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: ImageGear23.Formats.CameraRaw.dll

Supported Formats: Hasselblad RAW, Headerless Camera Raw, 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 disabled by default. If you enable detection of these formats, 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: ImageGear23.Formats.Common.dll

Supported Formats: BMP, CLP, CUR, DCRAW, DIB, DNG, 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

Advanced File Formats

Assembly: ImageGear23.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: ImageGear23.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, 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: ImageGear23.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.

            ImGearFileFormats.Filters.Add(ImGearXPS.CreateXPSFormat())

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 ImageGear23.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
