not drawing the complete letter

[Fahad-Alsaidi]

When I try to draw letter "H" using the attached font, it appears cut from the end.

I don't know where is the problem come from? harfbuzz or cairo ? so I hesitate to report it in main harfbuzz repository.

the font: Edw.zip

HarfBuzz doesn't draw anything.

Whithout checking the font, the glyph might have a -ve left side bearing and the code that is creating Cairo surface is only taking the glyph advance into account when setting the width.

[khaledhosny]

This code does not take glyph extents into account.

harfbuzz-tutorial/hello-harfbuzz-freetype.c

Lines 102 to 110 in d09b205

	for (unsigned int i = 0; i < len; i++)
	{
	width += pos[i].x_advance / 64.;
	height -= pos[i].y_advance / 64.;
	}
	if (HB_DIRECTION_IS_HORIZONTAL (hb_buffer_get_direction(hb_buffer)))
	height += FONT_SIZE;
	else
	width += FONT_SIZE;

I meant right side bearing.

[behdad]

That's actually expected. hb-view etc work the same way. User should add more margin if needed.

[Fahad-Alsaidi]

@khaledhosny how I can add right side bearing automatically?

Use hb_font_get_glyph_extents() to get the glyph bounding box and use this to calculate the ”ink” extents of the line.
