// [TAG] EIP59139
// [Category] Bug Fix
// [Severity] Normal
// [Symptom] Jpeg image with the resolution 1366x768 is not displayed in
// Screen resolution 1366x768.
// [RootCause] Jepg Algorithem does the decoding in 16 pixel boudary. As
// 1366 is not in 16 bit boundary the image width is returned as 1376 to
// make 16bit boundary.
// [Solution] Once decoded the Blt buffer is formed with orginal
// resolution from the image.

// Procedure: ConvertJPEGToUgaBlt
//
// Description: Decode the JPEG and store the output in UGA format. The
// JPEG images are stored in 16X16 blocks. Hence Buffer will
// require width and hieght that are equal to or more than
// the actual width and hieght. Buffer Width and Height will
// be the lowest multipe of 16 that is equal to or greater than
// the actual width and height.
// Eg: For decoding an image with Actual sizes being 17X33 will
// require a buffer of 32X48.
//
// Input: IN VOID *JPEGImage - Pointer to the memory that has the
// JPEG Image that need to be decoded.
// IN UINT32 JPEGImageSize - Size of the JPEG Image
// IN OUT VOID **UgaBlt - Two cases
// Case 1: Memory is expected to be allocated by the callee.
// Address provided as input should be NULL.
// pointer that will recieve the address of the UGA buffer.
// The buffer is allocated by callee.
// This buffer need to be freed by the caller.
// Case 2: Memory is allocated by the caller
// IN OUT UINT32 *UgaBltSize - Pointer that stores Size of UgaBlt
// in bytes. This will be treated as an input. This should have
// value ZERO for Case 2 above.
// OUT UINT32 *PixelHeight - Height of UgaBlt/JPEG Image in pixels
// OUT UINT32 *PixelWidth - Width of UgaBlt/JPEG Image in pixels
// OUT UINT32 *pun32BufferWidth - Width of UgaBlt/JPEG Buffer
//
// Output: EFI_SUCCESS - The image was successfully decoded and placed in the buffer
// EFI_UNSUPPORTED
// EFI_BUFFER_TOO_SMALL
// EFI_OUT_OF_RESOURCES
