public class LegacyQTWriter
extends FormatWriter

LegacyQTWriter is a file format writer for QuickTime movies. It uses the QuickTime for Java library, and allows the user to choose between a variety of common video codecs. Much of this code was based on the QuickTime Movie Writer for ImageJ (available at http://rsb.info.nih.gov/ij/plugins/movie-writer.html).

               throws FormatException,
                      IOException

Description copied from interface: IFormatWriter

Saves the given image tile to the current series in the current file.

Parameters:

no - the image index within the current file, starting from 0.

buf - the byte array that represents the image tile.

x - the X coordinate of the upper-left corner of the image tile.

y - the Y coordinate of the upper-left corner of the image tile.

w - the width (in pixels) of the image tile.

h - the height (in pixels) of the image tile.

Throws:

FormatException - if one of the parameters is invalid.

IOException - if there was a problem writing to the file.

Description copied from interface: IFormatWriter

Saves the given image plane to the current series in the current file.

Specified by:

savePlane in interface IFormatWriter

Overrides:

savePlane in class FormatWriter

Parameters:

no - the image index within the current file, starting from 0.

plane - the image plane.

x - the X coordinate of the upper-left corner of the image tile.

y - the Y coordinate of the upper-left corner of the image tile.

w - the width (in pixels) of the image tile.

h - the height (in pixels) of the image tile.

Description copied from interface: IFormatWriter

Reports whether the writer can save multiple images to a single file.

Specified by:

canDoStacks in interface IFormatWriter

Overrides:

canDoStacks in class FormatWriter

getNativeDataType

public Class<?> getNativeDataType()

Description copied from interface: IFormatHandler

Returns the native data type of image planes for this reader, as returned by IFormatReader.openPlane(int, int, int, int, int) or IFormatWriter.savePlane(int, java.lang.Object). For most readers this type will be a byte array; however, some readers call external APIs that work with other types such as BufferedImage.
