If the
source image is a YUV image, then this buffer should normally be

the height of the YUV image. However, the buffer may also be larger than
the dimensions of the JPEG image, in which case the <code>x</code>,
<code>y</code>, and <code>stride</code> parameters can be used to specify
the region into which the source image should be decompressed.</dd><dd><code>x</code> - x offset (in pixels) of the region in the destination image into
which the source image should be decompressed/decoded</dd><dd><code>y</code> - y offset (in pixels) of the region in the destination image into

specifies the desired width (in pixels) of the decompressed image (or
image region.) If the desired destination image dimensions are different
than the source image dimensions, then TurboJPEG will use scaling in the
JPEG decompressor to generate the largest possible image that will fit
within the desired dimensions. Setting this to 0 is the same as setting
it to the width of the JPEG image (in other words, the width will not be
considered when determining the scaled image size.) This parameter is
ignored if the source image is a YUV image.</dd><dd><code>stride</code> - pixels per line of the destination image. Normally, this
should be set to <code>scaledWidth</code>, but you can use this to, for
instance, decompress the JPEG image into a region of a larger image.
NOTE: if the source image is a JPEG image, then <code>scaledWidth</code>
can be determined by calling <code>
scalingFactor.<a href="../../../org/libjpegturbo/turbojpeg/TJScalingFactor.html#getScaled(int)"><code>getScaled</code></a>(jpegWidth)
</code> or by calling <a href="../../../org/libjpegturbo/turbojpeg/TJDecompressor.html#getScaledWidth(int,%20int)"><code>getScaledWidth(int, int)</code></a>. If the source image is a
YUV image, then <code>scaledWidth</code> is the width of the YUV image.
Setting this parameter to 0 is the equivalent of setting it to
<code>scaledWidth</code>.</dd><dd><code>desiredHeight</code> - If the source image is a JPEG image, then this
specifies the desired height (in pixels) of the decompressed image (or
image region.) If the desired destination image dimensions are different
