  Free-handed/Path-tool selection/inverse selection does not work
Posted by: rouxssignol - 04-03-2020, 08:02 PM - Forum: General questions - Replies (4)

Hi guys! I've been trying to get a proper selection/inverted selection to crop out in Gimp 2.10 for about two hours now. I've done all the advice I've seen on a variety of forums: press Enter to activate selection, deactivate/activate Opencl, all that jazz. But it still doesn't work. Any clue why? Maybe I'm doing something wrong with the layers, but since I'm very new to Gimp, I'd value any piece of information I can get.   Blush

Thanks!

PS: I've included a screenshot of what I was trying to do. Essentially, I wanted to invert select to crop out the image around the selection (main figure) but every time I tried, I'd get the exact same image, only slightly cut out on the border.

  Falling snow animated Scheme Script for Gimp
Posted by: JimmyMarco - 04-03-2020, 01:40 PM - Forum: Extending the GIMP - Replies (15)

Hello,  Smile

I'm a french guy, newly registered on the website.
I have finished today a Scheme script to make a 25 frames animation with falling snow effect :

The Falling snow script in a Zip file

[Image: FallingSnowWindow.jpg]

Exemple with the default parameters below:

[Image: snowDefaultParameters.gif]

With flakes Opacity on 70/100 :

[Image: snowOpacity70.gif]

Another exemple with first flakes size 1 and 7 layers of flakes :

[Image: snow7layers.gif]

With difference size between two layers set on level 2 instead of 1 in previous exemples :

[Image: snowDifferenceLevel2.gif]

With Wind force = 1 :

[Image: snowWindSmall.gif]

With Wind force = 2 :

[Image: snowWindMedium.gif]

With Wind force = 3 :

[Image: snowWindStrong.gif]

Wind force can be set in the other direction using -1 -2 and -3 values.

Falling snow effect can also be applied on selected parts, and you can use special lightning effects using layers mode and opacity.
Animation display automatically open in the end of script to show what it looks.

Tell me what you think about this script, and if i can better it.

Good test.  Wink

  Controls
Posted by: RolandGent - 04-03-2020, 11:31 AM - Forum: General questions - Replies (2)

Ok I'm new to GIMP and learning via tutorials. I have version 2.1, the only problem is some of the control seem to have disappeared, maybe I clicked something. But on the left side of the screen where you are supposed to be able to change bruch sizes the controls are not there

Did I click something wrongly?

  Modify Crosshairs Script
Posted by: akovia - 04-02-2020, 11:56 PM - Forum: Scripting questions - Replies (6)

Could this script be modified to work on the image and not the active layer?

I have a shortcut already for crosshairs per layer, but would like to add a shortcut modifier to work on the image and not the layer. I poked it with a stick for a while and couldn't get it to work.

  Crop Canvas?
Posted by: akovia - 04-02-2020, 09:49 PM - Forum: General questions - Replies (6)

I'm looking for a way to use the crop tool (or similar) to only crop the canvas size and not the image itself. 

To explain a bit more, I have quite a few crop presets that have all the aspect ratios of the artwork I create. Most of the time I'm trying to compose an image to fit within the restraints of a ratio. If I use the crop tool and I don't get it exactly right on the first crop, I have undo and try again. Or I can use the better solution of dropping another copy of the image as another layer and then I can move the full image around as needed with the correct canvas ratio acting as a viewport.

I think it would be incredibly handy if you could use the crop tool to just crop the canvas to create a viewport at the preferred ratio, and leave the existing layer/s as is. (A modifier key for instance) I think this would go hand in hand with the new Out-of-canvas viewing and editing features.

Am I overlooking an easy way to do this already? 

I have already requested a feature to mask the canvas padding and might help to visualize what I'm trying to say.
https://gitlab.gnome.org/GNOME/gimp/-/issues/4833

Just wanted some feedback before requesting another feature.

  Configure gimp to save jpegs in format compatible with older programs
Posted by: masteratarms - 04-02-2020, 10:09 AM - Forum: General questions - Replies (4)

I've seen it mentioned about how some settings will break compatbility with older programs but can't remember where that was.  I'm missing the jpeg configuration options in the export as dialog.  Is the option under image?

Thx

  I'm trying to copy a selection from one image layer to another
Posted by: jimindt - 04-02-2020, 02:56 AM - Forum: General questions - Replies (3)

I've got an original image of my 1850 great great grandmothers photo. I made a layer copy of  it, made changes on that Layer(2) and made another copy of that layer(3) and made even more changes on the third Layer.
When I  cleaned up the third layer, I took a bit more than I needed to out of it. I want to go back to the second layer and copy a section of it and put it onto the third layer.

I've tried this which I found somewhere:

  1. Select what you need - I did this with Free Select on the second layer
  2. Select - Save to channel. I did this on the second layer
  3. Ensure the newly created channel is selected and Edit - Copy (Ctrl+C)
  4. Go to the image where you want to insert the selection (I clicked on the the third layer)
  5. Open “Channels” and create a new channel (a button at the bottom or via the context menu) - did this on the third layer
  6. Ensure the newly created channel is selected and Edit - Paste (Ctrl+V)
  7. Open “Layers” and anchor the floating layer (a button at the bottom or via the context menu)
  8. Open “Channels” and replace the selection with this channel (a button at the bottom or Channel to Selection in the context menu)
Get lost/confused around step 5. What exactly is the Channel doing? If in step 6 the Edit/Paste creates a 'floating layer' which contains the area I copied in Step 1, what exactly is Step 6 telling me/doing as I thought the anchoring of the floating layer (step 7) merged the selected area into layer 3?
In step 8 what selection is meant, and which channel is being referred to as there are two channels?

And with all of that, I still don't see my selection anywhere.

  yellowish vertical bars across scanned image
Posted by: tommik128 - 04-01-2020, 11:55 AM - Forum: General questions - Replies (3)

Hi guys,

I am really struggling to get rid of the yellowish tint across this scanned image - seen as vertical bars going through different areas. I was trying to use Fuzzy select tool, Free select tool + all options under Colors (Temperature, Curves...) but I need more knowledge. What is the way to sort of replace certain color spectrum (in this case yellowish pixels) whilst not affecting the other parts of the color spectrum - I mean so that I do not end up with areas contrasting with the rest of the image. Basically how to get rid of the yellowish part of the color space in those vertical bars and no more?

Thank you.

  GIMP Chrome extension
Posted by: dlnw52 - 04-01-2020, 12:33 AM - Forum: General questions - Replies (1)

Has anyone used this extension on a Chromebook? I am now doing remote teaching and my students have Chromebooks at home. The app has a very narrow canvas window. If I make the toolbox and layers panel visible we don't see much of the canvas. Any solutions? Thanks.

  Missing Fonts - 2.10.14 - for Mac OS?
Posted by: Barbara Buffington - 03-31-2020, 05:48 PM - Forum: OSX - Replies (11)

I have discovered that in the most current download - 2.10.14 version - for Mac OS - many of the Fonts are no longer available as they were in the former versions.  For example Mistral and Curlz MT, which in particular I used often in the past, are showing strange symbols instead of the appropriate lettering in the text tool listing and in text boxes I create on images.  Can these Fonts be recovered and if so how can I do that?  Thank you for your kind attention and response regarding this disconcerting snafu.
