Function

Pango.extents_to_pixels

Declaration [src]

void
pango_extents_to_pixels (
  PangoRectangle* inclusive,
  PangoRectangle* nearest
)

Description [src]

Converts extents from Pango units to device units.

The conversion is done by dividing by the PANGO_SCALE factor and performing rounding.

The inclusive rectangle is converted by flooring the x/y coordinates and extending width/height, such that the final rectangle completely includes the original rectangle.

The nearest rectangle is converted by rounding the coordinates of the rectangle to the nearest device unit (pixel).

The rule to which argument to use is: if you want the resulting device-space rectangle to completely contain the original rectangle, pass it in as inclusive. If you want two touching-but-not-overlapping rectangles stay touching-but-not-overlapping after rounding to device units, pass them in as nearest.

Parameters

rectangle to round to pixels inclusively, or NULL.

 Can be NULL
 The data is owned by the caller of the function
nearest PangoRectangle
 

rectangle to round to nearest pixels, or NULL.

 Can be NULL
