Syntax
synchronized public void addLoadPageListener(CodecsLoadPageListener listener)
synchronized public void removeLoadPageListener(CodecsLoadPageListener listener)
public:
event EventHandler<CodecsPageEventArgs^>^ LoadPage
def LoadPage(sender,e): # sender: RasterCodecs e: CodecsPageEventArgs Event Data
The event handler receives an argument of type CodecsPageEventArgs containing data related to this event. The following CodecsPageEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| Command | A value indicating how the load or save process should continue. |
Example
using Leadtools;
using Leadtools.Codecs;
using Leadtools.ImageProcessing;
using Leadtools.ImageProcessing.Color;
using Leadtools.Svg;
private void Codecs_LoadSavePage(object sender, CodecsPageEventArgs e)
{
if (e.State == CodecsPageEventState.After)
Debug.WriteLine("The image has been processed");
else
Debug.WriteLine("The image has not processed yet");
if (e.Page > 5)
e.Command = CodecsPageEventCommand.Stop;
Debug.WriteLine("File name is: {0}", e.FileName);
if (e.Image != null)
Debug.WriteLine("The Image width and height is: {0},{1}", e.Image.Width, e.Image.Height);
Debug.WriteLine("Page Index is: {0}", e.Page);
Debug.WriteLine("Page Count is: {0}", e.PageCount);
