Windows PDF view helper
|
|
Author: Joost Verburg and Uwe Stöhr
|
|
|
|
This will be installed as pdfview.exe.
|
|
|
|
The application will launch the default PDF viewer to display the PDF file,
|
|
but works around the file locking problems of Adobe Reader and Acrobat.
|
|
|
|
The files pdfopen/pdfclose are part of this archive:
|
|
