Member | Value | Description |
---|---|---|
MST_Additive | 3 | Pixel values are added to the pixels in the existing image. |
MST_Alpha_BackGround_Over_ForeGround | 15 | The background image alpha channel determines which pixels are transparent and opaque. Effectively, the background alpha channel is negated and applied with the net result that the opaque background pixel will show through and the transparent pixel will allow the foreground image to show. |
MST_Alpha_ForeGround_Over_BackGround | 14 | The normal way of viewing a merged alpha image. The alpha channel in the foreground image is used to blend the two images together. The alpha channel contains information as to which pixels are opaque and which pixels are transparent in the image, and the degree of transparency. An opaque pixel in the foreground will hide the pixel in the background image. Likewise, a transparent pixel in the foreground image will let the background pixel show through. |
MST_Alpha_Least_Opaque | 17 | The least opaque pixel value is chosen from the foreground and background alpha channels and is used for the foreground image. |
MST_Alpha_Most_Opaque | 16 | The most opaque pixel value is chosen from the foreground and background alpha channels and is used for the foreground image. |
MST_IfDarker | 1 | Merges only pixels darker than the ones in the existing image. |
MST_IfLighter | 2 | Merges only pixels lighter than the ones in the existing image. |
MST_Normal | 0 | Pixels are merged with the existing image. |
MST_Subtractive | 4 | Pixel values are subtracted from the pixels in the existing image. |
MST_Superimpose | 5 | The image is superimposed onto the existing image. high merge percentage determines the intensity of the superimposition. |
MST_Superimpose_BottomToTop | 11 | The image is superimposed onto the existing image. This produces a fading effect where the bottom of the superimposed image is lighter than the top. Here too, merge merge percentage determines intensity of superimposition. |
MST_Superimpose_HorizFromCenter | 12 | The image is superimposed onto the existing image. This produces a fading effect where the top and bottom of the superimposed image are lighter than the center. Merge merge percentage determines the intensity range of the superimposition. |
MST_Superimpose_HorizToCenter | 13 | The image is superimposed onto the existing image. This produces a fading effect where the center of the superimposed image is lighter than the top and bottom. High or low merge percentage determines the intensity range of the superimposition. |
MST_Superimpose_LeftToRight | 6 | The image is superimposed onto the existing image. This produces a fading effect where the left side of the superimposed image is lighter than the right side. The high or low merge percentage determines the intensity range of the superimposition. |
MST_Superimpose_RightToLeft | 7 | The image is superimposed onto the existing image. This produces a fading effect where the right side of the superimposed image is lighter than the left side. The high or low merge percentage determines the intensity range of the superimposition. |
MST_Superimpose_TopToBottom | 10 | The image is superimposed onto the existing image. This produces a fading effect where the top of the superimposed image is lighter than the bottom. Merge percentage determines intensity of superimposition. |
MST_Superimpose_VerticalFromCenter | 9 | Superimpose Vertical from Center The image is superimposed onto the existing image. This produces a fading effect where the center of the superimposed image is lighter than the right and left sides. Merge percentage determines intensity of superimposition. |
MST_Superimpose_VerticalToCenter | 8 | The image is superimposed onto the existing image. This produces a fading effect where the right and left sides of the superimposed image are lighter than the center. Merge percentage determines intensity range of the superimposition. |
