Hello,
I wrote command like this:
Code: Select all
convert firstimage.jpg -auto-orient -crop 2508x1791+321+320 stickerimage.png -resize 627 -geometry 600x400+827+1171 -composite -quality 98.0 -density 300 output.jpg
my puopose is to resize the stickerimage.png and put it on the firstimage.jpg with the geometry parameters, but the result is, the resize happened on the firstimage.jpg which lead to the output.jpg only with 600 in width, please help me, i tried to add () arount the stickerimage.png, but it gave me error, how can I change this command to work as I expect, please help.

For a start this looks wrong to me as you should just have an offset:
Code: Select all
-geometry 600x400+827+1171
Should be
-geometry +827+1171
Posting the error may have given more information
Try this:
Code: Select all
convert ( firstimage.jpg -auto-orient -crop 2508x1791+321+320 ) stickerimage.png -resize 627x -geometry +827+1171 -composite -quality 98 -density 300 output.jpg

you are right, just keep offset works fine, but the parenthesis should be placed on the 2nd image
Code: Select all
convert firstimage.jpg -auto-orient -crop 2508x1791+321+320 (stickerimage.png -resize 627) -geometry +827+1171 -composite -quality 98 -density 300 output.jpg

-geometry has two actions (historical reasons)
It resizes tha current last image, and saved the offset for composition.
See IM Examples, Resize, Geometry
http://www.imagemagick.org/Usage/resize/#geometry
You use geometry after reading the first image, so of course that is the image it resized (the only image in memory)
using -geometry for resizing is NOT recommended.
