Close.. but apparently it is forcing me to load an image first before setting a resolution (which by then is too late to fix it.)
% $w SetResolution 300 300 Wand contains no images `MagickWand-1' In your cmdline example, that works great except that it resamples and ruins the sharpness of the images. I'll have to test them to see if they're scannable. And yes, we DO want to convert these to raster. Is there a way to force resolution on an empty wand so that loading an image into it won't change it? > [EMAIL PROTECTED] on wrote... > | I have done due diligence and must admit defeat on this.
