ProgressEventHandlerInfo

Inheritance: java.lang.Object

public class ProgressEventHandlerInfo

This class represents information about image load/save/export operations progress, that can be used in external application to show conversion progress to end user

Methods

MethodDescription
getDescription()Gets the description of the event
getEventType()Gets the type of the event.
getMaxValue()Gets the upper progress value limit.
getValue()Gets current progress value.

Example: The following example shows how to print information about progress events for load/export operations.

String dir = "c:\\aspose.imaging\\java\\issues\\1440\\";
String fileName = dir + "big.png";

// Example of use of separate operation progress event handlers for load/export operations
final com.aspose.imaging.ProgressEventHandler loadHandler = new com.aspose.imaging.ProgressEventHandler() {
    @Override
    public void invoke(com.aspose.imaging.progressmanagement.ProgressEventHandlerInfo info) {
        System.out.format("Load event %s : %d/%d\n", com.aspose.imaging.progressmanagement.EventType.toString(com.aspose.imaging.progressmanagement.EventType.class, info.getEventType()), info.getValue(), info.getMaxValue());
    }
};

final com.aspose.imaging.ProgressEventHandler exportHandler = new com.aspose.imaging.ProgressEventHandler() {
    @Override
    public void invoke(com.aspose.imaging.progressmanagement.ProgressEventHandlerInfo info) {
        System.out.format("Export event %s : %d/%d\n", com.aspose.imaging.progressmanagement.EventType.toString(com.aspose.imaging.progressmanagement.EventType.class, info.getEventType()), info.getValue(), info.getMaxValue());
    }
};

com.aspose.imaging.Image image = com.aspose.imaging.Image.load(fileName, new com.aspose.imaging.LoadOptions() {{ setProgressEventHandler(loadHandler); }} );
try {
    image.save(fileName + ".psd",
            new com.aspose.imaging.imageoptions.PsdOptions() {{ setProgressEventHandler( exportHandler); }});
}
finally {
    image.close();
}

// The STDOUT log may look like this:
//        Load event Initialization : 1/4
//        Load event PreProcessing : 2/4
//        Load event Processing : 3/4
//        Load event Finalization : 4/4
//        Export event Initialization : 1/4
//        Export event PreProcessing : 2/4
//        Export event Processing : 3/4
//        Export event RelativeProgress : 1/1
//        Load event RelativeProgress : 1/1
//        Export event Finalization : 4/4
