Class StreamSource


  • public final class StreamSource
extends Source

    Represents a stream source.

    Code example:

    This example demonstrates how to use StreamSource to create a new Image file (a JPEG type)

    
//Creates an instance of JpegOptions and set its various properties
com.aspose.imaging.imageoptions.JpegOptions jpegOptions = new com.aspose.imaging.imageoptions.JpegOptions();

//Create an instance of System.IO.Stream
java.io.InputStream stream = new java.io.FileInputStream("C:\\temp\\sample.jpeg");

// Define the source property for the instance of JpegOptions
// Second boolean parameter determines if the Stream is disposed once get out of scope
jpegOptions.setSource(new com.aspose.imaging.sources.StreamSource(stream, true));

// Creates an instance of Image and call Create method with JpegOptions as parameter to initialize the Image object
com.aspose.imaging.Image image = com.aspose.imaging.Image.create(jpegOptions, 500, 500);
try {
    // Do some image processing
} finally {
    image.dispose();
}

    • Constructor Detail

      • StreamSource

        public StreamSource(com.aspose.ms.System.IO.Stream stream)

        Initializes a new instance of the StreamSource class.

        Parameters:
        stream - The stream to open.

      • StreamSource

        public StreamSource(InputStream stream)

        Initializes a new instance of the StreamSource class.

        Parameters:
        stream - The stream to open.

      • StreamSource

        public StreamSource()

        Initializes a new instance of the StreamSource class with Null stream. This constructor allows to create new images without input stream, images stored only in memory.

      • StreamSource

        public StreamSource(RandomAccessFile file)

        Initializes a new instance of the StreamSource class.

        Parameters:
        file - The file to open.

      • StreamSource

        public StreamSource(com.aspose.ms.System.IO.Stream stream,
                    boolean disposeStream)

      • StreamSource

        public StreamSource(InputStream stream,
                    boolean disposeStream)

        Initializes a new instance of the StreamSource class.

        Parameters:
        stream - The stream to open.
        disposeStream - if set to true the stream will be disposed.
        Code example:

        This example demonstrates how to use StreamSource to create a new Image file (a JPEG type)

        
//Creates an instance of JpegOptions and set its various properties

//Create an instance of System.IO.Stream
java.io.InputStream stream = new java.io.FileInputStream("C:\\temp\\sample.jpeg");

// Define the source property for the instance of JpegOptions
// Second boolean parameter determines if the Stream is disposed once get out of scope
jpegOptions.setSource(new com.aspose.imaging.sources.StreamSource(stream, true));

// Creates an instance of Image and call Create method with JpegOptions as parameter to initialize the Image object
com.aspose.imaging.Image image = com.aspose.imaging.Image.create(jpegOptions, 500, 500);
try {
    // Do some image processing
} finally {
    image.dispose();
