There are quite a few details as to how GIMP is behaving on my computer, so skip to the TL:DR if you want a summary.

I'm currently using GIMP 2.8.22 on a windows 8.1 64-bit installation on my laptop with a Turcom 8" x 6" tablet connected. The primary issue is with drawing; I cannot draw in GIMP with the pen tablet. I can draw with the mouse, but when I put the pen on the tablet, I can only place a dot. Moving the pen around still moves around the cursor, but it doesn't actually draw. If I drag the cursor to one of the toolbox areas of the screen while holding the tablet down (like drawing), it draws a straight line from where I started to where the cursor ended on the toolbox section (I use single window mode). It seems to pick up on the pressure with which I jab the tablet with (I can place light or dark dots), but obviously I want to do more than just place dots. I have already gone into the input configuration windows and set the tablet to use the "screen" and all of the features of the pen are configured in the driver. The pen works in the other software I use, but not in GIMP. I tried GIMP 2.6.8, and it just worked right after installation; I didn't need to change anything. Am I missing something?

As for the movement issues, it seems that nearly every movement command that is issued by not directly clicking on the scroll bar (Middle click to pan, scroll wheel, and zooming with ctrl) do not work until some amount of time has passed with the drawing window being active (about 5 seconds?) or until one of the scroll bars has been clicked. Because middle clicking is the only way I would move around when using the pen tablet, this is a must-have feature that needs to work reliably.

I feel like both of these issues are being caused by some weird active window shenanigans, but that's about as much as I can think of. It just doesn't work.

GIMP version: 2.8.22
Operating system: Windows 8.1 64-bit
Pen Tablet: Turcom TS-6608N
Computer: Lenovo Y500 Laptop

TL;DR: I have set up the drawing tablet to work in GIMP, but it only places dots and cannot make strokes. The mouse can. In addition, the keyboard and mouse driven movement controls (pan, scroll, zoom) don't work until I have physically clicked on the scroll bar.

I'm using the grid feature for the first time and I find the grid and ruler do not match up.
e.g. I create a new canvas 12cm by 12cm, then set the grid spacing to 5mm in both directions. The ruler shows the canvas to be the correct size, but the grid doesn't line up with the 5mm spacing. It prints incorrectly too. It's the same if I use inch measurements.
Is this a known problem or am I doing something wrong?

I've recently updated my version of Gimp, from a very old version, and there is something new that is costing me a lot of time. I'm working with tile based graphics, so defaulted to a grid, and when I copy and paste an image to move it, the boundaries of the pasted image auto shrinks to meet the boundaries of the graphic (ignoring the transparent background, and previously set selection tool size).

This; (upon cutting)


Becomes this; (upon pasting)


Instead of this; (upon pasting)


I'm wondering if there is someway to make it show me the boundaries of the new layer upon pasting (Floating Selection(Pasted Layer #1) it for quick left click merging to my current active layer.

Any help would be very much appreciated. At present I have to draw a mark in a corner of my grid that meets two sides of the grid in order to line up anything I move that doesn't go to the edge of the grid. This ends up costing me double the amount of time, if not more, than simply copy and pasting while retaining the dimensions of the rectangle selection tool for the pasted image.

HI, I would like to create joints on a standard image of wood, to obtain imitation wood tiles, how can i do? Thanks

Basically, the BIMP has been a handy little tool for me to alter lots of photos quickly. However, curves is not one of the offered features. When looking around, I came across this user-made script  and tried to make it work. I don't totally understand the instructions, have gimp located both on my c and f drive (exe on F, brushes etc on C) & am using 2.8, so whether it's due to my own lack of abilities or something else, I haven't been able to make it work. I was thinking that the script could be incorporated into BIMP. When I loaded it into BIMP, it seemed to work fine and I could enter in the name of the curve file I had saved and wanted to use. Then the error message "Calling error for procedure 'script-fu-kp24-read-curves': Error: (: 1)peek-char: argument 1 must be: input port" popped up. Any ideas?

I am trying to position a dialogbox relative to the main GIMP window (using Python-fu)

1. I load a file in GIMP as follows

first_file = os.path.join(PathToProcess, filename)
img = pdb.gimp_file_load(first_file,first_file)

2. I try to get the position of the file as follows

wdw = gtk.Window(gtk.WINDOW_TOPLEVEL)
xm,ym = wdw.get_position()

xm, ym returns as 0,0. 

I have tried different ways to reference the main GIMP window, but it does not seem to work. 
How should I get the position of the main GIMP window (with my file opened) on the desktop ?

When I bring in a photo 1600w by 2500h, gimp creates a window that is of these dinensions, but the photo is much smaller within the window, surrounded by white borders. Cropping leaves me with a photo of too few pixels. I want the photo to fill the allocated window. 

I always use only open-source editing programs. GIMP is an incredible photo editor, I'm using it with RawTherapie and Luminance HDR

My photos on 500px processed in GIMP are here.

Best regards and again - thanks for help and support!

I am running gimp 2.28 on Fedora 26 (kernel 4.13.5-200). I installed gimp through the dnf package manager. The installation included libopenraw-0.1.2-1 as a dependency. However, I cannot open PEF raw files from my Pentax camera. The gimp open dialog does not even see the .pef files. 

I can install the ufraw-gimp package and open the files. However, the ufraw interface actually gets in the way of some things I want to do. What makes this more curious for me, I was able to open the PEF files without installing ufraw-gimp on one or more previous versions of Fedora. Unfortunately, I did not record the details of the previous version because I didn't know I would need them.

I can open the PEF files in darktable and gwenview, but I assume they use different libraries. I see libraw1394 and LibRaw in my rpm listing. 

Is this a known problem? What can I do to troubleshoot the problem? I am willing to build from source for troubleshooting. Eventually, I would like to get back packages for convenience and consistency. 

Thanks!

I have custom images created, and I wanted to know how to create a straight line across. I would also like to know how to put one image on the bottom line and another on the top, kinda like a border. If there is a way, I would like to have 2 lines creating a X and having 4 pictures on each side.
Thank you for the help!
