Parameters

fileName

A String containing the output file name.

format

The output file format. For valid values, refer to Summary of All Supported Image File Formats.

bitsPerPixel

Resulting file's pixel depth. Note that not all bits per pixel are available to all file formats. For valid values, refer to Summary of All Supported Image File Formats. If bitsPerPixel is 0, the image will be stored using the closest bits per pixel value supported by that format. For example, if a file format supports 1, 4, and 24 bits per pixel, and RasterImage.BitsPerPixel is 5, the file will be stored as a 24-bit image. Likewise, if RasterImage.BitsPerPixel is 2, the file will be stored as 4-bit image.

qualityFactor

A quality factor to be used when saving the RasterImageViewerElement.Image to a file.

This example will load a 24 bits per pixel CMP image and save it as a 1 bit/pixel TIF image.

Copy Code

Public Sub RasterImageViewerElement_Save2(ByVal viewer As RasterImageViewerElement)    Dim srcFileName As String = "C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Image1.cmp"    Dim destFileName As String = "C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Image1_SaveFile1.tif"       ' Load the source file (make sure to load as 24 bits per pixel)    viewer.Load(srcFileName, 0, CodecsLoadByteOrder.Bgr, 1)    Console.WriteLine("Loaded image has {0} bpp", viewer.Image.BitsPerPixel)       ' Save it as a 1 BPP TIF    viewer.Save(destFileName, RasterImageFormat.Tif, 1, 128) End Sub

C#

Copy Code

public void RasterImageViewerElement_Save2(RasterImageViewerElement viewer)  {     string srcFileName = @"C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Image1.cmp";     string destFileName = @"C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Image1_SaveFile1.tif";       // Load the source file (make sure to load as 24 bits per pixel)     viewer.Load(srcFileName, 0, CodecsLoadByteOrder.Bgr, 1);     Console.WriteLine("Loaded image has {0} bpp", viewer.Image.BitsPerPixel);       // Save it as a 1 BPP TIF     viewer.Save(destFileName, RasterImageFormat.Tif, 1, 128);  }

You can set the qualityFactor parameter to a value from 2 to 255 when saving JPEG and LEAD CMP compressed images, where 2 represents the highest quality and 255 the most compression.

If the image is 8 bits per pixel or greater, use the LEAD CMP format or one of the JPEG (JTIF or JFIF) formats to save disk space.

If the image is 1 bit per pixel, use the LEAD 1-bit format or a CCITT Group 3 or 4 format to save disk space.
