Member Variable Description

height

uint32_t OhosPixelMapInfos::height

Description

Image height, in pixels.

pixelFormat

int32_t OhosPixelMapInfos::pixelFormat

Description

Pixel format.

rowSize

uint32_t OhosPixelMapInfos::rowSize

Description

Number of bytes that each row of the image occupies in the memory.

In the case of DMA, the formula is as follows: Image width x Number of bytes of each pixel + Number of padding bytes at the end of each row. In the case of other types of memory, the formula is as follows: Image width x Number of bytes of each pixel.

width

uint32_t OhosPixelMapInfos::width

Description

Image width, in pixels.
