1# OhosPixelMapInfos 2 3 4## Overview 5 6The **OhosPixelMapInfos** struct defines the information about a pixel map. 7 8**System capability**: SystemCapability.Multimedia.Image 9 10**Since**: 10 11 12**Related module**: [Image](image.md) 13 14 15## Summary 16 17 18### Member Variables 19 20| Name| Description| 21| -------- | -------- | 22| [width](#width) | Image width, in pixels.| 23| [height](#height) | Image height, in pixels.| 24| [rowSize](#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.| 25| [pixelFormat](#pixelformat) | Pixel format.| 26 27 28## Member Variable Description 29 30 31### height 32 33``` 34uint32_t OhosPixelMapInfos::height 35``` 36 37**Description** 38 39Image height, in pixels. 40 41 42### pixelFormat 43 44``` 45int32_t OhosPixelMapInfos::pixelFormat 46``` 47 48**Description** 49 50Pixel format. 51 52 53### rowSize 54 55``` 56uint32_t OhosPixelMapInfos::rowSize 57``` 58 59**Description** 60 61Number of bytes per row. 62 63In the case of DMA, the formula is as follows: Image width x Roundup(64 x Number of bytes per pixel).
