[Bug-ocrad] bad parameter building a Rectangle

[Tilman Hausherr]

Hello Antonio,

I get this:

bad parameter building a Rectangle
l = 742, t = 691, r = 741, b = 706

It happens both in Visual C++ and with gcc.

In Textline::recognize2(), in the segment
  // separate merged characters recognized by recognize1
in the loop
  for( int g = 1; g < c.guesses(); ++g )
the error happens at
  Rectangle re( left, b.top(), c.guess( g ).value, b.bottom() );

g is 2
c.gv[0] code 0, value 738
c.gv[1] code 102, value 741
c.gv[2] code 105, value 741

Btw, when g is 1, these are the values:

l = 738, t = 691, r = 741, b = 706

so when you do 
  left = re.right() + 1;
at the end of the loop, left gets too high.

The bitmap of blob b has 16 rows. The rows are all 0,0,0,1.

I can't send you the image, sadly, because as soon as I remove anything
meaningful, the error no longer happens. But I can offer you more trace
output if needed.
