|
|
* Task G4 – PDF-Export je Layout im Ausgabemaßstab.
|
|||
|
|
*
|
|||
|
|
* exportLayoutPDF rendert den Layout-Viewport (center/scale) auf eine A4-
|
|||
|
|
* Seite (landscape), skaliert Weltkoordinaten in den Ausgabemaßstab,
|
|||
|
|
* berücksichtigt Linienbreiten aus Layern (lineType) und unterstützt
|
|||
|
|
* eine monochrome Option. Titelblock (frameBlockRef) wird mitgezeichnet.
|
|||
|
|
* Rückgabe: PDF-Bytes, per PDFDocument.load verifizierbar.
