Accusoft Xpress Components

Converting DIB to HDIB

ImageGear for .NET provides a point of integration between the Xpress components and ImageGear, which allows you to copy the raster page DIB to the Xpress components HDIB. This can be done by using the ImGearRasterPage.CopyTo() method that makes a copy of the raster page's image data and gives the new image data to another object, which can be defined in a different Accusoft assembly. When finished, both the raster page and the destination object will contain separate copies of the same image data.

C# Example	Copy Code
using (FileStream fileStream = new FileStream("image.tif", FileMode.Open)) { // Load an image page. ImGearRasterPage page = ImGearFileFormats.LoadPage(fileStream, 0) as ImGearRasterPage; // Copy the page's DIB to the xpressComponent's HDIB. page.CopyTo(xpressComponent); }

C# Example

Copy Code

using (FileStream fileStream = new FileStream("image.tif", FileMode.Open))
{
    // Load an image page.
    ImGearRasterPage page = ImGearFileFormats.LoadPage(fileStream, 0) as ImGearRasterPage;
    // Copy the page's DIB to the xpressComponent's HDIB.
    page.CopyTo(xpressComponent);
}

Visual Basic Example	Copy Code
Using fileStream As New FileStream("image.tif", FileMode.Open, FileAccess.Read, FileShare.Read) ' Load an image page. Dim page As ImGearRasterPage = DirectCast(ImGearFileFormats.LoadPage(fileStream, 0), ImGearRasterPage) ' Copy the page's DIB to the xpressComponent's HDIB. page.CopyTo(xpressComponent) End Using

Visual Basic Example

Copy Code

Using fileStream As New FileStream("image.tif", FileMode.Open, FileAccess.Read, FileShare.Read)
    ' Load an image page.
    Dim page As ImGearRasterPage = DirectCast(ImGearFileFormats.LoadPage(fileStream, 0), ImGearRasterPage)
    ' Copy the page's DIB to the xpressComponent's HDIB.
    page.CopyTo(xpressComponent)
End Using

Using ImageGear from Xpress Components

ImageGear for .NET implements an internal interface that allows the ImGearRasterPage to act as a target of the CopyTo(), TransferTo() and Analyze() methods of the Xpress components, which makes it easier for the ImageGear for .NET and Xpress code to work together and for you to pass an HDIB to and from the Xpress components.

C# Example	Copy Code
using (FileStream fileStream = new FileStream("image.tif", FileMode.Open)) { // Load an image page. ImGearRasterPage page = ImGearFileFormats.LoadPage(fileStream, 0) as ImGearRasterPage; // Analyze loaded raster page using Xpress component. xpressComponent.Analyze(page); }

C# Example

Copy Code

using (FileStream fileStream = new FileStream("image.tif", FileMode.Open))
{
    // Load an image page.
    ImGearRasterPage page = ImGearFileFormats.LoadPage(fileStream, 0) as ImGearRasterPage;
    // Analyze loaded raster page using Xpress component.
    xpressComponent.Analyze(page);
}

Visual Basic Example	Copy Code
Using fileStream As New FileStream("image.tif", FileMode.Open, FileAccess.Read, FileShare.Read) ' Load an image page. Dim page As ImGearRasterPage = DirectCast(ImGearFileFormats.LoadPage(fileStream, 0), ImGearRasterPage) ' Analyze loaded raster page using Xpress component. xpressComponent.Analyze(page) End Using

Visual Basic Example

Copy Code

Using fileStream As New FileStream("image.tif", FileMode.Open, FileAccess.Read, FileShare.Read)
    ' Load an image page.
    Dim page As ImGearRasterPage = DirectCast(ImGearFileFormats.LoadPage(fileStream, 0), ImGearRasterPage)
    ' Analyze loaded raster page using Xpress component.
    xpressComponent.Analyze(page)
End Using
