[Gimp-user] darkening a grey-scale drawing
I have a simple line drawing that is in shades of light grey against a white ground. My aim is to increase the grey scale range from 000 199 to 000 to 255. Grokking the Gimp suggests I should use the Threshold Tool, but this produces unsatisfactory results. By moving the sliders I can darken the light grey to black, but what I'm left with is just what had been the original very darkest greys, and the lighter greys disappear. Am I just being clumbsy, or is there a better approach? -- Haines Brown KB1GRM ET1(SS) U.S.S.

[Gimp-user] Does Gimp have CHOP like ImageMagick
SuSE 8.2, 9.3 Gimp 1.2.3, 2.2.4 Does Gimp have a CHOP tool similar to ImageMagick? Magick CHOP chops a vertical or horizontal bar from an image.

Re: [Gimp-user] Does Gimp have CHOP like ImageMagick
Carol, A single mouse drag defines the slice. The slice disappears and the image strips above and below or left and right of the slice join together as one image. An example of use: we photograph visiting groups against a white wall with a sign several feet above their heads. A Magick vertical chop drops the sign to about one foot above their heads. Without carefully examining the mortar joints in the wall I can't see the chop.

[Gimp-user] David's Batch Processor
After a long break, I've put a new version of DBP up on my site at: http://members.ozemail.com.au/~hodsond/dbp.html Source only at this stage, no Windows binary available. DBP is a batch processing plugin for the Gimp, that performs a number of common operations (rotate, blur, colour correct, resize, crop, sharpen, rename, move, and save in new file format) on a collection of images. It is all gui-driven, no scripting, and the operations can be previewed on a single image before applying them to the whole batch. This version (1.1.2) fixes a few problems with the Sharpen control, adds Saturation to the colour correction page, and might fix a bug that appeared on 64 bit systems. -- David Hodson -- this night wounds time ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

My aim is to increase the grey scale range from 000 199 to 000 to 255.More specifically use levels and slide the left hand and right hand sliders in towards where your histogram starts. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
