  How to take a blue and black line out of the image
Posted by: chagguk - 01-13-2019, 03:44 PM - Forum: General questions - Replies (2)

Hi, I know this is a noobie question but I'm new here, and I don't know where I clicked, but this red and blue line appeared in the middle of my drawing. Anyone knows how to disable that, please?

  gimp-image-insert-layer: Item 'Background' (2) has already been added to an image
Posted by: Skippy - 01-12-2019, 11:08 PM - Forum: Scripting questions - Replies (4)


I am trying to write a script which would insert an image as a layer within layers of another image.  Here is what I got so far :

(define (foobar filename)
  (let* (
; open image to add
     (inputfile (car (gimp-file-load RUN-NONINTERACTIVE filename filename)))
     (picture (car (gimp-image-get-active-layer inputfile)))
; open file to insert image into
     (template (car (gimp-file-load RUN-NONINTERACTIVE "template.xcf" "template.xcf")))
; add picture to template
    (gimp-image-insert-layer template picture 0 -1)
; flatten image
    (gimp-image-flatten template)
; couldn't get this line to work outside the next one, probably have to investigate "let" syntax
;    (drawable (car (gimp-image-get-active-drawable template)))
    (file-jpeg-save RUN-NONINTERACTIVE template (car (gimp-image-get-active-drawable template)) "outfile.jpg" "outfile.jpg" 0.95 0.95 1 1 "" 2 1 0 2)

I call the script with gimp -i -b '(foobar "picture.jpg")' -b '(gimp-quit 0)'.

However it fails on gimp-image-insert-layer :

Quote:GIMP-Error: Calling error for procedure 'gimp-image-insert-layer':
Item 'Background' (2) has already been added to an image

batch command experienced an execution error:
Error: ( : 1) Procedure execution of gimp-image-insert-layer failed on invalid input arguments: Item 'Background' (2) has already been added to an image

I am struggling to understand this, the only results I get are two old threads on GF.c from which the useful replies have been removed…

What's wrong with my script ?

New baby. Its purpose is to make it easy to coalesce many layers into a single image (for instance, to simultaneously edit the colors of all frames in an animation) or to split a single layer into many tiles (for instance to restore the animation).

As a side effect, it can also be used to arrange layers of identical size in a gird.

ofn-layer-tiles is here.

As usual, the ZIP contains an HTML doc.

  G'MIC for 2.10.8
Posted by: PointyHairedBoss - 01-12-2019, 09:01 PM - Forum: Extending the GIMP - Replies (3)

Hello, I just upgraded to 2.10 from 2.8 & I'm having trouble adding the G'MIC plug in that I had used in 2.8.  After installing G'MIC I get the attached message on starting Gimp. I click OK on this message, it disappears & Gimp starts normally but no G'MIC in the FILTERS menu. Any suggestions?

  How do I create a printable grid with scanned images in each sqaure?
Posted by: SamosSage - 01-11-2019, 02:51 PM - Forum: General questions - Replies (3)

Hello everyone! 

This is my first post, so bear with me if the formatting is a little wonky.  Big Grin

I am starting a project where I take small images and quotes and cut them into squares on an 8.5x11.00in cardstock. What I would like to do, but am not sure how to do, is to divide a layer in gimp into a grid, with boxes ~4x5 on the paper. Then, I would like to paste the scanned images I have into each of those squares, export, and print.

Using render>pattern has gotten me to a certain point, but it's not very printer friendly, the alignment seems kinda off, and I feel like I am reinventing the wheel. What would be perfect is if each square was its own instance, as in a separate layer so I can work within each box separately without grabbing other places as well; I am not sure if that's possible or over-complicated?

I am not totally new to GIMP, although I haven't used it in about 2 years.

  Suddenly copy changes brush
Posted by: marty39 - 01-11-2019, 01:42 PM - Forum: Gimp 2.8 questions - Replies (1)

I've been using Gimp 2.8.14p2 (January 9, 2015) for at least the last three months on a Mac running El Capitan. A few weeks ago it started doing something new, though I gather it's what's supposed to happen.

Until a week or so ago, I could copy and paste without changing the brush in any of the tool options. Now when I copy and paste something I have to change the brush from "clipboard" back to the circular shape I had before.

When I copy something from an image, I want to paste it, not change the brush. I want to keep the brush I had.

What changed, and how can I change it back?

  Display Size vs Pixel Size Problems
Posted by: blinkinhek - 01-10-2019, 06:12 PM - Forum: General questions - Replies (4)

I have recently moved to a Surface Pro. with it's fairly high res screen BUT the icons are not really legible or usable I can adjust some in settings BUT the Tool options dialog do not change.  Windows does provide a scaling factor in its settings, which helps some programs (many of which automatically scale their icons, menus, etc) but GIMP seems to ignore it.
Can anyone help?

  Handpainted effect
Posted by: Natrixx - 01-10-2019, 07:05 AM - Forum: General questions - Replies (2)

Hiya! I have an ordinary, square border in Gimp, that I'd like to give a handpainted touch, something like the attached picture. Not a big problem, I suppose, but I would love to hear your thoughts/tips on how I could achieve that.

  How to get image colors closter together?
Posted by: Acoustic - 01-10-2019, 05:36 AM - Forum: General questions - Replies (3)

To preface, I am colorblind. So many colors blend together for me, so I need some assistance on this. Working on a terrain and I have 2 different sets of textures, one far away and one close. They both need to be really similar in color. I created a palette from one and applied it to the other, but I am not sure if they are still close enough. If someone could get them closer (or tell me that they are as close as they'll get, as I am not sure) and tell me what steps you took, so I can replicate on the other textures. Or any general advice, as well. Thanks.


Two images as example.
