Inherits From:

TModifiableImage

Inherited By:

None.

Purpose:

TC8M8Y8K8Image is a concrete 8-bit CMYK image. Each pixel of this image is specified with 32 bits. These 32 bits are divided into four 8-bit components: cyan, magenta, yellow, and the k-factor (which specifies the amount of black in the image). The results form a coordinate in a CMYK space. To derive an XYZcolor from this CMYK quadruplet, use the TColorProfile of the Image.

Instantiation:

Allocate on the heap or the stack.

Deriving Classes:

None.

Concurrency:

Not multithread safe.

Resource Use:

No special requirements.

Other Considerations:

None.

Interface Category:

API.

Purpose:

Default constructor.
Creates a TC8M8Y8K8Image from another type of image.
Copy constructor.
Creates a TC8M8Y8K8Image initialized with the given parameters.
Creates a TC8M8Y8K8Image initialized with the given parameters.

Calling Context:

Called by the stream-in operators.
Call to create a TC8M8Y8K8Image from another type of image.
Called to copy an object.
Call to create a new TC8M8Y8K8Image.
Call to create a new TC8M8Y8K8Image.

Parameters:

Takes no parameters.
const TImage & -The image from which to construct the TA8R8G8B8Image.
const TC8M8Y8K8Image & -The image to be copied.
const TGPoint & dstOrigin -The origin of the image in world space.
long widthInPixels -The width of the image measured in pixels.
long heightInPixels -The height of the image measured in pixels.
TGPoint dpi =TGImage :: k72DPI -The vertical and horizontal resolution of the image. The default value for both axes is 72 dpi.
TGrafBundle * adoptBundle =NIL -The initial attribute bundle for the image. The default value is NIL.
TGImage :: EOrientation orientation =TGImage :: kIdentity -The initial orientation for the image. The default value is kIdentity; the orientation of the image as stored in memory.
const TColorProfile & theProfile =* TColorProfile :: GetDefaultColorProfile () -The color profile for the image.
const TGPoint & sourceOrigin =TGPoint ( 0 , 0 ) -The offscreen origin for the image.
const TGPoint & dstOrigin -The origin of the image in world space.
const TGPoint & imageSizeInWorldSpace -The height and width of the image in world space.
TGPoint dpi =TGImage :: k72DPI -The vertical and horizontal resolution of the image. The default value for both axes is 72 dpi.
TGrafBundle * adoptBundle =NIL -The initial attribute bundle for the image. The default value is NIL.
TGImage :: EOrientation orientation =TGImage :: kIdentity -The initial orientation for the image. The default value is kIdentity; the orientation of the image as stored in memory.
const TColorProfile & theProfile =* TColorProfile :: GetDefaultColorProfile () -The color profile for the image.
const TGPoint & sourceOrigin =TGPoint ( 0 , 0 ) -The offscreen origin for the image.
