TPostScriptPrinterCanvas.GetTextMetrics function

Declaration

function GetTextMetrics(out TM: TLCLTextMetric): Boolean; override

Description

Not described here; this is what TCanvas.GetTextMetrics says of it:

Gets physical dimension of the currently selected font of the canvas.

Calls RequiredState to check state flags for the canvas, and ensure that the Handle and the Font are valid. RequiredState raises an Exception if the Handle for the canvas is not valid.

Calls GetTextMetrics in the LCL interface to retrieve the ascender, descender, and height metrics for the canvas Handle. The values are assigned to members in the TM output argument.

The return value is True when text metrics were successfully retrieved from the widgetset.
