** Description changed: + (02:12:36) ideasman_42: stani, did you write phatch ? + (02:15:47) stani: ideasman_42: yes, I am actually writing it (02:16:14) ideasman_42: stani, ah, my dad was using it for a bit, but we had some trouble with the brightness contrast (02:16:35) ideasman_42: hes making a book and needed to make a whole lot of gray scans more contrasting (02:17:06) stani: ideasman_42: did autocontrast work? (02:17:19) ideasman_42: the problem was there seemed to be no way to make gray tones black without 100% contrast (02:17:36) ideasman_42: didnt try but wanted all the scans to have the same color adjustment (02:18:25) ideasman_42: stani, we did a lot of trial and error on this (02:18:45) ideasman_42: and Im fairly sure the way it does contrast is odd or at least different to most other apps (02:18:53) ideasman_42: stani, what would be awesome would be simple levels (02:19:22) ideasman_42: since we only wanted to make the greys black and leave the white alone (02:25:06) stani: ideasman_42, send me such a picture or give a download link, i like real world test cases (02:25:09) ideasman_42: stani, http://www.graphicall.org/ftp/ideasman42/LDB_02.png , wanted something like this http://www.graphicall.org/ftp/ideasman42/LDB_02_edit.png (02:25:16) stani: ok (02:26:00) ideasman_42: but in a pradictable way- the problem with auto is if you apply to every picture, a small black pixel can throw it off (02:26:57) stani: ideasman_42: would you mind if i attach these images to a bug report? (02:27:08) ideasman_42: stani, np (02:27:12) stani: ideasman_42, as your fathers contact details are on it (02:27:21) ideasman_42: nah its ifne (02:27:23) ideasman_42: fine* (02:27:33) ideasman_42: the books online anyway (02:28:10) ideasman_42: stani, had to use xnview instead, good ol Motif interface :S (02:29:44) stani: which command in xnview? (02:30:23) ideasman_42: contrast of 20 and "Change Gammut" of 0.5 (02:30:56) stani: that should be in imagemagick (02:31:09) mp3man4: ideasman_42: does the documentation update reflect the status in python in most recent graphical builds? or is it being updated and changed? (02:31:25) ideasman_42: stani, still, what do you think about levels in phatch, not as some external option? (02:32:03) stani: ideasman_42: i think it is fine, but what do you mean as an external option? (02:32:21) ideasman_42: stani, I meant as a built in filter thats easy to access (02:32:23) ideasman_42: hey papo (02:32:45) ideasman_42: like contrast is now, if internally it uses some other method then thats fine (02:33:09) ideasman_42: could be 2 sliders, black levels and white levels if you didnt want to make an interface like the gimp
