut I'm having difficulty getting my head around the following problem. I would like to create a RGB image, as a layered collage of monochrome patches (cut out from other images) each of which will have a different hue (i.e. one patch is black/green, another is black/mild-pink, etc.). Q). What is the best way to change the hue of a patch of 'grey-scale' to a specific setting? I can select 'image-color-hue/saturation', but this doesn't seem to work with a 'grey-scale' patch in a RGB image. The only way I've found if to use two layers for each 'patch', the top with the grey-scale image set to 'multiply', and another of sold colour (of the desired hue) with the same bounds (shape) as the top. The main problems with this are: * it requires twice as many layers to compose the image. * it is difficult to keep track of the bounds of each patch (when scaling etc.). * the 'layer-pairs' interact with each other until their elements are merged together. Thanks in advance for any help or suggestions, Simon Wood
