[Gimp-user] Re: Placement of pasted selections
Greetings. In article [EMAIL PROTECTED], David Herman wrote: Say I have two images of the same size (9952×7016) open. I select an arbitrary region from the first image and Edit-Copy it. Then I switch to the second image and Edit-Paste. Unfortunately, GIMP seems to put the selection wherever it wants; I would rather it appear in the exact same place as in the original image. Since the images are so big, it's difficult for me to drag the selection with the mouse to the exact spot it should appear. Is there some way I can modify GIMP's default selection placement behaviour? Use one of your selection tools to select the desired portion of your image go to the menu, Script-Fu - Selection - To Brush follow the directions in the dialog (give the brush a name and a file name) and spacing info if needed. Press ok and wait while your brushes are updated. Then you can use your selection as a brush wherever you desire. This saves some time and memory, but then you still have the problem of having to manually place the brush (i.e., copied selection) in the new image at the right place. The images I'm working with are too large for me to do this accurately. It occurs to me, however, that if one assumes that the selection is rectangular, then there must be a way to use a script-fu program to do this copy/paste automatically. It would need only implement the following algorithm, which assumes there are two images open and a selection is active in the active window: 1. Store the top left coordinates (x,y) of the selection. 2. Copy the selection. 3. Switch to the second image. 4. Paste. 5. Move the selection to (x,y). 6. Anchor the selection. The only trouble is, since I don't know Scheme and don't know the script-fu Gimp API, writing this six-line program will probably take me a few hours of research. I will eventually end up doing this unless someone here can come up with a better solution, or perhaps generously offer to write the script for me. :) Regards, Tristan -- _ _V.-o Tristan Miller [en,(fr,de,ia)]Space is limited / |`-' -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=In a haiku, so it's hard (7_\\http://www.nothingisreal.com/ To finish what you ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

On a system without much RAM this can cause a lot of swapping and possibly even thrashing. I see you had not actually tried it. :-) The GIMP can handle this quite efficiently. First, neither the GIMP nor any program I know actually make a memory copy of an object that was copied to the clipboard - the clipboard is just given a reference to the object. And when pasting, as far as the tiles are not changed, the same data in memory is shared by both images. So, all you have to do is paste the new layer, close the original image, and then crop the pasted layer. The memory in use will not exceed the memory needed to keep both images open at the same time. You can also work a python-fu /script-fu script to do a paste located stuff - the way I can think of you will have toi manually type in the destination coordinates, but I think it will suit your needs for know. Let me know if you'd need such a script, and tell me if you have gimp-python running - as I'd prefere doing it in Python than in script-fu.

Re: [Gimp-user] Re: Placement of pasted selections
If images are equal size and coordinates are the same, you can do this manually, I think. Just remember coordinates from selection. Select area in first image, copy it, make selection of the same size and location in second one and then paste. And you can make separate layer from that pasted part for fine tuneing. I'd do so if I were you :) On Thu, 29 Dec 2005 12:43:25 +0200, Tristan Miller [EMAIL PROTECTED] wrote: It occurs to me, however, that if one assumes that the selection is rectangular, then there must be a way to use a script-fu program to do this copy/paste automatically.

Re: [Gimp-user] Re: Placement of pasted selections
There is also a Perl interface for GIMPv2 at http://search.cpan.org/~sjburges/Gimp-2.2pre1/Gimp.pm but I have not coded anything to use it so can't offer any insight to its use.
