Well, following all advices I decide to make the plugins I need for gimp, and use it in batch mode, this way plugins will be available for everybody. But my first attempt is not working fine, I'm coping/pasting the following code into the script-fu console, and I get a black image as glam-out.jpg with correct size, could you tell me why ?, (this is a test that should make an image which is double in height than input, and the upper half size has the input copied as is and the lower half size has the input copied rotated 180) (let* ( (image (car(gimp-file-load 1 "/home/pablo/glam.jpg" "/home/pablo/glam.jpg"))) (width (car (gimp-image-width image))) (height (car (gimp-image-height image))) (newheight (* height 2)) (newimage (car(gimp-image-new width newheight RGB))) (newlayer (car (gimp-layer-new newimage width newheight RGBA-IMAGE "Copy" 100 NORMAL-MODE))) ) (gimp-context-push) (gimp-image-add-layer newimage newlayer -1) (gimp-drawable-set-visible newlayer TRUE) (gimp-selection-all image) (gimp-edit-copy-visible image) (gimp-rect-select newimage 0 0 width height CHANNEL-OP-ADD FALSE 0) (let ((floating-sel (car (gimp-edit-paste newimage FALSE)))) (gimp-floating-sel-anchor floating-sel) ) (gimp-selection-none newimage) (gimp-rect-select newimage 0 height width height CHANNEL-OP-ADD FALSE 0) (let ((floating-sel (car (gimp-edit-paste newimage FALSE)))) (gimp-rotate floating-sel FALSE 180) (gimp-floating-sel-anchor floating-sel) ) (gimp-file-save 1 newimage newlayer "/home/pablo/glam-out.jpg" "/home/pablo/glam-out.jpg") (gimp-context-pop) ) Best Regards, Pablo On Sunday 14 December 2008 16:36:10 saulgoode@xxxxxxxxxxxxxxxxxxxxxxxxxxxxx wrote: > Quoting Pablo Yaggi <pyaggi@xxxxxxxxxxxxxxx>: > > So ..., I think a couple of things are not clear to me about gimp, > > if plugins communicate with the core of gimp thought a pipe, I > > should be able to create a plugin to do what i want, even > > call other plugins, but could that plugin be executed from outside > > the core ?, ... > > Yes. > > > even so it is necesary that gimp is running before > > doing it ? > > Yes, if you want to use plug-ins or scripts then you will want GIMP to > be running (unless you want to reimplement all of the functionality of > handling those plug-ins using libgimp). > > > are the core and gui strict releated, i mean are the same > > thing? can the gui be down, and the core working ? > > Yes, you can execute GIMP without the GUI by passing the > '--no-interface' ('-i') option on the command line.
