NVCVStatus nvcvImageCalcRequirements(int32_t width, int32_t height, NVCVImageFormat format, int32_t baseAddrAlignment, int32_t rowAddrAlignment, NVCVImageRequirements *reqs)

Calculates the resource requirements needed to create an image.

Parameters:

• width, height – [in] Image dimensions.

  • Width and height must be > 0.

• format – [in] Image format.

  • Must not be NVCV_IMAGE_FORMAT_NONE.

• baseAddrAlignment – [in] Alignment, in bytes, of the requested memory buffer. If 0, use a default suitable for optimized memory access. The used alignment is at least the given value.

  • If different from 0, it must be a power-of-two.

• rowAddrAlignment – [in] Alignment, in bytes, of each image’s row address. If 0, use a default suitable for optimized memory access. The used alignment is at least the given value. Pass 1 for fully packed rows, i.e., no padding at the end of each row.

  • If different from 0, it must be a power-of-two.

• reqs – [out] Where the image requirements will be written to.

  • Must not be NULL.

Return values:

• NVCV_ERROR_INVALID_ARGUMENT – Some parameter is outside valid range.

• NVCV_SUCCESS – Operation executed successfully.
