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.
| Parameter | Description |
| image | Source image |
| textOnly | If true then only text regions are returned. If False image regions (with no text) may also be returned |
Note:
◼ getRegions should be used with the
ievOCRAuto_OnlySegmenting or ievOCRAuto segmentation modes
◼ You can draw the rects to canvas using
DrawRectsExample
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;
