TIEVisionOCR.getRegions

Declaration

function getRegions(textOnly: bool32 = false): TIEVisionVectorRect; overload; safecall;
function getRegions(image: TIEVisionImage; textOnly: bool32 = false): TIEVisionVectorRect; overload; safecall;

Description

Detect text regions (layout).
First overload takes last processed image as input.
Second overload takes the specified image as input.


Notes:
- getRegions should be used with the ievOCRAuto_Only or ievOCRAuto segmentation modes
- You can draw the rects to canvas using DrawRects

Example

OCR.setSegmentationMode(ievOCRAuto);
regions := OCR.getRegions(image);
for i := 0 to regions.size()-1 do
  with regions.getRect(i) do
  begin
    str := m_OCR.recognize(image, IEVisionRect(x, y, width, height));
  end;
