Spaces don't maintain character width #48

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. u8g_drawStr(x,y,"12 34");
2. u8g_drawStr(x,y+dy,"56  7");

What is the expected output? What do you see instead?
I expect to see the 4 and 7 line up. Instead the 7 is 2 pixels off (to the 
left).

What version of the product are you using? On what operating system?
I'm on Windows 7, using arduino-0022, and v0.13 of u8glib.

Please provide any additional information below.

I'm sorry. I completely forgot to mention which font I'm using. I'm using the 
orgdot fixed v01 (u8g_font_fixed_v0).

Ok. So I think this issue is possibly a relic of the font itself. I made/built 
the fixed_v0.bdf and checked the DWIDTH parameter of the space character. It 
turns out it isn't the same as the other characters. 

In any case, did you mean to mix the upper/lower nibbles for the data size and 
DWIDTH parameters? It was annoying trying to keep that in mind. Otherwise I 
think this isn't actually your problem.

Thanks for the bug report.
I have investigated the fixed_v0. The font auther has indeed specified, that 
the space has a width of 4 pixel, while all other chars have 6 pixel width. So 
you will see an offest of 2 pixel. So from my perspective this is not a bug. 
You could use the monospaced fonts 6x10 or 6x12, which have a space of the same 
width as the other characters. 

Is it ok to close this issue?

oh, was working in parallel on this issue :-)

Yes, it is a font issue. There is "DWIDTH 4 0" for space and "DWIDTH 6 0" for 
other chars.

So I wrote/modified a simple draw circle routine based on the midpoint cirlce 
algorithm ( http://en.wikipedia.org/wiki/Midpoint_circle_algorithm ). Do I need 
to be added as a contributor or can I commit changes myself?
