Function Documentation

◆ arm_2dp_gray8_filter_iir_blur()

arm_fsm_rt_t arm_2dp_gray8_filter_iir_blur ( arm_2d_filter_iir_blur_descriptor_t *  ptOP,
const arm_2d_tile_t *  ptTarget,
const arm_2d_region_t *  ptRegion,
uint8_t  chBlurDegree 
)

Apply IIR blur to a specified region on the target tile.

Parameters
[in]ptOPthe control block, NULL means using the default control block
[in]ptTargetthe target tile
[in]ptRegionthe target region
[in]chBlurDegreethe blur degree,
Note
- 0~127 works as generic anti-alias, and
  • 128~239 works as blur
Returns
arm_fsm_rt_t the operations result

arm_fsm_rt_t arm_2dp_gray8_filter_iir_blur_depose ( arm_2d_filter_iir_blur_descriptor_t *  ptOP)

Release the resource used by the given IIR blur.

Parameters
[in]ptOPthe control block, NULL means using the default control block
Returns
arm_fsm_rt_t the operations result

◆ arm_2dp_rgb565_filter_iir_blur()

arm_fsm_rt_t arm_2dp_rgb565_filter_iir_blur ( arm_2d_filter_iir_blur_descriptor_t *  ptOP,
const arm_2d_tile_t *  ptTarget,
const arm_2d_region_t *  ptRegion,
uint8_t  chBlurDegree 
)

Apply IIR blur to a specified region on the target tile.

Parameters
[in]ptOPthe control block, NULL means using the default control block
