Luna::Font::IFontFile::get_glyph_bitmap_box

virtual RectI get_glyph_bitmap_box(u32 font_index, glyph_t glyph, f32 scale_x, f32 scale_y, f32 shift_x, f32 shift_y)=0

Gets the bounding box of the bitmap centered around the glyph origin.

Parameters

• in font_index

  The index of the font to query.

• in glyph

  The index of the glyph to query.

• in scale_x

  The scale factor in horizontal direction.

• in scale_y

  The scale factor in vertical direction.

• in shift_x

  The value to shift bitmap bounding box in horizontal direction in pixels.

• in shift_y

  The value to shift bitmap bounding box in vertical direction in pixels.

Remark

The location to place the bitmap top left is (left_side_bearing * scale_x + shift_x, shift_y). Note that the bitmap uses y-increases-down, but the shape uses y-increases-up, so get_glyph_bitmap_box and get_glyph_bounding_box are inverted.
