Performance when opening large pdf documents...

Post by Robbi »

Our clients often have to open very large documents (>1.000 pages, > 50 MB). If they use the Acrobat Reader V8 the first page appears on the screen in the first(!) second.

Using the PdfXChange Viewer/SDK the complete file will be analysed(?)/scanned/read at first and after that the first page will be displayed. This may need about half a minute or more (pdf file with 350MB!) These big pdf documents cannot be split to reduce the time for opening.

Any idea, how the Acrobat Reader works and how to implement this performance gain into the PdfXChange viewer?

Hi.

For now the PDF-XChange viewer is gathering all information for annotations and forms during the file opening process. Later we are planning to change this behaviour and this should dramatically improve file opening speeds.
