FT_PIXEL_MODES¶
An enumeration type that lists the render modes supported by FreeType 2. Each mode corresponds to a specific type of scanline conversion performed on the outline.
-
FT_PIXEL_MODE_NONE
¶ Value 0 is reserved.
-
FT_PIXEL_MODE_MONO
¶ A monochrome bitmap, using 1 bit per pixel. Note that pixels are stored in most-significant order (MSB), which means that the left-most pixel in a byte has value 128.
-
FT_PIXEL_MODE_GRAY
¶ An 8-bit bitmap, generally used to represent anti-aliased glyph images. Each pixel is stored in one byte. Note that the number of ‘gray’ levels is stored in the ‘num_grays’ field of the FT_Bitmap structure (it generally is 256).
-
FT_PIXEL_MODE_GRAY2
¶ A 2-bit per pixel bitmap, used to represent embedded anti-aliased bitmaps in font files according to the OpenType specification. We haven’t found a single font using this format, however.
-
FT_PIXEL_MODE_GRAY4
¶ A 4-bit per pixel bitmap, representing embedded anti-aliased bitmaps in font files according to the OpenType specification. We haven’t found a single font using this format, however.
-
FT_PIXEL_MODE_LCD
¶ An 8-bit bitmap, representing RGB or BGR decimated glyph images used for display on LCD displays; the bitmap is three times wider than the original glyph image. See also FT_RENDER_MODE_LCD.
-
FT_PIXEL_MODE_LCD_V
¶ An 8-bit bitmap, representing RGB or BGR decimated glyph images used for display on rotated LCD displays; the bitmap is three times taller than the original glyph image. See also FT_RENDER_MODE_LCD_V.
