Re: [fltk.development] [RFE] STR #2941: RFE: fl_text_extents(): supportmultiple lines
Hm, doesn't fl_measure() do all this already? - chris Would be nice if an alternate version of fl_text_extents() were available that could handle crlfs in the string. Probably wouldn't be too hard; just need to break the one string into separate lines, then run the existing fl_text_extents() on each line. The tricky part would be to take into account FL_ALIGN_* flags..

No, fl_measure() measures typographical area,
whereas fl_text_extents() measures the 'inking area'.
These are very different.
See the test/unittests program, text rendering test for a comparison
of the two functions (red vs green boxes)
In particular how the two functions calculate differently the bounding
region
for the characters ('), (-), and (_); fl_measure() returns the x,y and
height
for those characters, whereas fl_text_extents() does not.
