If you have access to a Windows PC, then the Windows accessory, MS Paint can be used for this. File>Open>filename.jpg (or filename.bmp; or filename.gif)
Then Image>Attributes>Colors choose B/W radio button Save then file, under a different name or you would loose your original Or save the original under a diiferent name before changing from color to black and white, and save the Black and white under the name called out by your reports There are many free or open source image editors out there. Do as little as possible to your image to preserve the best image quality. Paint cannot handle every image type, just the simple rasters, not PNG for instance. > From: [email protected] > To: [email protected] > Date: Fri, 22 May 2009 14:05:15 -0500 > Subject: RE: [U2] pcl imaging question... > > What does work for us, is the way you suggested.
