SuperRect: draw a rounded corner rectangle `[ 60 ]`

Description

Draws a rounded corners rectangle with current draw and fill colors and current line width which ought to have been previously specified by respectively SetDrawColor(), SetFillColor() and SetLineWidth(). Radius of each one of the four corners ought to be specified. It takes 9 parameters described below:

X ⇒ Float number which specifies abscissa of top left corner
Y ⇒ Float number which specifies ordinate of top left corner
W ⇒ Float number which specifies Rectangle width
H ⇒ Float number which specifies Rectangle Height
String which specifies rendering mode: may be
- "D" for Draw,
- "F" for Fill,
- "DF" or "FD" for Draw and Fill
RTL ⇒ Float number which specifies radius of top left corner
RTR ⇒ Float number which specifies radius of top right corner
RBR ⇒ Float number which specifies radius of bottom right corner
RBL ⇒ Float number which specifies radius of bottom left corner

C calling syntax

void SuperRect (float x, float y, float w, float h, char *style, float rtl, float rtr, float rbr, float rbl);

Cobol calling syntax

Call "SuperRect" using by value X,Y,W,H,M,RTL,RTR,RBR,RBL.

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
