Hi.
First sorry if my word choise is confusing, Im an amateur so I might not understand some term.
Im trying to edit game asset. How do I make a cut on texture to precisely match the alpha channel shape? Using fuzzy tool can be done but it only make a solid cut, some semi transparent will made into solid cut.
In layman's term, how do I make alpha channel as a cast and use it to cut a flat texture so that it will have the exact same transparency?



Edit: Some illutration what Im trying to do.

There is a gif file, when I input it in GIMP and output it as another gif, it is always obviously larger than the input gif. Why? I tried some methods to optimize it.

Sorry I am not able to add an attachment.

Hi!

I'm new to the forum and scripting, and have little GIMP experience.

I am working on my first python-fu script, which opens jpg files, changes them, and saves to new jpg files.

How one would load a jpg file while preserving its original 'sRGB' color space? When I open the file through the GUI, GIMP asks me if I want to keep it or convert to 'GIMP built-in sRGB'. However, when my script loads the file with pdb.gimp_file_load(), It just converts it automatically.

I'm running GIMP 2.10 on Debian.

Thanks a lot!

Is there a way to save a file with pdb.file_jpeg_save(), while overwriting the 'software' exif tag?

Even though I set the tag with pdb.gimp_image_set_metadata(), the resulting file has 'GIMP 2.10.32' as its value.

Thanks a lot!

Hi

I'm sorry for my bad English. I am really incompetent in advance Gimp using.

I would like to modify the "down right corner" symbol of 'Note_Cymbal_Yellow_Sizzle.png' in order to look like the 'Note_Cymbal_Miss_Sizzle.png' symbol but I don't know how to do that. I would copy/paste the "down right corner" symbol in the other file to obtain the 3 other corners.

I imagine it's a basic manipulation for an expert.

Could someone do that for me please ?

No idea if this has been mentioned before or not. Could you put all the solved questions under another topic so people can look there first - like a FAQ or something?

I'm sure that due to an upgrade from GTK2 to GTK3, the default responses (i.e., the active button) when a pop-up dialog displays changed between GIMP 2.8 and 2.10.  Even after a few years, these changes still bother me.  Is there any way, external to the GIMP code itself, that the default responses for a given dialog can be set?  I'm hoping that there is some kind of external file where this might be set.  I'm just not familiar enough with the GTK internals to know if this is possible or not.

Thanks for any insights.

A good report here:

Hello,

I have an indexed PNG and want to edit the transparency of it - my problem: Transparency is either 0% or 100%

What I'd like to have: I'd like to add a transparency value to each of the 255 indexed colours - so colour 1 is totally transparent, and the others transparency should be set to something between 50% and 90% depending on their brightness (white -> 90%, black -> 50% or something similar) - (I wouldn't mind to edit the 255 colours by hand if necessary).

I did something like this few years ago, but can't reconstruct how I did it - though I ended up with a 24 bit per Pixel PNG, so maybe it's not possible to have an indexed PNG with varying degrees of transparency!?

If I open the indexed PNG it shows two channels, one with the image information and the other with transparency information is a black or transparent thing with nothing inbetween (seems to be just 1 bit of info per pixel) - so maybe it's possible to change that part (and have 1 byte per pixel as well).

Thanks for any hints.

So I recently got a surface laptop studio and the pen to go with it, it's a touchscreen and it's specifically designed for drawing, but it would seem that gimp can't distinguish the pen from the cursor, and thus it's not detecting any pressure, nor does the other side function as a second pen. Any way to fix this?
