  Wrong version on 3.0.2 splash image
Posted by: NickJP - 03-26-2025, 06:21 AM - Forum: Gimp 2.99 & Gimp 3.0 - Replies (3)

Not that it really matters, but I just upgraded from 3.0.0 to 3.0.2 (Windows) and noticed that the splash graphic that displays on screen while the program is loading still says 3.0.0 in its bottom right hand corner...

Photo GIMP PDFs have transparency
Posted by: waltonm - 03-25-2025, 06:24 PM - Forum: General questions - Replies (13)

I am using GIMP 3.0.0 on Windows 10 system

I made a PDF (Export as PDF) from a multilayered file. It had transparency (Acrobat > Preflight > List transparent objects). I flattened the file, exported as PDF, and it had transparency.  I exported the flattened file to JPG, then exported the JPG to PDF, and it had transparency!

To further focus in on the potential solution or problem, I:

  1. created a JPG in XnView
  2. opened it in GIMP, then exported it as a JPG
  3. closed the file, then opened the GIMP produced JPG
  4. exported it to PDF, using default settings
  5. checked the transparency in Acrobat: "Transparency used." (A, in attachment)
 

To test this, I repeated the steps using Affinity Photo, I:
  1. used the JPG from XnView
  2. opened it in Affinity Photo, then exported it as a JPG
  3. closed the file, then re-opened the Affinity Photo produced JPG
  4. exported it to PDF/X-4, setting it to permit transparency/layers, if there is any
  5. checked the transparency in Acrobat: "No problems found." (B in attachment)

I have repeated this in GIMP using Print > Print to doPDF, cutePDF, AdobePDF, all with no transparency. 

Some printers will reject PDFs with transparency.  I am trying to produce a PDF from GIMP with no transparency and no other programs (like Adobe PDF).  Is that possible?

  How do I move my toolbox?
Posted by: harrisongrey - 03-25-2025, 06:15 PM - Forum: Linux and other Unixen - Replies (4)

On Ubuntu, currently running 3.0.2.  I had to fresh install to get to .2 otherwise it kept crashing on brush selection, but in doing so it wiped my preferences.  I'm just trying to figure out how to get the toolbox onto the right side of the screen.  Used to be you could turn off single-window mode, move the toolbox window, and then turn back on single-window mode and it would save the position, but that doesn't appear to work anymore.  Anyone know the current method?

  Did GIMP 3.0.2 Break Plugins Again?
Posted by: n3306tx - 03-25-2025, 04:10 AM - Forum: Scripting questions - Replies (3)

Apparently GIMP 3.0.0 had an issue with the initial installation file where the python console was missing and python plugins were affected and not showing in the menus.  GIMP 3.0.1 was released and fixed this problem.  GIMP 3.02 with additional bug fixes was released and now python plugins no longer are showing in the menu.  I reinstalled GIMP 3.0.1 and the plugins are back in the menus.

  Alternative to Drawable.get_tile() for Gimp 3?
Posted by: joeyeroq - 03-25-2025, 01:21 AM - Forum: Scripting questions - Replies (6)

I'm trying to port a Gimp 2 script to Gimp 3 and got most of it figured out by trying stuff out in the python console.

    sample -- sample every nth pixel of layer tile
    minimal_dimensions -- minimal dimension of object to be placed in "objects" layer group
    '''

I've hit a snag with lines 65 and 129 with "Tile = layer_offscreen.get_tile(False, tile_row, tile_col)". 
in Gimp 3 "drawable.get_tile()" doesn't exist, what is the alternative to this?

  Keep exif-orientation on import
Posted by: Pflichtfeld - 03-24-2025, 10:44 PM - Forum: General questions - Replies (9)

Hi guys,
Problem: upright picture (portrait) of a door. Exif in original jpg is right,top.
I send it to gimp. The door now is shown in landscape, the exif now is changed to top,left.
I'm not sure, but maybe once there was a popup how to threat orientation of origin.
But now this popup is gone and I cannot find the option to change this behaviour.
Any help?

  menurc file problem with Gimp 3
Posted by: migf1 - 03-24-2025, 06:04 PM - Forum: Gimp 2.99 & Gimp 3.0 - Replies (1)

Hey all,

I tried on Reddit yesterday but no-one replied, I hope someone can help here.

When I installed Gimp 3.0.1 along side my existing Gimp 2 installation on Windows 10, the Gimp 3 installer picked up all*rc files from my Gimp 2 installation, however when I deleted the menurc file from Gimp 3's path (a.k.a "C:\Users\...\Appdata\Roaming\Gimp\3.0") not only the keyboard shortcuts were not reset, but also the menurc file was not recreated in the above path (as it does in Gimp 2). I even tried copying another menurc file of mine, with different keyboard shortcuts, but Gimp 3 fails to read it.

In short, i'm stuck with the custom keyboard shortcuts I had in Gimp 2, and I cannot reset them in Gimp 3. Also, I'm not able to use any menurc file (I have a couple of them with different sets of custom keyboard shortcuts).

Is there any kind of cache file I need to delete or something? Is there any other path I need to look at, where Gimp 3 picks up the old menurc file from? How come it does not recreate the menurc file when I delete it?

Btw, the controllerrc file works fine (it gets recreated when I delete it, I can copy there other versions of it and Gimp 3 loads it, etc). Is there a bug specifically for the menurc file in Gimp 3?

Thanks in advance.

  resynthesizer 3.0
Posted by: denzjos - 03-24-2025, 05:24 PM - Forum: Gimp 2.99 & Gimp 3.0 - Replies (8)

I download resynthesizer 3.0 and put the script files in the GIMP 3.0 script folder and the exe file in the GIMP plugin folder. I am using GIMP 3.0.0-1 and find Resynthesizer in the menu, so GIMP finds it. When I try to use Resynthesizer, I get the menu, but when I activate the plugin, I get an error, and the plugin stops. Is the plugin ready for GIMP 3.0.0-1?

  GIMP Foreground (or Background) Color Select
Posted by: oyearian - 03-24-2025, 03:31 PM - Forum: Gimp 2.99 & Gimp 3.0 - No Replies

In GIMP 3.0.0 (Mac OS 13.7.4 Ventura) clicking on a color in the "Change Foreground Color" dialog immediately causes the dialog window to disappear. The color is changed, yes, but it seems you have to do it incrementally, step by step, rather than making all the guesstimate changes and then clicking "Okay" as it was in 2.10. I hope that this is a bug rather than a feature. I hope even more that I've simply overlooked a setting somewhere.

  Text Layer Edit Disappointment
Posted by: oyearian - 03-24-2025, 12:32 PM - Forum: OSX - Replies (1)

The option to inset symbol or emoji under the Edit menu is gone. It's a relatively minor thing, perhaps, but I wish I still had it. Why take options away with the new version (3.0.0, in my case)?
