Thank you for your quick response.
I'm using "SharpFont" library from NuGet in this way:
LibFace.LoadGlyph(glypgIndex, LoadFlags.Default | hintingFlag, LoadTarget.Normal);
LibFace.Glyph.RenderGlyph(RenderMode.Normal);
// Get a bitmap that .Net can draw
var ftbmp = LibFace.Glyph.Bitmap;
if ((ftbmp.Width != 0) && (ftbmp.Rows != 0))
{
// Normal Glyph
var bmp = ftbmp.ToGdipBitmap(GlyphColor);
}
I don't use this flag "LoadFlags.VerticalLayout" (0x000010)
"LoadFlags.VerticalLayout" flag from SharpFont is "FT_LOAD_VERTICAL_LAYOUT " from FreeType.
But when the ttf file used by me contains both metrics inside ("hmtx" and "vmtx" tables) somehow the FreeType "prefers" to read data from "vmtx" table in order to create the glyphs.
Or can I set explicitly to use a Horizontal Layout?
Of course I'm aware that the problem can come from my code or from my ttf file used or from SharpFont, but I would ask you if you know a bug in this area (in FreeType)
Please see also my attached picture.
Thank you,

I don't understand what you mean. Can you repeat the issue with one
of the FreeType demo programs?

Of course. If you don't use the FT_LOAD_VERTICAL_LAYOUT flag with
FT_Load_Glyph, you are using horizontal metrics.
