Member Function Documentation

DrawImage() [1/4]

static void DrawImage ( this Graphics dc, Image img, HighBitScaleMode mode )

static

Draw a Image object into a Graphics object. Target rectangle is defined by the image's extent.

Parameters

dc	Graphics object to paint to
img	Image to paint
mode	Treatment for images with more than 8 bits per pixel

Exceptions

ArgumentNullException

If dc is null

DrawImage() [2/4]

static void DrawImage ( this Graphics dc, Image img, Rect sourceRect, Rect targetRect, HighBitScaleMode mode )

static

Draw a Image object into a Graphics object.

Parameters

dc	Graphics object to paint to
img	Image to paint
sourceRect	Subsection of the image to paint
targetRect	Rectangle in the target dc to paint to
mode	Treatment for images with more than 8 bits per pixel

Exceptions

ArgumentNullException

If dc is null

DrawImage() [3/4]

static void DrawImage ( this Graphics dc, Image img, Rect sourceRect, Rect targetRect, PlaneConfiguration planes, double gain, int offset, HighBitScaleMode mode )

static

Draw a Image object into a Graphics object.

Parameters

dc	Graphics object to paint to
img	Image to paint
sourceRect	Subsection of the image to paint
targetRect	Rectangle in the target dc to paint to
planes	Plane configuration to use
gain	Gain to apply
offset	Offset to apply
mode	Treatment for images with more than 8 bits per pixel. Note that setting this mode to HighbitScaleMode.ViewPort cause the function to ignore the gain and offset setting.

Exceptions

ArgumentNullException	If dc is null or img is null
ObjectDisposedException	If the img has already been disposed

DrawImage() [4/4]

static void DrawImage ( this Graphics dc, Image img, Rect targetRect, HighBitScaleMode mode )

static

Draw a Image object into a Graphics object.

Parameters

dc	Graphics object to paint to
img	Image to paint
targetRect	Rectangle in the target dc to paint to
mode	Treatment for images with more than 8 bits per pixel

Exceptions

ArgumentNullException

If dc is null
