Re: [Gimp-user] Script-Fu: remove Exif, thumbnail, color profile when saving PNG
After Open the Image, Get width and height.
Copy the image.
Create a new image using the values.
Add a new layer from the copy into the new image.
Export to the file.
OR
Set metadata-string to NULL ("")
Do pdb gimp-image-set-metadata
(Notice; Only Remove EXIF)
Example on Console
> (define metadata-string "")
metadata-string
> (define image 1)
image
> (gimp-image-set-metadata image metadata-string)

Re: [Gimp-user] Script-Fu: remove Exif, thumbnail, color profile when saving PNG
Why do you use Gimp for this... You script would run faster using
ImageMagick (for the conversion) and ExifTool (to remove the Exif data):
convert in.png PNG8:out.png
exiftool all= out.png

Hello, I have written a Script-Fu batch program that is intended to
reduce the file size of a PNG image ("in.png") by converting it into
"indexed" mode with a color palette of 16 colors, and saving the output
("out.png"):
#!/bin/sh
gimp-console --batch '
(let* ((image (car (gimp-file-load RUN-NONINTERACTIVE "in.png" "in.png")))
(drawable (car (gimp-image-flatten image)))
(outfile "out.png"))
(gimp-image-convert-indexed image
CONVERT-DITHER-NONE
CONVERT-PALETTE-GENERATE
16 FALSE FALSE "")
(file-png-save2 RUN-NONINTERACTIVE image drawable outfile outfile FALSE 9
FALSE FALSE FALSE FALSE FALSE FALSE FALSE))
(gimp-quit 0)'
This script works. However, it always includes Exif data, thumbnail, and
the color profile when I save the PNG, which I do not want because they
make the saved image larger. I know that if I change `(file-png-save2
RUN-NONINTERACTIVE ...)` to `(file-png-save2 RUN-INTERACTIVE ...)`, a
dialog will pop up where I can uncheck the "Save Exif data", "Save
thumbnail", and "Save color profile" checkboxes. I want to disable the
"Save Exif data", "Save thumbnail", and "Save color profile" in a
non-interactive way (i.e. without requiring the interactive dialog box)
when saving a PNG. How can I do that?
