Gimp suddenly doesn't see my scanner |

I've reinstalled the printer-scanner and connected it to the wifi again. Twice. Driver is up-to-date.
Canon mx490
Gimp still sees the printer, but not the scanner.
It was working fine yesterday. My wife's computer sees it.
My device manager now calls the printer-scanner "Unknown Device"
IDs it as a printer, locates it on the M490 series with a long number after it.
Says it is working properly.
Any help?
Thanks

Freshly-Built Gimp 2.10 segfaults upon startup |

Esteemed Colleagues:
I just built Gimp 2.10 from source and it crashes upon startup, as
soon as it tries to load the pagecurl plugin. Sometimes the crash
appears to occur upon loading the screenshot plugin, but I think that
is because screenshot is the last plugin that is loaded before loading
the pagecurl plugin. I think pagecurl is actually the plugin causing
the crash. Gimp is multithreaded so the exact moment when the main
window is unmapped and the error message is printed is indeterminate.
The error message is
g_param_spec_internal: assertion 'g_param_spec_is_valid_name (name)' failed
/gnu/bin/gimp: fatal error: Segmentation fault
and it seems to be coming from gimp_wire_read(). There is nothing
weird in my environment to which the crash can be attributed; the
crash still occurs when gimp is invoked after "env - DISPLAY=$DISPLAY".
(Parenthetically, building gimp from source was a nightmare. Gimp
2.10 required newer versions of, inter alia: glib, gtk, babl and gegl
than I had available thru my package manager, so I had to build those
from source too, and, in several cases, the libraries on which they
depend. The gegl build kept failing until I built a newer version of
gobject-introspection than the one I had, and then rebuilt babl using
the newer version of g-ir-scanner. This was, of course, completely
undocumented.)
Segmentation faults are common when you build software with a
PKG_CONFIG_PATH variable that does not correspond to your explicit or
implicit LD_LIBRARY_PATH when you run it, since you are linking
against different subroutines than the program was built to expect
(proper "-rpath" arguments in the pkg_config .pc files would fix that,
but the .pc files only contain -L arguments and not -rpath arguments,
I have no idea why). This seems, however, not to be the case here.
When gimp crashes and the debugger window pops up, it reports:
using GEGL version 0.4.26 (compiled against version 0.4.26)
using GLib version 2.65.1 (compiled against version 2.65.1)
using GdkPixbuf version 2.36.5 (compiled against version 2.36.5)
using GTK+ version 2.24.32 (compiled against version 2.24.32)
using Pango version 1.42.3 (compiled against version 1.42.3)
using Fontconfig version 2.13.92 (compiled against version 2.13.92)
using Cairo version 1.14.8 (compiled against version 1.14.8)
So -- at least with respect to those seven libraries (all of which I
had to build from source in order to be able to build gimp 2.10) --
gimp is using, at run time, the same version of the library that it
was built to expect.
How do I build a Gimp 2.10 binary that I can get to actually function?
I have no idea what the pagecurl plugin does, but I suspect that I
would be happy to live without it. I do not, however, see a configure
option for declining to build it.
As always, thank you in advance for any and all replies.

Unable to save as *.jpg or *.png |

I just installed GIMP 2.10.20 today (8/19/2020) to take the place of Photoshop. So far I am unable to get GIMP to save a file as either a *.jpg or a *.png file type. The File Saveas seems to show it is doing it, but when I look with file manager it is not anything but the GIMP native file type. My operating system is Windows 10.
I was able to import an image from my all-in-one printer/scanner, so at least that worked OK.
I found a few things on-line that were instructions on how to get GIMP to save files as *.jpg and *.png, but I cannot get it to work. I do not find any GIMP files under User/my user files/ that have any GIMP listing. I am fairly new to Windows 10, so that could be part of my problem.
I need detailed instructions if possible.

256-color-indexed(png|gif): missing transparency |

hey, i've already posted about this problem over on GIMPChat, although for the sake of inclusivity, i'm asking here too. Also, it looks like search functionality is busted atm, so I can't tell if this has been asked before and so i'm going ahead and posting my question...
The question is about how indexed color is represented at the data level in an exported image(png, gif), and what is the best way to export indexed images?: ¿num colors?, ¿remove unused colors from map? -- i guess those are the choices.
Really, it all comes down to a problem i've had a few times now when trying to export an image(png or gif) as 256-colors indexed. the problem is it keeps adding a background color, and removing my transparency, and no matter how hard i try i have not been able to fix the problem while maintaining a full 256-color palette. here's an example:
if you look in image properties you will see it is labeled 256 colors, and there is still transparency in some layers, although it seems impossible to remove my background color in layer 1 or 5... above was actually my 2nd attempt to remove the background using GIMP_2.10
Here is my initial fail using GIMP_2.8:
...funny thing though, the problem disappears consistently when i choose fewer colors. see here(128 colors):
What is the cause of this problem? Also, why does gimp default to 255 colors? I've had it explained to me that it is because gimp represents transparent as a color too, and so i must decrement by one; but then why is there still transparency in some of the layers in my 256-color gif?
A full explanation would be much appreciated! I like to index a lot of my published work(for various reasons), but I also like to get the best quality, and sometimes that involves choosing 256. also this is not a consistent problem I have saved many pngs with transparency at 256-colors, and not had a problem, although it has not been an uncommon problem for me to encounter...
...could someone dispel the mystery? Thanks!

Creating a Clone mask using an image |

Since the file itself is too large for attachment, I've included it as a Dropbox link below.
In the 'Base Terrain' layer, I need to use the clone tool to fill in the hexside slivers below the full hex depictions. The best way to do this would be to create a mask, that would only allow the clone to paste within the outlines of the hexside slivers. I initially thought that a floating selection could do that, since when I copy the original file into a new layer that does create outlines that do act as masks for the paintbrush tool, but of course, we can't do anything else with a floating selection until it's anchored, at which point the very outlines that I need disappear. Thoughts, suggestions?

Transparent Background Problem |
Posted by: Purplechris83 - 08-18-2020, 06:48 PM - Forum: General questions

Hi guys,
I'm new to this. I've been using the following method to cut a product out of a picture and make the background transparent:
Add Alpha Channel
Select Product image i want to keep using Free Select
Feather Image by 5,000 px
Invert
Clear
and this method has been working great until today where I have carried out the above method but when I put 5,000 px in Feather it won't accept it and keeps changing it to "50.00" px and then when I Invert and go to clear it makes the image a little transparent but I can still see the background. I have to keep pressing Clear 10 times until the image background is completely gone and then export but the image quality suffers and I'm wondering what I am doing wrong?
To try and fix this I have reinstalled GIMP twice (to a different directory the second time) and gone to Edit -> Preferences and Reset everything but I'm still having the same problem.
HELP! And thanks in advance.
