Hi All

As usual, thanks in advance!

I wish to output certain ascii characters to a canvas but need each
one to be 64 pixels x 64 pixels using a user chosen font.

So user chooses font Arial, I then want to draw an 'A' using font
arial but the 'A' must be 64 pixels by 64 pixels.

any help much appreciated!

Hi JasonLugg,

Use the TextWidth and TextHeight functions of the canvas. Increase the
font size in a loop until the width or the height is equal or bigger
then 64.

64 pixels x 64 pixels?

Did you mean you want to stretch the the letter to a perfect square
size of 64 x 64? Proportional fonts usually won't looks good if you
make all the characters same width, especially for the characters: i,
I, l.

Arial is a proportional font, so it won't looks good if you do so. You
may consider to use monospace (non-proportional) fonts:

Old era games (DOS) usually use monospaced fonts.
