SyntaxThe PdfLZWDecodeFilter type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PdfLZWDecodeFilter | Initializes a new instance of the PdfLZWDecodeFilter class |
Properties| Name | Description | |
|---|---|---|
 | BitsPerComponent | (May be used only if Predictor is greater than 1) The number of bits used to represent each color component in a sample. Valid values are 1, 2, 4, 8, and (PDF 1.5) 16. Default value: 8. |
| Colors | (May be used only if Predictor is greater than 1) The number of interleaved color components per sample. Valid values are 1 to 4 (PDF 1.0) and 1 or greater (PDF 1.3). Default value: 1. |
| Columns | (May be used only if Predictor is greater than 1) The number of samples in each row. Default value: 1. |
| EarlyChange | An indication of when to increase the code length. If the value is , code length increases shall be postponed as long as possible. If the value is , code length increases shall occur one code early. This parameter is included because LZW sample code distributed by some vendors increases the code length one code earlier than necessary. Default value: . |
| FilterType |
Gets the LZWDecode value.
(Overrides PdfFilterFilterType) |
| Predictor | A code that selects the predictor algorithm, if any. If the value is 1, the PdfFlateDecodeFilter shall assume that the normal algorithm was used to encode the data, without prediction. If the value is greater than 1, the PdfFlateDecodeFilter shall assume that the data was differenced before being encoded, and Predictor selects the predictor algorithm. For more information regarding Predictor values greater than 1, see 7.4.4.4, "LZW and Flate Predictor Functions". Default value: 1. |
| PredictorFunction | Gets or sets the predictor algorithm. Default value: None. |
