Hi everybody,

I want to convert a FITS image into PPM in batch mode. Grabbing code from different sites I end up to a source script version like this:

(define (fits-to-ppm infile outfile)
(let* ((image (car (file-fits-load
RUN-NONINTERACTIVE
infile
infile
)
)
(drawable (car (gimp-image-get-active-layer image)))) (file-ppm-save RUN-NONINTERACTIVE image drawable outfile outfile 0) (gimp-image-delete image)
)
)
)

When I run this in the command line (in the same directory where "mask.fits" reides) I get this result:

$ gimp -i -b '( fits-to-ppm "mask.fits" "mask.ppm")' '(gimp-quit 0)' No batch interpreter specified, using the default 'plug_in_script_fu_eval'. batch command: executed successfully.

However, no file "mask.ppm" appears in the directory where I'm executing gimp :-(

Any ideas what's going on? Whatever comments/hint will be very welcome.

Thanks in advance,

Octavi.

still no output file even when including the directory name in the name of the files...

Can this silent error have to do with the fact that gimp asks Blank/Nan value" and "Pixel value scaling" when loading the FITS image (which I'm attaching to the message)?

Best regards,

Octavi.

They are the same. The GIMP process doesn't change the current working directory and it uses it as the default directory when saving. So do the plug-ins, at least the ones that are distributed with GIMP.

Thanks Pere!

the script worked fine once I included your tip. I'm surprised gimp interpreter didn't warn that...

Anyway, now the output "mask_gimp.ppm" file is generated. However, this is a greyscale one in ASCII (magic number is P2) and would like to output a color one in ASCII (magic number is P3).
Can I also do this in the same script below?

(define (fits-to-ppm infile outfile)
(let* ((image (car (file-fits-load RUN-NONINTERACTIVE infile
infile
)
)
)
(drawable (car (gimp-image-get-active-layer image))) )
(file-ppm-save RUN-NONINTERACTIVE image drawable outfile outfile 0) (gimp-image-delete image)
)
)

Any help on this will be very welcome.

Regards,

Octavi.

; Here you lack a ) closing (image

(drawable (car (gimp-image-get-active-layer image))))

(file-ppm-save RUN-NONINTERACTIVE image drawable outfile outfile 0) (gimp-image-delete image)
)
)

Here you should remove the ) added before

Hope this helps

Pere,

yes! It worked. The script is:

(define (fits-to-ppm infile outfile) (let* ((image (car (file-fits-load RUN-NONINTERACTIVE infile infile))) (drawable (car (gimp-image-get-active-layer image))) )
(gimp-image-convert-rgb image)
(file-ppm-save RUN-NONINTERACTIVE image drawable outfile outfile 0) (gimp-image-delete image)
)
)

Thanks so much for helping,

Octavi.

You should insert a (gimp-image-convert-rgb image) before saving.
