I am able to compose two images with this command
Code: Select all
magick original/20190604_153319_0001.TIF corrected/temp/streaks/20190604_153319_0001.png -compose plus -composite x.png
but when I try to set the extent, the output image is completely white
Code: Select all
magick original/20190604_153319_0001.TIF corrected/temp/streaks/20190604_153319_0001.png -compose plus -composite -extent 2550x3300 x.png
In this example 2550x3300 are the original dimensions of both images being composited.
Why does this happen? Is there a way to compose and set the extent in one command?

I forgot to mention, I want to set the extent on the image after the two have been composited, not on just the background or overlay.

after -composite add -compose over to reset the compose method. -extend uses the current compose, which you have as plus.-compose over -extent 2550x3300 x.png
