If I scale an image I know I will lose some quality.  Assume I scale an image to 3x.  I find that I over scaled it and then rescale to 2x the original size.  What does Gimp use for the basis of the intermediate scale?  Is it scaling down from the lossy 3x image?  Or does it have the original image in memory and thus scaling 2x from the original image resulting in a better quality scaled image?

Hi,
Please help, I can't follow some of the instructions in the user's manual. For example, You can add Brush-Pattern-Gradient icons and Active Image icon through Edit → Preferences → Toolbox: 

I can't find Preferences when I click on Edit on my MacOS Sonoma 14.0.  Please see the attachment.


Thanks very much for any help!

Hi y'all,

I'm wondering if you could answer me a riddle.

I've been working with game textures recently, and doing most of my precision editing in photoshop, and then copying from photoshop and pasting into gimp when they're ready.

I had no trouble doing this with the color textures, I'd paste into gimp, export as .dds and bingo, all good. The game would reproduce the texture on the models just fine.

BUT, when I tried to do the same with the opacity layers, I'd paste into gimp, export as .dds making sure to generate mipmaps, and then all of a sudden the opacity layer was nowhere to be seen. When I edit the game's original opacity layer .dds in gimp itself without pasting from photoshop, the opacity layer is then recognized by the game.

So my question is how do I paste from photoshop into gimp, making sure that I am not bringing any errant data along for the ride that might confuse the way the game renders that layer? Is there something I'm missing?

Thanks

I've poked around the source code but am having difficulties and am currently trying to figure out how white balance  / auto levels is performed. 

I think I was able to figure out gimp_operation_levels_map as the root for determining setting gamma but there is a bunch of contextual stuff I am missing.  

Example: I'm thinking gimp makes a copy of the xcf representation of the image and performs an update to that. Then there is a history of steps and one can jump back to an intermediate step.  

Via bimp, using some of the procedures out of pdb, i noticed that the intermediate steps are not necessarily saved and may be overwritten.  For example gimp-drawable-levels (to set gamma) followed by gimp-drawable-levels-stretch wipes out the levels gamma change whereas reverse order works.  And ditto for color-levels-gui. 

Anyway pointing me to something high level to get around the 15 levels of indirection used in gimp would help.

Thanks

The city authority cut down some old trees at the back of my house. The trees belong to them, and found to be diseased. A shame to see them go, someone counted the rings and came up with 164 years old.

   

But it reminded me of this cartoon, About what bears do....
