YResolution Property (CodecsRasterizeDocumentLoadOptions)






Gets or sets the vertical resolution to use for rasterization document files. .NET support WinRT support
Syntax
public int YResolution {get; set;}
'Declaration
 
Public Property YResolution As Integer
'Usage
 
Dim instance As CodecsRasterizeDocumentLoadOptions
Dim value As Integer
 
instance.YResolution = value
 
value = instance.YResolution
public int YResolution {get; set;}
 get_YResolution();
set_YResolution(value);
public:
property int YResolution {
   int get();
   void set (    int value);
}

Property Value

An System.Int32 value that indicates the vertical resolution to use for rasterization document files such as PDF and XPS. A value of 0 means to use the current screen resolution. The default value is 150.
Remarks

The resolution controls the pixel density of the resulting raster image. For example, if you specify 8.5 by 11 inches page width and height and a resolution of 96, the resulting image will have a pixel width and height of (8.5 * 96 = 816) and (11 * 96 = 1056) pixels. This is suitable for viewing at a 100 percent zoom but when you start zooming in, the image will get pixelated. Pixelation can also occur if you send the raster image to a printer, since printers usually have much higher resolution than a screen.

If zooming in or high quality printing is a requirement in your code, then a higher resolution value must be specified, for example 300 by 300. For an 8.5 by 11 inch document, this results in a raster image size if (8.5 * 300 = 2550) and (11 * 300 = 3300) pixels. More than suitable for printing or zooming in. Keep in mind that increasing the resolution increases the memory used to hold the image data. Finding the right balance between pixel density and memory consumption depends on the application's needs.

After the Leadtools.RasterImage is loaded, the image resolution set in RasterImage.XResolution and RasterImage.YResolution will be the same as XResolution and YResolution.

The horizontal resolution is specified in XResolution. For most normal usage, the value of XResolution and YResolution should be equal.

Example
For an example, refer to CodecsRasterizeDocumentLoadOptions.
