mlib_GraphicsFillRectangle(3MLIB) mlib_GraphicsFillRectangle(3MLIB) NAME
mlib_GraphicsFillRectangle, mlib_GraphicsFillRectangle_8, mlib_GraphicsFillRectangle_32, mlib_GraphicsFillRectangle_X_8, mlib_GraphicsFill- Rectangle_X_32, mlib_GraphicsFillRectangle_B_8, mlib_GraphicsFillRectangle_B_32 - draw filled rectangle SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_GraphicsFillRectangle_8(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 w, mlib_s32 h, mlib_s32 c); mlib_status mlib_GraphicsFillRectangle_32(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 w, mlib_s32 h, mlib_s32 c); mlib_status mlib_GraphicsFillRectangle_X_8(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 w, mlib_s32 h, mlib_s32 c, mlib_s32 c2); mlib_status mlib_GraphicsFillRectangle_X_32(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 w, mlib_s32 h, mlib_s32 c, mlib_s32 c2); mlib_status mlib_GraphicsFillRectangle_B_8(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 w, mlib_s32 h, mlib_s32 c, mlib_s32 a); mlib_status mlib_GraphicsFillRectangle_B_32(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 w, mlib_s32 h, mlib_s32 c, mlib_s32 a); Each of the mlib_GraphicsFillRectangle_*() functions draws a filled rectangle with the upper-left corner at (x, y), width w, and height h. Each of the mlib_GraphicsFillRectangle_X_*() functions draws a filled rectangle in Xor mode as follows: data[x,y] ^= c ^ c2 Each of the mlib_GraphicsFillRectangle_B_*() functions draws a filled rectangle with alpha blending as follows: data[x,y] = (data[x,y] * (255 - a) + c * a) / 255 Each of the functions takes some of the following arguments: buffer Pointer to the image into which the function is drawing. x X coordinate of the upper-left corner of the rectangle. y Y coordinate of the upper-left corner of the rectangle. w Width of the rectangle. h Height of the rectangle. c Color used in the drawing. c2 Alternation color. a Alpha value for blending. 0 <= a <= 255. Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
