A detailed explanation of the filter function of Photoshop (Ii.)

Iv. Distort (Twisted) filter

Warp filters distort the image to create three-dimensional or other deformation effects. These filters typically consume more memory space at run time.

(9) Diffuse Glow (diffuse light)

The filter can produce an image by the stove and other hot objects baked and formed effect, the original image of the brighter areas will be infected with the background color, lighting effects change. Others call it "diffuse light."

(graininess) Granularity: Adjusts the size of the current file image to diffuse the brightness.

(Glow Amount) luminescence: The amount of light that adjusts the current file image.

(clear Amount) Purge Quantity: Adjust the number of current file image granularity

Four, displace (displacement filter)

The filter is a more complex filter. It can make the image displacement, the displacement effect depends not only on the set parameters, but also on the displacement diagram (that is, displacement map) selection. It reads the chroma values of the pixels in the displacement graph to determine the amount of displacement and handles the individual pixels in the current image.

The displacement diagram must be a PSD-formatted image.

(horizontal Scale) Horizontal ratio: Adjusts the proportions of the displacement filter level.

(Vertical Scale) Vertical ratio: Adjust the displacement filter the proportion of water sag.

(Displacement map) displacement diagram:

Stretch for (Stretch to fit): Extend the current image to a suitable location.

Collage (Tile): The effect of tiling the current image.

(Undefined Areas) undefined zone:

Retrace (Wrap Around): The current image is divided into fragments, imitation fold into the texture.

Repeat Edge pixel (Repeat edge Pixdls): Pixel of duplicate edge.

(1) Glass (glass)

The filter can simulate the effect of viewing the image through the glass, and can produce different deformation effects according to the glass texture chosen by the user.

(distortion) Twist degree: Adjusts the degree to which the current file image is distorted.

(smoothness) Smoothness: Adjusts the smoothness of the current file image glass effect.

(texture) Texture: block (Blocks): Imitate the texture of the block.

Canvas (Canvas): Imitates the texture of the canvas.

Frosting (frosted): mimics the texture of frosting.

Small lens (Tiny Lens): Imitate the texture of small lenses.

Load texture (load texture): Loads a file from a computer store into the current image as a texture.

(scaling) Scaling: Adjusts the scaling of various effects of the current file image.

(Invert) Reverse phase: The direction of changing textures and glass effects.

(2) Ocean ripple (Ocean Ripple)

The filter adds a random-spaced ripple to the image surface, making the image appear to be under water.

(ripple size) Ripple size: Adjusts the size of the current file image ripple.

(ripple magnitude) ripple amplitude: The extent to which the current file image ripple amplitude is adjusted.

(3) Pinch (extrusion)

The filter can simulate the effect of expansion or extrusion, can reduce or enlarge the selection of the image, so that the image produced inward or outward extrusion effect. For example, you can use it to correct a photo image to reduce or enlarge a part of a character (such as a nose or lip).

After the extrusion dialog box pops up, there is a thumbnail and a command at the bottom so we can drag the stroke to adjust the extrusion. Note: Squeeze to center 0 as the standard, if you drag the rod to the right, it will form the effect of extrusion, if you drag the bar to the left, the input value of the front plus a-number, then will form a bulge effect.

(4) Polar coordinates (polar coordinates (5))

The filter works by redrawing the pixels in the image so that they are converted from a rectangular coordinate system to a polar coordinate system, or from a polar coordinate system to a rectangular coordinate system.

(rectangular to Polar) plane coordinates to polar coordinates: it is a polar coordinate rotation of the center point of the image.

(Polar to rectangular) polar coordinates to plane coordinates: it is centered and rotated by the bottom of the image.

(6) Ripple (ripple)

The filter is similar to the effect of a wave, and can also produce ripple effects of ripples. It's simple to operate.

After the pop-up Ripple dialog box, there is a stroke at the bottom of the dialog box, we can use the mouse to drag the stroke to adjust the ripple level. The command of the force at the bottom of the rod is the degree of adjustment of the ripple size.

(size) Size: (Small): Small Ripple (Medium): Medium Ripple (Large): Large ripple

(7) Shear (Tangent (8) change)

The filter can distort the image based on the vertical curve set by the user in the dialog box, resulting in a more complex twist.

When adjusting the thumbnail above, we can add some adjustments, reduce the point adjustment, add dots: Double click on the line on the thumbnail. Minus point: Click the left mouse button, press and hold the point to drag outside.

(Wrap Around) Retrace: This command is selected, then it will be supplemented if the image is exceeded when adjusting the thumbnail above.

(Repeat edge Pixels) Repeat edge pixels: This command is selected and will not be replenished when the thumbnail is resized if the image is exceeded.

(9) Spherize (spherical)

The filter enables the image area to expand and be spherical, creating a similar effect that pastes the image on the surface of the 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 stroke to adjust the sphere. Note: Spherical to center 0 as the standard, if you drag the rod to the left, it will form the effect of extrusion, if you drag the rod to the right, it will form a spherical convex effect.

(a) Twirl (rotational distortion)

The filter enables the image to produce an effect similar to the rotation of the wind wheel, and even produces a helical twist that places the image at the center of a large vortex.

Number of generators generators: The larger the number, the more shadows will appear inside the image.

(wavelength) Wavelength:

Min: Enter a value in the minimum to control the end position of the largest stroke drag.

Max (max): The maximum output value can control the end position of the minimum stroke drag.

(amplitude) Amplitude:

Min: Enter a value in the minimum to control the end position of the maximum stroke drag.

Max (max): Enter a value in the maximum to control the end position of the minimum stroke drag.

(Scale) Ratio: Level (HORIZ): To the level of the variable Formation degree.

Vertical (Vert): with vertical to variable formation degree.

(type) Type: Sine (Sine): formed by sinusoidal type.

Triangle (triangle): formed by triangular type.

Square: Shaped by a square type.

(Randomize) randomization: Click Randomization, then the image to be processed will be randomly deformed.

(Undefined Areas) undefined zone:

Retrace (Wrap Around): The image is divided into several parts for display.

Repeat Edge pixel (Repeat edge Pixels): Copy on the basis of the original graphic.

(one) wave (wave)

The filter can produce a ripple effect based on parameters such as the set wavelength.

Number of generators generators: The larger the number, the more shadows will appear inside the image.

(wavelength) Wavelength:

Min: Enter a value in the minimum to control the end position of the largest stroke drag.

Max (max): The maximum output value can control the end position of the minimum stroke drag.

(amplitude) Amplitude:

Min: Enter a value in the minimum to control the end position of the maximum stroke drag.

Max (max): Enter a value in the maximum to control the end position of the minimum stroke drag.

(Scale) Ratio: Level (HORIZ): To the level of the variable Formation degree.

Vertical (Vert): with vertical to variable formation degree.

(type) Type: Sine (Sine): formed by sinusoidal type.

Triangle (triangle): formed by triangular type.

Square: Shaped by a square type.

(Undefined Areas) undefined zone:

Retrace (Wrap Around): The image is divided into several parts for display.

Repeat Edge pixel (Repeat edge Pixels): Copy on the basis of the original graphic.

(a) zigzag (water ripple)

The ripple generated by the filter in the image is like a ripple formed by throwing a stone into a pool, which is especially suitable for making concentric circles of ripples, which have been translated into "sawtooth wave" filters.

(Amount) Quantity: Adjusts the number of current image water ripples.

(ridges) Fluctuation: Adjusts the fluctuation of the current image water ripple.

(style) Profile: Around the center (Around Center): Water ripple effect around the center.

From the center outward (Prt from center): Water ripple effects from the centre outward.

Pool Ripple (Pond ripples): Imitation of the effect of the pool ripple.
