APIs for Excel Conversion
In this section, we list the VB.NET APIs that you may use in the Excel converting process. As the whole VB.NET Excel conversion process can be divided into two main steps, which are rendering Excel page to image object and saving converted image object to desired image format, we present these VB.NET Excel converting APIs from following two aspects.

APIs to Render Excel to Image Object

Private Function GetPage(pageIndex As Integer) As BasePage Implements XLSXDocument.GetPage
End Function
Private Function toImage() As BaseImage Implements XLSXPage.toImage
End Function
Private Function toImage(height As Integer, width As Integer) As BaseImage Implements XLSXPage.toImage
End Function

API to Convert Image Object to Certain File Format

Private Sub SaveImageFile(image As REImage, filePath As [String]) Implements REFile.SaveImageFile
End Sub
API Explanation: XLSXDocument in above Excel converting APIs is a RasterEdge self-defined programming class, which is used to display one Excel file. XLSXPage is used as an abstraction of one Excel sheet. For displaying purpose, we regard one Excel sheet as a page.
