20| Name| Description| 
21| -------- | -------- |
22| uint32_t [width](#width) | Image width, in pixels. | 
23| uint32_t [height](#height) | Image height, in pixels. | 
24| uint32_t [rowSize](#rowsize) | Number of bytes per row. In the case of Direct Memory Access (DMA), the formula is as follows: Image width x Roundup(256 x Number of bytes per pixel). (The roundup means that each row is automatically padded.) In the case of other types of memory, the formula is as follows: Image width x Number of bytes per pixel. | 
25| int32_t [pixelFormat](#pixelformat) | Pixel format. |
