program PDFViewWin;
|
|
// this program opens and closes PDF-files with Acrobat or Adobe Reader
|
|
// author: Uwe Stöhr
|
|
|
|
{The problematic is the following:
|
|
A PDF-file should be modified while it is opened with Acrobat.
|
|
This is not possible because Acrobat understands itself as editor, not as
|
|
reader and therefore opens PDFs always with write access, so that other
|
|
programs cannot modifiy them.
|
|
The idea to solve the problem is the following:
|
|
The file that should be shown in Acrobat is copied and then renamed -
|
|
the suffix "-preview" is attached. The renamed copy is opened by Acrobat
|
|
while the unrenamed version can be modified. When the modified version should
|
|
be displayed, the eventually opened renamed version is closed in Acrobat and
|
|
the modified version is copied, renamed and opened in Acrobat.}
