常数

 

ImageFlagsNone

 

Specifies no format information.

 

ImageFlagsScalable

 

Specifies that the image can be scaled.

 

ImageFlagsHasAlpha

 

Specifies that the pixel data contains alpha values.

 

ImageFlagsHasTranslucent

 

Specifies that the pixel data has alpha values other than 0 (transparent) and 255 (opaque).

 

ImageFlagsPartiallyScalable

 

Specifies that the pixel data is partially scalable with some limitations.

 

ImageFlagsColorSpaceRGB

 

Specifies that the image is stored using an RGB color space.

 

ImageFlagsColorSpaceCMYK

ImageFlagsHasRealDPI

 

Specifies that dots per inch information is stored in the image.

 

ImageFlagsHasRealPixelSize

 

Specifies that the pixel size is stored in the image.

 

ImageFlagsReadOnly

 

Specifies that the pixel data is read-only.

 

ImageFlagsCaching

 

Specifies that the pixel data can be cached for faster access.
