mlib_VideoColorBlendABGR_Inp, mlib_VideoColorBlendABGR_ResetAlpha_Inp - in-place image blend SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> void mlib_VideoColorBlendABGR_Inp(mlib_u32 *src1dst, const mlib_u32 *src2,mlib_s32 src1dst_w, mlib_s32 src1dst_h,mlib_s32 src2_w, mlib_s32 src2_h,mlib_s32 src2_x, mlib_s32 src2_y,mlib_s32 src1dst_lb, mlib_s32 src2_lb,mlib_blend src1dst_blend, mlib_blend src2_blend); void mlib_VideoColorBlendABGR_ResetAlpha_Inp(mlib_u32 *src1dst, const mlib_u32 *src2, mlib_s32 src1dst_w, mlib_s32 src1dst_h, mlib_s32 src2_w, mlib_s32 src2_h, mlib_s32 src2_x, mlib_s32 src2_y, mlib_s32 src1dst_lb, mlib_s32 src2_lb, mlib_blend src1dst_blend, mlib_blend src2_blend); DESCRIPTION
The functions use the following equation for blending images: src1dst = (src1dst * src1dst_blend) + (src2 * src2_blend) The two multi-banded source images (src1dst and src2) are blended together and the result is stored in src1dst. src1dst_blend specifies the blend function to be applied to the src1dst image and src2_blend specifies the blend function to be applied to the src2 image. src2_x and src2_y specify position of src2 relative to the upper-left corner of src1dst. src2 is clipped to the boundaries of src1dst, if needed. Possible blend functions are: MLIB_BLEND_ZERO MLIB_BLEND_ONE MLIB_BLEND_SRC_ALPHA MLIB_BLEND_ONE_MINUS_SRC_ALPHA MLIB_BLEND_DST_ALPHA MLIB_BLEND_ONE_MINUS_DST_ALPHA MLIB_BLEND_DST_ALPHA is the alpha band of image src1 scaled to the range 0 to 1. MLIB_BLEND_SRC_ALPHA is the alpha band of image src2 scaled to the range 0 to 1. The output pixel bands are clamped to the range 0 to 255. For the mlib_VideoColorBlendABGR_ResetAlpha_Inp() function, the alpha value of every pixel in destination image is set to 0 after blending is complete. PARAMETERS
Each of the functions takes the following arguments: src1dst Pointer to 1st input image (also dest. image). src2 Pointer to 2nd input image. src1dst_w src1dst image width in pixels. src1dst_h src1dst image height in rows. src2_w src2 image width in pixels. src2_h src2 image height in rows. src2_x src2 horizontal displacement (in pixels), relative to the upper-left corner of src1dst. src2_y src2 vertical displacement (in rows), relative to the upper-left corner of src1dst. src1dst_lb Linebytes for src1dst image. src2_lb Linebytes for src2 image. src1dst_blend Blend function for src1dst image. src2_blend Blend function for src2 image. RETURN VALUES
None. ATTRIBUTES
