glyphs

2010-07-07 Thread august 

Hi,
I'm a newbie to pango low-level functions and am trying to learn how
to use pango_itemize, pango_break, and pango_shape properly. 

Given an item from pango_itemize, I do:


PangoGlyphString *glyphs = pango_glyph_string_new();
pango_glyph_string_set_size(glyphs, item-num_chars);
pango_shape(text+item-offset, item-length, item-analysis, glyphs);

printf(number of glyphs: %d \n, glyphs-num_glyphs);

for (int j=1;j glyphs-num_glyphs ;j++){
// crashes here
printf(#%d, guint32 glyph=%d\n, j, glyphs[j].glyphs-glyph );
}


What am I doing wrong? 


thanks -august.

it figures that I have been staring at this for a few hours already and
notice my mistake right after I send for help to the list.

It should be:
printf(#%d, guint32 glyph=%d\n, j, glyphs-glyphs[j].glyph );


sorry for the noise.

But, if anyone has a link to some readable example code using
pango_itemize, pango_break, and pango_shape, I'd really appreciate it.
I cannot find anything online.

iterate through a layout by char or word?

2010-07-07 Thread august 


Is there any way to iterate through a PangoyLayout by character or word?

Is there a way to iterate by word and then show it using cairo?



I can do something similar with pango_itemize, pango_break, and
pango_shape.   But, I can't seem to do anything with the resulting
PangoGlyphString  that I get.

I can do pango_cairo_show_glyph_string(), but I want to just show a word
or character.  Is there something like
pango_cairo_show_glyph_string_range()?


I can do pango_glyph_string_copy(), but cant do anything like strncpy
where I can just get a segment of that PangoGlyphString.  


Any tips would be greatly appreciated.


thanks -august.
