vg_lite_radial_gradient_t structure

This structure defines the application of the radial gradient to fill a path. (from November 2020, requires GC355 or GC555 hardware).

Used in radial gradient functions: vg_lite_draw_grad, vg_lite_set_radial_grad, vg_lite_update_radial_grad, vg_lite_get_radial_grad, vg_lite_clear_radial_grad.

vg_lite_radial_gradient_t member	Type	Description
count	vg_lite_uint32_t	Count of colors, up to 256
matrix	vg_lite_matrix_t	Structure that specifies the transform matrix for the gradient
image	vg_lite_buffer_t	Structure that specifies the image for rendering as a gradient pattern
radial_grad	vg_lite_radial_gradient_parameter_t	Structure that specifies the location of the gradient’s center point (cx, cy), focal point(fx, fy) and radius(r)
ramp_length	vg_lite_uint32_t	Color ramp parameters for gradient paints provided to the driver
color_ramp[VLC_MAX_COLOR_RAMP_STOPS]	vg_lite_color_ramp_t	Structure that specifies the color ramp
converted_length	vg_lite_uint32_t	Converted internal color ramp.
converted_ramp[VLC_MAX_COLOR_RAMP_STOPS+2]	vg_lite_color_ramp_t	Structure that specifies the internal color ramp
pre_multiplied	vg_lite_uint32_t	If this value is set to 1, the color value of color_ramp will be multiplied by the alpha value of color_ramp.
spread_mode	vg_lite_radial_gradient_spreadmode_t	Enum that specifies the tiling mode, which is applied to the pixels out of the image after transformation
