Defined in FT_IMAGE_H (freetype/ftimage.h).
|
An enumeration type used to describe the format of pixels in a given bitmap. Note that additional formats may be added in the future.
|
values |
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.
|
FT_PIXEL_MODE_BGRA |
An image with four 8-bit channels per pixel, representing a color image (such as emoticons) with alpha channel. For each pixel, the format is BGRA, which means, the blue channel comes first in memory. The color channels are pre-multiplied and in the sRGB colorspace. For example, full red at half-translucent opacity will be represented as ‘00,00,80,80’, not ‘00,00,FF,80’. See also FT_LOAD_COLOR.
