Implement Option to Change Font

[mariobehling]

Currently there is only one standard font implemented. Please implement an option to change the font.

@mariobehling this is not possible as of now, we need to have some extra pixels in the badge to morph our letters

[adityastic]

@mariobehling @iamareebjamal please give me an update

[mariobehling]

@adityastic This should be possible. It does not depend on the font.

[adityastic]

@mariobehling we are talking about the font we send to the device or the font in our application?

[iamareebjamal]

We send bitmap to pixel. Where do we send the font?

[adityastic]

@iamareebjamal yes, we created hexadecimals of every character, then we convert the input string into characters and fetch the respective hexadecimal for the character. We are not sending the font

[adityastic]

By sending the font, I meant the saved hexadecimal codes for every character

[iamareebjamal]

Nobody is talking about sending the font. We're talking about converting the font chars to bitmaps

[fcartegnie]

That's underestimating work. There's no "magic" way to create bitmap fonts.
Either you rasterize the vector/truetype font (on 1bpp that's really bad) which will look usually bad compared to a hand written bitmap.
Or you use a Unicode Bitmap font, but I doubt you'll find a matching height and that will grow the app.

What about an option to use BDF or PCF bitmap fonts?

I've used them before when driving LEDs.
