Hi,
We purchased licence for ievision dll approx. one month ago, for
implementing our OCR exe.
Everything works fine except one thing. Dll ignores page orientation and OCR text is in that case, only mess of characters.
I tried solution on your support page, but problem is still there.
Rotation not worked.
// perform OCR
angle :=m_OCR.getTextAngle(ImageEnVect1.IEBitmap.GetIEVisionImage()) *
180 / PI;
ImageEnVect1.IEBitmap.Origin := ieboBOTTOMLEFT;
ImageEnVect1.Proc.Rotate(-angle);
SetOCRParams();
ocrrect := ImageEnVect1.SelectedRect;
memo1.Lines.Text :=
m_OCR.recognize(ImageEnVect1.IEBitmap.GetIEVisionImage(),
IEVisionRect(ocrrect.x, ocrrect.y, ocrrect.width, ocrrect.height)).c_str();
Is there any way to automatically recognise text orientation and rotate picture in right direction, before starting OCR?
Thanks in advance and have a nice day,
Milenko. |

FYI, the next version of IEVision will improve the detection of rotated documents.

Thanks Fabrizio,
Your solution works fine for 90 degrees rotated documents and that's acceptable for our application purpose. IEVision.dll is great product and has fine price/performance ratio.
I was away. Sorry for late answer. Regards, M. |

It is not simple to detect the right angle when the image is rotated by 90/180/etc degrees...
Anyway following works for your image:
ImageEnView1.IO.LoadFromFile(filename);
ImageEnView1.Proc.Rotate(ImageEnView1.Proc.CalcOrientation());

Thanks for your reply Fabrizio. Here is one image example, another one has Nigel in his mailbox... :-)
