Re: [ft] FT_Outline_Render makes different bitmaps in 32-bit and 64-bit programs?

[suzuki toshiya]

Hi,

Since 2.3.8? I'm really interested in, because I had committed
many changes for 16-bit/64-bit platforms between 2.3.9 and 2.3.10.
In your observation, 2.3.8 is ok but 2.3.9 is not ok?
Or, 2.3.7 is ok but 2.3.8 is not ok? 

Regards,
mpsuzuki

> A "good" bitmap is produced when running as a 64-bit program (sizeof(
long) = 8). A "bad" bitmap is produced when running as a 32-bit program 
(sizeof(long) = 4). The most noticeable difference between the bitmaps 
is that the bad bitmap has one row that is black almost to the left edge;
 it starts "7f ff ff ff ff ff ff ...". In the good bitmap, all the rows 
start "00 00 00 00 00 00 ...". There are also some smaller differences 
in the lower right edge of the glyph.

ftraster.c, when Draw_Sweep() calls Sort(&draw_right), the 64-bit 
version has current->X = 391953, while the 32-bit version has current->X 
= 514193. This becomes the value of x2 ( = P_Right->X) back in Draw_

linking with it, and also by including some Freetype source files 
directly in the project. Both of those ways I tested both 32-bit and 64-
bit versions, so there were really four tests on Mac OS, plus a fifth 
test on Windows 7; but on Windows 7 I only tested a 32-bit version with 
the source files included.)
