I understand that greater than 8 bits per channel the values will be much more than 0-255.

But I'm working with a program that is requesting RGB 0-255 values.  The problem for me is if I am in 8 bit precision, then it is a hassle to constantly convert 0-100% to 0-255.

Is there an option somewhere to change the display to 0-255 instead of 0-100?

Operating on osx. Problem getting desired effect

Desired Effect of a guassian blur:


Current result:

Closeup:


so It looks like the blur effect is a gradient opacity, but inverted? I want it to blur out from the border, not increase the opacity on the inside of the border. Border should be 100% opaque, with an increasingly transparent gradient out from the edge. 

What am I doing wrong?

• Given a source path (in blue)
  
• You provide an envelope path made of two strokes (in red)
  
• The script produces the bent path (in green)
  

   

• By design, the script only bends the path vertically (in the image above, you can observe that the vertical limits of the characters in the source and bent paths are aligned)
  
• The bent path is produced between the two strokes of the envelope path.
  
• The source path can be elsewhere,  it only needs to overlap vertically with the envelope strokes
  

Its based on some kind of mathematical function, right ?
Exponential growth ?

   

I have made a layer. I want to rotate it and duplicate then rotate it for the same amount of angle as in previous step.
Is there a shortcut for repeating these actions ?

Im trying to use my huion tablet. It recognizes it and i can configure it in setting but when i try to draw it makes a dot but i cant move the cursor once it made the dot. When i pull the pen off the tablet i can move the cursor again. This is very frustrating and ive tried everything on every forum post about this that I could find. Does anyone have any advice? I tried using previous versions of gimp.

How to make nova appear only with spokes and without gradient alpha? I like the gradient of nova in some cases but sometimes I would like only nova with spokes without that yellowish gradient in between spokes.

I've used GIMP for a couple of years, always interactive, but now I would like to resize a rather large number of TIF files to a standard format. I have two types of files, "fronts" (t???r???-???.tif) and "backs" (t???r???-???b.tif)

Manually, I would

• open the file
  
• change the only the canvas, to 2310 x 4842 pixels
  
• only for the "backs", add an "x" offset that is the difference between 2310 and the previous size
  
• click resize
  
• flatten the image
  
• export it with Deflate compression
  
• quit
  

I have some images with jagged edge; I made the background transparent and it was contrasting so I could leave little of the color fading in the result and the border not being gradual is obvious. I'd like to have the jagged edge smooth.

My first thought was anti-aliasing but I'm not sure GIMP have that and I wouldn't know what the best or most efficient way to go about with that. I did a search and the only relevant page I found was Fixing Jagged Image Edges with Gimp | Jafty Interactive Web Development, which I wonder if there's a better method.

Thank you kindly for your help
