2) filter attribute Parameters

A)Set transparency alpha　　

Syntax: {filter: alpha (opacity = N1, finishopacity = n2, style = #, startx = x1, starty = Y1, finishx = x2, finishy = Y2 )}
"Opacity" transparency. from 0 to 100, 0 indicates completely transparent. Indicates completely opaque.
"Finishopacity" (optional) specifies the transparency between. 0 and 100 at the end.
"Style" Transparent area shape. Where # Can Be: 0 represents a unified shape, 1 linear, 2 radial, 3 rectangular.
Start X and Y coordinates of the gradient transparency effect "startx" and "starty.
"Finsihx" and "finsihy" gradient transparency ends the coordinates of X and Y.
<! -- [If! Supportlinebreaknewline] -->
<! -- [Endif] -->

B)FuzzyBlur

Syntax: {filter: blur (add = add, direction = direction, strength = strength )}
"Add" "true (default)" or "false". specifies whether the image is changed to the fuzzy effect of the image. 1 is true, 0 is false
"Direction" sets the blur Direction. 0 vertical up, every 45 degrees is a unit. The default value is 270 degrees to the left.
The width of "strength" pixels is blurred. The default value is 5 pixels.

 

C)TransparentChroma

Set the specified color to transparent
Syntax: {filter: chroma (color = color )}

Color, set to the value of the transparent color

Example:

D)Projection shadow

Syntax: {filter: dropshadow (color = color, offx = x, offy = Y, positive = positive )}
"Color" shadow color
"Offx" and "offy" are the offsets of shadows in the X and Y directions.
"Positive" if "true" is used to create a visible projection for any non-transparent pixel. If it is "false", a visible projection is created for the transparent pixel part.

E)Flip fliph and flipv　　

Syntax: {filter: fliph}, {filter: flipv}

Reverse the object horizontally and vertically.

F)The light effect glow is added to the outer boundary of the object.　

Syntax: {filter: glow (color = color, strength = n )}

"Color" Luminous color
"Strength" intensity from 1 to 255

G)Image Color Conversion

Gray-scale invert reversed Xray reflects the image contour and brightens these contours (X-ray effect, gray-scale reversed)
Syntax: {filter: Gray} {filter: Invert} {filter: Xray}

H)Shadow　　

Syntax: {filter: Shadow (color = color, direction = direction )}
Color Projection Color
Direction projection. 0 degrees vertical up, then every 45 degrees is a unit. The default value is 270 degrees to the left.

I)Sine Wave　　

Use sine ripple on the X and Y axes to disrupt the image

Syntax: {filter: Wave (add = true/false, freq = N, lightstrength = N1, phase = n2, strength = N3 )}
"Add" indicates whether to disturb. The default value is "true ".
How many complete ripple does "freq" generate.
"Lightstrength" enhances light and shade, an integer between 0 and.
The offset of the "phase" sine wave. The value ranges from 0.
"Strength" indicates the amplitude.
