Symbol layer type: It’s possible to use Centroid Fill, Gradient Fill, Line Pattern Fill,.In case of negative values, black is displayed. Subtract: This blend mode simply subtracts pixel values of one layer from the other.Blending with black produces no change, as the difference with all colors is zero. Difference: Difference subtracts the top pixel from the bottom pixel, or the other way around, to always get a positive value.It’s supposed to emulate projecting a very intense light onto an image. Hard light: Hard light is also very similar to the overlay mode.This is supposed to emulate shining a soft light onto an image. Soft light: This is very similar to overlay, but instead of using multiply/screen it uses color burn/dodge.In the resulting picture, light parts become lighter and dark parts become darker.
Overlay: This mode combines the multiply and screen blending modes.Burn can be used to tweak and colorise underlying layers. Burn: Darker colors in the top layer cause the underlying layers to darken.Multiply: Here, the numbers for each pixel of the top layer are multiplied with the corresponding pixels for the bottom layer.Like lighten, the results tend to be jagged and harsh. Darken: This creates a resultant pixel that retains the smallest components of the foreground and background pixels.This mode is suitable for highlighting features. In case of values above one (in the case of RGB), white is displayed. Addition: This blend mode simply adds pixel values of one layer with the other.This works best if the top pixels aren’t too bright otherwise the effect is too extreme. So, brighter top pixels cause the saturation and brightness of the underlying pixels to increase. Dodge: Dodge will brighten and saturate underlying pixels based on the lightness of the top pixel.This mode is most useful for mixing the texture of one layer with another layer (e.g., you can use a hillshade to texture another layer). Screen: Light pixels from the source are painted over the destination, while dark pixels are not.Be aware that the results tend to be jagged and harsh. Lighten: This selects the maximum of each component from the foreground and background pixels.Normal: This is the standard blend mode, which uses the alpha channel of the top pixel to blend with the pixel beneath it.The pixels of your overlaying and underlaying layers are mixed Previously only know from graphics programs. Layer blending mode and Feature blending mode: You can achieve special rendering effects with these tools that you may.You can also make a precise definition of the percentage of visibility in the the menu beside the slider. Use the slider to adapt the visibility of your vector layer to your needs. Layer transparency : You can make the underlying layer in the map canvas.
