montage problem

You can crop the image data (not from the displayed image). See http://www.imagemagick.org/Usage/crop/#crop and http://www.imagemagick.org/script/comma ... s.php#crop

Code: Select all

Why do you have a colon? Try:

Code: Select all

convert 4.jpg -crop ...

[fmw42]

convert 4.jpg: -crop 23x27+89+77 crop.jpg

The colon is the problem. Only IM internal images such as logo: and rose: use colons. try

Code: Select all

convert 4.jpg -crop 23x27+89+77 +repage  crop.jpg

The repage is needed to remove the virtual canvas, which is important for format such as gif and png and tif that save the virtual canvas. Jpg does not save it, so you are safe leaving it off. But it is good practice to add it unless you want to keep the virtual canvas.

Can I increase image size?

[fmw42]

What do you mean by increase image size? Do you mean to magnify the image, i.e. make the whole image bigger at every pixel or just add a border around the image. To resize and image:

Code: Select all

convert image -resize WxH newimage

where W and H are the new image dimensions or can be percents. See http://www.imagemagick.org/script/comma ... php#resize and http://www.imagemagick.org/script/comma ... p#geometry

To add a border around an image:

Code: Select all

convert image -bordercolor somecolor -border X newimage

where X is the thickness of the border in pixels.
