常数

 

Ok

 

Indicates that the function call was successful.

 

GenericError

 

Indicates that there was an error on the function call, which is identified as something other than those defined by the other elements of this enumeration.

 

InvalidParameter

 

Indicates that one of the arguments passed to the function was not valid.

 

OutOfMemory

 

Indicates that the operating system is out of memory and could not allocate memory to process the function call.

 

ObjectBusy

 

Indicates that one of the arguments specified in the application programming interface (API) call is already in use in another thread.

 

InsufficientBuffer

 

Indicates that a buffer specified as an argument in the API call is not large enough to hold the data to be received.

 

NotImplemented

 

Indicates that the function is not implemented.

 

Win32Error

 

Indicates that the function generated a Microsoft Win32 error.

 

WrongState

 

Indicates that the object is in an invalid state to satisfy the API call.

 

Aborted

 

Indicates that the function was aborted.

 

FileNotFound

 

Indicates that the specified image file or metafile cannot be found.

 

ValueOverflow

 

Indicates that the function performed an arithmetic operation that produced a numeric overflow.

 

AccessDenied

 

Indicates that a write operation is not allowed on the specified file.

 

UnknownImageFormat

 

Indicates that the specified image file format is not known.

 

FontFamilyNotFound

 

Indicates that the specified font family cannot be found. Either the font family name is incorrect or the font family is not installed.

 

FontStyleNotFound

 

Indicates that the specified style is not available for the specified font family.

 

NotTrueTypeFont

 

Indicates that the font retrieved from an HDC or LOGFONT is not a TrueType font and cannot be used with GDI+.

 

UnsupportedGdiplusVersion

 

Indicates that the version of GDI+ that is installed on the system is incompatible with the version with which the application was compiled.

 

GdiplusNotInitialized

 

Indicates that the GDI+API is not in an initialized state. To function, all GDI+ objects require that GDI+ be in an initialized state. Initialize GDI+ by calling GdiplusStartup.

 

PropertyNotFound

 

Indicates that the specified property does not exist in the image.

 

PropertyNotSupported

 

Indicates that the specified property is not supported by the format of the image and, therefore, cannot be set.

 

ProfileNotFound

 

Indicates that the color profile required to save an image in CMYK format was not found.
