BytesPerLine Property

Summary
Gets the number of bytes per scanline for the image data of this RasterImage.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public int BytesPerLine { get; } 
@property (nonatomic, assign, readonly) NSUInteger bytesPerLine 
public int getBytesPerLine(); 
public: 
property int BytesPerLine { 
   int get(); 
} 
BytesPerLine # get  (RasterImage) 

Property Value

Number of bytes per per scanline for the image data of this RasterImage.

Remarks

The BytesPerLine value is rounded upward to the nearest multiple of four.

You can use this property to allocate the buffer size when manipulating the scanline data of a RasterImage directly through the GetRow and SetRow methods.

Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Core; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Dicom; 
using Leadtools.Drawing; 
using Leadtools.Controls; 
using Leadtools.Svg; 
 
 
public void GetRowTest() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
	RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
	byte[] row1 = new byte[image.BytesPerLine]; 
	byte[] row2 = new byte[image.BytesPerLine]; 
 
	image.Access(); 
	for (int y = 0; y < image.Height / 2; y++) 
	{ 
		image.GetRow(y, row1, 0, row1.Length); 
		image.GetRow(image.Height - y - 1, row2, 0, row2.Length); 
 
		image.SetRow(y, row2, 0, row2.Length); 
		image.SetRow(image.Height - y - 1, row1, 0, row1.Length); 
	} 
	image.Release(); 
 
	codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1_getrow.BMP"), RasterImageFormat.Bmp, 0); 
 
	image.Dispose(); 
	codecs.Dispose(); 
}
