I am trying to create a board layout with roughly 4 inch (10cm) high, italic words, using dual rows of 5mm LED's. (The letters in the words are static, similar to the image below) I'd like the letters to be non-blocky, i.e. it would be good if a "P" had rounded corners on the right.
My first thought was to use the text function built into P-cad 2004 to put the text on silkscreen and then I could arrange the LED's by hand over the text. But, the maximum text size in Pcad is 1 inch high. Even if I could get the text on the silkscreen, I'm not sure placing the LED's by hand would be evenly spaced. Altium forums have not been any help.
My ideal solution would be to find a program that would scan a bitmap of the phrase, ask for LED spacing, and then output the X and Y coordinates of each LED. Short of making something like this myself, is there a better way to place the LED's? (this is meant as a general PCB layout question, not specific to P-cad)
Thanks,
Matt M.

A lot of PCB design packages will let you import a monochrome bitmap or .TIFF file to the silkscreen layer. Once all the LEDs are placed remove the silkscreen.

Or print it in a large font on graph paper, using a PC. For you young ones, graph paper is paper with a faint grid of horizontal and vertical rows pre-printed on it. It was used, in the "old days", to hand draw graphs... in the pre-PC era :)

The point being, you then measure the (X,Y) coordinates on the graph paper yourself. Every vertex becomes an LED, or whatever.
