from_hdc() [1/2]

static graphics xtd::drawing::graphics::from_hdc ( intptr  hdc )

static

Creates a new xtd::drawing::graphics from the specified handle to a device context.

Parameters

hdc	Handle to a device context.

Returns

This method returns a new xtd::drawing::graphics for the specified device context.

Remarks

Even if the display device has an associated ICM color profile, GDI+ will not use that profile by default. To enable ICM for a xtd::drawing::graphics, construct the xtd::drawing::graphics from an HDC after you pass the HDC (and ICM_ON) to the SetICMMode function. Then any drawing done by the xtd::drawing::graphics will be adjusted according to the ICM profile associated with the display device. Enabling ICM will result in slower performance.

The state of the device context (mapping mode, logical unit, and the like) at the time you call xtd::drawing::graphics::from_hdc can affect rendering done by the xtd::drawing::graphics.
