Hi,

Sorry in advance for the length of this post. TLDR version is that exporting an image from GIMP to TIFF format yields weird results.

All of the work described below is taking place on a Dell laptop with Intel x64 processor running 64-bit Windows 10, darktable 5.2.0, and GIMP 3.2.4. My overall goal is to create a composite TIFF image comprising four cropped photos side by side, and then make a print.

I have four cropped photos that were post-edited from camera raw using darktable and exported to TIFF files using darktable settings shown in the attachment darktable_export_settings.jpg. I checked the darktable exports using Windows photo viewer, and they all looked fine.

I next imported the four photos into GIMP, converting the color profile to the built-in GIMP sRGB. I created an appropriately sized empty image and pasted the photos into it, each on a separate layer, and set the X offsets to arrange the photos. Lastly, I put a white background layer on the bottom to show white separator regions. All layers were set to 100% opacity. The attachment GIMP_preview_scrape.jpg shows the contents of the workspace image preview after all of the editing. The preview looks exactly as I intended.

I then exported from GIMP to a new TIFF file using File->Export As... with the settings shown in attachment GIMP_export_settings.jpg. I think the important thing to note is that I exported uncompressed and did not save layers. This is where the problem shows up. I opened the new TIFF file with Windows photo viewer, and it was extremely grainy (see attachment GIMP_export_preview.jpg).

I tried repeating the entire process but exporting from GIMP to JPG, and the final image was flawless. Obviously I could resort to using JPG instead of TIFF to make my print, but I really want to understand where I went wrong in this process.

Any suggestions?

Thanks,

Mike

Hi,

[GIMP 3.2 python API]

I'm trying to iterate over all the coordinates of an image, and create some calculated pixel values on a new layer.

I'm currently using the Gimp.Drawable.set_pixel() method, but its very slow (and supposed to be).

I'm struggling to find the right way to do this. I think there was a concept called "regions" in GIMP 2.xx. I understand I have to use a Gegl.Buffer. But from there I'm stuck
I can't find any definition, or just circular definitions, of what a Gegl buffer is, or any other concept. That's what makes things really difficult. 

Does a "buffer" represent the whole drawable? And if it is, how do I extract just a tile and iterate over the pixels?

What is a "shadow buffer"?

What is a "handler"?

What is "the abyss"?

Thanks!

Hi everyone,
I often work with SVG icons and logos, and I'm looking for an easy way to change SVG color online without manually editing the SVG code.
My ideal workflow would allow me to:

• Upload an SVG file
  
• Change one or multiple colors
  
• Preview the result instantly
  
• Keep the original vector quality
  
• Download the updated SVG without losing transparency
  

I can't get the tool options dialog to stay. As soon as I click somewhere else on the screen it disappears and I have to load it again.

Hello folks,

Long time user of GIMP although still fairly limited experience wise, one thing I keep meaning to look at is how to change the default 'save' location for new xcf files.

Ai summary and YouTube suggest the 'bookmarks' option but on my OS (Linux LMDE 7) there doesn't seem to be that option, just the regular home, documents and so on.

My folder structure is now getting fairly complex so would be a great help and time saver to skip a few selections each time.

Edit: just to add, I do have the 'bookmarks' option on file explorer to it is there just not in the smaller GIMP save window.

Thanks

First of all, thanks to everyone who's been helping me along with my latest book cover.

As I posted in another thread, here's where I've gotten to with the front (I have the typography in another file and will layer it in when the graphics are complete).

   

I'm at a pretty good place, I think, with the color matching, but the Fachwerk background needs work to make it less one-dimensional and more lively. I'm aiming for the same background effect I had on the first book in the series. Its front cover looks like this:

   

The blueprint background is a vector image licensed from Shutterstock and it came as you see it, with the highlights and shadows already on. I just moved it around behind the heads of my couple to get the halo effect I wanted.

The Fachwerk photo, on the other hand, was evenly-lit, with no variation of light and shadow. I think I can use Filters > Light and Shadow > Lighting Effects to give me some highlights, at least. But I'm having a hard time doing it correctly. I'm able to go into the Light tab and use the blue dot to add point-source glow, but . . .

• How do I locate the light points so they're at the right position behind the models' heads? Yeah, I see the boxes with the X and Y axes, but I have no idea how to find those numbers in relation to the layer above.
  
• How do I make the glow radius smaller so I only get the light I want? Every time I try, even when I turn the intensity way down, it over-lights and overwhelms the whole background.
  
• I'm wondering why the Bloom tool options box keeps coming up, when I didn't select Bloom in the first place. I wouldn't mind experimenting with it, but when I try to use the sliders or enter a parameter, nothing happens.
  
• Would it help if I chose Transparent Background in the General Options dialogue? Would that create a new layer so I can move the light around on the Fachwerk image and put it where I want it? Or would that be "Create New Image"?
  
• Are there settings in Lighting Effects where I can create negative light, so to speak, and selectively put parts of my background in shadow? Or would that be a different tool?
  

   

My preference for basic use, transferred from W10 PC.  How do I get rid of templates I have accidently made by clicking on ‘Create Template’, instead of  ‘Export As’.
Tried:
 - uninstalling  and removing every folder I can find, including any lurking file hiding in Roaming ‘containing settings’.
- deleted Templaterc file.
- Windows dialogues > Dockable Dialogues >Templates. None of the red highlighted files  show to be able to deleted, just 640x480 etc, A3 (300ppi) etc.
 
Thanks for any help.

Hi, is there a documentation on how to theme gimp 3.2? In the screenshot you can see how far i could progress on my own. Gimp now looks a lot friendlyier and more usable to my taste. And its blazingly fast on linux with 64 GB of ram. 

I did found out that the toolitem group can be acessed from css with:
