SetDrawColor: Set lines color `[ 19 ]`

Description

Set color of lines to be drawn with functions Cell(), Line(), Rect(), SuperRect(), Elipse(), Circle(), Polygon(), Sector(). This function takes 3 integer parameters:

Red ⇒ a value between 0 and 255
Green ⇒ a value between 0 and 255
Blue ⇒ a value between 0 and 255

Developper Notes:

If an integer number is greater than 255, it is logically "ANDED" with 0xff.
There are 24 millions combinations which may be obtained from black (0,0,0) upto white (255,255,255).
If one of these 3 numbers is negative, it will be automatically replaced with its corresponding value set by means of function SetCustColors().

C calling syntax

void SetDrawColor (int r, int,g int b)

Cobol calling syntax

Description of sample code

This piece of code creates an elementary rosette within a rounded corners rectangle, illustrating the use of following functions.
- SetLineWidth()  -->  Set the width of lines to be drawn
- SetDrawColor()  -->  Set the color of lines to be drawn
- SetFillColor()  -->  Set the color of area to be filled
- SuperRect()     -->  Draw a rounded corner rectangle
- Ellipse()       -->  Draw an ellipse
- Rotate()        -->  Rotate the XY coordinates of a given angle around a point
