Greetings all - happy new year,
I''m having problems getting Pdf::Writer image insertion.
pdf.image "/path/to/images/logo.jpg"
is firing "JPEG marker not found!"
Originally created the RGB (8 bit) JPEG in photoshop. After the above,
I''ve exported with an alternate tool using (OSX) preview.
This tutorial
http://www.artima.com/rubycs/articles/pdf_writer2.html
says that CMYK or RGB encoding is needed - so that''s not the problem.
Other than that requirement, are there others?
Optionally I tried PNG, but this resulted in a nil.unpack error (''The
error occured while evaluating nil.unpack'')
I''ve now run out of file types. harumph!
Secondary question, how do I reference a relative path to the file
(/images and ../images/file don''t work) ? Or perhaps a way to find the
server root path from the os?
Thanx for any pointers.

PDF::Writer will work from the current working directory, and that may not be what you think it is in the file you''re dealing with. -austin -- Austin Ziegler * halostatue@gmail.com * Alternate: austin@halostatue.ca

Check to make sure your JPEG isn''t progressive. This is general advice, because I don''t know PDF::Writer. Your problem may very well be something else. For relative paths, I use File.join RAILS_ROOT, "path", "to", "file" -- Kyle Maxwell Chief Technologist E Factor Media // FN Interactive kyle@efactormedia.com 1-866-263-3261
