Function Documentation

oslDrawLine()

void oslDrawLine ( int x0, int y0, int x1, int y1, OSL_COLOR color )

extern

Draws a line from (x0, y0) to (x1, y1).

This function draws a line on the screen from the starting point (x0, y0) to the ending point (x1, y1) using the specified color.

Parameters

x0	The x-coordinate of the start point of the line.
y0	The y-coordinate of the start point of the line.
x1	The x-coordinate of the end point of the line.
y1	The y-coordinate of the end point of the line.
color	The color of the line.

oslDrawRect()

void oslDrawRect ( int x0, int y0, int x1, int y1, OSL_COLOR color )

extern

Draws an empty rectangle from (x0, y0) to (x1, y1).

This function draws the outline of a rectangle on the screen with the top-left corner at (x0, y0) and the bottom-right corner at (x1, y1). The rectangle is drawn with the specified color.

Parameters

x0	The x-coordinate of the top-left corner of the rectangle.
y0	The y-coordinate of the top-left corner of the rectangle.
x1	The x-coordinate of the bottom-right corner of the rectangle.
y1	The y-coordinate of the bottom-right corner of the rectangle.
color	The color of the rectangle outline.

oslDrawFillRect()

void oslDrawFillRect ( int x0, int y0, int x1, int y1, OSL_COLOR color )

extern

Draws a filled rectangle from (x0, y0) to (x1, y1).

This function draws a filled rectangle on the screen with the top-left corner at (x0, y0) and the bottom-right corner at (x1, y1). The rectangle is filled with the specified color.

Parameters

x0	The x-coordinate of the top-left corner of the rectangle.
y0	The y-coordinate of the top-left corner of the rectangle.
x1	The x-coordinate of the bottom-right corner of the rectangle.
y1	The y-coordinate of the bottom-right corner of the rectangle.
color	The color used to fill the rectangle.

oslDrawGradientRect()

void oslDrawGradientRect ( int x0, int y0, int x1, int y1, OSL_COLOR c1, OSL_COLOR c2, OSL_COLOR c3, OSL_COLOR c4 )

extern

Draws a gradient rectangle from (x0, y0) to (x1, y1).

This function draws a rectangle on the screen with a gradient color effect. The gradient transitions from one color to another across the rectangle. The colors are applied as follows:

• c1 is used for the top-left corner.
• c2 is used for the top-right corner.
• c3 is used for the bottom-left corner.
• c4 is used for the bottom-right corner.

Parameters

x0	The x-coordinate of the top-left corner of the rectangle.
y0	The y-coordinate of the top-left corner of the rectangle.
x1	The x-coordinate of the bottom-right corner of the rectangle.
y1	The y-coordinate of the bottom-right corner of the rectangle.
c1	The color of the top-left corner.
c2	The color of the top-right corner.
c3	The color of the bottom-left corner.
c4	The color of the bottom-right corner.
