Font question - sending data to an LED display
I am building an application that will support an LED display (advertising) board.
Users will be able to use my application to enter text in a number of different languages and send the data to via serial port to the processor attached to an LED display board.
The way that I am doing this is I take the string entered by the user and write it on to an image. The size of the image will correspond to the size of the LED display so that each pixel in the image can be treated as a single LED.
The problem that I am facing is that when sending data to smaller board sizes, the font that I am using does not give a clear image. For example, for a board sized 32 X 16 LED'S, the image that I generate, which might contain 1 or 2 characters, needs to 32 X 16 pixels in size. To fit a character within the 16 pixel height, I need to use a very small font size. When I send this image to the LED display, the output becomes distorted.
I have tried this with a number of different fonts but the result is the same. Also my choice of fonts is restricted by the fact that I can only use fonts that support the unicode ranges for asian languages.
Can anyone suggest a unicode font that looks good at very small sizes (16 pixels high) or if there is any other way out of this problem?
Thanks a lot in advance!
