Hello!

I have trouble with porting a script written in Script-Fu from Gimp2 to Gimp3. I managed to run the script, but when script execution finished, I've got the following error: argument 1 must be: number. Unfortunately, I cannot understand why this error occurs. Could anyone review my code and help me to make the script working. The script is below:

I've recently embarked on digitizing a number of b&w negatives, which I have scanned using VueScan. I'm now at the point of editing them slightly using Gimp (v 3.0), which has gone fairly well, after climbing the learning curve.

I now want to print them. To do so, I'm first selecting the Image-->Print Size, and selecting (for example) a width (7.0) and and height (4.692), which results in a PPI of 1303 in my case. From there, I'm simply selecting the "Print" option in Gimp and sending the job to the printer (Canon Pixma-100). In the Print dialog, the same sizes and ppi values are reflected (7 x 4.692, 1303). I'm using A3+ paper (I know, it's oversized, but it's what I have at the moment). I used to have the printer installed on a former computer, but that was years ago. This time around, rather than use the installation disks and their bloatware I merely downloaded the current printer driver from Canon's site.

When I print the photo at 300x300 dpi it prints very small on the paper (~3.5" x 2.25"). When I print at 600x600 dpi it seems to prints at the correct dimensions (~7" x 4.7"). When I print at 1200x1200 dpi it prints only a small portion of the image (very large), since the majority of the image would appear off of the page. In each case, it would seem that the image should actually print at 7.0" x 4.692" since that is what I selected...yet, these different sizes are the result. It appears that the DPI setting selected in the Gimp Print option is dictating the image size, rather than the Print Size that I have selected for the file.

I recognize that it might be the case that the printer driver is overriding the Print Size. When I select the printer via my Mac (System Settings-->Printers and Scanners-->Canon Pro 100 Series) there is no option anywhere to un/check a "Fit to Page" or "Scale to Fit" option, which I thought might be the issue.

Does anyone know how I can get images to print at the size I've selected, given my current setup?

Thanks in advance for any help or ideas, I appreciate it.

How do I combine this image with this video, so the green screen removed into and the image as the background instead
anyone know, I been trying and my brain still cant process it

I've recently had to reinstall GIMP on a fresh boot of my computer. When I important images that are larger than the canvas (i.e. I am working in layers and want to add something then resize) GIMP is automatically adding rows of dead pixels to the image. These images are seamless and do not have dead pixels/seams in the original. I have verified there are no additional pixels in the original image by opening it on its own, transforming it, and zooming in.

Does anyone know how to fix this? 

Thank you.

I've got several photos of items (lots of white with color images) that are taken with a backdrop.  I want to make the background transparent.  Initially I used a white backdrop which was marginal.  Then I switched to a light blue which wasn't much better.  Finally I changed to a dark Navy blue background and I figured the high contrast would be ideal.  Unfortunately I can't get rid of the background compleltely.
   My first attempt was with Fuzzy Select and when I clicked on the background it turned the entire image red.  Playing with all the settings (anti alias, draw mask, alpha channel) I just couldn't get it to work.  Never could get the Feather to activate.  So then I switched to Select by Color and that worked - mostly.  The problem is that the backdrop, which is a solid color, has some minor undulations which cause slight variations in color density.  The result is that some of these variations leave a shimmering effect which when saved aren't completely transparent.  There's still lots of contrast between the image and background so that baffles me.  I'm using Inkscape as the graphics editor and I'm a real amateur with Gimp so I could use come help.

Hi,

I've been using Gimp since 1996 for various purposes, but in recent years it's mostly for processing screenshots - capturing, combining, drawing arrows or text on them. In 2000 I bought Grokking the Gimp, and a lot of what was there still applies to the latest Gimp 2.

All was generally fine until a year ago, when I could no longer take screenshots because my Linux distribution moved to Wayland. I had the workaround of using a different tool and copying the result to Gimp.

With the move to Gimp 3, things got significantly worse. For one thing, now I also cannot scan images, because the xsane driver that worked with Gimp 2 is 8 years old and nobody maintains it (though there seem to be some workaround, but I didn't really need it, so I didn't check).

But the reason I'm writing this is that I cannot figure how to use the rectangular selection effectively. In the good old days, you could select a rectangle and copy it, and when you pasted it, you'd have a rectangle with whatever you copied on a temporary layer and that was that. Then you could move this temporary layer and change its opacity (which helped me align images) and then you'd choose to either transform the temporary layer into a new, real layer or "anchor" it to the leer below. Now when I paste it's not just my selection (because it's surrounded by transparency so the new layer is the exact size of the layer I copied from) and I need to keep switching between the Select and Move tools, because there is no longer a temporary layer. It also makes Fit Canvas to layers pretty pointless to me, as my layers are way too big (unless I use the crop tool, which I didn't need until now).

I couldn't find anything relevant in the manual or using the search engines and when I ask the AIs they either tell me that nothing changed regarding selection in Gimp 3, or that I must use the crop tool or other things that take more time than the equivalent Gimp 2 ways. Still, I can't imagine being the only one facing these issues, so I wonder if there is some guide describing the Gimp 3 equivalents of the basic Gimp 2 features.

Thank you!

If script-fu are placed in the "scripts" folder, they have a habitual and predictable behavior.

If I modify them and put them in "plugins" they have another one, changes must be added on purpose and sometimes you don't understand the mistake.

BUT if I put them in "plugins" Gimp 3.0 official appimage overcomes some problems that crash the script engine.

Now comes the problem, exactly like to be or not to be, I have to continue to use the "scripts" folder, or I have to arm myself and solve the problems it causes by moving them to "plugins".

I wouldn't want my "to be or not to be" to be Mel Brooks' film.

please share list of keyboard shortcuts for GIMP.

Last night I tried to install the bimp gimp plugin tool, but the make failed since a missing tool "gimptool" could not be found on my system. I also tried to see if the yast2 software tools could locate this tool, but to no success.

Now whenever I start up gimp, I hit a delay around 30 seconds or so then the following message appears:

gui_dbus_name_lost: the name "org.gimp.GIMP.UI" could not be acquired on the bus.

running gimp with the --verbose option shows:

INIT: gimp_initialize
INIT: gimp_real_initialize
gui_dbus_name_lost: the name "org.gimp.GIMP.UI" could not be acquired on the bus

And the about 20-30 sec delay is occurring here.

Since I have removed and reinstalled all the gimp software using the software manager, I don't believe that this problem is with the gimp software itself but lies somewhere else.

Is this the correct forum to ask this question? Or perhaps try a GNOME forum?

The 30 second delay is not tolerable, especially when I had over 24 gimp photos to redo just this morning.

Thanks for suggestions.
