有没有人有一个工作代码示例显示调用 Windows 颜色系统函数WcsGetDefaultColorProfile以获取特定设备的默认颜色配置文件?当我为 pDeviceName 参数传递 null 时,它对我有用,但是当我尝试传递监视器的设备名称时,我总是返回错误代码 ERROR_FILE_NOT_FOUND。
我更喜欢 C# 示例,但我会尽我所能。我在任何地方都找不到较新的 WCS 配置文件管理功能的任何示例代码。

我遇到了同样的问题,您感到沮丧的原因是 MSDN 文档对 WcsGetDefaultColorProfile 的 pDeviceName 参数不正确(或充其量是误导)。
MSDN 文档 ( http://msdn.microsoft.com/en-us/library/dd372247(v=vs.85).aspx ) 表明 pDeviceName 指的是“设备名称”,对于显示设备,人们会假设为 Windows 显示设备名称,例如“\.\DISPLAY1”,在 EnumDisplayDevices 的 DISPLAY_DEVICE 结构的 DeviceName 参数中返回。
其实这里需要的是显示器的DeviceKey参数,具体来说就是在EnumDisplayDevices中使用EDD_GET_DEVICE_INTERFACE_NAME标志时得到的DeviceKey。
所以工作代码看起来像这样,假设 szDisplayDeviceName 已经设置为显示您关心的设备名称,例如“\.\DISPLAY1”:
WCHAR szPath[MAX_PATH];
DISPLAY_DEVICE dd;
dd.cb = sizeof(dd);
if (EnumDisplayDevices(szDisplayDeviceName, 0, &dd, EDD_GET_DEVICE_INTERFACE_NAME))
{
if (WcsGetDefaultColorProfile(WCS_PROFILE_MANAGEMENT_SCOPE_CURRENT_USER,
dd.DeviceKey,
CPT_ICC,
CPST_PERCEPTUAL,
1, // dwProfileID -- doesn't seem to matter what value you use here
MAX_PATH * sizeof(WCHAR),
szPath))
{
PROFILE profile;
profile.cbDataSize = (DWORD)(wcslen(szPath) + 1) * sizeof(WCHAR);
profile.dwType = PROFILE_FILENAME;
profile.pProfileData = (PVOID)szPath;
HPROFILE hProfile = OpenColorProfile(&profile,
PROFILE_READ, FILE_SHARE_READ, OPEN_EXISTING);
// now do something with the profile
}
}
跟进上面 Matt M 的回答(谢谢!):如果您想匹配其他应用程序的功能,请使用 EnumDisplayDevices 返回的第一个监视器,如上所述。
但请注意,这可能会在一个或多个监视器被禁用但仍连接的多监视器设置中返回不正确的(非活动/禁用)监视器。当然,微软没有在任何地方记录这一点,因此包括 Photoshop 等大玩家在内的许多应用程序在这方面都被破坏了:(
如果您想做正确的事情,您必须多次调用 EnumDisplayDevices 直到找到活动监视器(标志 DISPLAY_DEVICE_ACTIVE 和 DISPLAY_DEVICE_MULTI_DRIVER,以防多个监视器与显示器相关联)。
文档一点也不明显,但是从以前的答案中我拼凑了一个完整的解决方案(为了清楚起见,这里没有错误检查)。此外,这只会返回用户指定的默认值,如果他们从未设置过默认值,您将需要使用GetStandardColorSpaceProfile
来获取“其他”默认值。
DISPLAY_DEVICE displayDevice = {};
displayDevice.cb = sizeof(DISPLAY_DEVICE);
// First, find the primary adaptor
std::stringw adaptorName;
DWORD deviceIndex = 0;
while (::EnumDisplayDevicesW(nullptr, deviceIndex++, &displayDevice, EDD_GET_DEVICE_INTERFACE_NAME))
{
if (displayDevice.StateFlags & DISPLAY_DEVICE_ATTACHED_TO_DESKTOP &&
displayDevice.StateFlags & DISPLAY_DEVICE_PRIMARY_DEVICE)
{
adaptorName = displayDevice.DeviceName;
break;
}
}
// Second, find the first active (and attached) monitor
std::string deviceName;
deviceIndex = 0;
while (::EnumDisplayDevicesW(adaptorName, deviceIndex++, &displayDevice, EDD_GET_DEVICE_INTERFACE_NAME))
{
if (displayDevice.StateFlags & DISPLAY_DEVICE_ACTIVE &&
displayDevice.StateFlags & DISPLAY_DEVICE_ATTACHED)
{
deviceName = displayDevice.DeviceKey;
break;
}
}
// Third, find out whether to use the global or user profile
BOOL usePerUserProfiles = FALSE;
WcsGetUsePerUserProfiles(deviceName, CLASS_MONITOR, &usePerUserProfiles);
// Finally, get the profile name
const WCS_PROFILE_MANAGEMENT_SCOPE scope = usePerUserProfiles ? WCS_PROFILE_MANAGEMENT_SCOPE_CURRENT_USER : WCS_PROFILE_MANAGEMENT_SCOPE_SYSTEM_WIDE;
DWORD profileNameLength = 0; // In bytes
WcsGetDefaultColorProfileSize(scope, deviceName, CPT_ICC, CPST_RGB_WORKING_SPACE, 0, &profileNameLength);
wchar_t *const profileName = new wchar_t[profileNameLength / sizeof(wchar_t)];
WcsGetDefaultColorProfile(scope, deviceName, CPT_ICC, CPST_RGB_WORKING_SPACE, 0, profileNameLength, profileName);
// Do something with your profile name
delete[] profileName;
