Add a new region to group text by.
|
void |
extractRegions(PDPage page)

|
void |
removeRegion(String regionName)
Delete a region to group text by.
|
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.
