freetypy.PIXEL_MODE¶

class freetypy.PIXEL_MODE¶

Constants related to the pixel mode of bitmaps.

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.
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 Bitmap structure (it generally is 256).
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.
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.
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 RENDER_MODE.LCD. On many freetype builds, this functionality will be disabled due to patent restrictions, in which case the resulting bitmap will be grayscale.
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 RENDER_MODE.LCD_V. On many freetype builds, this functionality will be disabled due to patent restrictions, in which case the resulting bitmap will be grayscale.
