1. glow (color = color, strength = light size)

2. fliph () enables the object to flip 180 degrees horizontally.

3. Vertical flip flipv (): 180 degrees vertical flip of Objects

4. object fuzzy blur (add = true/false direction = direction strength = intensity)
Add: Specifies whether to perform fuzzy direction based on the impression style; fuzzy direction: strength; fuzzy intensity
5. transparent object alpha (opaction = 0-100, finishopacity = 0-100, style = 0/1/2/3)
Opaction object overall opacity value finishopacity when the object uses the progressive transparency, this specifies the end transparency position opacity value. style specifies the transparency mode. 0 indicates the overall transparency, 1 indicates the linear transparency, and 2 indicates the circular transparency, 3. rectangular transparency
6. Remove the color chroma (color = color value) to make the color area of the object transparent with the specified color
7. Create a shadow dropshadow (color = shadow color, offx = horizontal deviation from the pixel to the left, offy = horizontal deviation from the pixel)
8. Color-removing gray () enables gray-scale display of Objects
9. Negative Effect invert (): displays negative effects on objects.
10. Highlight light (): displays the object in black.
11. mask (color = color) so that the entire object is masked once in the specified color


Opacity table transparency level. 0 ~ 100, 0 tables are completely transparent, and tables are completely opaque
Gradient transparency to be set in the finishopacity table. 0 ~ 100.
Style table transparent area shape. 0 table uniform shape. 1 Table linear. 2 Table radiology. 3 Table rectangle.
The X and Y coordinates at the beginning of the gradient transparency effect in the startx. starty table.
Coordinates of x and y at the end of the finishx and finishy gradient transparency effect.
Add to determine whether to make the original target in the blur effect. The value is 0, 1.0 table "no", 1 Table "yes ".
Ction sets the direction of The Blur. 0 degrees the table is vertical up, 45 degrees is a unit. The default value is 270 degrees to the left. left, right, down, up.
Strength can only be determined by an integer. It indicates that the width of the number of pixels will be blurred. The default value is 5.
The color must be transparent.
Offx and offy are respectively the offsets of shadows in the x and y directions.
Positive refers to the projection method. 0 table transparent pixel shadow generation. 1 Table only gives opaque pixel shadow generation ..


AddAmbient: adds a surrounded light source.

Freq is the ripple frequency. It specifies the number of finished ripple to be generated in the area on the object.
Lightstrength can be used to enhance the effect of ripple-shaped light and shadow ~ 100 positive integer. the start position of the sine wave is 0 ~ Table 0 starts from 0 degrees and Table 25 starts from 90 degrees.
The amplitude of the strength table.
