need help python plug-in
I am trying to help someone on my forum to automate some steps
and one of the steps is colortoalpha
so I used
pdb.plug_in_colortoalpha(image,active_layer,color) but it isn't producing the same result as doing it from front end.

but if you do it through the front end there are two other settings one of which is the transparency threshold.

How do I perform the same settings as the front end specifying those 2 extra settings in addition to color?

Thanks in advance.

How do I set a default directory for saving work to? I looked in Edit > Preferences and I could not find anything about storage or default work directory.

I'm using GIMP 2.10 on Slackware 14.2-current 64bit. I tried to post this to the 2.10 forum, but for some reason, I don't have the button to start a new thread on that forum. So, I'm asking here.

When I start GIMP, the window fits on my screen and I can see all the tools. It's been working fine for weeks/month. Just today, when I open any of the projects I was working on, the window expands vertically to the point where I can't see the bottom of the tool options or the zoom tool. I know I can access the zoom through the View menu, but I prefer to just change from the tool at the bottom of the window. I haven't tried with each project I've been working, I'm up to 8 or 9 already, but the first 3 that I tried have had this problem.

I've quit and restarted the app several times now.

I went into the View menu and tried the Shrink Wrap and Fullscreen options to see if I could manipulate the window size, but after clicking on those, the window changes and if I click again to undo the change to the window, the window goes back to the bottom bleeding off of my screen.

I went to the desktop toolbar/taskbar and right-clicked on the window there to see if I could resize that way. I can only change the horizontal size, not the vertical size. If I used the full-screen/expand arrow in the upper right of the window, the top border of the window disappears and I can't get back to the arrow to turn off full-screen. And the bottom still doesn't show up, it's bleeding off of my screen like in all of the other sizes/positions.

The dimensions of the projects I'm working on are 2550 pixels wide x 3550 pixels tall. I had the zoom at 18% to view the whole thing and also at 100% to work on some details. 

Even when I open images and layers that I haven't edited yet, the window immediately shift to the unwieldy size.

How do I get the window to stay the same size after I open a project as it was when I first open the window?

Is there an error in the filters / Alpha to Logo / Neon script ? After using the script on a text, part of the text on the center wiped out. Any suggestions ? Thanks in advance.

I would like to change this line into a half circle?

Also can I control where is the center of this half circle?

   

I have tried several things in order to export this image with a transparent background, i.e. select "Export As", selected PNG as format, checked AND unchecked "Save background color", same with Gamma, et al...nothing's working

File attached, and any help is sincerely appreciated!!

I used 2.10.14 to create a palette from an image. It has 256 colours and it is sorted in a random manner. Can we sort it automatically in such a way that similar colour shades are grouped together

Do you think that it is worth using Webp for animated images through GIMP 2.10 ? I found how to do it, but I am not sure whether I will be able to upload one here, or Imgur.

I have a cartoon picture that came with an outline. I want to thin the outline either by making the inner color areas bigger or the outline thinner, it doesn't matter. Is it possible to some way negatively stroke a selection? I tried to put a minus sign in the pixel line width section but it just auto-set to 0.

I want to vary my line thickness as I paint to match a style of an image, but can't seem to find how to input this setting I'm reading about, varying the mouse size with how fast you move it. I'm sure one of you GIMP wizards must know TIA
