Constructor for creating a template in an existing PDF document.

Parameters

pdfDocument	Associated PDF document
templateWidth	Width of the template in user units
templateHeight	Height of the template in user units

Example

wxPdfDocument pdf;
pdf.AddPage();
double w = 125, h = 125;
int tpl = pdf.BeginTemplate(0, 0, w, h);
{
    wxPdfDC dc(&pdf, w, h);

SetResolution()

SetImageType()

void wxPdfDC::SetImageType	(	wxBitmapType	bitmapType,
		int	quality = 75 )

Sets the image type and quality for bitmap output.

Parameters

bitmapType	The type of the bitmap (e.g., wxBITMAP_TYPE_JPEG)
quality	Compression quality from 0 to 100

SetMapModeStyle()

void wxPdfDC::SetMapModeStyle

(

wxPdfMapModeStyle

style

)

Sets the map mode style.

Map mode style determines how logical coordinates and font sizes are scaled to the PDF page, allowing emulation of platform-specific behaviors or native PDF API scaling.

Parameters

style
