问题
I have modified one pdf appending the xrefstream using incremental update http://www.filedropper.com/temp_4 , which is opening fine with Mac's preview app, but not able to open it with adobe's acrobat reader, why is that so...? Special request to Acrobat reader developer to respond on this.
回答1:
The EOF markers are strange: %%%EOF and %%%%EOF instead of %%EOF. When chaning the last marker to %%EOF the file is read by Acrobat.
Anyhow the /Length value is still wrong 19 should be changed to 20.
