Summary
Member Variables
| Name | Description |
|---|---|
| width | Image width, in pixels. |
| height | Image height, in pixels. |
| rowSize | Number of bytes per row. In the case of Direct Memory Access (DMA), the formula is as follows: Image width x Roundup(64 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. |
| pixelFormat | Pixel format. |
