1. Edge highlight glow (color=color, strength=glow size)

2. Flip horizontally fliph() to make the object horizontal Flip 180 degrees

3. Vertical flip flipv() flips the object 180 degrees vertically

4. Object blur blur(add=true/false direction=direction strength=strength)
add Specify whether to blur according to Impressionism direction blur direction strength blur strength
5. Object transparency alpha(opaction=0-100, finishopacity=0-100, style=0/1/2/3)
opaction object Overall opacity value finishopacity When the object uses gradual transparency, this item specifies the opacity value of the end transparent position style specifies the transparency mode 0 is overall transparency, 1 is linear transparency, 2 is circular transparency, 3 is rectangular transparency
6. Remove the color chroma (color=color value) to make the area in the object with the same color as the specified color transparent
7. Create a shadow dropshadow (color=shadow color, offx=deviate horizontally to the left by pixels, offy=deviate horizontally from pixels downward)
8. Decolorize gray() to make the object appear in grayscale
9. Negative effect invert() make the object appear in negative effect
10. Highlight light() to make the object appear in black
11. Cover mask(color=color) masks the entire object with the specified color once


opacity represents the transparency level. 0~100, 0 represents fully transparent, 100 represents completely opaque
finishopacity represents what you want The set gradient transparency effect. 0~100.
style represents the shape of the transparent area. 0 represents a unified shape. 1 represents a linear shape. 2 represents a radial shape. 3 represents a rectangle.
startx.starty represents the start of the gradient transparency effect. X and Y coordinates.
finishx, finishy coordinates of x, y when the gradient transparency effect ends.
add is used to determine whether the original target is used in the blur effect. The value is 0, 1.0 means "no" ,1 means "yes".
Direction sets the direction of the blur. 0 degrees means vertically upward, and 45 degrees is a unit. The default value is 270 degrees to the left. left, right, down, up.
strength can only Determine with an integer. It represents how many pixels of width will be affected by blur. The default is 5.
Color is the color to be transparent.
offx, offy are the offsets of the shadow in the x and y directions respectively.
Positive refers to the projection method. 0 means transparent pixels generate shadows. 1 means only opaque pixels generate shadows..


AddAmbient: Add a surrounding light source.
AddCone: Add a cone-shaped light source .
AddPoint adds a point light source
Changcolor: Change the color of the light.
Changstrength: Change the intensity of the light source.
Clear: Clear all light sources.
MoveLight: Move light source.


freq is the frequency of the ripple, specifying how many completed ripples need to be generated in the upper area of ​​the object.
lightstrength can enhance the effect of light and shadow on ripples. Significant positive integers from 0 to 100, the starting position of the sine wave is 0 to 360 degrees. 0 means starting from 0 degrees, 25 means starting from 90 degrees.
Strength indicates the amplitude.
