Method Detail

saveBytes

public void saveBytes(int no,
                      byte[] buf,
                      int x,
                      int y,

               throws FormatException,
                      java.io.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.

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

               throws FormatException,
                      java.io.IOException

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.

Throws:

FormatException - if one of the parameters is invalid.

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

IFormatWriter.savePlane(int, Object, int, int, int, int)

getPixelTypes

public int[] getPixelTypes(java.lang.String codec)

Description copied from interface: IFormatWriter

Gets the supported pixel types for the given codec.

Specified by:

getPixelTypes in interface IFormatWriter

Overrides:

getPixelTypes in class FormatWriter

getNativeDataType

public java.lang.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.

Specified by:

getNativeDataType in interface IFormatHandler

Overrides:

getNativeDataType in class FormatHandler
