The Imaging namespace provides advanced GDI+ imaging functionality. Basic graphics functionality is provided by the Drawing namespace.

## Classes

| Class | Description |
| --- | --- |
| [BitmapData](./bitmapdata/) | Specifies the attributes of a bitmap image. The BitmapData class is used by the LockBits and UnlockBits methods of the Bitmap class. Not inheritable. |
| [ColorMap](./colormap/) | Defines a map for converting colors. Several methods of the ImageAttributes class adjust image colors by using a color-remap table, which is an array of ColorMap structures. Not inheritable. |
| [ColorMatrix](./colormatrix/) | Defines a 5 x 5 matrix that contains the coordinates for the RGBA space. Several methods of the ImageAttributes class adjust image colors by using a color matrix. This class cannot be inherited. |
| [ColorPalette](./colorpalette/) | Defines an array of colors that make up a color palette. The colors are 32-bit ARGB colors. Not inheritable. |
| [Encoder](./encoder/) | An Encoder object encapsulates a globally unique identifier (GUID) that identifies the category of an image encoder parameter. |
| [EncoderParameter](./encoderparameter/) | Used to pass a value, or an array of values, to an image encoder. |
| [EncoderParameters](./encoderparameters/) | Encapsulates an array of EncoderParameter objects. |
| [FrameDimension](./framedimension/) | Provides properties that get the frame dimensions of an image. Not inheritable. |
| [ImageAttributes](./imageattributes/) | Contains information about how bitmap and metafile colors are manipulated during rendering. |
| [ImageCodecInfo](./imagecodecinfo/) | The ImageCodecInfo class provides the necessary storage members and methods to retrieve all pertinent information about the installed image encoders and decoders (called codecs). Not inheritable. |
| [ImageFormat](./imageformat/) | Specifies the file format of the image. Not inheritable. |
| [Metafile](./metafile/) | Defines a graphic metafile. A metafile contains records that describe a sequence of graphics operations that can be recorded (constructed) and played back (displayed). This class is not inheritable. |
| [MetafileHeader](./metafileheader/) | Contains attributes of an associated Metafile. Not inheritable. |
| [MetaHeader](./metaheader/) | Contains information about a windows-format (WMF) metafile. |
| [PlayRecordCallback](./playrecordcallback/) | This delegate is not used. For an example of enumerating the records of a metafile, see [`EnumerateMetafile`](../system.drawing/graphics/enumeratemetafile/). |
| [PropertyItem](./propertyitem/) | Encapsulates a metadata property to be included in an image file. Not inheritable. |
| [WmfPlaceableFileHeader](./wmfplaceablefileheader/) | Defines a placeable metafile. Not inheritable. |
## Enumeration

| Enumeration | Description |
| --- | --- |
| [ColorAdjustType](./coloradjusttype/) | Specifies which GDI+ objects use color adjustment information. |
| [ColorChannelFlag](./colorchannelflag/) | Specifies individual channels in the CMYK (cyan, magenta, yellow, black) color space. This enumeration is used by the [`SetOutputChannel`](../system.drawing.imaging/imageattributes/setoutputchannel/) methods. |
| [ColorMatrixFlag](./colormatrixflag/) | Specifies the types of images and colors that will be affected by the color and grayscale adjustment settings of an ImageAttributes. |
| [EmfPlusRecordType](./emfplusrecordtype/) | Specifies the methods available for use with a metafile to read and write graphic commands. |
| [EmfType](./emftype/) | Specifies the nature of the records that are placed in an Enhanced Metafile (EMF) file. This enumeration is used by several constructors in the Metafile class. |
| [EncoderValue](./encodervalue/) | Used to specify the parameter value passed to a JPEG or TIFF image encoder when using the EncoderParameters) or EncoderParameters) methods. |
| [ImageFlags](./imageflags/) | Specifies the attributes of the pixel data contained in an [`Image`](../system.drawing/image/) object. The Flags property returns a member of this enumeration. This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values. |
| [ImageLockMode](./imagelockmode/) | Specifies flags that are passed to the flags parameter of the [`LockBits`](../system.drawing/bitmap/lockbits/) method. The [`LockBits`](../system.drawing/bitmap/lockbits/) method locks a portion of an image so that you can read or write the pixel data. |
| [MetafileFrameUnit](./metafileframeunit/) | Specifies the unit of measurement for the rectangle used to size and position a metafile. This is specified during the creation of the Metafile object. |
| [MetafileType](./metafiletype/) | Specifies types of metafiles. |
| [PixelFormat](./pixelformat/) | Specifies the format of the color data for each pixel in the image. |
