drawing

Definition

All needed for drawing something.

Remarks
A xtd::drawing::graphics class is create from xtd::forms::control::create_graphics or xtd::forms::screen::create_graphics or xtd::drawing::image::create_graphics.
And also when xtd::forms::control::paint event is sended, the xtd::forms::paint_event_args contains a xtd::drawing::graphics associate to the control event paint.

Classes

class  xtd::drawing::bitmap
 Encapsulates a GDI+ bitmap, which consists of the pixel data for a graphics image and its attributes. A bitmap is an object used to work with images defined by pixel data. More...
 
class  xtd::drawing::brushes
 brushes for all the standard colors. This class cannot be inherited. More...
 
class  xtd::drawing::color
 Represents an ARGB (alpha, red, green, blue) color. More...
 
class  xtd::drawing::colors
 colors for all the standard colors. This class cannot be inherited. More...
 
class  xtd::drawing::drawing2d::hatch_brush
 Defines a rectangular brush with a hatch style, a foreground color, and a background color. This class cannot be inherited. More...

Function Documentation

◆ create_graphics() [1/3]

static drawing::graphics xtd::forms::screen::create_graphics ( )
static

#include <xtd.forms/include/xtd/forms/screen.h>

Creates the xtd::drawing::graphics for the screen.

Returns
A xtd::drawing::graphics for the screen.

◆ create_graphics() [2/3]

graphics xtd::drawing::image::create_graphics ( )
inline

#include <xtd.drawing/include/xtd/drawing/image.h>

Creates the xtd::drawing::graphics for the image.

Returns
A xtd::drawing::graphics for the image.

◆ create_graphics() [3/3]

drawing::graphics xtd::forms::control::create_graphics ( ) const

#include <xtd.forms/include/xtd/forms/control.h>

Creates the xtd::drawing::graphics for the control.

Returns
A xtd::drawing::graphics for the control.
Remarks
The graphics object that you retrieve through the create_graphics method should not normally be retained after the current Windows message has been processed, because anything painted with that object will be erased with the next WM_PAINT message. Therefore you cannot cache the graphics object for reuse, except to use non-visual methods like xtd::drawing::graphics::measure_string. Instead, you must call create_graphics every time that you want to use the graphics object.
