DeskewCommand Constructor(RasterColor,DeskewCommandFlags)

Summary

Initializes a new DeskewCommand class object with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public DeskewCommand( 
   RasterColor fillColor, 
   DeskewCommandFlags flags 
)

- (instancetype)initWithFillColor:(LTRasterColor *)fillColor flags:(LTDeskewCommandFlags)flags NS_DESIGNATED_INITIALIZER;

public DeskewCommand( 
   RasterColor fillColor, 
   int flags 
)

public: 
DeskewCommand(  
   RasterColor fillColor, 
   DeskewCommandFlags flags 
)

__init__(self,fillColor,flags) # Overloaded constructor

Parameters

fillColor
Used to fill the background following rotation. This is used only if DeskewCommandFlags.FillExposedArea is set in the flags parameter.

flags
Flags that indicate whether to deskew the image, which background color to use, whether to deskew the image if the skew angle is very small, which type of interpolation to use, whether the image contains mostly text, and whether to use normal or fast rotation.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void DeskewCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   DeskewCommand command = new DeskewCommand(); 
   //Deskew the image. 
   command.Flags = DeskewCommandFlags.DeskewImage | DeskewCommandFlags.DoNotFillExposedArea; 
   command.Run(image); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
