3.emwin5.26 (Ucgui) VS2008 2-d Graphics Library-Basic drawing "worldsing notes"

Ucgui (emWin) 2-d Graphics Library-The basic board drawing, in the basic graphics function of Ucgui, the function is still relatively full, this routine mainly uses the basic interface, the two main concept is to draw (draw) and fill (fill), the difference between the two is a hollow, Another is solid, time to note added to the distinction, another noteworthy is the drawing mode, Gui_setdrawmode (), the current emWin5.2 has two modes, one is normal drawing, the other is the way to draw the inverse.

Gui_getpixelindex () returns the color index for the given position.

?

Drawing mode

Gui_getdrawmode () returns the current drawing mode.

Gui_setdrawmode () sets the drawing mode.

?

Brush size

Gui_getpensize () returns the current brush size (in pixels).

Gui_setpensize () Sets the brush size (in pixels).

Basic drawing Routines

Gui_clearrect () fills the rectangular area with the background color.

Gui_copyrect () Duplicates a rectangular area in the display.

Gui_drawgradienth () Draws a rectangle filled with horizontal color gradients.

Gui_drawgradientv () Draws a rectangle filled with a vertical color gradient.

Gui_drawgradientroundedh () Draws a rounded rectangle filled with a horizontal color gradient.

Gui_drawgradientroundedv () Draws a rounded rectangle filled with a vertical color gradient.

Gui_drawpixel () draws a single pixel.

Gui_drawpoint () draws a point.

Gui_drawrect () draws a rectangle.

Gui_drawrectex () draws a rectangle.

Gui_drawroundedframe () Draws a rounded corner box.

Gui_drawroundedrect () draws a rounded rectangle.

Gui_fillrect () draws the filled rectangle.

Gui_fillrectex () draws the filled rectangle.

Gui_fillroundedrect () Draws a filled rounded rectangle.

Gui_invertrect () reverses the rectangular area.
