Leadtools.Jpeg2000 Namespace > Jpeg2000Engine Class > LoadComposite Method : LoadComposite(RasterCodecs,Stream,Int32,CodecsLoadByteOrder) Method



codecs
The Leadtools.Codecs.RasterCodecs object.
stream
A System.IO.Stream containing the image data being loaded.
bitsPerPixel
Resulting image pixel depth. If this value is zero [0], the image will have the original file’s pixel depth (the image will not be converted).
order

Color order for 16-, 24-, 32-, 48-, and 64-bit images. If the resulting image is less than 16 bits per pixel, this will have no effect since palletized images do not use color order. Valid values are as follows:

Value Meaning
CodecsLoadByteOrder.Rgb Red, green, and blue color order in memory
CodecsLoadByteOrder.Bgr Blue, green, and red color order in memory
CodecsLoadByteOrder.Gray 12- or 16-bit grayscale image. 12- and 16-bit grayscale images are supported only in the Document/Medical Imaging editions.
CodecsLoadByteOrder.RgbOrGray Load the image as red, green, blue OR as a 12- or 16-bit grayscale image. 12- and 16-bit grayscale images are supported only in the Document/Medical Imaging editions.
CodecsLoadByteOrder.BgrOrGray Load the image as blue, green, red OR as a 12- or 16-bit grayscale image. 12- and 16-bit grayscale images are supported only in the Document/Medical Imaging editions.
CodecsLoadByteOrder.Romm ROMM order. ROMM only supports 24- and 48-bit images.
CodecsLoadByteOrder.BgrOrGrayOrRomm Load the image as red, green, blue OR as a 12- or 16-bit grayscale image OR as ROMM. 12- and 16-bit grayscale images are supported only in the Document/Medical Imaging editions. ROMM only supports 24- and 48-bit color images.
