[PATCH v2 1/7] gdi32: Add a helper function to get the transform matrices.
Signed-off-by: Byeongsik Jeon <bsjeon(a)hanmail.net> --- Each helper function can be further refactored, but at this point, it has kept the existing code. In my personal git branch, I am modifying other issues, and these structural change seems appropriate. I will send patches that actually fix metric problems separately. dlls/gdi32/freetype.c | 234 ++++++++++++++++++++++-------------------- 1 file changed, 125 insertions(+), 109 deletions(-) diff --git a/dlls/gdi32/freetype.c b/dlls/gdi32/freetype.c index c38108eece..a522bcaba6 100644 --- a/dlls/gdi32/freetype.c +++ b/dlls/gdi32/freetype.c @@ -6588,6 +6588,129 @@ static inline FT_Vector normalize_vector(FT_Vector *vec) return out;

I'm not sure inverting the switch order between requested format and loaded format makes it any better, though adding the helpers is good. I'd suggest keeping the original switch but adding get_mono_glyph_bitmap() for GGO_BITMAP get_antialias_glyph_bitmap() for GGO_GRAY*_BITMAP get_subpixel_glyph_bitmap() for the subpixel formats. Also, please align the cases with the switch.

Yes. It's absolutely correct. I thought about this possibility, but I wanted to leave it as a different issue. So I wrote 'slightly logic change'. Of course, it is my fault that I did not make any further comments. To deal with this, I need to create a real test case and investigate the behavior of the native Windows. I have a variety of other issues besides this. In the process of resolving an issue, another issue is revealed. So when I deal with them together, patch issues of various topics are mixed up. Then Huw's patch review becomes difficult, and my patch process will also take a long time. This patch is still lacking, but it is slightly better than it is now. Thank you.

Yes. It's absolutely correct.
I looked at the behavior on Windows with a test font that manipulated the OS/2 table(Panose, AvgCharWidth). It didn't work as I thought. IMO, Windows seems to be doing something related to the following document. Surprisingly, Wine already has the scripts needed for conversion, so I can work easily. https://www.unicode.org/Public/11.0/udd/EasasianWidth.txt This is a temporary patch. Please review if possible. It is also good to post more improved patch directly. Thank you.

I agree with that Windows uses some sort of fullwidth character table, but I'm not sure about EasAsianWidth.txt. At least, there are two issues, 1. We can't get an Unicode code point when GetGlyphOutline function called with GGO_GLYPH_INDEX flag. 2. There are ambiguous width characters. For instance, is U+20AC a fullwidth character or a halfwidth one? By the way, when I tested with Gulim on Windows, I got 19 px as gmCellIncX value at 19 ppem for U+C640 (see attachment for details). Gulium shares the embedded bitmap with GuliumChe. So, why don't you fix up base_advance when using embedded bitmaps? By doing so, the advance will be 19 (not 18) before calculating fixed_pitch_full. And, we don't have to update the formula. Akihiro Sagawa
I'm late. I'm sorry. Because of my personal situation, I had to be in a network-disconnected environment for the last few days. Akihiro Sagawa wrote:

It's a good point. This is the similar case as Tategaki. ---- In get_glyph_outline(), TODO: Window also turns off tategaki for glyphs passed in by index if their unicode code points fall outside of the range that is rotated. ---- I assume the solution will be similar.
2. There are ambiguous width characters. For instance, is U+20AC a fullwidth character or a halfwidth one?
In my test, Type 'A', 'F' and 'W' of EastAsianWidth.txt were full-length characters. However, I have not yet examined the entire code area. This may depend on Windows locale. Also, Unicode versions that are supported by each version of Windows may differ.
By the way, when I tested with Gulim on Windows, I got 19 px as gmCellIncX value at 19 ppem for U+C640 (see attachment for details). Gulium shares the embedded bitmap with GuliumChe. So, why don't you fix up base_advance when using embedded bitmaps? By doing so, the advance will be 19 (not 18) before calculating fixed_pitch_full. And, we don't have to update the formula.
This is not applicable. This is a special case for the 'ttc' font file. Because Windows built-in fonts are well-adjusted fonts, it is difficult to figure out exactly what Windows is doing. I think we can test this with fonts that manipulate the AveCharWidth value. Because of other issues, it would have to be delayed later to investigate this. Thank you.
