Re: character to bitmap conversion...

[Tomi Manninen <tpm prkele tky hut fi>]

Hi,

And thanks for the answer. Yes, you certainly are right. This application
will involve specially designed fonts and only certain sizes will be
useable. However I would like to make it as flexible as possible and leave
the decision whether a certain font/size can be used to the user.

The application I am writing is an implementation of the Hellschreiber
communication system (named after the inventor Rudolph Hell and also
german for "bright writer") that dates back to the twenties. Basically it
is a crude form of telefax. In case you are interested see
<http://www.qsl.net/zl1bpu/FUZZY/Feld.html>.

I already have a working hack that goes like this: I create a small
pixmap and draw the character on it with gdk_draw_text(). Then I make a
GdkImage from it with gdk_image_get(). This image I scan with 
gdk_image_get_pixel().

That works but it is _ugly_. Also if I have understood the process 
involves transfering stuff to the server side and back (?). That is 
something to be avoided I think...

So now I ask, is there a way to do this a bit more cleanly and 
efficiently?
