Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the bitmap info values.

The alpha information mask. Use this to extract alpha information that specifies whether a bitmap contains an alpha channel and how the alpha channel is generated.

CGImageMBS.kCGBitmapByteOrder16Big = 12288

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the bitmap info values.

16-bit, big endian format.

CGImageMBS.kCGBitmapByteOrder16Little = 4096

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the bitmap info values.

16-bit, little endian format.

CGImageMBS.kCGBitmapByteOrder32Big = 16384

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the bitmap info values.

32-bit, big endian format.

CGImageMBS.kCGBitmapByteOrder32Little = 8192

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the bitmap info values.

32-bit, little endian format.

CGImageMBS.kCGBitmapByteOrderDefault = 0

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the bitmap info values.

The default byte order.

CGImageMBS.kCGBitmapByteOrderMask = &h7000

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the bitmap info values.

The byte ordering of pixel formats.

CGImageMBS.kCGBitmapFloatComponents = 256

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the bitmap info values.

The components of a bitmap are floating-point values.

CGImageMBS.kCGImageAlphaFirst = 4

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the alpha info values.

The alpha component is stored in the most significant bits of each pixel. For example, non-premultiplied ARGB.

CGImageMBS.kCGImageAlphaLast = 3

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the alpha info values.

The alpha component is stored in the least significant bits of each pixel. For example, non-premultiplied RGBA.

CGImageMBS.kCGImageAlphaNone = 0

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the alpha info values.

There is no alpha channel. If the total size of the pixel is greater than the space required for the number of color components in the color space, the least significant bits are ignored. This value is equivalent to kCGImageAlphaNoneSkipLast.

CGImageMBS.kCGImageAlphaNoneSkipFirst = 6

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the alpha info values.

There is no alpha channel. If the total size of the pixel is greater than the space required for the number of color components in the color space, the most significant bits are ignored.

CGImageMBS.kCGImageAlphaNoneSkipLast = 5

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the alpha info values.

There is no alpha channel. If the total size of the pixel is greater than the space required for the number of color components in the color space, the least significant bits are ignored. This value is equivalent to kCGImageAlphaNone.

CGImageMBS.kCGImageAlphaOnly = 7

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the alpha info values.

There is no color data, only an alpha channel.

CGImageMBS.kCGImageAlphaPremultipliedFirst = 2

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the alpha info values.

The alpha component is stored in the most significant bits of each pixel and the color components have already been multiplied by this alpha value. For example, premultiplied ARGB.

CGImageMBS.kCGImageAlphaPremultipliedLast = 1

Type	Topic	Plugin	Version
const	CoreGraphics	MBS MacCG Plugin	15.3

One of the alpha info values.

The alpha component is stored in the least significant bits of each pixel and the color components have already been multiplied by this alpha value. For example, premultiplied RGBA.
