Please tell me how to draw a line of 2.3mm width on a printer? If i want to use the glLineWidth then i can specify the width in terms of number of pixels.
But how can i find the exact number of pixels that are equal to 2.3mm??. Because the resolution of the printer is different in X and Y directions and i am not sure which resolution should i take to calculate the number of pixels that are equal to 2.3 mm??
Please help. I thank you in advance.
