  Setting GTK Dialog default answers
Posted by: cjsmall - 11-18-2022, 11:59 PM - Forum: General questions - Replies (4)

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.

  Adding/Editing transparency in an indexed PNG
Posted by: out-of-mind - 11-18-2022, 04:23 PM - Forum: General questions - Replies (3)

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.

  Surface Laptop Studio pen not working
Posted by: CubeGamer647 - 11-17-2022, 04:27 PM - Forum: General questions - Replies (1)

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?

  First time with Gimp and drawing tablet
Posted by: PixelSystem - 11-17-2022, 02:18 PM - Forum: General questions - Replies (1)

Hello,
I am trying to get a XP PEN Deco 01 v2 to work with gimp on win10.  I have downloaded and installed their drivers.  However when ever I put the pen to the tablet in gimp it switches from the pencil tool to something that gives the attached image.  I have no idea what is going on.  (also please feel free to recommend any configurations as I am new to art with a drawing tablet.  I tried doing traditional but I find digital a lot easier for me)

  Print image scan larger than actual size
Posted by: fixit7 - 11-17-2022, 04:37 AM - Forum: General questions - Replies (6)

I scanned an insurance card and want to print it larger than it's actual size so the picture is easier to read.

I tried scanning to high dpi with no luck.

Is there a way to do that?

  Painting
Posted by: sallyanne - 11-17-2022, 01:32 AM - Forum: General questions - Replies (2)

I have had this problem for awhile now and thought I may have been able to see what the problem is so didn't post about it before.
Whenever I paint I rarely get a full 100% opaque mark with just one stamp. I have made sure my opacity is 100%  Hardness & force also I have at 100%. I am wondering could it be my dynamics?
Maybe it is the brush? Although I do not always use this brush. I have noticed this with other brushes as well. My brush and size are still set from some healing/cloning I was doing.

  G'MIC Mandelbrot Filter Error (Re-Edited)
Posted by: pypedreams - 11-16-2022, 05:55 PM - Forum: General questions - Replies (4)

Hi Everyone,

I recently posted a problem with G'MIC and kept it brief, but haven't found a way to resolve the filter error. Below is more
detailed description.

While using the G’MIC Mandelbrot / Julia filter, my wireless mouse seemed to randomly change the filter settings, I simply turned it off and on again which fixed that problem, but when clicking OK I now receive this message:

“Error in ./fx_mandelbrot/ *** Command ‘input’: File ‘0’, format does not take any input options (options ‘0’ specified).”

The mouse definitely created the fault, could someone please help.

Thanks

Question Swapping two colours in an image
Posted by: whitelined - 11-16-2022, 02:24 PM - Forum: General questions - Replies (8)

I'm currently trying to change a logo in gimp. I need to do two things, make the background transparent so it can be inserted into another document and swap two colours around. I've managed to it transparent with some decent results with the anti-aliased edges using Colour to Alpha. The next thing is changing the colours - I can't figure out how to change them and make it look decent with anti-aliased edges. If I fill, it looks terrible. I just need to swap the pink for the white. What's the best gimp tool to achieve this?

Many thanks
