Field Detail

Rsiz

public int Rsiz

Denotes capabilities that a decoder needs to properly decode the codestream

NOTE: It would be better defined if it is considered like a enumeration. Therefore, the attribute name could be 'capabilities' as is defined in the standard, and it would contain only the required capabilities. It would avoid to used masks to extract capabilities.

xSize

public int xSize

Image width.

Negative values are not allowed for this field.

ySize

public int ySize

Image height.

Negative values are not allowed for this field.

XOsize

public int XOsize

Horizontal offset.

Horitzontal offset from origin of the reference grid to the left side of the image area

YOsize

public int YOsize

Vertical offset.

Vertical offset from origin of the reference grid to the left side of the image area

XTsize

public int XTsize

Horizontal tile size.

Width of one reference tile with respect ot the reference grid.

YTsize

public int YTsize

Vertical tile size.

Height of one reference tile with respect ot the reference grid.

XTOsize

public int XTOsize

Horizontal offset Tile

Horitzontal offset from the origin of the reference grid to the left side of the first tile

YTOsize

public int YTOsize

Vertical offset Tile

Vertical offset from the origin of the reference grid to the top side of the first tile

zSize

public int zSize

Number of image components.

Negative values are not allowed for this field.

precision

public int[] precision

Number of bits per sample used for each component.

Only positive values allowed.

signed

public boolean[] signed

Indicates whether components are signed (positive and negative values) or not.

True if signed, false otherwise.

XRsiz

public int[] XRsiz

Horitzontal separation of sample of ith component with respect to the reference grid. There is one occurence of this parameter for each compoenent.

Only positive values shorter than 255 are allowed.

YRsiz

public int[] YRsiz

Vertical separation of sample of ith component with respect to the reference grid. There is one occurence of this parameter for each compoenent.

Only positive values shorter than 255 are allowed.
