◆ mapPageToView() [1/2]

QRectF QPdfDocumentPrivate::mapPageToView ( FPDF_PAGE pdfPage,
double left,
double top,
double right,
double bottom ) const

Convert the bounding box defined by left top right and bottom to the usual 1x (pixels = points) 4th-quadrant "view" coordinate system that we use for rendering things on top of the page image. Some PDF files have internal transforms that make this coordinate system different from "page coordinates", so we cannot just subtract from page height to invert the y coordinates, in general.

Definition at line 501 of file qpdfdocument.cpp.

◆ mapPageToView() [2/2]

QPointF QPdfDocumentPrivate::mapPageToView ( FPDF_PAGE pdfPage,
double x,
double y ) const

Convert the point x , y to the usual 1x (pixels = points) 4th-quadrant "view" coordinate system relative to the top-left corner of the rendered page. Some PDF files have internal transforms that make this coordinate system different from "page coordinates", so we cannot just subtract from page height to invert the y coordinates, in general.

Definition at line 483 of file qpdfdocument.cpp.

◆ mapViewToPage()

QPointF QPdfDocumentPrivate::mapViewToPage ( FPDF_PAGE pdfPage,
QPointF position ) const

Convert the point x , y from the usual 1x (pixels = points) 4th-quadrant "view" coordinate system relative to the top-left corner of the rendered page, to "page coordinates" suited to the given pdfPage, which may have arbitrary internal transforms.
