CGImageMBS.kCGBitmapAlphaInfoMask = &h1F
Type | Topic | Plugin | Version |
const | CoreGraphics | MBS MacCG Plugin | 15.3 |
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 |
16-bit, big endian format.
CGImageMBS.kCGBitmapByteOrder16Little = 4096
Type | Topic | Plugin | Version |
const | CoreGraphics | MBS MacCG Plugin | 15.3 |
16-bit, little endian format.
CGImageMBS.kCGBitmapByteOrder32Big = 16384
Type | Topic | Plugin | Version |
const | CoreGraphics | MBS MacCG Plugin | 15.3 |
32-bit, big endian format.
CGImageMBS.kCGBitmapByteOrder32Little = 8192
Type | Topic | Plugin | Version |
const | CoreGraphics | MBS MacCG Plugin | 15.3 |
32-bit, little endian format.
CGImageMBS.kCGBitmapByteOrderDefault = 0
Type | Topic | Plugin | Version |
const | CoreGraphics | MBS MacCG Plugin | 15.3 |
The default byte order.
CGImageMBS.kCGBitmapByteOrderMask = &h7000
Type | Topic | Plugin | Version |
const | CoreGraphics | MBS MacCG Plugin | 15.3 |
The byte ordering of pixel formats.
CGImageMBS.kCGBitmapFloatComponents = 256
Type | Topic | Plugin | Version |
const | CoreGraphics | MBS MacCG Plugin | 15.3 |
The components of a bitmap are floating-point values.
CGImageMBS.kCGImageAlphaFirst = 4
Type | Topic | Plugin | Version |
const | CoreGraphics | MBS MacCG Plugin | 15.3 |
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 |
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 |
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 |
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 |
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 |
There is no color data, only an alpha channel.
CGImageMBS.kCGImageAlphaPremultipliedFirst = 2
Type | Topic | Plugin | Version |
const | CoreGraphics | MBS MacCG Plugin | 15.3 |
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 |
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.
