The Graphic Control Extension contains parameters used when processing a graphic rendering block. The scope of this extension is the first graphic rendering block to follow. The extension contains only one data sub-block. This block is OPTIONAL; at most one Graphic Control Extension may precede a graphic rendering block. This is the only limit to the number of Graphic Control Extensions that may be contained in a Data Stream.

|GraphicControlExtension(Int32, DisposalMethod, Boolean, Boolean, Int32, Int32)|
Number of bytes in the block, after the Block Size field and up to but not including the Block Terminator. This field contains the fixed value 4.
Gets the status of this component, consisting of its error state and any associated error message.(Inherited from GifComponent.)
Gets the combined error states of this component and all its child components.(Inherited from GifComponent.)
If not 0, this field specifies the number of hundredths (1/100) of a second to wait before continuing with the processing of the Data Stream. The clock starts ticking immediately after the graphic is rendered. This field may be used in conjunction with the User Input Flag field.
Indicates the way in which the graphic is to be treated after being displayed.
Gets any error message associated with the component's error state.(Inherited from GifComponent.)
Gets the member of the Gif.Components.ErrorState enumeration held within the ComponentStatus property.(Inherited from GifComponent.)
The expected block size for a Graphic Control Extension
Indicates whether or not user input is expected before continuing. If the flag is set, processing will continue when user input is entered. The nature of the User input is determined by the application (Carriage Return, Mouse Button Click, etc.). Values : 0 - User input is not expected. 1 - User input is expected. When a Delay Time is used and the User Input Flag is set, processing will continue when user input is received or when the delay time expires, whichever occurs first.
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.(Inherited from Object.)
Reads and returns a graphic control extension from the supplied input stream.
Serves as a hash function for a particular type. GetHashCode()()() is suitable for use in hashing algorithms and data structures like a hash table.(Inherited from Object.)
Gets the Type of the current instance.(Inherited from Object.)
Indicates whether a transparency index is given in the Transparent Index field.
Creates a shallow copy of the current Object.(Inherited from Object.)
Sets the ComponentStatus property of thie GifComponent.(Inherited from GifComponent.)
Tests whether the error state of this component or any of its member components contains the supplied member of the ErrorState enumeration.(Inherited from GifComponent.)
Gets a string representation of the error status of this component and its subcomponents.(Inherited from GifComponent.)
The Transparency Index is such that when encountered, the corresponding pixel of the display device is not modified and processing goes on to the next pixel. The index is present if and only if the Transparency Flag is set to 1.
Writes this component to the supplied output stream.(Overrides GifComponent.WriteToStream(Stream).)
