[magick-developers] adding exif information

[Jonathan Howland]

I am trying to add exif info to a jpeg file.  Looking at the docs, I 
implemented code like this:

Image image(width,height, "RGB", CharPixel, imageData);
image.attribute("EXIF:ImageDescription",eData);
       
 image.write(fileName);

where eData is a character string.  When I try and read the resulting 
exif tags from the image, I get a notation that there are no exif 
tags--ThumbsPlus can't read exif info either, etc.  Am I doing something 
wrong, or do I need a better reader?

thanks

Jonathan Howland
