Yes, it is a must unless you are using GIMP 2.4 or earlier. The TinyScheme component of GIMP more closely follows the Scheme standard. The standard requires variables in a lot block to have an initial value, and all variables must be declared before first use. You should take a look at the Script-Fu migration guide at http://www.gimp.org/docs/script-fu-update.html and my notes at http://www.ve3syb.ca/wiki/doku.php?id=software:sf:updating-scripts (which cover most of the same points). > I think that this line is not returning the number of layers as we're > expecting.

[snip] > (gimp-message "The current file has the following number of layers: ") > (gimp-message num-layers) The problem with the above is you are passing an integer to gimp-message instead of passing a string. You need to wrap num-layers in a call to number->string. You can combine the two calls to gimp-message so the number of layers appears in the message by doing the following: (gimp-message (string-append "The current file has the following number of layers: " (number->string num-layers))) _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
