I want to reduce an image so that it is no larger than 100x80 pixels.
I then want the reduced image to be centered on a larger canvass.
Under Paint Shop Pro, I'd open the image then
>> image >> resize >> 100x80
>> image >> canvas size >> 100x80 centered on white
With ImageMagick I tried:
convert -geometry 100x80 image1.jpg image2.jpg
convert -size 100x80 xc:white canvas.jpg
composite image on canvas
composite image2.jpg canvas.jpg image3.jpg
It doesn't center
I can't seem to find out how to get image2.jpg centered on canvas.jpg.
And can it all be done in one command line?
