Hello,
i'm using the DM642 EVM and i try to copy image data from a memory maintained by the vport mini-driver to another location with the dat_copy2d function:
transIDS1 = DAT_copy2d(DAT_1D2D, (void *) &YPtr[0], (void *) &YSlice1_opt_v2[1450], 720, 3, 724);
YPtr is an 576x720 array of 8 bit element and YSlice1_opt_v2 is an 7x724 array of 8 bit elements. The objective is to copy three lines from the center of YPtr to YSlice1_opt_v2.
If first 3 lines YPtr looks like this:
1 2 3 . . . 3 2 1
1 2 3 . . . 3 2 1
1 2 3 . . . 3 2 1
YSlice1_opt_v2 shall looks like this:
0 0 0 0 0 . . . 0 0 0 0 0
0 0 0 0 0 . . . 0 0 0 0 0
0 0 1 2 3 . . . 3 2 1 0 0
0 0 1 2 3 . . . 3 2 1 0 0
0 0 1 2 3 . . . 3 2 1 0 0
0 0 0 0 0 . . . 0 0 0 0 0
0 0 0 0 0 . . . 0 0 0 0 0
Can this be achive with dat_copy2d and is there a better explanation than in spru401j? The way i understand the functionality of dat_copy2d seems to be wrong.
Thanks for help!
Martin
