Me. Art filter
Art filter is like an artist who is familiar with all kinds of painting styles and techniques. It can turn a plain image into a masterpiece of a master, and the painting form is eclectic. Can produce oil painting, watercolor painting, pencil painting, chalk painting, gouache painting and other artistic effects.
(1) colored pencil (colored pencil)
This filter simulates drawing an image with a colored pencil on a solid background. The main edges are preserved and have a rough shadow appearance, and the pure background color is displayed through a smoother area.
Pencil width: We can adjust the pencil width by using stroke bars.
Stroke pressure: you can adjust the stroke pressure in the current drawing direction.
(Paper brightness) Paper brightness can be adjusted.

Brush Details: Adjust the details of the current image brush.
(Shadow Intensity): Adjust the darkness and brightness of the current image brush.
Texture: Adjust the degree of watercolor effect of the current image. (The value is only 3)
Second, blur filter.
The blur filter group is mainly used to reduce the color difference between adjacent pixels to varying degrees, so that the image has a soft and fuzzy effect.
(1) fuzzy
This filter will blur the image. It can remove obvious edges or very gentle soft edges in an image, just like adding a soft lens in front of a camera lens.
(2) More fuzzy (further fuzzy)
It has the same effect as the blur filter, but the intensity is increased to three or four times.
(3) Gaussian blur (Gaussian blur)
The filter can quickly blur the image according to the numerical value, producing a good hazy effect. Gaussian refers to the bell curve generated by weighted average of pixels.
When Gaussian blur is selected, a check box will pop up. At the bottom of the dialog box, we can adjust the blur degree of the current image by dragging the scroll bar, or we can enter the radius (R):2 pixels.
(4) Motion blur (motion blur)
This filter imitates the technology of shooting moving objects, and produces motion blur effect through the linear displacement of box elements in a certain direction.
Dynamic blur is to stretch the pixels of the current image to both sides, and we can adjust the angle in the dialog box. And stretching distance. As mentioned above, drag the bar at the bottom of the dialog box to adjust the blur level and enter a numerical value.
(5) Radial blur (radial blur)
This filter can produce a radioactive blur effect. That is to simulate the blur effect caused by the camera moving back and forth or rotating.
(fuzzy method) fuzzy method:
Rotation: it blurs the image of my current document from the center, imitating the texture of rotation nesting.
Zoom: the image of the current file appears from the zoom effect, and it is especially good to do some dynamic characters.
(quality) fuzzy quality: draft: fuzzy effect is average.
Good: The blur effect is better.
Best: the blur effect is particularly good.
(6) Intelligent fuzzy (special fuzzy)
This filter can find the edge of the image and blur the area within the boundary line. Its advantage is that it can blur the image and still make the image have a clear boundary, which is helpful to remove the particles and noise in the image tone.
After the special fuzzy dialog box pops up, the command is displayed as follows:
(Radius) Radius: Blur by radius.
Threshold: Adjust the blur level of my current image.
Quality: low: fuzzy quality is slightly lower.
; ; Chinese: The fuzzy quality is the middle value.
High: Fuzzy quality is particularly high.
Mode: Normal: the default setting of the computer.

Overlay Edge: This mode will make my current image into one; ; The edges of some textures will turn white.
Third, the brush stroke filter
Brush stroke filter mainly simulates different brushes or ink pens to draw pictures and produce painting effects.
(1) Stress Edge (Enhanced Edge)
This filter is similar to the effect of drawing the boundary of the image with colored strokes, which makes the image have more obvious boundaries. Some people call it the "bold border" filter.
(Edge Width): Adjust the width of the edge enhancement of the current image.
Edge brightness: adjust the brightness of the enhanced edge of the current image.
Smoothness: Adjust the smoothness of the enhanced edge of the current image.
(2) Angular strokes (angular lines)
The filter can generate images with oblique strokes, similar to diagonal lines drawn with oil paints on canvas with a brush at a certain angle. The lines are slender, the strokes are sharp, and the effect is better. Some people also call it a "slash" filter.
Direction balance: adjust the direction control of the angle line.
(Stroke Length): Controls the length of the line.
(Sharpness) Sharpness: Adjust the sharpness. If the value is higher, it will make the image brighter and the effect will be blunt. The smaller the value, the softer the angle line.
(3) Cross hatching (hatching)
This filter can produce a cross-hair grid-like image, just like the effect when we draw cross-hair on a rough canvas with a brush, giving people a sense of chaos. Some people call it the "Crosshair Diagonal" filter.
Stroke length: Adjust the length of the hatch.
Sharpness: Controls the sharpness of shadow lines. The larger the value, the stiffer the effect. The smaller the value, the softer the effect.
(Intensity) Intensity: Adjust the intensity of the shadow line to make the pixel color brighter.
(4) Dark strokes (dark lines)
The filter draws dark areas in the image with short and dense lines, and draws bright areas in the image with long and white lines, thus producing a strong black shadow effect.

(Black Density) Black Density: Adjust the black density of the current document image.
(White Density) White Density: Adjust the white density of the current document image.
(5) Ink Profile (Overview of Ink)

(7) Splash strokes (painted color strokes)
This filter can produce an effect of spraying water in a certain direction, and the picture looks like it has been washed by rain. Some people call it "spray" filter.
(Stroke Length) Line Length: Adjust the ink-jet line length of the current document image.
Jet radius: adjust the degree of jet radius of the current document image. The larger the value, the worse the splash effect.
Stroke direction: right diagonal: diagonal 45 degrees.

Left diagonal: diagonal -45 degrees.
Vertical: The stroke direction is vertical from top to bottom.
(8) Sumi-e (soot ink)
The filter can give a general description of the image by calculating the distribution of pixel values in the image, and then produce the effect of painting on rice paper with a brush filled with black ink. It can make images with words produce more special effects, so some people call it "calligraphy" filter.
(Stroke Width): Adjust the stroke width of the current document image.
Stroke Pressure: Adjust the stroke pressure of the current document image. The larger the value, the stiffer the image.
Contrast: Adjust the brightness contrast of the current document image.
Fourth, twist the filter.
Deformation filters geometrically deform images to create three-dimensional or other deformation effects. These filters usually take up more memory space at run time.
(9) Diffuse glow
Filters can produce the effect that the image is baked by hot objects such as stoves, and the brighter areas in the original image will be infected by the background color, and the lighting effect will change. Some people call it "diffuse light"
Granularity: Adjust the granularity of diffused light of the current document image.
(Luminous Amount): Adjust the luminous amount of the current document image.
(Clear Amount): Adjust the image granularity of the current file.
Fourth, replace (replace the filter)
This filter is a complicated filter. It can displace the image, and the displacement effect depends not only on the set parameters, but also on the selection of displacement diagram (that is, displacement diagram). It will read the chromaticity values of pixels in the displacement map to determine the displacement and process each pixel in the current image.
The displacement map must be an image in PSD format.
(Horizontal scale): Adjust the horizontal scale of displacement filter.
Vertical scale: adjust the vertical scale of displacement filter.
(Displacement diagram) Displacement diagram:
Stretch to Fit: Stretch the current image to a suitable position.

(2) Ocean Ripple
This filter adds randomly spaced ripples to the image surface, making the image look like it is underwater.
Ripple Size: Adjust the ripple size of the current document image.
Ripple amplitude: adjust the ripple amplitude of the current document image.
(3) Shrinkage (extrusion)
Filters can simulate the effect of expansion or extrusion, shrink or enlarge the selected area in the image, and make the image squeeze inward or outward. For example, it can be used to correct a photo image to reduce or increase a certain part of a person (such as nose or lips).
After the extrusion dialog box pops up, there is a thumbnail and a command at the bottom. We can drag the paddle to adjust the degree of extrusion. Note: Center 0 is the standard for stretching. If you drag the paddle to the right, you will get a squeezing effect; If you drag the paddle to the left, you will get a prominent effect by putting a-sign before the input value.
(4) Polar coordinates (Polar coordinates (5))
The working principle of this filter is to redraw the pixels in the image so that it can be converted from rectangular coordinate system to polar coordinate system, or from polar coordinate system to rectangular coordinate system.
(Rectangular to polar coordinates) Plane coordinates to polar coordinates: rotate in polar coordinates with the center point in the middle of the image.
(Polar coordinate to right angle) Polar coordinate to plane coordinate: Centered at the bottom of the image, and then rotated.
(6) ripple
This filter is similar to the effect of waves, and it can also produce the ripple effect of water waves. It's just a simple operation.
After the ripple dialog box pops up, there is a pick at the bottom of the dialog box. We can use the mouse to drag this paddle to adjust the waviness. The next command to stroke the bottom of the pole is to adjust the degree of ripple size.
(Size) Size: (small): medium: large: large.
(7) Shear (Shear (8) Change)
The filter can distort the image according to the vertical curve set by the user in the dialog box, resulting in a more complex distortion effect.
When adjusting the thumbnail above, we can add points, subtract points and add points: double-click the line on the thumbnail. Minus point: click the left mouse button, hold it down and drag it out.
Fold backward (around): If this command is selected, the thumbnail above will be supplemented if it exceeds the image when it is adjusted.
(Duplicate edge pixels): If this command is selected, the image will not be supplemented if it exceeds the thumbnail.
(9) Spherize
Filters can enlarge the image area, realize spheroidization, and form an effect similar to sticking an image on the surface of a sphere or cylinder.
After the extrusion dialog box pops up, there is a thumbnail and a command at the bottom, and we can drag the paddle to adjust the sphere. Note: Spheroidization is based on center 0. Drag the paddle to the left to get the squeezing effect, and drag the paddle to the right to get the spherical convex effect.
(10) rotation (rotational torsion)
This filter can make the image rotate like a wind wheel, and even produce a spiral distortion effect that places the image in the center of a large vortex.
