For this example, lock the width and height together by clicking on the broken chain, and choose 750 px. You can see the boundary of the image is a dashed line.Ĭhose the scale button on the toolbarto scale the image. Keep doing this unitl you see the top let corner of the image.

Go to the folder you have your uncompressed image stored. Note: The white box is the only part of the image you will be able to see and export. Resize the window to see more of the gray area.

The remaining code is justtheneeded boiler plate to registerĪfter shrinking my canvas using Image -> Canvas (and centering the layers as desired), the Layer -> Layer to Image Size did the trick (without scaling the image). When picking the action from the menu, and there are two extra calls so thatīoth scalignand centering are 'undone' as a single action. Note it is the same code than above, but 'img' and 'layer' are now suplied by GIMP Scale_layer_to_canvas_size, menu='/Layer/', (PF_DRAWABLE, 'layer', 'Input drawable', None), ], , [(PF_IMAGE, 'image', 'Input image', None), 'Scales the layer to canvas size, keeping the aspect ratio',

Layer.scale(int(layer.width * factor), int(layer.height * factor))

On Linux and Mac OS, any extension would work, but you have to give the fileĪfter restarting GIMP, you will have the new command conveniently located on your Layer menu: #! /usr/bin/env pythonĭef scale_layer_to_canvas_size(img, layer):įactor = min (float(img.width) / layer.width, Paste the contents bellow as a file there (if on Windows, the file must have the '.py' extension. Just check your edit->preferences->folders->plug-ins for your plug-in directory, Pick the image or layer to resize, I formated it as a python-script for GIMP as well. Since this can be done, but is not practical, even more because it does not allow you to img = gimp.image_list() layer = img.layers factor = min (float(img.width) / layer.width, float(img.height) / layer.height) layer.scale(int(layer.width * factor), int(layer.height * factor)) t_offsets((img.width - layer.width) / 2, (img.height - layer.height) / 2) On the top layer of the most recent open image. On the width or height, and use this ratio to scale tha layer, and then center the layer.įor your convenience, I wrote some Python code for this in a single line, in a way you can just copy and paste on the python console (filters->python->console) to apply the effect What have to be determined programatcially is whether the ratio of the image/layer is larger The way out is to use the program's scripting capabilities to perform the action: This is easy to do, but among the hundreds of possible options to be put on the program UI, it was not 'elected' to be there. An alternative without any scripts is: Layer -> Scale Layer That feature is not in gimp for some reason.
