Saving

ImGearFileFormats class provides the APIs needed to save a document/image. ImageGear only supports saving to a .NET Stream object that have the seek ability. If the save operation cannot be conducted, an exception with the following code is thrown: ImageGear.Core.ImGearErrorCodes.CANT_SAVE_FORMAT.

If the document size is close to 2GB, the System.OutOfMemoryException will be thrown.

Save a Single Page
Save a Document (Multiple Pages as a Document)

Save a Single Page

Use the SavePage method to a save a single page as follows:

C#	Copy Code
using System.IO; using ImageGear.Core; using ImageGear.Formats; public void SavePageToFile(ImGearPage loadedPage, string outputFilePath) { // Save to JPG file. using (FileStream fileStream = new FileStream(outputFilePath, FileMode.OpenOrCreate, FileAccess.ReadWrite)) { ImGearFileFormats.SavePage(loadedPage, fileStream, 0, ImGearSavingModes.OVERWRITE, ImGearSavingFormats.JPG); } }

Copy Code

using System.IO;
using ImageGear.Core;
using ImageGear.Formats;
public void SavePageToFile(ImGearPage loadedPage, string outputFilePath)
{
     // Save to JPG file.
     using (FileStream fileStream = new FileStream(outputFilePath, FileMode.OpenOrCreate, FileAccess.ReadWrite))
     {
          ImGearFileFormats.SavePage(loadedPage, fileStream, 0, ImGearSavingModes.OVERWRITE, ImGearSavingFormats.JPG);
     }
}

VB.NET	Copy Code
Imports System.IO Imports ImageGear.Core Imports ImageGear.Formats Public Sub SavePageToFile(loadedPage As ImGearPage, outputFilePath As String) ' Save to JPG file. Using fileStream As New FileStream(outputFilePath, FileMode.OpenOrCreate, FileAccess.ReadWrite) ImGearFileFormats.SavePage(loadedPage, fileStream, 0, ImGearSavingModes.OVERWRITE, ImGearSavingFormats.JPG) End Using End Sub

VB.NET

Copy Code

Imports System.IO
Imports ImageGear.Core
Imports ImageGear.Formats
Public Sub SavePageToFile(loadedPage As ImGearPage, outputFilePath As String)
            ' Save to JPG file.
            Using fileStream As New FileStream(outputFilePath, FileMode.OpenOrCreate, FileAccess.ReadWrite)
                        ImGearFileFormats.SavePage(loadedPage, fileStream, 0, ImGearSavingModes.OVERWRITE, ImGearSavingFormats.JPG)
            End Using
End Sub

Save a Document (Multiple Pages as a Document)

For this purpose, use the SaveDocument method. See What's the Best Format for...? for a list of the multi-page formats supported by ImageGear .NET, for example, PDF:

C#	Copy Code
using System.IO; using ImageGear.Core; using ImageGear.Formats; public void SaveDocumentToFile(ImGearDocument loadedPDFDocument, string outputFilePath) { // Save to PDF file. ImGearSaveOptions defaultSaveOptions = new ImGearSaveOptions(); using (FileStream fileStream = new FileStream(outputFilePath, FileMode.OpenOrCreate, FileAccess.ReadWrite)) { ImGearFileFormats.SaveDocument(loadedPDFDocument, fileStream, 0, ImGearSavingModes.OVERWRITE, ImGearSavingFormats.PDF, defaultSaveOptions); } }

Copy Code

using System.IO;
using ImageGear.Core;
using ImageGear.Formats;
public void SaveDocumentToFile(ImGearDocument loadedPDFDocument, string outputFilePath)
{
    // Save to PDF file.
    ImGearSaveOptions defaultSaveOptions = new ImGearSaveOptions();
    using (FileStream fileStream = new FileStream(outputFilePath, FileMode.OpenOrCreate, FileAccess.ReadWrite))
    {
        ImGearFileFormats.SaveDocument(loadedPDFDocument, fileStream, 0, ImGearSavingModes.OVERWRITE, ImGearSavingFormats.PDF, defaultSaveOptions);
    }
}

VB.NET	Copy Code
Imports System.IO Imports ImageGear.Core Imports ImageGear.Formats Public Sub SaveDocumentToFile(loadedPDFDocument As ImGearDocument, outputFilePath As String) ' Save to PDF file. Dim defaultSaveOptions As New ImGearSaveOptions() Using fileStream As New FileStream(outputFilePath, FileMode.OpenOrCreate, FileAccess.ReadWrite) ImGearFileFormats.SaveDocument(loadedPDFDocument, fileStream, 0, ImGearSavingModes.OVERWRITE, ImGearSavingFormats.PDF, defaultSaveOptions) End Using End Sub

VB.NET

Copy Code

Imports System.IO
Imports ImageGear.Core
Imports ImageGear.Formats
Public Sub SaveDocumentToFile(loadedPDFDocument As ImGearDocument, outputFilePath As String)
    ' Save to PDF file.
    Dim defaultSaveOptions As New ImGearSaveOptions()
    Using fileStream As New FileStream(outputFilePath, FileMode.OpenOrCreate, FileAccess.ReadWrite)
        ImGearFileFormats.SaveDocument(loadedPDFDocument, fileStream, 0, ImGearSavingModes.OVERWRITE, ImGearSavingFormats.PDF, defaultSaveOptions)
    End Using
End Sub
