Hello,
I want to convert files with the extension .png to .gbr format on batch. To do that I used a script found on the web: brush-batch.scm. This one does not work on my computer that is why I used it to create a new one. My code is lauching but it stops during loading file.
If you can help me to understand why that could be great.

This is my code:
(define (convert-pngtogbr load name location)


(gimp-context-set-foreground '(0 0 0))
(gimp-context-set-background '(255 255 255))
(let* (
(filelist (cadr (file-glob (string-append load "\\*.png") 1)))
(s 1)
)
(while filelist
(let* (
(loadfile (car filelist))
(image (car (gimp-file-load RUN-NONINTERACTIVE loadfile loadfile)))
)
(set! drawable (gimp-image-get-active-drawable image))
(set! filename2 (string-append location "/" name ".gbr"
))
(file-gbr-save 1 image drawable filename2 name 15 name))
(set! s (+ s 1))
(gimp-image-delete (car image))
(set! filelist (cdr filelist))))
)
(script-fu-register "convert-pngtogbr"
"<Toolbox>/Xtns/Script-Fu/PngToGbr..."
"Convert png to gbr"
"XX"
"XX"
"Juin 2016"
""
SF-DIRNAME "Load from" ""
SF-STRING "Brush Name" "name"
SF-DIRNAME "SAVE TO FOLDER" "")

Thank you very much
Best regards

It's so much easier to read if you put it in [ code ] tags:


I've not tried it, but one obvious problem is that you've not defined drawable or filename2 before using them.

Thank you for your information about code tag. I will use it now.

filename2 is defined as that:


and drawable as that:


The problem seems to come from uploading file. On the screen, the dialog box closes at that time.

Thank you

No!

You have to define something BEFORE you use set!

otherwise you get this:


Kevin

OK. Do you have an example?
I join the code I used because I did not understand where and how I have to do what you said.

Thank you
