draw_image_unscaled() [1/4]

void xtd::drawing::graphics::draw_image_unscaled	(	const xtd::drawing::image &	image,
		const xtd::drawing::point &	point
	)

Draws a specified image using its original physical size at a specified location.

Parameters

image	xtd::drawing::image to draw.
point	xtd::drawing::point structure that specifies the upper-left corner of the drawn image.

Remarks

An xtd::drawing::image stores a value for pixel width and a value for horizontal resolution (dots per inch). The physical width, measured in inches, of an image is the pixel width divided by the horizontal resolution. For example, an image with a pixel width of 216 and a horizontal resolution of 72 dots per inch has a physical width of 3 inches. Similar remarks apply to pixel height and physical height.

The xtd::drawing::graphics::draw_image_unscaled method draws an image using its physical size, so the image will have its correct size in inches regardless of the resolution (dots per inch) of the display device. For example, suppose an image has a pixel width of 216 and a horizontal resolution of 72 dots per inch. If you call xtd::drawing::graphics::draw_image_unscaled to draw that image on a device that has a resolution of 96 dots per inch, the pixel width of the rendered image will be (216/72)*96 = 288.
