◆ EventOccurred()
|
inlinevirtual |
Called when some event occurs during parsing a content stream.
- Parameters
-
data Combines the data required for processing corresponding event type. type Event type.
Implements iText.Kernel.Pdf.Canvas.Parser.Listener.IEventListener.
◆ GetResultantText()
|
inlinevirtual |
Returns the text that has been processed so far.
- Returns
-
System.String instance with the current resultant text
Implements iText.Kernel.Pdf.Canvas.Parser.Listener.ITextExtractionStrategy.
◆ GetSupportedEvents()
|
inlinevirtual |
Provides the set of event types this listener supports.
Provides the set of event types this listener supports. Returns null if all possible event types are supported.
- Returns
- Set of event types supported by this listener or null if all possible event types are supported.
Implements iText.Kernel.Pdf.Canvas.Parser.Listener.IEventListener.
◆ IsChunkAtWordBoundary()
|
inlinepackagevirtual |
Determines if a space character should be inserted between a previous chunk and the current chunk.
Determines if a space character should be inserted between a previous chunk and the current chunk. This method is exposed as a callback so subclasses can fine time the algorithm for determining whether a space should be inserted or not. By default, this method will insert a space if the there is a gap of more than half the font space character width between the end of the previous chunk and the beginning of the current chunk. It will also indicate that a space is needed if the starting point of the new chunk appears before the end of the previous chunk (i.e. overlapping text).
- Parameters
-
chunk the new chunk being evaluated previousChunk the chunk that appeared immediately before the current chunk
- Returns
- true if the two chunks represent different words (i.e. should have a space between them). False otherwise.
◆ IsUseActualText()
|
inlinevirtual |
Gets the value of the property which determines if /ActualText will be used when extracting the text
- Returns
- true if /ActualText value is used, false otherwise
◆ SetOutputChunkSeparator()
|
inlinevirtual |
Sets the string value used to separate chunks when formatting output.
- Parameters
-
outputChunkSeparator the string that will be used as a separator between chunks. Must not be null
- Returns
- this object
◆ SetOutputNewline()
|
inlinevirtual |
Sets the string value used to separate lines when formatting output.
- Parameters
-
outputNewline the string that will be used to represent a new line. Must not be null
- Returns
- this object
◆ SetRightToLeftRunDirection()
|
inlinevirtual |
Sets if text flows from left to right or from right to left.
Sets if text flows from left to right or from right to left. Call this method with true argument for extracting Arabic, Hebrew or other text with right-to-left writing direction.
- Parameters
-
rightToLeftRunDirection value specifying whether the direction should be right to left
- Returns
- this object
◆ SetUseActualText()
|
inlinevirtual |
Changes the behavior of text extraction so that if the parameter is set to true , /ActualText marked content property will be used instead of raw decoded bytes.
Changes the behavior of text extraction so that if the parameter is set to true , /ActualText marked content property will be used instead of raw decoded bytes. Beware: the logic is not stable yet.
- Parameters
-
useActualText true to use /ActualText, false otherwise
- Returns
- this object
