How can I do that? With gimp, it is simply changing the dimensions of the canvas.</p>PeterWed, 04 Apr 2012 05:28:13 -0000http://dptnt.com/2007/09/batch-resize-images-using-imagemagick/#comment-356676176<p>Great stuff, very useful. <br>Thank you.</p>dRewsusFri, 30 Jul 2010 22:52:18 -0000http://dptnt.com/2007/09/batch-resize-images-using-imagemagick/#comment-356676175<p>nice tips, synthetic and useful.<br>Thanks</p>F@bSat, 24 Jan 2009 09:28:38 -0000http://dptnt.com/2007/09/batch-resize-images-using-imagemagick/#comment-356676174<p>Thank you for pointing it out!
