See rotate examples, in "Distorting Images" http://www.cit.gu.edu.au/~anthony/graphics/imagick6/distorts/#rotate Especially the last example, wich uses a compose to crop the image back to its original size after the rotation. | -something like convert -extent but the image is | centered and the background if filled with desired | color. | You can do -extent with a specific color quite simply. Use a viewport crop (add a ! flag), to crop/extend the image canvas to the desired size, then 'flatten' it to fill out that canvas with the desired color.. convert rose: -crop 100x100+0+0\! \ -background blue -flatten \ rose_extent_blue.png You can even offset the image on the canvas, though remember the crop positions the 'viewport' or window, so the offset is for the canvas, NOT for the image. EG use a negative offset for a positive image offset convert rose: -crop 100x100-20-20\! \ -background blue -flatten \ rose_extent_blue_offset.png This is slowed than -extent which is designed for speed, in resizing images that will be completely rebuild, or the user does not care about what goes into any extra space. for more info see "Cutting and Bordering" examples http://www.cit.gu.edu.au/~anthony/graphics/imagick6/crop/ Specifically Viewport Crop http://www.cit.gu.edu.au/~anthony/graphics/imagick6/crop/#crop_viewport Anthony Thyssen ( System Programmer ) <[EMAIL PROTECTED]> ----------------------------------------------------------------------------- Did you ever have the feeling that the world was an AC coffee pot and you were DC? -- Dean Alan Foster, `` Glory Lane '' ----------------------------------------------------------------------------- Anthony's Home is his Castle http://www.cit.gu.edu.au/~anthony/ _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
