RotateCommand Constructor(int,RotateCommandFlags,RasterColor)

Summary

Initializes a new instance of the RotateCommand class with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public RotateCommand( 
   int angle, 
   RotateCommandFlags flags, 
   RasterColor fillColor 
)

- (instancetype)initWithAngle:(NSInteger)angle 
                        flags:(LTRotateCommandFlags)flags 
                    fillColor:(LTRasterColor *)fillColor

public RotateCommand( 
  int angle,  
  int flags,  
  RasterColor fillColor 
)

public: 
RotateCommand(  
   int angle, 
   RotateCommandFlags flags, 
   RasterColor fillColor 
)

__init__(self,angle,flags,fillColor) # Overloaded constructor

Parameters

angle
Hundredths of degrees to rotate (+/-). This can be a number from 1 to 36,000. A positive value will rotate the image in a clockwise rotation, while a negative value will rotate the image in a counter-clockwise rotation.

flags
Flag to keep the resulting image the same size as the original image or to resize according to the rotation direction specified.

fillColor
The background fill color.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
 
public void RotateCommandExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
	string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "RotateCommand.bmp"); 
 
	// Load the source image from disk 
	RasterImage image = codecs.Load(srcFileName); 
 
	// Rotate the image by 45 degrees 
	RotateCommand command = new RotateCommand(); 
	command.Angle = 45 * 100; 
	command.FillColor = new RasterColor(255, 255, 255); 
	command.Flags = RotateCommandFlags.Bicubic; 
	command.Run(image); 
 
	// Save it to disk 
	codecs.Save(image, destFileName, RasterImageFormat.Bmp, 24); 
 
	// Clean Up 
	image.Dispose(); 
	codecs.Dispose(); 
}
