[Gimp-user] Script-Fu Illegal Function Error
I am getting an “Illegal Function” error message for a Script-Fu script I wrote. Can anyone tell me what I am doing wrong? The script is supposed to make a selection from the active path (vector), fill the selection with the foreground color and stroke the selection with the active brush. I have run the entire script and the “define” part through the Script-Fu console with out any errors. The individual commands also work when I enter them in the console. I am running Gimp 2.6.8 with an Ubuntu 10.4 operating system. The script also shows an illegal function with Windows7. Here is the script: (define (script-fu-colorline image drawable) (let* ((MyVector (car ((gimp-image-get-active-vectors image) (gimp-image-undo-group-start image) ;This clears the active layer (gimp-edit-clear drawable) (gimp-vectors-to-selection MyVector CHANNEL-OP-REPLACE TRUE FALSE 5 5) (gimp-edit-fill drawable FOREGROUND-FILL) (gimp-edit-stroke drawable) (gimp-selection-none image) (gimp-image-undo-group-end image) (gimp-displays-flush) ) ) (script-fu-register script-fu-colorline Colorline Color as path Harlan Boise (c) Harlan Boise October 16, 2010 RGB* GRAY* SF-IMAGEMyImage 0 SF-DRAWABLE MyDrawable 0 ) (script-fu-menu-register script-fu-colorline Image/Script-Fu/Tutorials) Can anyone help? -- Aitchbee (via gimpusers.com) ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

[Gimp-user] Script-fu script defaults
Hello people. A couple of years ago, I wrote a script to add titles to images. I offer the options of position, color and combination mode in the dialog. I use this script quite often. I never found if it is possible to assign default values to the variables, eg. set the color dialog by default to gray 25%, or set a dropdown selection to a particular value. (I know, in this case I could simply change the order of the items, but still...) If this is documented somewhere, I'd appreciate a pointer.

Re: [Gimp-user] script-fu: saving dialog choices
Quoting Alan Campbell gimp-u...@alancampbelllists.ukfsn.org: That's really an abuse of the gimprc though. So it's really only meant for GIMP and GIMP plugin settings? I agree with Sven that using gimprc for this purpose is inappropriate. Also it looks like once I've called gimp-gimprc-set, no way to remove expunge evil deed from the gimprc file? Correct. it would be quite a task to remove your script-generated settings from the gimprc while retaining the user's configuration choices (as well as the script-generated settings of other scripts, assuming they likewise employed gimprc). In addition, storing script data in gimprc would somewhat break the documentation for gimprc. While a few scripts adding settings to gimprc would be acceptable (which is why those PDB functions are exposed), if this became convention then gimprc might soon become cluttered with undocumented settings. But the worst aspect of scripts saving data in gimprc is that the gimp-gimprc-set function interacts with the file every time it is invoked (whereas the parasiterc file is only rewritten upon GIMP exit). It is not really a good idea to have a script reading, parsing, and writing back a file each time it is executed -- doing so makes your script dependent upon file system speeds (it is also conceivable in theory that your script will be iteratively executed hundreds of times in rapid succession). It is far better conceptually to manipulate such data in memory, and saving the data only upon exit. It would be much better to get the parasites problem fixed. Sure. I'm not in no hurry. Lots more wrok to do on my woodrat scripts. Any guess re timescale? Keep in mind that even should the bug be fixed today, if you are sharing your script with others then you will want it to work with versions of GIMP which are in current use. Thus I would recommend using the work-around previously provided (if your script isn't intended for general distribution, you needn't worry about this). It would probably be a year or two before you could reasonably expect that most users would have updated to a fixed version. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Re: [Gimp-user] script-fu: saving dialog choices
Hi Saul, Many thanks for instant help. I'm trying to figure ut if there's any way that choices made by user in dialog widgets can be remembered and used as values of those widgets next time dialog runs. That is precisely how script dialogs currently behave; the last used values are presented. These last values will be reset to their original default values if 1) Script-fu is refreshed (Filters-Script-fu-Refresh Scripts) or 2) GIMP is restarted. Sorry, I mis-stated my problem. I'd like dialog to come up with same widget values next time GIMP is started up. ...(snip)... Tick quoting does not result in evaluation of the list elements. Use 'list' so that WRF_BIT_WIDTH gets evaluated and replaced by its numeric value: Thanks, I think it I read that bit in the Scheme manual and forgot it. ...(snip)... If, however, the issue you are attempting to address is having the last values retained across sessions (or survive a Script Refresh), this would be possible by storing your script's last values in the gimpdir/parasiterc file: (define (script-fu-woodrat image drawable bit-width) ; Substitute function owing to buggy parasite-attach behavior (define (fu-parasite-attach parasite) (gimp-parasite-attach parasite) (while (not (string=? (caddr parasite) (caddar (gimp-parasite-find (car parasite) (gimp-parasite-attach parasite))) ; Save the user-specified bit-width to an application parasite (fu-parasite-attach (list WRF_BIT_WIDTH 1 (number-string bit- width))) ... ) (script-fu-register script-fu-woodrat : : : SF-IMAGE ... SF-DRAWABLE ... SF-VALUE Bit width (catch 17 ; fallback value if first-time run (string-number (caddar (gimp-parasite-find WRF_BIT_WIDTH))) ) Note that 'gimp-parasite-find' is only executed once: when GIMP is initially loaded (or if scripts are refreshed). Even though the parasite is saved every time the script is executed, it is actually GIMP's internally stored last value (not the parasite) that is used in determining the value for the 'bit-width' parameter. The only reason you'd want to take these steps is to support last values across different sessions. The behavior you desired (as expressed in the first paragraph of your post) is already supported by GIMP. Sorry, mis-stated by requirement. parasites are just what I need. Can't find much about them. (list WRF_BIT_WIDTH 1 (number-string bit-width))) First list member: parasite ID string. What's the second list member? Flags, I understand from one search result I found. Used? Third list member: parasite value (must always be a string). So an RGB colour value would have to be stringified. unstrbreakup maybe?

To my knowledge, the FLAGS parameter controls 1) whether the parasite is persistent across sessions, and 2) whether adding the parasite is an UNDOable operation. 1) is controlled by the least significant bit of FLAGS, while 2) is controlled by the second bit.

[Gimp-user] script-fu: saving dialog choices
Hi, I'm trying to figure ut if there's any way that choices made by a user in dialog widgets can be remembered and used as values of those widgets next time dialog runs. In most other scripting languages I'd save choices to somethng like an ini file, and retrieve stored ini file values before displaying dialog. Hmm. Ok, a few problems: (a) How to run code before dialog displays. I tried this at top level (i.e. not enclosed within any procedure: (load F:\\test.scm) where test.scm contained (define WRF_BIT_WIDTH_SETTINGS '(17 0 256 0.1 1 1 1)) ; and script-fu-register dialog def included SF-ADJUSTMENT bit width: WRF_BIT_WIDTH_SETTINGS That seemed to work.

Re: [Gimp-user] script-fu: saving dialog choices
Quoting Alan Campbell gimp-u...@alancampbelllists.ukfsn.org: Hi, I'm trying to figure ut if there's any way that choices made by a user in dialog widgets can be remembered and used as values of those widgets next time dialog runs. That is precisely how script dialogs currently behave; the last used values are presented. These last values will be reset to their original default values if 1) Script-fu is refreshed (Filters-Script-fu-Refresh Scripts) or 2) GIMP is restarted. BUT: if loaded scm contains (define WRF_BIT_WIDTH 17) and script-fu-register dialog def includes: SF-ADJUSTMENT bit width: '(WRF_BIT_WIDTH 0 256 0.1 1 1 1) the value of WRF_BIT_WIDTH loaeded from test.scm doesn't seem to take. Tick quoting does not result in evaluation of the list elements. Use 'list' so that WRF_BIT_WIDTH gets evaluated and replaced by its numeric value: SF-ADJUSTMENT bit width: (list WRF_BIT_WIDTH 0 256 0.1 1 1 1) Another approach I tried was to begin declaration of dialog (script-fu-register WRF_DIALOG_FUNCTION (wrf_test_text) ;menu label : : which also seemed to work; in principle I could write code for (wrf_test_text) that interrogated an ini file, retrieved values, constructed correct lists, initialised variables used in later parameters of script-fu-register. Rather round-the-houses, but works. Keep in mind that the arguments of 'script-fu-register' only get evaluated when the script is registered -- they are not (re-)evaluated when the script is executed. While your code works, you have not really gained anything other than moving the definitions to a different location within the .scm file. (b) But: to make this work I need to be able to determine if a file exists (error if try to load file that doesn't) and to be well- behaved, be able to specify a particular folder in which to look for ini files (same folder as running script? GIMP install folder? GIMP share\gimp\2.0\..?). Any way to test for file existence or determine script folder/install folder in script-fu? It is unclear to me what exactly you mean by to make this work because within a GIMP session, the values set in script dialogs are indeed retained and used the next time the script is executed. If you are wishing to have the values derived at the time the script is run (i.e., calculated before the dialog is presented), this is not readily accomplished. For example, you can't have a size parameter default to the run-time width of the image being filtered -- the initial size default would be evaluated at registration time, and for subsequent executions the previous value entered by the user would be used. If, however, the issue you are attempting to address is having the last values retained across sessions (or survive a Script Refresh), this would be possible by storing your script's last values in the gimpdir/parasiterc file: (define (script-fu-woodrat image drawable bit-width) ; Substitute function owing to buggy parasite-attach behavior (define (fu-parasite-attach parasite) (gimp-parasite-attach parasite) (while (not (string=? (caddr parasite) (caddar (gimp-parasite-find (car parasite) (gimp-parasite-attach parasite))) ; Save the user-specified bit-width to an application parasite (fu-parasite-attach (list WRF_BIT_WIDTH 1 (number-string bit-width))) ... ) (script-fu-register script-fu-woodrat : : : SF-IMAGE ... SF-DRAWABLE ... SF-VALUE Bit width (catch 17 ; fallback value if first-time run (string-number (caddar (gimp-parasite-find WRF_BIT_WIDTH))) ) Note that 'gimp-parasite-find' is only executed once: when GIMP is initially loaded (or if scripts are refreshed). Even though the parasite is saved every time the script is executed, it is actually GIMP's internally stored last value (not the parasite) that is used in determining the value for the 'bit-width' parameter. The only reason you'd want to take these steps is to support last values across different sessions. The behavior you desired (as expressed in the first paragraph of your post) is already supported by GIMP. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

I removed the RUN-NONINTERACTIVE from my script and I was off and running. Here is the final script: I beleive Saul Goode already indicated this is not an error. The calls in the PDB and are correct when calling from a plugin (C or Python). My understanding is that scheme scripts get their functions wrapped in a PDB wrapper when registered, and can not be called interactively from within scheme. This means you can't call the registered PDB function, but instead have to call the scheme script declaration that was registered. If you look in the file selection-round.scm you wil see the declaration: (define (script-fu-selection-rounded-rectangle image drawable radius concave) ... which is what must be called to access this from within scheme.

[Gimp-user] Script-Fu for batch image conversion
Hello folks, I am trying to perform batch conversions of images, including scanned tifs (multi-page), JPGs, and .CR2 raw files. My workflow is as follows: 1) scan/acquire raw images to disk 2) batch convert to XCF 3) hand-edit selected XCFs 4) batch convert to flattened JPG/PNG/etc I am working on a script-fu function for #2, but I'm seeing some odd behavior. When I run the script against JPGs, it creates an XCF for each JPG, but all of the XCFs have the content of the first JPG. I assume I have a scoping problem, or the image variables need to be deleted with each iteration of the while loop, but I'm not having any luck. My second issue is, when I run the script against my scanned 16-bit multi-page TIFs, I get a batch execution failure when calling gimp-image flatten. I haven't started working on the CR2 files yet. Here is the code I'm using: ; START SCRIPT FU (define (batch-save-as-xcf pattern) (let* ( (filelist (cadr (file-glob pattern 1))) (fileparts) (xcfname) (filename) (image) (newimage) (drawable) ) (gimp-message-set-handler 2) (gimp-message Preparing to act on the following files) (gimp-message pattern) (while (pair? filelist) ; set filename to the name of the current file in the glob (set! filename (car filelist)) (gimp-message The current file is: ) (gimp-message filename) ; set xcfname by tokenizing on . and taking everything but the last part (set! fileparts (strbreakup filename .))

Re: [Gimp-user] Script-Fu for batch image conversion
Someone off-list suggested ImageMagick. Some googling shows this command: convert mulitple.tif single%d.tif I think this will create multiple files, each representing a page from the tif. Since I planned on wrapping all my script-fu in PowerShell, I could insert a call to imagemagick to create a temp folder of split-up TIFs, which my script-fu could convert to XCF. I'd rather do the whole thing in script-fu, as I anticipate doing some filtering and stuff via GIMP. If I start down the ImageMagick route, I may just go with a PowerShell/ImageMagick approach and leave out the script-fu. Any strong suggestions on going one way or the other? I'll still do all my manual editing in GIMP, but maybe not any of the batch work ... On Sun, Jun 6, 2010 at 11:03 AM, Dillon dillonontheco...@gmail.com wrote: Thanks Saulgoode, that worked!

It's a little more concerning to me that I found 1 infinite loop that nearly crashed my system (took a while to register, but I finally killed gimp-console) and several memory bugs where a gimp plugin requests gigabytes of memory (and then fails). Also, values aren't garbage collected after fails scripts thus my constant testing lead to a gimp-console taking nearly all of my 4GB of RAM; this forced me to stop using GIMP for the project.

Re: [Gimp-user] Script-Fu Exceptions and errors
Update 2:
1) Exceptions
The macro (not sure of the underlying primitives) catch will catch
errors. The web page didn't even call them exceptions, which explains
why I/google didn't find it quickly.
Ex: when converting an image that might already be RGB to RGB:
(catch (gimp-image-convert-rgb image))
2) The layer issue
As stated before, an earlier command was obliterating my layer and I
forgot to take the head of the get-active-{layer,drawable} in my later
operations.
3) Assertation failures and segfaults
The assertation failures are probably somehow connected with my layer
merging - not that it is good to be able to hit this so easily. I
also found a segfault, do to out of range arguments, since my previous
post and see that this doesn't crash the program - so its running in a
different thread or processs I guess. Not sure if I can catch this
with catch, if I can't then I'll have to fix these corner cases.
Perhaps I'll make some patches for the function documentation if
people are interested.

Hi, On Sun, 2009-09-13 at 23:42 +, Ilya Zakharevich wrote: I am afraid there is no way to do this for tools like 'color select' or 'magic wand'. Tools are a user interface thing and the PDB explicitly doesn't give access to the user interface parts of GIMP. This sentence does not make any sense to me. To make sense, one should have a PRIOR definition of the user interface parts of GIMP. E.g., from what you write, It looks like foreground color is not in the user interface parts of GIMP. The foreground color is part of the context, which is not part of the user interface. The user interface just controls the user context. The fact that script-fu, or rather the PDB, allows to change things in the user context, such as the foreground or background color, is actually a misconception that was made early in the GIMP development. We tried later to correct this by introducing script-specific contexts. But since we didn't want to break existing scripts, we had to introduce 'gimp-context-push' and 'gimp-context-pop'. All scripts that wish to change the context are supposed to use these, so that they get their own context. This way the user context (which is what the GIMP user interface uses), is not affected by scripts. So. is there such a definition? Is it defined as any setting outside those related to save/restore-state Script-Fu API, or is there anything else accessible from Script-Fu?

You can't do that. Is it a defect, or an intentional decision? An alternative would be to use Script-Fu API to walk along a path; but I would need to invoke the current tool at the specified point from Script-Fu, and I can't guess how to find this with the Script-Fu procedure browser... I am afraid there is no way to do this for tools like 'color select' or 'magic wand'. Tools are a user interface thing and the PDB explicitly doesn't give access to the user interface parts of GIMP.

Re: [Gimp-user] Script-Fu
I did not properly present the part about pasting the recomposed image
back into the original layer. You will want to set the offsets of the
pasted layer so that they match the original active layer ('drawable')
and to also anchor your pasted layer. The code should be similar to
the following:
(set! floating-sel (car (gimp-edit-named-paste drawable buffer-name TRUE)))
(gimp-layer-set-offsets floating-sel
(car (gimp-drawable-offsets drawable))
(cadr (gimp-drawable-offsets drawable)))

This is basically an advanced 'Unsharp Mask' I have been doing manually so far, but since I need it very often, would like to make a Script-Fu for this.

There are other scripting language interfaces available. Python (which I prefer myself), Perl, Ruby, and Lua scripting are all available, Python is more standardized than the others. If you have experience with one of those, I suggest to use that language instead. Personally I think almost any language other than Script-fu is a better choice.

[Gimp-user] Script-fu changes?
Hello people. I wrote - quite a while ago - a script to make thumbnails, and modified it for 2.4.x. When I tried to run it in GIMP 2.6.3, it did work correctly, but the screen doesn't update as it should. When the image is scaled, the background doesn't clear, and the scaled image is shown in the upper left corner. The background isn't 'real', meaning it doesn't update when something is moved over. Difficult to put in words. An example is shown here: http://www.jcoppens.com/misc/tests/GIMP.jpg The 'hole' in the middle is where the script dialog was. Is there some extra 'cleanup' necessary in the latest versions? John ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

I did the process manually whereby loading the image at 100dpi then scaling to 300dpi and increasing the width and height by 3 also but the resultant image was quite degraded compared to loading the PDF directly at 300dpi with the appropriate width and heights.

Re: [Gimp-user] script-fu plugin
Hi, I checked your script a little. I have to admit, that I don't know scheme very much, because I don't like LISP very much (Lots of Irritating Superfluous Parentheses). I rather work with perl-gimp. But there is an error in your script. Scheme has a built-in function cons. Cons needs two arguments. There is only given one: (if (= tmp TRUE) (set! viewable (append viewable (cons (aref all-layers (- i 1)) To make it clearer: The one argument is: aref all-layers (- i 1) I don't know which argument to give as second. It would take me a while to figure it out. One other thing is disturbing: In the register-function isn't given if it is a stand allone script or if it should work on an image. I assumed it should work on an image. To test your script I set: Image/Script-Fu/_Copy mask . May be in special cases, the function aref provides twp arguments for cons, for example if you have sufficient layers and layer masks, but in others it doesn*t. Anyhow the error isn't caught. I am working with LINUX, so you see that the error is OS-Independent.

Thanks for all of your help, Torsten. I got it figured out. Emacs wasn't very pleasant, but it led me to see what I needed to do.

I'm still not able to get this to work. Attached is my script (or find it at http://pubpages.unh.edu/~jmb97/SDL/NFont/render-nfont.scm). It produces a bitmap of the characters in a font. I thought the whole first byte was identical between ASCII and UTF-8... Anyhow, maybe someone can get it to work or see what I'm trying to do. Basically, I'm just trying to put the special and accented characters (161, '¡' to 255, ÿ) into a string, but the Gimp isn't outputting anything where they should be. The script appears as NFont-Create NFont. Then you must check the extended ASCII box. I tried using Emacs, but changing the encoding didn't affect anything.

Yes. That isn't working for me. Wouldn't switching the encoding affect the whole file instead of just a particular string? That should do no harm as Gimp is doing about everything in UTF-8 internally. Plus, any characters that are relevant to Scheme syntax (i.e. not strings) are from 7-bit ASCII and won't be touched anyway when you switch to UTF-8. I'm on WinXP, just using Notepad, which can handle the ascii values I'm using (I was surprised that Dr. Scheme can't, however). Strictly speaking, the values that you are talking about are not ASCII (as that only defines 7 bits originally - the upper 127 characters depend on which locale you are in and might even be text graphics). Notepad also stores its data in an encoding, which however is not UTF-8. Typing them into a string isn't working. Hmm... have you tried using the ALT-numpad-sequence for entering the values ? You seem to know the encoding values of the characters in UTF-8, so this might work then with Notepad. Torsten _ Change the world with e-mail.
