Detailed Description

\inmodule QtGui

The QPdfWriter class is a class to generate PDFs that can be used as a paint device.

QPdfWriter generates PDF out of a series of drawing commands using QPainter. The newPage() method can be used to create several pages.

Definition at line 20 of file qpdfwriter.h.

Member Enumeration Documentation

◆ ColorModel

enum class QPdfWriter::ColorModel

strong

Since: 6.8

This enumeration describes the way in which the PDF engine interprets stroking and filling colors, set as a QPainter's pen or brush (via QPen and QBrush).

\value RGB All colors are converted to RGB and saved as such in the PDF.

\value Grayscale All colors are converted to grayscale. For backwards compatibility, they are emitted in the PDF output as RGB colors, with identical quantities of red, green and blue.

\value CMYK All colors are converted to CMYK and saved as such.

\value Auto RGB colors are emitted as RGB; CMYK colors are emitted as CMYK. Colors of any other color spec are converted to RGB. This is the default since Qt 6.8.
