Property Value
An System.Int32 value that indicates the horizontal resolution to use when rasterization occurs on document files such as PDF and XPS. The default value is 0, which means it uses the current screen resolution.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 may 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 inches 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 will increase the memory used to hold the image data. Finding the right balance between pixel density and memory consumption depends on your application 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 vertical resolution is specified in YResolution. For most normal usage, the value of XResolution and YResolution should be equal.
If the value of CodecsRasterizeDocumentLoadOptions.Enabled is set to true, then XResolution and YResolution will be used instead of the following properties:
- When loading PDF documents: CodecsPdfLoadOptions.XResolution and CodecsPdfLoadOptions.YResolution
- When loading XPS documents: CodecsXpsLoadOptions.Resolution
- When loading RTF documents: CodecsRtfLoadOptions.XResolution and CodecsRtfLoadOptions.YResolution
