%Docstring
|
|
Returns the font metrics for the given text ``format``, when rendered
|
|
in the specified render ``context``. The font metrics will take into account
|
|
all scaling required by the render context.
|
|
|
|
The optional ``scaleFactor`` argument can specify a font size scaling factor. It is recommended to set this to
|
|
QgsTextRenderer.FONT_WORKAROUND_SCALE and then manually scale painter devices or calculations
|
|
based on the resultant font metrics. Failure to do so will result in poor quality text rendering
|
|
at small font sizes.
