A type of CGContext that you can use for drawing bits to memory.
Framework
The number of components for each pixel in a bitmap graphics context is specified by a color space, defined by a CGColor. The bitmap graphics context specifies whether the bitmap should contain an alpha channel, and how the bitmap is generated.
CGBitmapCreates a bitmap graphics context.
CGBitmapCreates a bitmap graphics context with the specified callback function.
CGBitmapCreates and returns a CGImage from the pixel data in a bitmap graphics context.
These functions return the values of attributes specified when a bitmap context is created.
CGBitmapObtains the bitmap information associated with a bitmap graphics context.
CGBitmapReturns the alpha information associated with the context, which indicates how a bitmap context handles the alpha component.
CGBitmapReturns the bits per component of a bitmap context.
CGBitmapReturns the bits per pixel of a bitmap context.
CGBitmapReturns the bytes per row of a bitmap context.
CGBitmapReturns the color space of a bitmap context.
CGBitmapReturns a pointer to the image data associated with a bitmap context.
CGBitmapReturns the height in pixels of a bitmap context.
CGBitmapReturns the width in pixels of a bitmap context.
CGBitmapA callback function used to release data associate with the bitmap context.
A set of components that define a color, with a color space specifying how to interpret them.
An object that describes how to convert between color spaces for use by other system services.
A profile that specifies how to interpret a color value for display.
A Quartz 2D drawing destination.
An abstraction for data-writing tasks that eliminates the need to manage a raw memory buffer.
An abstraction for data-reading tasks that eliminates the need to manage a raw memory buffer.
A set of character glyphs and layout information for drawing text.
A general facility for defining and using callback functions.
Deprecated. A type of CGContext for drawing OpenGL content.
A definition for a smooth transition between colors for drawing radial and axial gradient fills.
