[Gimp-user] How I´ve losed a image.
Hi all! Linux Debian unstable + The GIMP 2.6.5 editing an image of about 4000x3000 pixels creating and destroying layers trying to find the best sets for a effect. At one point the OS was become unresponsive and at the bottom bar of GIMP, the displayed size showed more than 1,4GB. Then I´ve typed CTRL+S to save and after waiting about 15 minutes I´ve pressed the reset button. After restarting, the file had 0 size. I had to recover it from a backup, losing all the work I did and saved in the file previously in the morning.(*) The questions are: How can I control the memory usage of The GIMP? I supose that tweaking the different settings in environmet prefences, but I am not sure how to count it, should I sum max mem for undo to max mem for cache in order to get the maximum of memory I am allowing to The GIMP? Are there other settings affecting the memory usage? Will a feature request of "indirect saving" be taked in account?, Say save to a newtmp file, then copy/move the main file to oldtmp file, then move newtmp file to main file then remove oldtmp file. This should ensure that a system crash in the middle of a save operation will be recoverable. And finally, will a feature request of auto-backup be taked in account? (*) This is not exactly true, as I´ve said, I was trying and _discarding_ settings and procedures to get a desired effect, so after recovering the file from the backup I was able to get the final result in about 30 minutes of work :) Yours Pere ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

You can try this: starting from the drawed image: redo all up to have all dots drawed. select all. copy paste as new image undo up to pristine state before drawing dots but after the enhancements. select all (you will not be able anymore to redo) copy in the new image: duplicate the layer (as this you have a backup of the dots) hide the duplicate add a new layer import the pristine state into it -> paste duplicate it and hide the duplicate (you will need later) raise the visible drawed layer to top. set mode in the drawed layer to divide if the dots are not white or black. else to grain extract. flat visible layers.

Yes, I currently save as xcf. However, the editing of transparent pixels is handled by a script (mktpstamp) as the end step to save a png from a layer in the xcf file, and sometimes I want to improve the results of this script, hence I am editing directly the png file. I've tried a call to file-png-set-defaults in the script I use, but even if I see ~/gimp-2.4/parasiterc writed when quitting gimp, this doesn't affect the current session.

Select by fuzzy select or by color black with threshold 50 grow the selection by the number of pixels needed to cover the dark ones.(1 or 2) CTRL X to delete all the selection. You get a image that lacks the edge pixels, they will be regenerated from the current edges when running the script.

Hi all! I usually have to scale down some images, so I ask about the best practice to do so. The images (RGB photografies) are in the range of 1000x1000 - 3000x3000px and have to be scaled to a range about 200x200 - 400x400px. I've read something about go scaling 50% in steps approaching the desired final size and after that scale to the final size. Is this needed in gimp 2.4rc* or the internals of scale does yet this? I've read too about oversharp the image before scaling down: http://www.robertmekis.com/articles/sharpening/mekis0ta001a1a.html There is a script that claims to do this, http://registry.gimp.org/plugin?id=6929 but I guess that the calls it does to (gimp-selection-sharpen img) does not meet the SHARPEN or SHARPEN MORE from photoshop, so what are the gimp equivalents for SHARPEN or SHARPEN MORE? I've had problems in the past (gimp 2.3.13) with lanczos alghorithm, after that I've changed the default interpolation to cubic. It is time to give another chance to lanczos? Any other hints for scaling down are apreciated. Thanks Pere ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

(and very powerfull BTW, you can change the default saving directory on the fly): open a/b/c.xcf (named file) new unnamed.xcf new unnamed1.xcf save unnamed.xcf to d/e/f.xcf (file-chooser comes up) default saving directory comes d/e save a/b/c.xcf ( CTRL+S file-chooser doe not appear as the file has yet a name) default saving directory comes a/b nearly without notice save unnamed1.xcf What happens? a/b is presented when I just manualy selected d/e in the previous opened file-chooser. What about this?: If an image already has a filename associated to it, then open the Save file-chooser in that folder. Otherwise use the folder of the most recent save operation that implies the use of file-chooser.

No, dir bookmarks not solve any problem, but can come in help when the gimp assumption about the directory where to save a file and the user wanted directory differs. There are two issues here: Find good default saving assumptions for most users. What to do when a user has different needs. Bookmarking recent saving dirs deals with the second case. > Perhaps we need to collect the typical usage scenarios that involve use > of the file-chooser and evaluate how the current solution deals with > them and if there are ways to improve it. I just have a suggestion for "paste as new" and is that the default saving directory for the new image can inherit the default saving directory from the image where the action is called, or if it is called from the toolbox, inherite from the active image. As this, the users can have some control over the default saving directory.

May be Gimp can auto add/remove Bookmarks? I guess this can give more problems than adressed.

[Gimp-user] Clicking on certain parts of the image window does not active it.
Hi all! Start gimp, display the layers dialog and open two diferent files or create and draw something on one of them. In the toolbox go to file -> preferences -->Window management and uncheck "Activate the focused image" click on OK Now click on a window image in the middle, layers dialog thumbnails updates to that image. Now click on the scrollbar or quick mask or the zoom botton or the units botton of the other image, layers dialog does not update. If instead you click on menubar, main image, helper rules, state... the image is activated. Is this the expected behaviour? If yes, can someone explain what are the advantages? I understand that when you have a window manager configured to "focus follow mouse", maybe you don't want an image get activated by accident just by passing the mouse over, but why the need to click on specific parts of the window to activate the image?

After some try/error and a look at the code, it seems not. SF-Filename uses gtk_file_chooser_button, and acording to http://library.gnome.org/devel/gtk/2.10/GtkFileChooserButton.html#id3631060 gtk_file_chooser_button only supports the GtkFileChooserActions GTK_FILE_CHOOSER_ACTION_OPEN and GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER, not the GTK_FILE_CHOOSER_ACTION_SAVE GTK_FILE_CHOOSER_ACTION_OPEN Indicates open mode. The file chooser will only let the user pick an existing file. GTK_FILE_CHOOSER_ACTION_SAVE Indicates save mode. The file chooser will let the user pick an existing file, or type in a new filename. So, if someone like I wants to write a nonexistent file, and this file has to be selected by the user, the obvious solution is to use SF-DIRNAME to get the directory and follow a SF-STRING to get the filename. After that, a (string-append dirname "/" filename) in the code gives the full path.

[Gimp-user] Script-fu SF-FILENAME don't show the default setting
Hi all! When using SF-FILENAME, if the file exist, the name of the file is shown in the button, but if the file does not exist, ie. has to be created, there is "(none)" in the button. Can someone else reproduce? Is there a way to show the name on the button even if the file does not exist? To test install and run the script below, if you click on "OK" without selecting a file, the string "nonexistentfile" is shown as a message. If you select a existent file via the file selector, the name of the file is show on the button and when click on "OK" the full path is shown. (the desired behaviour) If you select a non existent file via file selector (say type the desired name on "Location:" and press "Open"), "(none)" is shown on the button, confusing as one can imagine that the selection has failed, but when click on "OK" the full path is shown as desired. The test script: (define ( script-fu-test-filename filename) (gimp-message (string-append "Filename: " filename))) ( script-fu-register "script-fu-test-filename" "/Script-Fu/Test/testfilename" "Test for SF-FILENAME" "" "" "" "" SF-FILENAME "Filename" "nonexistentfile" ) Gimp 2.4 RC1 linux Debian unstable Thanks Pere ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Is set!/define the only difference with the new script > engine? I edited a few more and all seems well. > I am not sure, I am just learning. The main difference is the interpreter Tinyscheme vs SIOD, each one has its own interpretation of the standard. About set!, it serves to put a value to a variable, not to declare it. Say open a gimp script-fu console and type the following: (set! x 1) ---> Error: set!: unbound variable: x (define x) ---> x (set! x 1) ---> 1 As you see, set! works once the variable is declared.

[Gimp-user] Some questions about script-fu and tinyscheme.
Hi! The first is about writing text to a file. In SIOD doing something like this I can write text to a file: (let* ( (txt-output-file-name (string-append base-filename ".txt")) (txt-output-file (fopen txt-output-file-name "w"))) (fwrite (string-append text-string "\n")txt-output-file) (fclose txt-output-file)) If I try the same in tinyscheme it raises an error. How can I do the same in tinyscheme? For now, I've worked around as this, but looks ugly: (begin (define text-filename (string-append base-filename ".txt")) (define txt-output-file (open-output-file text-filename)) (for-each (lambda (z)(write-char z txt-output-file ))(string->list text-string)) (newline txt-output-file)) The second question is about the memory used by gimp-image-undo-group start->end. If I use this, my script easy eats all the memory. (It creates, moves and destroys 49 layers per an undetermined number of runs) I've created a simple script to test and show: http://fornol.no-ip.org/linux/gimp/group-undo-test.scm Defaults to create and destroy 20 layers x 5 runs = 100 layers and group-undo each run. Create a new blank image (420x300 pixels) run the script on it script-fu-->test-->group-undo If you check group-undo you will get an image about 193MB If you don't check, the image will use 64.2MB Well, I have setted 64MB as max undo memory, but why this set is not used when grouping undo?
