I have an xcf project which is so large that when it exports to tiff it fails due to reaching the tiff file limit size. This is due to the 32bit tiff file size limit. I would like to be able to export my image to BigTiff, the 64bit tiff file type. Currently, I am able to work around this by cropping the file into pieces, saving them each as 32bit tiff files, and then using ImageMagick to append the files into a TIFF64 BigTiff output file.

How do I get GIMP to export as TIFF64?

Thanks

Hi

I need to edit an xray. I have created a shape from one section of the image which i can move around. I have moved the selection shape to another part of the x ray. I want to fill this selection shape with the colour/gradient of the image behind that it sits atop. How do i do this? (Mac OSX)

I've added an attachment of where i am at the moment.

Thanks!

Just found this, and it is awesome.

It makes it very easy to make seamless patterns or tiles.  I just create an image 3x3 times the tile size, using a grid as a guide.

Word of caution: there are no circular images. There are images where corners are transparent, so that only a circle shows.

First make sure that your layer has an "alpha channel" (menu: Layer/Transparency/Add alpha channel)(if it's grayed out, it means you already have one)

Then create a circular selection ("Ellipse select tool", the 2nd one in the toolbox). You can check the "Tool options" dialog: menu: Windows/Dockable dialogs/Tool options (top of list). If you want a true circle, check the "Fixed" option, select "Aspect ratio' and enter "1:1". Depending on what kind of marks you have, you can use the diagonal framing (default) where you click one corner, and release at the opposite diagonal corner, or the radial one (check "Expand from center" in the Tool options) where you click where you want the center of the circle and release where you want the border.

Once the selection is done, you can move it (click around the middle) or extend it (click inside, but close to the sides).

One you are have the required selection, invert the selection, so that everything is selected, except your circle: menu: Select/Invert (or Ctrl-I)

Erase the selection (menu: Edit/clear or "Delete" key). You should have your central circle left, surrounded by a checkerboard pattern.

Reduce the checkerboard to the minimum by auto-cropping the image (menu: image/autocrop image)

Export the image in a format that supports transparency, like PNG. JPEG doesn't support transparent images...

If you are going to work further on the picture, save it as XCF (Gimp native format).

I have a photo and would like to crop it into a circle and delete what's outside the circle.  How do I do this?  Thank you........

I've been making some changes to a duplicate of the default Dark theme provided by GIMP 2.9.7 via the 'gtkrc' file to suit my requirements.

Most of the UI seem fine now, but I can't find the right modifier to change the font color of the inactive options in the Menu bar (it doesn't go well with the dark theme).

However when I change the values of 'text[NORMAL]' of 'gimp-dark-list-header-style' in gtkrc from empty to any two digit hexadecimal value, the color of the menu font (active options included) and docked panels changes to white.


From the gtkrc file:

style "gimp-dark-list-header-style"

{
  #Comment out the ythickness setting below for thicker column headers.
  #ythickness = 0

  GtkTreeView::odd_row_color = "#828282"
  GtkTreeView::even_row_color = "#828282"

  #
  # set custom header text color here
  #

  #fg[NORMAL] = "#00F"
  #fg[PRELIGHT] = "#00F"
  #fg[SELECTED] = "#00F"
  #fg[INSENSITIVE] = "#00F"
  #fg[ACTIVE] = "#00F"

  #
  # set custom text color here
  #

  text[NORMAL] = "#"
  #text[PRELIGHT] = "#FF0"
  #text[SELECTED] = "#FF0"
  #text[INSENSITIVE] = "#FF0"
  #text[ACTIVE] = "#FF0"


   


Any value above 2 digits reverts it to the default color.



How will I be able to solve this?

Thank you beforehand for any help.  

GF.n was a bit behind, software-updates-wise (like 13 successive kernel updates, 106 packages, 3 months, shame, shame, ). So:

Hello,

I installed gimp one week ago and used python-fu for scripting. It works very well on windows-10

Yesterday, i installed gmic. It seem to work well on GUI.


Now, here comes the issue:
After having installed GMIC the python-fu script does not work anymore. I have this error message:


GIMP-Error: Unable to run plug-in "zlib1.dll"
(C:\Users\admin\.gimp-2.8\plug-ins\gmic_gimp_qt\zlib1.dll)
Failed to execute child process (Exec format error)


When i delete the gmic_gimp_qt directory completely the script work again.

Thank you for you help.
My goal is to automate the script diego's pseudohdreffect http://gimpscripts.com/2016/10/pseudo-hdr-effect/ on windows 10 using python-fu

Hi there, 

I'm looking to create educational videos for my clients similar to the Khan Academy videos (e.g. https://youtu.be/XSb3N4CM3yY).  I'm using a Wacom Intuos pen/tablet but my results are not quite as neat as in the video.  I was wondering, could you suggest what GIMP toolbox - tool options might be similar to what the author is using?

If you're able to comment on the tool type, the brush type, size, dynamics, etc that would be greatly appreciated.

I have had Gimp 2.8.22 for some time now without major problems but lately I notice the two tool docks hang up for about 15-30 seconds after closing the large image window.  I tried the single window mode and now I cannot get back to the multi window mode.  I have the image window, and the two tool docks are together as one.  I have not been able to break them apart.

I wonder if this has something to do with the large windows updates that I get every once in awhile.  I had one not long before this trouble with Gimp.  I use Windows 10.

Has anyone had trouble or know what to do about it?
