Defines |
|
| #define | MAP_NOFLAGS ((DWORD)0) |
| The bitmap has none of the characteristics
below. |
|
| #define | MAP_READY ((DWORD)(1<<0)) |
| This bitmap has had memory allocated to it,
or is accessible directly. |
|
| #define | MAP_HAS_ALPHA ((DWORD)(1<<1)) |
| This flag can be checked from a BitmapInfo instance
(bi.Flags()&MAP_HAS_ALPHA)), but not from a Bitmap instance (bmap->Flags() &
MAP_HAS_ALPHA). |
|
| #define | MAP_ALPHA_PREMULTIPLIED ((DWORD)(1<<2)) |
| The bitmap has pre-multiplied alpha.
|
|
| #define | MAP_PALETTED ((DWORD)(1<<3)) |
| The bitmap uses a palette (not true color).
|
|
| #define | MAP_FRAME_SYSTEM_LOCKED ((DWORD)(1<<4)) |
| This flag is no longer used. |
|
| #define | MAP_DITHERED ((DWORD)(1<<5)) |
| The bitmap is dithered. |
|
| #define | MAP_FLIPPED ((DWORD)(1<<6)) |
| The bitmap is flipped horizontally. |
|
| #define | MAP_INVERTED ((DWORD)(1<<7)) |
| The bitmap is flipped vertically. |
|
| #define | MAP_USE_SCALE_COLORS ((DWORD)(1<<10)) |
| Scale colors when high dynamic range values
are out of gamut. |
|
| #define | MAP_PROXY ((DWORD)(1<<11)) |
| When the proxy flag is set, the BitmapInfo is called a proxy
info. |
|
| #define | MAP_PROXYREQUEST ((DWORD)(1<<12)) |
| When the proxy request flag is set, the
BitmapInfo is
called a request info. |

These flag bits describe properites of the bitmap.
| #define MAP_NOFLAGS ((DWORD)0) |
The bitmap has none of the characteristics below.
| #define MAP_READY ((DWORD)(1<<0)) |
This bitmap has had memory allocated to it, or is accessible directly.
| #define MAP_HAS_ALPHA ((DWORD)(1<<1)) |
This flag can be checked from a BitmapInfo instance (bi.Flags()&MAP_HAS_ALPHA)), but not from a Bitmap instance (bmap->Flags() & MAP_HAS_ALPHA).
Therefore if you have a Bitmap, use the Bitmap's HasAlpha() method to see if the map has an alpha channel. The bitmap has an alpha channel.
| #define MAP_ALPHA_PREMULTIPLIED ((DWORD)(1<<2)) |
The bitmap has pre-multiplied alpha.
| #define MAP_PALETTED ((DWORD)(1<<3)) |
The bitmap uses a palette (not true color).
| #define MAP_FRAME_SYSTEM_LOCKED ((DWORD)(1<<4)) |
This flag is no longer used.
| #define MAP_DITHERED ((DWORD)(1<<5)) |
The bitmap is dithered.
| #define MAP_FLIPPED ((DWORD)(1<<6)) |
The bitmap is flipped horizontally.
| #define MAP_INVERTED ((DWORD)(1<<7)) |
The bitmap is flipped vertically.
| #define MAP_USE_SCALE_COLORS ((DWORD)(1<<10)) |
Scale colors when high dynamic range values are out of gamut.
| #define MAP_PROXY ((DWORD)(1<<11)) |
When the proxy flag is set, the BitmapInfo is called a proxy info.
The info for the proxy's original subject bitmap is called the subject info. The subject info is available from the proxy info via BitmapInfo::GetProxySubject().
| #define MAP_PROXYREQUEST ((DWORD)(1<<12)) |
When the proxy request flag is set, the BitmapInfo is called a request info.
A request info should contain settings for the original bitmap, without any subject info allocated. A request info passed to BitmapManager::Load() serves as a request to load proxy version of the original bitmap. The bitmap manager converts the request info to a proxy info with the complete proxy and subject settings. Indicates a request to load proxy bitmap, reduced from original size / bit depth
