Hi

I'd like to use a gradient as an alpha channel , so that for instance an image fades to transparent. 
I made a white->black radial gradient and did 'color->color to alpha' but now am stumped as to how to make this into the alpha channel for another image - I dont seem to be able to paste it as an alpha channel from 'Channels' which seemed like the most logical thing to do , and if I add this as a layer to another image and then merge down I lose the gradient alpha.
Maybe I need to use a mask?

and won't let me resize the printing larger (it will let me go smaller)

I imported a PDF into gimp, choosing the option to import each page as a layer. 

I manually typed a PPI of 600. The previous imports into gimp using the automatic PPI of 100 were low res and blurry - much less clear than Acrobat Reader showed them. This new import appeared to retain sharpness that the 100PPI dropped.

I expanded the canvas and distributed the layers (pages) of the PDF, so now I have an image 8.5 inches across the top and (number of pages times 11.5 inches) down.

When I try to print this, gimp tries to print the whole thing on one 8.5 by 11 inch sheet. I got similar results with a 2 page or a 12 page import.

I cannot increase the print size on the print dialog (image properties tab)- the maximum it'll go is 100.9mm by 250mm. I can type in a larger size but when the caret leaves the field it immediately snaps back down. Gimp does let me reduce the size.

under image-> print size dialog it lets me change print size but when I actually go to print the size has returned to the maximum of 100x250mm on the image properties tab and again I can only decrease the size, not increase it. 


I'm using version 2.8.22.

Hello
I am using GIMP and INKSCAPE to do cloth personalisation and up-cycling, on LINUX 16.04 Xubuntu.
I have a picture of a stitch garment in 2 colours. (see attachement for a picture with reduced definition)
I would like to get a path from this picture in order to use it in INKSCAPE.
I have tried to use colour selection then selection to path; But the path contains some 35000 nodes and when open in INKSCAPE it never comes back.

I have a high picture definition. I thought about reducing the definition but I am afraid to get "staircases" instead of curves. Do you have any suggestion on howx I could reduce the number of nodes. Is there a modificcation of the image before doing the selection which could help. The "contiguous coulor "selection does not work any better. So any help would be welcomed.

I am trying to install GIMP Git version on a Fedora GNOME 64bit edition.

When I do './autogen.sh' in the gimp folder I get informed about missing dependencies:

Hello, using GAP is there a way to accomplish this?  Id like to insert a layer into every frame of video using GAP and have the new layer appear in the same location in each frame. I can do it manually one frame at a time which is time-consuming (and beside that, when doing it manually I cannot figure out a way to get the new layer to appear in the same exact location  on each frame autmomatically) I have to drag the new layer into place on each frame and i can never get it to the exact same spot.

thanks!

   

• Removed the Gimp-2.6-specific code
  
• Fixed the positioning of characters (no more residual jitter)
  
• Added "Repeated" layout option
  
• Added "Reverse path direction" option
  
• Added "Boxes" option
  
• Fixed handling of closed strokes
  
• Improved performance (paths not added to image unless necessary)
  
• Repackaged/renamed "ofn-"
  

Hi all,
I've very recently started using GIMP for some pic editing and I've been trying to delete selections of pictures, but when I try to delete the selected part, it just turns grey. 
I've gone through and added an alpha channel, used the lasso tool to select the part I want to delete and managed to get the marching ants around it, but when I try to clear or cut it, grey.
Any help would be really appreciated! 

Thanks

Hi:

I posted this on the Linux Mint forum. I received no suggested solutions, but others have experienced the same behavior with Gimp. One suggested looking for a Gimp forum and, having found this, I thought I would ask again here...

ORIGINAL POST ON MINT FORUM:
I'm using Mint 18.2-Cinnamon-64 bit with the stock 2.8 Gimp as installed (I haven't added the usual stuff to it, since this is a new install).

After using it for a few days, it has become apparent that the Recently Used File List periodically becomes empty. I had experienced this issue before on Ubuntu 16.04 (but I don't recall running into it in earlier versions of Ubuntu or even on Windoze). Since that Ubuntu 16.04 install was more than a year old, I just assumed that I had installed something else along the way that caused the problem and I learned to live with it but, on a new install (totally new; new OS on a new drive, only stock apps, etc.) I have to assume it's something more fundamental - either to Gimp or something in Ubuntu that is inherited by Mint/Cinnamon.

For instance, I last used Gimp with several files on Friday afternoon (it's now Saturday morning), and the list is empty. Yesterday afternoon when I loaded a file, the list had about ten items.

So I checked ~/.local/share/recently-used.xbel: it had no Gimp listings in the file. Then I loaded Gimp, opened a file, saved it, and exited.

Now, once again ~/.local/share/recently-used.xbel has an entry for the file I just opened. I reopened Gimp and the Recently Used File List contains just that one file name.

Gimp seems to be able to write to and read from the xbel so I'm guessing something external is emptying it. I can't correlate the file list clearing with anything else I've been doing. Does anyone have any suggestions?

Thanks.

Does anyone know what the brush setting of 'Force' do in Gimp 2.9?

The Gimp docs say 'TO DO,' I guess that means someone still needs to describe it.

The best I can tell is that force means how opaque the transparent pixels will draw, somewhere between the brush and pencil tool, but I don't really know.

Hello,

I'm trying to embed a icm profile sRGB IEC61966-2.1 into a layered PSD made of PNG images problematically using using python pdb call's in gimpfu v2.6.9.
it seems to always default to sRGB and does not embed the IEC version any idea how to do this
using exiftool and imagemagic convert on a psd results in gimp not being able to read it.

profile="/path/.../sRGB_Color_Space_Profile.icm"
image = pdb.gimp_image_new(width, height, RGB)
...
pdb.gimp_layer_set_name(layer, name)
pdb.gimp_image_add_layer(image, layer, 0)
...
pdb.plug_in_icc_profile_apply(image, profile, 0, False)
pdb.plug_in_icc_profile_set( image, profile)
pdb.file_psd_save(image, layer, output, output, 0, 0)

Cheers
Richard
