|

* GtkPrintContext:
|
||||
*
|
||||
* A GtkPrintContext encapsulates context information that is required when
|
||||
* drawing pages for printing, such as the cairo context and important
|
||||
* parameters like page size and resolution. It also lets you easily
|
||||
* create #PangoLayout and #PangoContext objects that match the font metrics
|
||||
* of the cairo surface.
|
||||
* A `GtkPrintContext` encapsulates context information that is required when
|
||||
* drawing pages for printing.
|
||||
*
|
||||
* GtkPrintContext objects gets passed to the #GtkPrintOperation::begin-print,
|
||||
* #GtkPrintOperation::end-print, #GtkPrintOperation::request-page-setup and
|
||||
* #GtkPrintOperation::draw-page signals on the #GtkPrintOperation.
|
||||
* This includes the cairo context and important parameters like page size
|
||||
* and resolution. It also lets you easily create [class@Pango.Layout] and
|
||||
* [class@Pango.Context] objects that match the font metrics of the cairo surface.
