GetUseTransparency
Syntax:
LBOOL pdfGetUseTransparency(
const PPDF* IPDF) // Instance pointer
The property specifies whether images should get a transparent background. If true, the transparent
color (see SetTransparentColor() is used to mask an image. The property has no effect for JPEG
compressed images.
Default value = 1 (true)
GetUseVisibleCoords
Syntax:
LBOOL pdfGetUseVisibleCoords(
const PPDF* IPDF) // Instance pointer
The property specifies whether DynaPDF should consider the crop box to calculate the position of
an object. The crop box crops a page, but the paper format (media box) is left unchanged. To move
the coordinates into the visible area, set the property to true. Coordinates can then be used as if no
crop box was defined. The bounding boxes are described in detail at SetBBox().

LBOOL pdfGetViewerPreferences(
const PPDF* IPDF,
