public static void decodeJPEG(byte[] jpegData, int jpegDataOffset, int jpegDataLength, int[] bounds, int boundsOffset, Buffer rgb565)
Decodes a JPEG encoded image into an OpenGL ES compatible
GL10.GL_UNSIGNED_SHORT_5_6_5 buffer. May also be used
to determin the bounds of an image prior to decoding it.
Parameters
| jpegData | the source JPEG data |
|---|---|
| bounds | the buffer where the bounds will be reported. May be null, in which case no bounds are returned. The bounds will be returned as two integers. bounds[boundsOffset] == width, bounds[boundsOffset+1] == height. |
| boundsOffset | the offset into the array where the bounds will be stored. |
| rgb565 | the destination 565 buffer. May be null, and may also be larger than or smaller than the amount of space required to store the image data. If rgb565 is smaller than the amount of space required to store the image data, then any excess image data will be discarded. |
Throws
| IllegalArgumentException | if the JPEG data is not a valid JPEG image, or if jpegData is null, or jpegDataOffset < 0, or jpegDataOffset + jpegDataLength > jpegData.length, or or bounds.length < 2, boundsOffset < 0, boundsOffset > bounds.length - 2. /** Decodes a JPEG encoded image into a buffer. |

| IllegalArgumentException | if the JPEG data is not a valid JPEG image. |
