Mixed mode description

normal Edit or draw each pixel , Make it a result color . This is the default mode .（ When working with bitmap images or indexed color images ,“ normal ” Patterns are also called threshold .）

dissolution Edit or draw each pixel , Make it a result color . however , According to the opacity of any pixel position , The resulting color is randomly replaced by the pixels of the primary color or mixed color .

behind Edit or paint only in the transparent part of the layer . This mode is only available when “ Lock the transparent area ” Used in the layer of , It is similar to painting on the back of transparent area of transparent paper .

eliminate Edit or draw each pixel , Make it transparent . This mode can be used for shape tools （ When a filled area is selected ）、 Paint bucket tools 、 Brush Tool 、 Pencil Tool 、“ fill ” Command and “ Stroke ” command . You must be in the deselected “ Lock the transparent area ” This mode can only be used in layers of .

Darken Check the color information in each channel , And select the darker color in the base color or mixed color as the result color . Pixels brighter than the blend color will be replaced , Pixels darker than the blend color remain unchanged .

Multiply the positive Check the color information in each channel , And the base color and the mixed color are superimposed . The result color is always a darker color . Any color is superimposed with black positives to produce black . Any color and white positives remain the same . When you paint in a color other than black or white , The continuous stroke drawn by the painting tool produces a gradually darkening color . This is similar to drawing on an image using multiple marker pens .

The color deepened Check the color information in each channel , By increasing the contrast between the two, the primary color is darkened to reflect the mixed color . It does not change when mixed with white .

Linear deepening Check the color information in each channel , And darken the base color by reducing the brightness to reflect the mixed color . It does not change when mixed with white .

Brighten Check the color information in each channel , And select the brighter color in the base color or mixed color as the result color . Pixels darker than the blend color are replaced , Pixels brighter than the blended color remain unchanged .

Filter color Look at the color information for each channel , The complementary color of the mixed color and the base color are superimposed on the positive film . The resulting color is always a lighter color . The color remains the same when filtering with black . Filtering with white will produce white . This effect is similar to multiple photographic slides projected on top of each other .

Color fades Check the color information in each channel , By reducing the contrast between them, the primary color is lightened to reflect the mixed color . Mixing with black doesn't change .

Linear dilution （ add to ） Check the color information in each channel , By increasing the brightness, the base color is brightened to reflect the mixed color . Mixing with black doesn't change .

superposition Make a positive overlay or filter on the color , Depending on the primary color . Patterns or colors are superimposed on existing pixels , At the same time, keep the light and dark contrast of the primary color . Do not replace the primary color , But the primary color is mixed with the mixed color to reflect the brightness or darkness of the primary color .

Soft light To darken or brighten a color , Depending on the blend color . This effect is similar to a divergent Spotlight shining on an image . If you mix colors （ The light source ） Than 50% Gray light , Then the image becomes bright , It's like being diluted . If you mix colors （ The light source ） Than 50% Grey dark , The image darkens , It's like being deepened . Color with pure black or pure white , Can produce areas that are significantly darker or brighter , But it cannot produce pure black or pure white .

A strong light Make a positive overlay or filter on the color , Depending on the blend color . This effect is similar to the dazzling spotlight on the image . If you mix colors （ The light source ） Than 50% Gray light , Then the image becomes bright , Just like the filtered effect . This is useful for adding highlights to images . If you mix colors （ The light source ） Than 50% Grey dark , The image darkens , It's like the effect of a positive film after it is superimposed . This is useful for adding shadows to images . Coloring with pure black or pure white will produce pure black or pure white .

Light up Darken or fade colors by increasing or decreasing contrast , Depending on the blend color . If you mix colors （ The light source ） Than 50% Gray light , The image is lightened by reducing the contrast . If the mixing color ratio 50% Grey dark , Darken the image by increasing the contrast .

Linear light Darken or lighten colors by decreasing or increasing brightness , Depending on the blend color . If you mix colors （ The light source ） Than 50% Gray light , The image is brightened by increasing the brightness . If the mixing color ratio 50% Grey dark , The image is darkened by decreasing the brightness .

Spot light Replace the color according to the mixed color . If you mix colors （ The light source ） Than 50% Gray light , Replace pixels darker than the mixed color , Without changing the pixels that are brighter than the blended color . If the mixing color ratio 50% Grey dark , Replace pixels brighter than the mixed color , Pixels darker than the blend color remain unchanged . This is useful for adding special effects to images .

Solid color mixing Will mix colors of red 、 Green and blue channel values are added to the base color RGB value . If the sum of the results of the channels is greater than or equal to 255, Then the value is 255; If it is less than 255, Then the value is 0. therefore , The red color of all mixed pixels 、 The green and blue channel values are either 0, Or 255. This mode changes all pixels to the primary additive color （ Red 、 Green or blue ）、 White or black .
