You need to use 'display' instead of 'write', and output the offsets individually (or construct a string using 'string-append'; 'display' only accepts one object at a time). (if (= (car bounds) 0) (display "0,0" p) (begin (begin (display (- (cadr bounds) x) p) (display "," p) (display (- (cadddr bounds) x) p) ) ) ) More information about handling Scheme's I/O is available at: http://www.schemers.org/Documents/Standards/R5RS/HTML ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Since the operation mode of 'gimp-rect-select' is
CHANNEL-OP-INTERSECT, the resulting selection is only the
non-transparent part of all chars that lie within the region of that
cell (i.e., the non-transparent part of a single char).
This is the opposite order of what you may have been expecting -- that
is, to select a cell and THEN select the non-transparent part of the
cell -- but the net result is the same! It was simpler to do it my way
because the "Alpha To Selection" function
('gimp-selection-layer-alpha') does not allow for CHANNEL-OP modes.

Re: [Gimp-user] Help with script
The comma isn't the problem; there's nothing special about commas in Scheme strings. It's the output function you're using - (write) formats things in Scheme source-code form so they can be (eval)'ed when read back in. To just output some text as text, use (display) instead. For a single comma you could also use (write-char #\,). On 1/15/09, none wrote: > Hi again. I just have one question about the script.
