Crops specified region of an image.
Here is an example that shows how to load an image from disk, crop the specified region of the image and save the result to a new image file:
Class CropCommandExample
Public Sub ProcessImage()
' [ do not forget to set your image file path here! ]
' create an image collection
Using images As New Vintasoft.Imaging.ImageCollection()
' add image to the image collection
images.Add("Flower.jpg")
Try
Try
' for each image in image collection
For Each image As Vintasoft.Imaging.VintasoftImage In images
' create the image processing command
Dim command As New Vintasoft.Imaging.ImageProcessing.CropCommand(New System.Drawing.Rectangle(10, 10, image.Width - 10, image.Height - 10))
' subscribe to progress event of image processing command
AddHandler command.Progress, New System.EventHandler(Of Vintasoft.Imaging.ImageProcessing.ImageProcessingProgressEventArgs)(AddressOf command_Progress)
' apply the image processing command to the image
command.ExecuteInPlace(image)
Next
Catch ex As Vintasoft.Imaging.ImageProcessing.ImageProcessingException
' show error message
System.Windows.Forms.MessageBox.Show(ex.Message)
Return
End Try
' save the processed image collection to a new TIFF file
images.SaveSync("processed-image.tif")
Finally
images.ClearAndDisposeItems()
End Try
End Using
End Sub
Private Sub command_Progress(sender As Object, e As Vintasoft.Imaging.ImageProcessing.ImageProcessingProgressEventArgs)
' update progress info using e.Progress property
' ...
' cancel execution of command using e.Cancel property if necessary
' ...
End Sub
End Class
class CropCommandExample
{
public void ProcessImage()
{
// [ do not forget to set your image file path here! ]
// create an image collection
using (Vintasoft.Imaging.ImageCollection images = new Vintasoft.Imaging.ImageCollection())
{
// add image to the image collection
images.Add("Flower.jpg");
try
{
try
{
// for each image in image collection
foreach (Vintasoft.Imaging.VintasoftImage image in images)
{
// create the image processing command
Vintasoft.Imaging.ImageProcessing.CropCommand command =
new Vintasoft.Imaging.ImageProcessing.CropCommand(
new System.Drawing.Rectangle(10, 10, image.Width - 10, image.Height - 10));
// subscribe to progress event of image processing command
command.Progress +=
new System.EventHandler<Vintasoft.Imaging.ImageProcessing.ImageProcessingProgressEventArgs>(command_Progress);
// apply the image processing command to the image
command.ExecuteInPlace(image);
}
}
catch (Vintasoft.Imaging.ImageProcessing.ImageProcessingException ex)
{

}
}
}
