Outline of Converting Excel to Raster Images in C#
Converting Microsoft Excel document to raster GIF image with our Excel to Raster Images Library SDK for C#.NET is an easy job. GIF refers to the Graphics Interchange Format and is a good format for graphics on the web.

It is widely used on the web because of its extensive support and high portability.

Developers may use our .NET Excel to Raster Images Converter Control to convert Excel file to PNG image format in C#.NET application. PNG format is created as an improved substitute of GIF image format.

It uses lossless compression that is especially suitable to master copy data. Meanwhile, PNG file integrates special preprocessing filters to promote lossless compression efficiency.
Our .NET Excel to Raster Images Conversion Tool completely allows for rendering Excel document to JPEG image format within C# project. JPEG image format is able to display millions of colors at one time.

As it uses lossy compression, it is necessary to consider the balance of quality and file size when setting the compression value in practical use. JPEG image is often used for photo images that must be small in size, like photos in an E-mail or on web sites.
In addition to GIF, PNG and JPEG, BMP is also supported by .NET Excel Document Conversion SDK. In brief, BMP also known as device independent bitmap (DIB) file format, which is able to store 2D digital images of arbitrary width, height and resolution. It can be monochrome or color, in various color depths, and optionally with data compression, alpha channels, and color profiles.

APIs for Converting Excel to Raster Images in C#
The APIs used for Excel to raster images conversion are provided here. Also, the indispensible DLLs include RasterEdge.Imaging.Basic.dll, RasterEdge.Imaging.Basic.Codec.dll and RasterEdge.Imaging.MSExcel.dll.
// in XLSXDocument
void ConvertToImages(ImageType target, String directory, String fileName);
void ConvertToImages(ImageType targetType, float zoomValue, String directory, String fileName);
// in XLSXPage
void ConvertToImage(ImageType toType,String filePath);
void ConvertToImage(ImageType toType, float zoomValue, String filePath);
Note: Our C#.NET Excel Conversion Control SDK will not directly render Excel document to raster image formats. First of all, Excel document is rendered to our self-defined REImage object/collection (see
rendering Excel to get REImage collection in C#). And then, it is converted to other raster images.
Demo Code for Converting Excel to Raster Images in C#
The following C# demo code illustrates how to use our
C#.NET Excel Conversion Solution to render Excel document to other raster images (Here, we take PNG as an example). If you want to convert Excel to TIFF image file, please see
C# guide: convert Excel to TIFF.
// load an Excel document
XLSXDocument doc = new XLSXDocument (@"c:\sample.xlsx");
// convert all Excel document pages/sheets to PNG files
// page index will automatically append to the file name
doc.ConvertToImages(ImageType.PNG, @"c:\Test\", "sample");
// convert single page to PNG
XLSXPage page = (XLSXPage)doc.GetPage(0);
page.ConvertToImage(ImageType.PNG, @"c:\Test\sample1.png");
// convert to PNG with a zoom in factor of 2f
page.ConvertToImage(ImageType.PNG,2f, @"c:\Test\sample1.png");
