SetLineWidth: Set Line thickness `[ 23 ]`

Description

Set the width of the subsequent lines to be drawn. This setting impacts the way lines are drawn by the following functions : Cell(), Line(), Rect(), SuperRect(), Elipse(), Polygon(), Sector().

It takes a single parameter which is a float number representing the line thickness to be applied in subsequent drawing functions

C calling syntax

void SetLineWidth (float lw)

Cobol calling syntax

CALL "SetLineWidth" using by value lw.

C sample code

#include   "fpdf.h"

static char   f_ini ??(??) = ??< "ini??/??/demofpdf.ini" ??>;
static char   f_out ??(??) = ??< "pdf??/??/demo_b.pdf" ??>;

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
