Graphics::MeasureDriverString method (gdiplusgraphics.h)

The Graphics::MeasureDriverString method measures the bounding box for the specified characters and their corresponding positions.

Syntax

Status MeasureDriverString(
  [in]  const UINT16 *text,
  [in]  INT          length,
  [in]  const Font   *font,
  [in]  const PointF *positions,
  [in]  INT          flags,
  [in]  const Matrix *matrix,
  [out] RectF        *boundingBox
);

Parameters

[in] text

Type: const UINT16*

Pointer to an array of 16-bit values. If the DriverStringOptionsCmapLookup flag is set, each value specifies a Unicode character to be displayed. Otherwise, each value specifies an index to a font glyph that defines a character to be displayed.

[in] length

Type: INT

Integer that specifies the number of values in the text array. The length parameter can be set to –1 if the string is null terminated.

[in] font

Type: const Font*

Pointer to a Font object that specifies the family name, size, and style of the font to be applied to the string.

[in] positions

Type: const PointF*

If the DriverStringOptionsRealizedAdvance flag is set, positions is a pointer to a PointF object that specifies the position of the first glyph. Otherwise, positions is an array of PointF objects, each of which specifies the origin of an individual glyph.

[in] flags

Type: INT

Integer that specifies the options for the appearance of the string. This value must be an element of the DriverStringOptions enumeration or the result of a bitwise OR applied to two or more of these elements.

[in] matrix

Type: const Matrix*

Pointer to a Matrix object that specifies the transformation matrix to apply to each value in the text array.

[out] boundingBox

Type: RectF*

Pointer to a RectF object that receives the rectangle that bounds the string.

Return value

Type: Status

If the method succeeds, it returns Ok, which is an element of the Status enumeration.

If the method fails, it returns one of the other elements of the Status enumeration.
