| Modifier and Type | Method and Description |
|---|---|
void |
addRegion(String regionName,
Rectangle2D rect)
Add a new region to group text by.
|
void |
extractRegions(PDPage page)
Process the page to extract the region text.
|
List<String> |
getRegions()
Get the list of regions that have been setup.
|
String |
getTextForRegion(String regionName)
Get the text for the region, this should be called after extractRegions().
|
protected void |
processTextPosition(TextPosition text)
This will process a TextPosition object and add the text to the list of characters on a page.
|
void |
setShouldSeparateByBeads(boolean aShouldSeparateByBeads)
This method does nothing in this derived class, because beads and regions are incompatible.
|
protected void |
showGlyph(Matrix textRenderingMatrix,
PDFont font,
int code,
String unicode,
Vector displacement)
This method was originally written by Ben Litchfield for PDFStreamEngine.
|
protected void |
writePage()
This will print the processed page text to the output stream.
