SK-TDA4VM: The TIOVX application with respect to vxQueryImage always captures a multiple of 16B of the image data size

Hi team,

Regarding the application of the function vxQueryImage get Image Properties for TIOVX, when the customer creates a window with a width of 5, height of 1, and pixel format of VX_DF_image_U8, when the program is compiled and executed on the SK-TDA4VM development board, the console prints an image size of 16B. 

And when creating the following image, the image size returned via vxQueryImage is all 16B:

vx_image image1 = vxCreateImage(context, 1, 1,VX_DF_IMAGE_U8 )

vx_image image2= vxCreateImage(context, 2, 1,VX_DF_IMAGE_U8 )

The size of the image should be width * height * pixel size, right? But why is the result always a multiple of 16 bytes? 

Could you help look into this case? Thanks.

Best Regards,

Cherry
