ImgAutoOrient

Prototype

intAngle:=ImgAutoOrient(intImageHandle)

Description

Orients the image correctly, rotating it by 90, 180 or 270° if required.

Parameters

intImageHandle: integer value corresponding to the image handle.

Returned value

intAngle : orientation angle before correction.

Notes

The orientation is computed making a statistical analysis of dark elements on the white background so cannot be 100% accurate. If you need more accuracy you could use our add-on allowing to orient the image by OCR. With this add-on you can be sure that the image is correctly oriented for natural reading.

Example

// Image auto orientation

Angle:=ImgAutoOrient(_CurrentImage);

// Log a message 

ApplicationLog('Orientation corrected: '+ IntToStr(Angle) +'°.');
