  Line not showing
Posted by: Four brick - 08-31-2017, 01:05 PM - Forum: General questions - Replies (3)

Using Gimp on apple Mac, loaded new canvas,  and when drawing a line, the line doesn't show, although the pencil logo shows. 

Anybody got any idea what I am doing wrong?

Is it the software or the soft user?

Photo Cleaning scanned magazine pages
Posted by: MrNiceButDim - 08-31-2017, 05:19 AM - Forum: General questions - Replies (15)

I'm totally inexperienced with GIMP but I chanced upon this recipe that would meet my needs for a rather big project I'm currently doing. It's about cleaning scanned magazine pages where the print on the back side shines through the thin paper making the reading less enjoyable.

GIMP Recipe:

  1. Open a file.
  2. Convert your document to grayscale: Image - Mode - Grayscale.
  3. Select the background color: Select - By Color, click with mouse pointer on the color of the background.
  4. Invert the selected color: Select - Invert.
  5. Copy the selection: Edit - Copy.
  6. Create a new file: File - New.
  7. In the dialog of a new file, in field: Advanced Options choose: Fill with: White, hit Ok.
  8. Click anywhere in the window of the new opened document, just to choose it.
  9. Paste the content of a clipboard: Edit - Paste.
  10. Add a new layer to enhance the black text: Layer - New from Visible, in the layer's palette, in field: Mode: choose Multiply.
  11. Combine two layers: Layer - Merge Down.
  12. Save the result as a JPEG file: File - Export As, choose jpeg and set the quality at least 60.

I have a couple of questions.
  •  When getting to "Combine two layers: Layer - Merge Down." the Merge Down option is grayed out so I can't apply that step.
What could be the reason? And why does it say "Combine two layers" when there is three?

1.Floated selection (Pasted Layer)
2.Visible
3.Background
  •  When selecting a background color to be - erased/turned to white - what would be the best way to pick a wider range of grayness than the rather sparse instruction the recipe suggests "By Color, click with mouse pointer on the color of the background."

  red/blue swap (Gimp 2.9)
Posted by: E_T - 08-28-2017, 01:33 PM - Forum: General questions - Replies (2)

I'm trying our IR photography and use Lightroom, but I've been using Gimp to swap the red and blue channels.  Works great, but I noticed that it doesn't seem to work right if I export the image from LR in Adobe Pro RGB colorspace.  When I do this, and swap the colors in Gimp, they look off.  The sky should be blue, but it looks more blue/green.

If I export the image in sRGB, the swap works as it should.  Any idea why this happens?

  Tool Preset Tagging Problem
Posted by: JackAttack - 08-27-2017, 09:46 PM - Forum: General questions - Replies (8)

Hi!
I am having a problem with tagging tool preset. Let's say I have two brushes (Sketch Pencil, and Oil Brush) that are not related or even next to another in the tool preset window. Now, let's say I want to tag Oil Brush with a new tag, painting. I click on the Oil Brush Preset, and type painting into the tag window, then press Enter. Now that tag appears in the tag box. Then, if I filter my presets by "painting", instead of Oil Brush showing up, Sketch Pencil shows up. If I click on sketch pencil, "painting" does not show up in the tag box, but it does show up in the Oil Brush tag box. What is going on? 
Thanks for all your help in advance!

  Gimp 2.9.7 Blend tool
Posted by: rich2005 - 08-26-2017, 11:58 AM - Forum: Gimp 2.10 - No Replies

Updated today to Gimp 2.9.7 from 'buntu ppa

This is the blend (gradient) tool, The ability to paint a gradient directly onto the canvas is not new, but I do not know how long editing a gradient in place has been there. Adjusting the colour stops, now shows up straight away in the tool.
The gradient file - something.ggr does of course, have to be in your Gimp profile gradients folder, to be editable.

Developers are threatening to include this in an updated Gimp 2.8.(24?) sometime.

  Gimp on go slow
Posted by: sallyanne - 08-26-2017, 11:17 AM - Forum: General questions - Replies (12)

For a while my browser has been crashing on me or 'not responding' but eventually it did. I think I have fixed that now by resetting the browser but now Gimp is doing something very similar. Nearly every-time I run a filter within gimp (It doesn't seem to happen with GMIC) the status bar at the bottom doesn't complete. Sometimes the operations complete and often they do not. 


I don't have a screensaver running on my computer so that is not using up room. I have only used about half my storage too - over 200GB is left on it. Surely I don't use 200 hundred GB to browse the net? My question would be  - what do you think the problem is?

I am using a relatively new gimp 2.8.22
Am afraid to add any more scripts now incase my pc cannot handle it.

My OS is Windows 10 Home 32 bit
