Hard drive noises when performing operations |

I have gimp's tile cache size set to 5 GB (I have 8GB RAM, 1.75G in use). The temp and swap folders are set to a ramdisk. However, whenever I perform some function in gimp (say: moving a layer, filling a region, showing/hiding a layer), I hear what sounds like hard disk access.
How can I get GIMP to use my RAM which is more than sufficient for the size of images I edit, and not touch my disk except when saving and loading?

Cloning colors (newbie question) |

Hi. I've been using the GIMP 2.8 for a while now for presentation materials, but that has generally involved repeating the same 4 - 5 tasks, so I don't really know the full range of options.
I have a series of photos I have been working on, and some of them were taken with an older camera. These photos seem to have a warmer and deeper color to them than the new ones. I've tried to recapture it by adjusting the camera settings but that does not yield any good results. I was wondering if there is any way of cloning the colors from the older photos to the newer ones, or other way of using the older photo as a template/base for new ones?

Script-FU: Batch rotate script |

I am trying to write a batch rotate script, to rotate a number of images by an angle which is passed to the script.
I have the following, which is successfully registered in Gimp:
Code:
(script-fu-register
"script-fu-batch_arbitrary_rotate"
"Batch Rotation"
""
""
""
""
"*"
)
(script-fu-menu-register "script-fu-batch_arbitrary_rotate" "<Image>/Tools/My scripts")
(
define (script-fu-batch_arbitrary_rotate pattern inDegrees)
(let*
(
(filelist (cadr (file-glob pattern 1)))
)
(while
(not (null? filelist))
(let*
(
(filename (car filelist))
(image (car (gimp-file-load RUN-NONINTERACTIVE filename filename)))
(radians ( / (* inDegrees 4 (atan 1.0)) 180)) ;converts angle <inDegrees> to radians
(gimp-item-transform-rotate image radians FALSE 150 150)
(drawable (car (gimp-image-get-active-layer image)))
(gimp-file-save RUN-NONINTERACTIVE image drawable filename filename)
)
(set! filelist (cdr filelist))
)
)
)
)
This is called in terminal by (to rotate each image by 35 degrees and save):
Code:
gimp -i -b '(script-fu-batch_arbitrary_rotate "*.png" 35)' -b '(gimp-quit 0)'
The terminal output states: "batch command executed successfully", but the images are not rotated. The files' properties suggest that no operations were performed.
I have racked my brains over this; can anyone help with the above script?

Add new paint method ? |

Is there a way (short of C code and recompiling GIMP) to add a custom paint-method?
I'd like to add a new painter to the list (gimp-context-list-paint-methods)
So that (gimp-drawable-edit-stroke-selection drawable) will do a custom procedural edit to the pixels.

Hello there. I have a problem that tortures me 2 days now.
I want to extend the colormap at indexed pictures by one color with script fu.
;get colormap length from header
(set! colormap_length (car (gimp-image-get-colormap image)))
;get colormap data from tail
(set! colormap (car (cdr (gimp-image-get-colormap image))))
;extend header
(set! colormap_length (+ colormap_length 3)) ;increaze by 3 bytes/1 color
;extend tail
;here, i want to make colormap:=colormap+"000000" thus extend the list
;set new colormap
(gimp-image-set-colormap image colormap_length colormap)
(Variables are defined ok)
I tried almost everythink while playing with let, set, list, cons car etc etc.
Thank you.

Hi, I tried to insert my avatar with dimensions smaller than 100x100 and less than 25Kb.
A message tells me that it has been accepted. Bat I do not see it on the forum near my nick name.

problem with set color to alpha |

New to all of this, Perhaps I am trying to go about this the wrong way.....not sure.
But, for instance, suppose I wanted to cut an image of somebody out of picture "A", and insert it into an already existing image "B"
SO, I painstakingly draw a white area all around the perimeter of the desired target image, then extend that white area sufficiently large that I can select and crop to a rectangular image for use.
Then I review the image and find a color not in use in the target image, say HTML color h1cf905 for example ....no sign of that color anywhere in the target image , and then change the white area surrounding the target to that color, and then set that color to alpha.
Hoping to paste that image, complete with the transparent surround, into the "B" image.
Except when I set the surround color to alpha, it's causing the colors in the target image to get all whacked out. For instance with the color mentioned set to alpha, everything is shifting into violet colors.
Almost seems like the "color to alpha" function isn't discriminating properly, and is perhaps shifting all greens to alpha?
Thanks in advance for pointing me in the right direction

Radius color to transparency overlay |

I'm trying to create a sort of overhead circular glow effect. Imagine looking down on a lamp from overhead and seeing a yellow or white glow that falls off with distance. I would like to lay this over an existing image of a map. I would the effect to be transparent Strongly colorizing the map at the center of the effect and falling off toward the edge of the effect like a radiant gradient. I'm far from a GIMP expert.
