Constructor Detail

PNGPixelRect

public PNGPixelRect(PixelFormat pixelformat,
                    DimensionImmutable size,
                    int strideInBytes,
                    boolean isGLOriented,
                    ByteBuffer pixels,
                    double dpiX,
                    double dpiY)

Creates a PNGPixelRect from data supplied by the end user. Shares data with the passed ByteBuffer.

Parameters:

pixelformat -

size -

strideInBytes -

isGLOriented - see PixelRectangle.GenericPixelRect.isGLOriented().

pixels -

dpiX -

dpiY -

PNGPixelRect

public PNGPixelRect(PixelRectangle src,
                    double dpiX,
                    double dpiY)

Method Detail

read

public static PNGPixelRect read(InputStream in,
                                PixelFormat ddestFmt,
                                boolean destDirectBuffer,
                                int destMinStrideInBytes,
                                boolean destIsGLOriented)
                         throws IOException

Reads a PNG image from the specified InputStream.

Implicitly converts the image to match the desired:

• PixelFormat, see PixelRectangle.GenericPixelRect.getPixelformat()
• destStrideInBytes, see PixelRectangle.GenericPixelRect.getStride()
• destIsGLOriented, see PixelRectangle.GenericPixelRect.isGLOriented()

Parameters:

in - input stream

destFmt - desired destination PixelFormat incl. conversion, maybe null to use source PixelFormat

destDirectBuffer - if true, using a direct NIO buffer, otherwise an array backed buffer

destMinStrideInBytes - used if greater than PNG's stride, otherwise using PNG's stride. Stride is width * bytes-per-pixel.

destIsGLOriented -

Returns:

the newly created PNGPixelRect instance

Throws:

IOException

getDpi

public double[] getDpi()

Returns the dpi of the image.
