| Icon | Member | Description |
|---|---|---|
 | GifComponent()()() |
Constructor.
This is implicitly called by constructors of derived types.
|
  | CodeApplicationExtensionLabel |
Application extension label - identifies the current block as a
ApplicationExtension.
Value 0xFF.
|
| CodeCommentLabel |
Comment label - identifies the current block as a comment extension.
Value 0xFE.
TODO: add see cref once CommentExtension class is implemented.
|
| CodeExtensionIntroducer |
Extension introducer - identifies the start of an extension block.
Value 0x21.
|
| CodeGraphicControlLabel |
Graphic control label - identifies the current block as a
GraphicControlExtension.
Value 0xF9.
|
| CodeImageSeparator |
Image separator - identifies the start of an
ImageDescriptor.
Value 0x2C.
|
| CodePlaintextLabel |
Plain text label - identifies the current block as a plain text
extension.
Value 0x01.
TODO: add see cref once PlainTextExtension class implemented
|
| CodeTrailer |
Trailer - This is a single-field block indicating the end of the GIF
data stream.
Value 0x3B.
|
 | ComponentStatus |
Gets the status of this component, consisting of its error state
and any associated error message.
|
| ConsolidatedState |
Gets the combined error states of this component and all its child
components.
|
 | Equals(Object) | (Inherited from Object.) |
| ErrorMessage |
Gets any error message associated with the component's error state.
|
| ErrorState |
Gets the member of the Gif.Components.ErrorState enumeration held
within the ComponentStatus property.
|
| Finalize()()() | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode()()() | 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.) |
| GetType()()() | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone()()() | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Read(Stream) |
Reads a single byte from the input stream and advances the position
within the stream by one byte, or returns -1 if at the end of the
stream.
|
| ReadShort(Stream) |
Reads next 16-bit value, least significant byte first, and advances
the position within the stream by two bytes.
|
| SetStatus(ErrorState, String) |
Sets the ComponentStatus property of thie GifComponent.
|
| SkipBlocks(Stream) |
Skips variable length blocks up to and including next zero length
block (block terminator).
|
| TestState(ErrorState) |
Tests whether the error state of this component or any of its member
components contains the supplied member of the ErrorState
enumeration.
|
| ToString()()() |
Gets a string representation of the error status of this component
and its subcomponents.
(Overrides Object.ToString()()().) |
| WriteByte(Int32, Stream) |
Writes the least significant byte of the supplied value to the
supplied stream.
The first 3 bytes of the supplied value are discarded.
|
| WriteShort(Int32, Stream) |
Writes a 16-bit value to the supplied output stream,
least-significant byte first.
The first two bytes in the supplied value are discarded.
|
| WriteString(String, Stream) |
Writes the supplied string to the supplied output stream
|
| WriteToStream(Stream) |
Appends the current GifComponent to the supplied output stream.
