LOGCOLORSPACE
The LOGCOLORSPACE structure contains information that defines a logical color space.
typedef struct tagLOGCOLORSPACE {
DWORD lcsSignature;
DWORD lcsVersion;
DWORD lcsSize;
LCSCSTYPE lcsCSType;
LCSGAMUTMATCH lcsIntent;
CIEXYZTRIPLE lcsEndpoints;
DWORD lcsGammaRed;
DWORD lcsGammaGreen;
DWORD lcsGammaBlue;
TCHAR lcsFilename[MAX_PATH];
} LOGCOLORSPACE, *LPLOGCOLORSPACE;
Members
lcsSignature
Color space signature.
lcsVersion
Version number; must be 0x400.
lcsSize
Size of this structure, in bytes.
lcsCSType
Color space type. Can be one of the following values:
Value
| Meaning
| LCS_DEVICE_RGB
| Color values are device RGB values. The values are passed to the device
without translation.
| LCS_DEVICE_CMYK
| Color values are device CMYK values. The values are passed to the device
without translation
| LCS_CALIBRATED_RGB
| Color values are calibrated RGB values. The values are translated using the
endpoints specified by the lcsEndpoints member before being passed to the device.
|
If LCS_CALIBRATED_RGB is not specified, the lcsEndpoints member is ignored.
lcsIntent
The gamut matching method. Can be one of the following values:
LCS_GM_BUSINESS
| Maintain saturation. Used for business charts and other situations in which
undithered colors are required.
| LCS_GM_GRAPHICS
| Maintain colormetric match. Used for graphic designs and named colors.
| LCS_GM_IMAGES
| Maintain contrast. Used for photographs and natural images.
|
lcsEndpoints
Red, green, blue endpoints.
lcsGammaRed
Scale of the red coordinate.
lcsGammaGreen
Scale of the green coordinate.
lcsGammaBlue
Scale of the blue coordinate.
lcsFilename
A null-terminated string that names a color profile file. This member is
typically set to zero, but may be used to set the color space to be exactly as
specified by the color profile. This is useful for devices that input color values
for a specific printer, or when using an installable image color matcher. If a
color profile is specified, all other members of this structure should be set to
reasonable values, even if the values are not 100 percent accurate.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
