| #define | BMM_NO_TYPE 0 |
| Not allocated yet. |
|
| #define | BMM_LINE_ART 1 |
| 1-bit monochrome image |
|
| #define | BMM_PALETTED 2 |
| 8-bit paletted image. |
|
| #define | BMM_GRAY_8 3 |
| 8-bit grayscale bitmap. |
|
| #define | BMM_GRAY_16 4 |
| 16-bit grayscale bitmap. |
|
| #define | BMM_TRUE_16 5 |
| 16-bit true color image. |
|
| #define | BMM_TRUE_32 6 |
| 32-bit color: 8 bits each for Red, Green,
Blue, and Alpha. |
|
| #define | BMM_TRUE_64 7 |
| 64-bit color: 16 bits each for Red, Green,
Blue, and Alpha. |
|
| #define | BMM_LOGLUV_32 13 |
| This format uses a logarithmic encoding of
luminance and U' and V' in the CIE perceptively uniform space.
|
|
| #define | BMM_LOGLUV_24 14 |
| This format is similar to BMM_LOGLUV_32
except is uses smaller values to give a span of 5 order of
magnitude from 1/4096 to 16 in 1.1% luminance steps. |
|
| #define | BMM_LOGLUV_24A 15 |
| This format is similar to BMM_LOGUV_24,
except the 8 bit alpha value is kept with the 24 bit color value in
a single 32 bit word. |
|
| #define | BMM_REALPIX_32 16 |
| The "Real Pixel" format. |
|
| #define | BMM_FLOAT_RGBA_32 17 |
| 32-bit floating-point per component
(non-compressed), RGB with or without alpha |
|
| #define | BMM_FLOAT_GRAY_32 18 |
| 32-bit floating-point (non-compressed),
monochrome/grayscale |
|
| #define | BMM_TRUE_24 8 |
| 24-bit color: 8 bits each for Red, Green,
and Blue. |
|
| #define | BMM_TRUE_48 9 |
| 48-bit color: 16 bits each for Red, Green,
and Blue. |
|
| #define | BMM_YUV_422 10 |
| This is the YUV format - CCIR 601. |
|
| #define | BMM_BMP_4 11 |
| Windows BMP 16-bit color bitmap. |
|
| #define | BMM_PAD_24 12 |
| Padded 24-bit (in a 32 bit register).
|
|
| #define | BMM_FLOAT_RGB_32 19 |
| ONLY returned by the GetStoragePtr() method
of BMM_FLOAT_RGBA_32 storage, NOT an actual storage type! When
GetStoragePtr() returns this type, the data should be interpreted
as three floating-point values, corresponding to Red, Green, and
Blue (in this order). |
|
| #define | BMM_FLOAT_A_32 20 |
| ONLY returned by the GetAlphaStoragePtr()
method of BMM_FLOAT_RGBA_32 or BMM_FLOAT_GRAY_32 storage, NOT an
actual storage type! When GetStorageAlphaPtr() returns this type,
the data should be interpreted as floating-point values one value
per pixel, corresponding to Alpha. |
|
| #define BMM_NO_TYPE 0 |
Not allocated yet.
| #define BMM_LINE_ART 1 |
1-bit monochrome image
| #define BMM_PALETTED 2 |
| #define BMM_GRAY_8 3 |
8-bit grayscale bitmap.
| #define BMM_GRAY_16 4 |
16-bit grayscale bitmap.
| #define BMM_TRUE_16 5 |
16-bit true color image.
| #define BMM_TRUE_32 6 |
32-bit color: 8 bits each for Red, Green, Blue, and Alpha.
| #define BMM_TRUE_64 7 |
64-bit color: 16 bits each for Red, Green, Blue, and Alpha.
| #define BMM_LOGLUV_32 13 |
This format uses a logarithmic encoding of luminance and U' and V' in the CIE perceptively uniform space.
It spans 38 orders of magnitude from 5.43571 to 1.84467 in steps of about 0.3% luminance steps. It includes both positive and negative colors. A separate 16 bit channel is kept for alpha values.
| #define BMM_LOGLUV_24 14 |
This format is similar to BMM_LOGLUV_32 except is uses smaller values to give a span of 5 order of magnitude from 1/4096 to 16 in 1.1% luminance steps.
A separate 8 bit channel is kept for alpha values.
| #define BMM_LOGLUV_24A 15 |
This format is similar to BMM_LOGUV_24, except the 8 bit alpha value is kept with the 24 bit color value in a single 32 bit word.
| #define BMM_REALPIX_32 16 |
The "Real Pixel" format.
| #define BMM_FLOAT_RGBA_32 17 |
32-bit floating-point per component (non-compressed), RGB with or without alpha
| #define BMM_FLOAT_GRAY_32 18 |
32-bit floating-point (non-compressed), monochrome/grayscale
| #define BMM_TRUE_24 8 |
24-bit color: 8 bits each for Red, Green, and Blue.
