[babwar]

hello,

I have a little problem using imagemagick.

What i want to do is create an image with x images.

It is working perfectely like this :

convert -size 285x285 xc:#1582cb \
image1.jpg -geometry 129x65+13+15 -composite \
image2.jpg -geometry 114x51+159+217 -composite \
final.jpg

But it take exactely image1.jpg and image2.jpg. I want to make a crop from this images in add.

Thanks for your answers..

You can crop images when reading them using special image read modifiers. These include, resizing, or cropping the images being read. To do both use the crop method, the resize.
http://imagemagick.org/Usage/files/#read_mods

the alturnative is to use parenthesis to process just the one image before adding it to the canvas.

Code: Select all

   convert canvas.png \
           ....
           \( new_image.jpg  -crop 100x100+20+30 +repage \
                    -resize 50x50   -repage +300+200 \) \
           ....
           -flatten   result.png

Parenthesis... http://imagemagick.org/Usage/basics/#parenthesis
the -flatten is type of multi-image -composition operator.
See Image layering http://imagemagick.org/Usage/layers/
It also can create a background canvas of a specific size, basied on the virtual canvas size of the first image in the image sequence.

Basically you have only just scratched teh surface of multi-image compositions.
