getDefaultOptions(Object[] args)

public ImageOptionsBase getDefaultOptions(Object[] args)

Gets the default options.

Parameters:

ParameterTypeDescription

streamjava.io.OutputStreamThe stream to save the image’s data to.
optionsBaseImageOptionsBaseThe save options.

Example: This example shows the process of saving an Image to memory buffer. This example shows the process of saving an Image to memory buffer. To demonstrate this operation, example loads an existing file from some disk location and save the image in PSD format.

java.io.ByteArrayOutputStream stream = new java.io.ByteArrayOutputStream();
try {            //Create an instance of image class and initialize it with an existing image file through File path
    com.aspose.imaging.Image image = com.aspose.imaging.Image.load("C:\\temp\\sample.bmp");
    try {
        //Save the image to PSD memory stream with default PsdOptions settings
        image.save(stream, new com.aspose.imaging.imageoptions.PsdOptions());
    } finally {
        image.dispose();
    }
} finally {
    stream.close();
}

save(OutputStream stream, ImageOptionsBase optionsBase, Rectangle boundsRectangle)

public void save(OutputStream stream, ImageOptionsBase optionsBase, Rectangle boundsRectangle)

Saves the image’s data to the specified stream in the specified file format according to save options.

Parameters:

ParameterTypeDescription
streamjava.io.OutputStreamThe stream to save the image’s data to.
optionsBaseImageOptionsBaseThe save options.
boundsRectangleRectangleThe destination image bounds rectangle. Set the empty rectangle for use source bounds.

Example: The following example loads an image from a file, then saves a rectangular part of the image to a PNG file stream.

String dir = "c:\\temp\\";

com.aspose.imaging.Image image = com.aspose.imaging.Image.load(dir + "sample.bmp");
try {
    com.aspose.imaging.imageoptions.PngOptions saveOptions = new com.aspose.imaging.imageoptions.PngOptions();
    com.aspose.imaging.Rectangle bounds = new com.aspose.imaging.Rectangle(0, 0, image.getWidth(), image.getHeight() / 2);
    java.io.OutputStream outputStream = new java.io.FileOutputStream(dir + "sample.output.png");
    try {
        // Save the upper half of the image to a file stream.
        image.save(outputStream, saveOptions, bounds);
    } finally {
        outputStream.close();
    }
} finally {
    image.dispose();
}

setPalette(IColorPalette palette, boolean updateColors)

public abstract void setPalette(IColorPalette palette, boolean updateColors)

Sets the image palette.

Parameters:

ParameterTypeDescription
paletteIColorPaletteThe palette to set.
updateColorsbooleanif set to true colors will be updated according to the new palette; otherwise color indexes remain unchanged. Note that unchanged indexes may crash the image on loading if some indexes have no corresponding palette entries.
