ImgDeskewSafe

Prototype

floatAngle:=ImgDeskewSafe(intImageHandle, intRange, floatResolution, intStep, boolIfWhiteBackground, boolIfInterpolation)

Description

Deskew the image as ImgDeskew but avoid to loose info on borders because it increases the size of image before rotating.

Parameters

intImageHandle: integer value corresponding to the image handle.

intRange: integer value that specifies the range of deskewing (between -SpecifiedValue and +SpecifiedValue);

floatResolution: resolution used in deskew procedure.

intStep: rows step in the loop that reads and analyzes rows of the image (0: Automatic; 1:All the rows)

boolIfWhiteBackground: boolean that specifies if background created by rotation is filled by white or black ink;

boolIfInterpolation: boolean that specifies if you want to use Interpolation.

Returned value

floatAngle : calculated deskew angle.

Notes

None.

Example

// Save original width and height

OWidth:=ImgGetWidth(_CurrentImage);

OHeight:=ImgGetHeight(_CurrentImage);

// Image safe deskewing

angle:=ImgDeskewSage(_CurrentImage, 5, 0.1, 0, False, False);

// Retrieve new width and height

NWidth:=ImgGetWidth(_CurrentImage);

NHeight:=ImgGetHeight(_CurrentImage);

// Log a message with deskewd angle

ApplicationLog('Safe deskewed image: '+ FloatToStr(angle) +'°.');

// Log a message with old size

ApplicationLog('Old image size: '+ IntToStr(OWidth)+'x'IntToStr(OHeight));

// Log a message with new size

ApplicationLog('New image size: '+ IntToStr(NWidth)+'x'IntToStr(NHeight));
