FS#4836 - Font scaling in wps

This is support for simple font scaling on the wps screen.
I’ve posted some screenshots in the forum: http://forums.rockbox.org/index.php?topic=2856.0

By simple font scaling, I mean that the font characters are just increased by a factor of 2 or 3 (or more). No anti-aliasing is done, so most of the font’s will look pixelated when displayed larger than their native size.

I’ve only tested this on the H120/140 + remote, so this only patches the lcd code for that platform. I only changed generic code for the lcds, hence, I think the code should be easily portable to the other targets.

To use font scaling on the wps screen, use the syntax %h2 or %h3 to increase the font size by a factor of 2 or 3. This affects all the text on that line (you can’t scale just part of the line). IMPORTANT: if you use %h2, leave the next line empty in the wps file. If you use %h3, leave the next 2 lines blank. (This is necessary because the wps and lcd code is line-based.) Also, you can scroll scaled text.

I’ll be the first to admit that scaling most of the fonts does not produce a nice effect. However, the “snap” font does look good (see the screen shots). I also don’t know if (or how much) the font scaling affects performance.

Let me know what you think.

waiting for multi-font….

I think it would be better if all fonts were anti-aliased anyway - or certainly if the platform supports it and the user requests the feature enabled. As I am not much of a C coder and have only a limited knowledge of the structure of RockBox, Im not sure where changes would need to occur to make this possible. I assume that the Graphics API has some kind of text rendering function. Could it be possible that an anti-aliasing algorithm could be introduced here? It would be nice if TrueType font rendering could be introduced. How much of a performance hit would this be? Perhaps as an intermediate step, rasterized fonts with pre-rendered anti-aliasing could be introduced (?) This would give theme developers the freedom to create some pretty cool Amiga-like fonts…

Thanks for your work on this stuff!

doesnt work anymore..

wouldnt it be easier to allow multiple fonts in one wps?
like preloading a small and a large font to show all the “unnecessary” detail in the small font (codex, size etc.) and the important info (song title) in a bigger font?
