XResolution Property

Summary
Gets or sets the horizontal resolution used when creating new RasterImage objects.
Syntax
C#
Objective-C
C++/CLI
Python
public static int XResolution { get; set; } 
+(unsigned int)xResolution; 
+(void)xResolution:(unsigned int)value; 
public: 
static property int XResolution { 
   int get(); 
   void set (    int ); 
} 
XResolution # get and set (RasterDefaults) 

Property Value

An integer value that specifies the horizontal resolution used when creating new RasterImage objects. This value must be an integer value greater than zero.

Example
C#
using Leadtools; 
using Leadtools.Codecs; 
 
 
public void RasterDefaultsExample() 
{ 
	// Set the limit for RasterImage object allocations 
	RasterMemoryThreshold threshold = RasterDefaults.MemoryThreshold; 
	threshold.MaximumGlobalRasterImageMemory = 20 * 1000 * 1024; 
	RasterDefaults.MemoryThreshold = threshold; 
 
	ShowValues(); 
 
	// Create a raster image with current DPI 
	RasterImage image1 = new RasterImage( 
	   RasterMemoryFlags.Conventional, 
	   100, 
	   100, 
	   24, 
	   RasterByteOrder.Bgr, 
	   RasterViewPerspective.TopLeft, 
	   null, 
	   IntPtr.Zero, 
	   0); 
	Console.WriteLine("Resolution of created image is {0} by {1} DPI", image1.XResolution, image1.YResolution); 
 
	// Change the resolution 
	int xOldResolution = RasterDefaults.XResolution; 
	int yOldResolution = RasterDefaults.YResolution; 
	int xNewResolution = 196; 
	int yNewResolution = 196; 
	RasterDefaults.XResolution = xNewResolution; 
	RasterDefaults.YResolution = yNewResolution; 
	ShowValues(); 
 
	// Create another raster image 
	// Create a raster image with current DPI 
	RasterImage image2 = new RasterImage( 
	   RasterMemoryFlags.Conventional, 
	   100, 
	   100, 
	   24,

	Debug.Assert(image2.XResolution == xNewResolution); 
	Debug.Assert(image2.YResolution == yNewResolution); 
 
	// Reset old values 
	RasterDefaults.XResolution = xOldResolution; 
	RasterDefaults.YResolution = yOldResolution; 
 
	image1.Dispose(); 
	image2.Dispose(); 
}

	Console.WriteLine("DitheringMethod: {0}", RasterDefaults.DitheringMethod); 
	Console.WriteLine("MemoryFlags: {0}", RasterDefaults.MemoryFlags); 
 
	RasterMemoryThreshold threshold = RasterDefaults.MemoryThreshold; 
	Console.WriteLine("MemoryThreshold.TiledThreshold: {0}", threshold.TiledThreshold); 
	Console.WriteLine("MemoryThreshold.MaximumConventionalSize: {0}", threshold.MaximumConventionalSize); 
	Console.WriteLine("MemoryThreshold.TileSize: {0}", threshold.TileSize); 
	Console.WriteLine("MemoryThreshold.ConventionalTiles: {0}", threshold.ConventionalTiles); 
	Console.WriteLine("MemoryThreshold.ConventionalBuffers: {0}", threshold.ConventionalBuffers);
