Subject RES: merging images from a compact-pdf file
Date Tue, 23 Nov 2010 18:21:43 GMT
Hello Glenn, 
There is an example that show how to do that.

Is a class called PrintImageLocations, the problem is to process the entire
stream to find this information.
Maybe you can adapt it to process the stream once and store those locations
in a data structure.

Assunto: merging images from a compact-pdf file

I've been using pdfbox to do processing on documents scanned with our 
office copy machines (Cannon and Ricoh machines).  Normally, the resulting 
pdf files contain one TIF file per page and the page.converttoimage() 
function works fine to extract the image.  One of the machines has a 
setting to produce 'compact pdf' files which produces a smaller file. When 
the compact feature is turned on, instead of a single TIF image being 
stored in the page, multiple images are stored which need to be 
reassembled into a single image through some type of merging process.

I am able to extract the separate images but I'm missing the roadmap on 
how to size the images and recombine them.  Is there some sort of property 
which provides relative x,y coordinates so I can recombine using a 
graphics drawImage method?
