    Initializing Assemblies
    In This Topic

    ImageGear assemblies require explicit initialization at application startup.

    Initialization Required Ordering

    The order in which these assemblies are initialized is important, because it defines format detection priority. The following order is recommended when initializing the assemblies needed in your application startup to ensure proper detection:

    Camera Raw formats should be initialized before Common formats, because many camera raw formats use custom versions of TIFF. If the application initializes Common formats before Camera Raw formats, ImageGear can incorrectly detect Camera Raw files as TIFF. Advanced formats will usually be initialized last, to allow for faster detection of Camera Raw and Common formats. Office formats and XPS format have similar signatures in the file's header. To ensure proper detection, Office formats should be initialized before XPS if you need to add support for both of them.

    Camera Raw Formats

    Assembly: ImageGear.Formats.CameraRaw.dll

    Supported Formats: CR2, CRW, DNG, Hasselblad RAW, Headerless , Imacon Raw, KodakRAW, LeicaRAW, MEF, MOS, MRW, NEF, ORF, PEF, PhaseOneRaw, RAF, SonyRaw

    C#
    Copy Code 
    using ImageGear.Core;
using ImageGear.Formats;
public void ApplicationStartupMethod()
{
     // License scope.

     // Initialize assemblies following the order recommended.
     ImGearCameraRawFormats.Initialize();
}
    VB.NET
    Copy Code 
    Imports ImageGear.Core
Imports ImageGear.Formats
Public Sub ApplicationStartupMethod()
            ' License scope.

            ' Initialize assemblies following the order recommended.
            ImGearCameraRawFormats.Initialize()
End Sub

    Headerless Camera Raw format doesn't have a file header, which makes its detection less reliable. Detection of this format in ImageGear is enabled by default. It is recommended that you move them to the end of the global formats list by adding the following piece of code below the initialization line:

    C#
    Copy Code 
    IImGearFormat headerlessRawFormat =ImGearFileFormats.Filters.Get(ImGearFormats.HeaderlessRaw);
ImGearFileFormats.Filters.Remove(ImGearFormats.HeaderlessRaw);
ImGearFileFormats.Filters.Add(headerlessRawFormat);
    VB.NET
    Copy Code 
    Dim headerlessRawFormat As IImGearFormat = ImGearFileFormats.Filters.[Get](ImGearFormats.HeaderlessRaw)
ImGearFileFormats.Filters.Remove(ImGearFormats.HeaderlessRaw)
ImGearFileFormats.Filters.Add(headerlessRawFormat)

    Common File Formats

    Assembly: ImageGear.Formats.Common.dll

    Supported Formats: BMP, CLP, CUR, DIB, GIF, ICO, JFIF, JPEG, PNG, RAW, TIFF

    C#
    Copy Code 
    using ImageGear.Core;
using ImageGear.Formats;
public void ApplicationStartupMethod()
{
     // License scope.

     // Initialize assemblies following the order recommended.
     ImGearCommonFormats.Initialize();
}
    VB.NET
    Copy Code 
    Imports ImageGear.Core
Imports ImageGear.Formats
Public Sub ApplicationStartupMethod()
            ' License scope.

            ' Initialize assemblies following the order recommended.
            ImGearCommonFormats.Initialize()
End Sub

    The Common File Formats component additionally provides two alternative file format implementations for JPEG and PNG. These file filters are based on native binary code which is unlike the default filters implemented on .NET. The difference between default and native implementation of JPEG and PNG is discussed in Native JPEG & PNG Filters.

    ImGearCommonFormats.Initialize() method initializes the file filter list with default JPEG and PNG filters. Update the filter list using ImGearFileFilters.Set(IImGearFormat format) method, which should be called after initialization to replace the default filters with native.

    C#
    Copy Code 
    using ImageGear.Core;
using ImageGear.Formats;
public void ApplicationStartupMethod()
{
     // License scope.
 
     // Initialize filter list with default set of common file formats.
     ImGearCommonFormats.Initialize();
   
    // Replace default (managed) JPEG and PNG file formats with native implementation.
    ImGearFileFormats.Filters.Set(ImGearCommonFormats.CreateJpegFormat());
    ImGearFileFormats.Filters.Set(ImGearCommonFormats.CreatePngFormat());
 
}
    VB.NET
    Copy Code 
    Imports ImageGear.Core
Imports ImageGear.Formats

Public Sub ApplicationStartupMethod()
    ' License scope.

    ' Initialize filter list with default set of common file formats.
    ImGearCommonFormats.Initialize()

    ‘ Replace default (managed) JPEG and PNG file formats with native implementation.
    ImGearFileFormats.Filters.Set(ImGearCommonFormats.CreateJpegFormat())
    ImGearFileFormats.Filters.Set(ImGearCommonFormats.CreatePngFormat())

End Sub

    Advanced File Formats

    Assembly: ImageGear.Formats.Advanced.dll 

    Supported Formats: BTR, CAL, CR2, CRW, CUT, DCX, GEM, IFF, IMG, IMR, IMT, IOCA, KFX, LV, MODCA, MSP, NCR, PBM, PCD, PCX, PGM, PNM, PPM, PSB, PSD, PTOCA, RAS, Scitex CT, SGI, TGA, WBMP, WPG, XBM, XPM, XWD

    C#
    Copy Code 
    using ImageGear.Core;
using ImageGear.Formats;
public void ApplicationStartupMethod()
{
     // License scope.

     // Initialize assemblies following the order recommended.
     ImGearAdvancedFormats.Initialize();
}
    VB.NET
    Copy Code 
    Imports ImageGear.Core
Imports ImageGear.Formats
Public Sub ApplicationStartupMethod()
            ' License scope.

            ' Initialize assemblies following the order recommended.
            ImGearAdvancedFormats.Initialize()
End Sub

    CUT format doesn't have a specific signature in the file's header, which makes its detection less reliable. Detection of this format in ImageGear is disabled by default. If you enable detection of this format, it is recommended that you move it to the end of the global formats list by adding the following piece of code below the initialization line:

    C#
    Copy Code 
    IImGearFormat cutFormat =ImGearFileFormats.Filters.Get(ImGearFormats.CUT);
ImGearFileFormats.Filters.Remove(ImGearFormats.CUT);
ImGearFileFormats.Filters.Add(cutFormat);
    VB.NET
    Copy Code 
    Dim cutFormat As IImGearFormat = ImGearFileFormats.Filters.[Get](ImGearFormats.CUT)
ImGearFileFormats.Filters.Remove(ImGearFormats.CUT)
ImGearFileFormats.Filters.Add(cutFormat)

    PDF and PS Formats

    Assembly: ImageGear.Formats.Pdf.dll

    This assembly requires both initialization and termination. Furthermore, the ImGearPDF.Initialize method does not add PDF and PostScript formats to the global format filter list. PDF and PostScript formats should be added explicitly before initialization, see PDF and PS in the "Additional Support" section, below.

    C#
    Copy Code 
    using ImageGear.Core;
using ImageGear.Formats;
using ImageGear.Formats.PDF;
public void ApplicationStartupMethod()
{
     // License scope.

     // Initialize assemblies following the order recommended.
     ImGearPDF.Initialize();
}

public void ApplicationEndPoint()
{
     // Terminate PDF Formats.
     ImGearPDF.Terminate();
}
    VB.NET
    Copy Code 
    Imports ImageGear.Core
Imports ImageGear.Formats
Public Sub ApplicationStartupMethod()
            ' License scope.

            ' Initialize assemblies following the order recommended.
            ImGearPDF.Initialize()
End Sub

Public Sub ApplicationEndPoint()
            ' Terminate PDF Formats.
            ImGearPDF.Terminate()
End Sub

    Simplified Metadata

    Assembly: ImageGear.Formats.SimplifiedMetadata.dll

    Supported Metadata Structures: EXIF Metadata Structure, IPTC Metadata Structure, TIFF Metadata Structure, XMP Metadata Structure

    C#
    Copy Code 
    using ImageGear.Core;
using ImageGear.Formats;
public void ApplicationStartupMethod()
{
     // License scope.

     // Initialize assemblies following the order recommended.
     ImGearSimplifiedMetadata.Initialize();
}
    VB.NET
    Copy Code 
    Imports ImageGear.Core
Imports ImageGear.Formats
Public Sub ApplicationStartupMethod()
            ' License scope.

            ' Initialize assemblies following the order recommended.
            ImGearSimplifiedMetadata.Initialize()
End Sub

    Additional Support

    The following ImageGear components also need to be explicitly added at application startup if required. The goal is to load the ImageGear capabilities for working with a specific set of formats that your application aims to process and that are not included in the assemblies initialized.

    Before adding any of these components, you need to have at least initialized Common Formats.

     // Require at least Common Formats.
     ImGearCommonFormats.Initialize();
     // Add support for PDF and PS
     ImGearFileFormats.Filters.Add(ImGearPDF.CreatePDFFormat());
     ImGearFileFormats.Filters.Add(ImGearPDF.CreatePSFormat());

     // Require PDF Formats.
     ImGearPDF.Initialize();

End Sub

    Office formats and XPS format have similar signatures in the file's header. To ensure proper detection, Office formats should be initialized before XPS if you need to add support for both of them. To use XPS, you need to add the assembly ImageGear.Wpf.dll.

    Global and Local Initialization

    After initializing ImageGear format filters, we can specify filter control parameters. Many format filters in ImageGear have control parameters that affect filter operations, such as image reading and writing. Those parameters may be declared by the format specification, or they may be specific to the format implementation by ImageGear. There are two ways to specify filter control parameters:

    Specify Parameters Globally

    This affects all format reading and writing operations, and threads in the process. Use the Filters static property of the ImGearFileFormats class to set parameters globally:

    C#
    Copy Code 
    IImGearFormat jpgFormat = ImGearFileFormats.Filters.Get(ImGearFormats.JPG);
ImGearControlParameter Param = jpgFormat.Parameters.GetByName("SaveType");
// Lossless.
Param.Value = 1;
    VB.NET
    Copy Code 
    Dim jpgFormat As IImGearFormat = ImGearFileFormats.Filters.[Get](ImGearFormats.JPG)
Dim Param As ImGearControlParameter = jpgFormat.Parameters.GetByName("SaveType")
' Lossless.
Param.Value = 1

    Specify Parameters Locally

    This affects only one reading or writing operation, and thus can be used for setting different parameters in different threads. To specify local parameters, create an instance of ImGearFileFilters class, assign it to ImGearLoadOptions.Filters property or ImGearSaveOptions.Filters property, and pass the Load or Save options object to the reading or writing method, correspondingly:

    C#
    Copy Code 
    ImGearFileFilters localFilters = new ImGearFileFilters();
IImGearFormat jpgFormat = localFilters.Get(ImGearFormats.JPG);
ImGearControlParameter controlParam = jpgFormat.Parameters.GetByName("SaveType");
// Lossless.
controlParam .Value = 1;
ImGearSaveOptions SaveOptions = new ImGearSaveOptions();
SaveOptions.Filters = localFilters;
    VB.NET
    Copy Code 
    Dim localFilters As New ImGearFileFilters()
Dim jpgFormat As IImGearFormat = localFilters.[Get](ImGearFormats.JPG)
Dim controlParam As ImGearControlParameter = jpgFormat.Parameters.GetByName("SaveType")
' Lossless.
controlParam.Value = 1
Dim SaveOptions As New ImGearSaveOptions()
SaveOptions.Filters = localFilters
