The following constants, defined in Gdipluspixelformats.h, specify various pixel formats used in bitmaps.
| Constant | Description |
|---|---|
|
Specifies that the format is 1 bit per pixel, indexed. |
|
Specifies that the format is 4 bits per pixel, indexed. |
|
Specifies that the format is 8 bits per pixel, indexed. |
|
Specifies that the format is 16 bits per pixel; 1 bit is used for the alpha component, and 5 bits each are used for the red, green, and blue components. |
|
Specifies that the format is 16 bits per pixel, grayscale. |
|
Specifies that the format is 16 bits per pixel; 5 bits each are used for the red, green, and blue components. The remaining bit is not used. |
|
Specifies that the format is 16 bits per pixel; 5 bits are used for the red component, 6 bits are used for the green component, and 5 bits are used for the blue component. |
|
Specifies that the format is 24 bits per pixel; 8 bits each are used for the red, green, and blue components. |
|
Specifies that the format is 32 bits per pixel; 8 bits each are used for the alpha, red, green, and blue components. |
|
Specifies that the format is 32 bits per pixel; 8 bits each are used for the alpha, red, green, and blue components. The red, green, and blue components are premultiplied according to the alpha component. |
|
Specifies that the format is 32 bits per pixel; 8 bits each are used for the red, green, and blue components. The remaining 8 bits are not used. |
|
Specifies that the format is 48 bits per pixel; 16 bits each are used for the red, green, and blue components. |
|
Specifies that the format is 64 bits per pixel; 16 bits each are used for the alpha, red, green, and blue components. |
|
Specifies that the format is 64 bits per pixel; 16 bits each are used for the alpha, red, green, and blue components. The red, green, and blue components are premultiplied according to the alpha component. |
Remarks
PixelFormat48bppRGB, PixelFormat64bppARGB, and PixelFormat64bppPARGB use 16 bits per color component (channel). Windows GDI+ version 1.0 can read 16-bits-per-channel images, but such images are converted to an 8-bits-per-channel format for processing, displaying, and saving.
