  • How to set X-Resolution and Y-Resolution 70 files as a batch operation?

    example:

    (define (simple-unsharp-mask filename
    radius
    amount
    threshold)
    (let* ((image (car (gimp-file-load RUN-NONINTERACTIVE filename filename)))
    (drawable (car (gimp-image-get-active-layer image))))
    (plug-in-unsharp-mask RUN-NONINTERACTIVE
    image drawable radius amount threshold)
    (gimp-file-save RUN-NONINTERACTIVE image drawable filename filename)
    (gimp-image-delete image)))

    "simple-unsharp-mask" must it be something like "xy-resolution"?

    I can't find it (publisher wants 150 DPI that must be 150 X-Resolution and 150 Y-resolution)

    1. Unsharp mask is used, despite its name, to sharpen an image.

    2. Many people find GIMP's scripting language too difficult and
    decide to use Image Magick instead for batch updates.
