Re: [ft] 26.6 format

[samaram s]

Thanks a lot for the quick reply.
I have one more question,
Is there any API which gives the 8bit hex representation of  array of bytes for a given glyph?I mean,
For a Glyph F, i can represent array of bytes as {78,40,40,40,F0,.........}
I would like to know whether there is any API which gives the 8 bit representation of  a given glyph with the given ttf font file.

78  .****... (78h)
40  .*......(40H)
40  .*......
40  .*......
F0  ****....
40  .*......
40  .*......
40  .*......
40  .*......


Can anyone please throw ideas ,it is a great help.

Thankful to all

It's a fixed-point value. Another common format is 16.16. You can read more about it at http://en.wikipedia.org/wiki/Fixed-point_arithmetic and there are other resources around on the web. Probably the easiest way to think about it is a 26.6 number is actually 1/64th. So, "1" means 1/64, "32" means 32/64 = .5, "64" is 64/64 = 1, etc. It is 1/64 because 6 bits are being used for the decimal portion (2^6).

In a 32 bit word, 26 bits are used to represent the pixel coordinate and 6 represent the sub-pixel position.
