| Hi there, | | this is my first Post on this list and I hope you can help me. | | I'm running Imagemagick (Version: ImageMagick 6.4.3 2008-12-03 Q16 OpenMP | http://www.imagemagick.org) on a linux machine and I have a set of | Photoshopimages in varying sizes that I would like to convert into JPG. | | I have to extract a clipping path, put it in the middle on a blue canvas with | a size of 2000x2000 pixel and save this image, resize it in the next step and | add a watermark image.

I played around with some options (-draw 'color 0,0 | floodfill' changed position of command line options). | | Can anyone help me to get those two calls together? | First it would have been better if you could have formated your command into multiple lines so one major image processign step is on each line. That makes it a LOT easier to read! Second a canvas is NOT needed for -flatten, as it will create a canvas as part of its processing. Also -flatten does NOT understand -gravity. That is a composite setting not a image layering setting. For info see Composite Geometry/Gravity vs Layer Canvas/Page Offsets http://www.imagemagick.org/Usage/compose/#geometry Also look at examples on flattening, with canvas adjustments (using -page) http://www.imagemagick.org/Usage/layers/#flatten I suggest you use -composite instead, in whcih case you will need to generate the canvas image. Downloading images.. | If you need an image for testing purposes you can get it at: | | http://ar.nutzerverwaltung.de/foto.psd (careful, it has ~33 MB) | The watermarkimage is available here: | http://ar.nutzerverwaltung.de/stempel_axel.png I get errors with that image! identify: Improper image header `foto.psd' @ psd.c/ReadPSDImage/662. So I am unable to continue, as I can't see how your 'clipping' mask is being handled.
