Ways to use CSS filters

css| Filter

There are two ways to use the specific application:

1, first define a good CSS, and then in the page need to use the predefined CSS, in fact, the CSS Settings dialog box has been in advance the syntax of these filters have been set up, we just fill in the appropriate specific parameters can be:

2. Write CSS filter code directly on HTML control elements that support CSS filter effects.

A.alpha Filter

The Alpha attribute mixes a target element with the background. Designers can specify values to control the degree of mixing. This "mixed with the background" is popularly said to be the transparency of an element. By specifying coordinates, you can specify the transparency of different ranges.
Alpha filter Syntax {filter:alpha (opacity=opacity,finishopacity=finishopacity,
Style=style,startx=startx,
Starty=starty,finishx=finishx,finishy=finishy)}

Filter:filtername (Parameters) is filter: Filter name (parameters)

Filter effects	Function description
Alpha	Set different transparency change effects
Blur	Create a Blur effect
DropShadow	Creates an offset image contour, which casts a shadow
Fliph	Flip horizontally
Flipv	Flip vertically
Glow	Adds color light to the bounds of the object
Gray	Display a picture in grayscale
Invert	The color, saturation and brightness values are completely reversed, similar to the film effect
Light	Light projection on an object
Mask	Create a color transparent mask for an object
Shadow	Shadow effect of creating outlines for an object
Wave	Use sine wave to disrupt pictures in X and y axes
Xray	Show only the outline of an object

The parameter meanings are as follows:

Parameters	Description
Opacity	Transparency. The default range is from 0 to 100, and they are actually in the form of percentages. In other words, 0 represents total transparency, and 100 represents total opacity.
Finishopacity	is an optional parameter, and if you want to set the transparency effect of a gradient, you can use them to specify the transparency at the end. The range is also 0 to 100.
Style	To specify the shape characteristics of a transparent region: 0 represents a unified shape 1 representing linear 2 represents radial 3 Represents a rectangle
StartX	The x-coordinate at the beginning of the gradient transparency effect.
Starty	The y-coordinate at the beginning of the gradient transparency effect.
Finishx	The x-coordinate at the end of the gradient transparency effect.
Finishy	The y-coordinate at the end of the gradient transparency effect.

B. Blur FilterThe picture becomes blurred when you use your finger to quickly cross a picture that is not yet dry. "Blur" is to produce the same blur effect.

Blur filter syntax

Html:{filter:blur (Add=add,direction=direction, Strength=strength)} Script language: [oblurfilter=] Object.filters.blur

The parameter meanings are as follows:

Parameters	Description
Add	It specifies whether the picture has been changed to an impressionist blur effect. The blur effect is in the clockwise direction, This is a Boolean value: Ture (default) or False
Direction	This parameter is used to set the direction of the blur. 0 degrees represents vertical upward, each 45 degree is one unit, the default value is 270 degrees to the left
Strength	Only integers can be used to specify how many pixels the width will be affected by the blur, and the default is 5 pixels.

C. DropShadow Filter

"Dropshaow", as the name implies is to add object shadow effect. Its working principle is to create an offset, plus color.

DropShadow Filter Grammar

{Filter:dropshadow (color=color,offx=ofx,offy=offy,positive=positive)}

The parameter meaning is as follows:

Parameters	Description
Color	Represents the color of a projected shadow
Offx	The offset of the shadow in the x direction
Offy	The offset of the Y-direction shadow
Positive	Boolean value If True (non 0), create a visible projection for any non-transparent pixel If Fasle (0), create a transparent effect for the transparent pixel portion

D. Fliph, FLIPV filter

FLIPH filter to achieve horizontal inversion

fliph Filter syntax

{Filter:filph}

FLIPV filter to achieve vertical inversion

FLIPV Filter syntax

{FILTER:FILPV}

E. Fliph, FLIPV filter

FLIPH filter to achieve horizontal inversion

fliph Filter syntax

{Filter:filph}

FLIPV filter to achieve vertical inversion

FLIPV Filter syntax

{FILTER:FILPV}

F. Glow Filter

When you use the "glow" attribute on an object, the edge of the object produces a glow-like effect.

Glow Filter Grammar

{Filter:glow (Color=color,strength)}

The parameter meaning is as follows:

Parameters	Description
Color	Specify the color of the glow
Strength	Strength, any integer value from 1 to 255, specifying the intensity and range of the glow color.

G. Gray, Invert,xray filter

Using the gray filter to turn a picture into a grayscale image, the syntax is simple:

Gray Filter Grammar

{Filter:gray}

H. Gray, Invert,xray filter

Using the gray filter to turn a picture into a grayscale image, the syntax is simple:

Gray Filter Grammar

{Filter:gray}

I. Mask Filter

Mask Filter Grammar

{Filter:mask (Color=color)}

Use the "MASK" property to create an object covering the surface of the film, the effect is like wearing tinted glasses to look at objects.
J.

Light Filter

Light Filter Grammar

{Filter:light}

This property simulates the projection effect of the light source. Once you have defined the LIGHT Filter property for an object, you can call its method to set or change the property. The available methods for "LIGHT" are:

Parameters	Description
Addambient	Join the surround Light
Addcone	Add Cone Light
Addpoint	Add Point Light
Changcolor	Change the color of light
Changstrength	Change the intensity of the light source
Clear	Clear all the lights
Movelight	Moving Light

K.Shadow Filter

Shadow Filter Grammar

{Filter:shadow (color=color,direction=direction)}

Use the "Shadow" property to create a projection of the object in the specified direction, color is the projection color, and the direction is the direction to set the projection. 0 degrees represent vertical upward, and then each 45 degree is a unit. Its default value is 270 degrees to the left.
L.

Wave Filter

Wave Filter Grammar

{Filter:wave (Add=add,freq=freq, Lightstrength=strength, Phase=phase,strength=strength)}

Parameters	Description
Wave	The object is disturbed by the vertical waveform style. The default is TRUE (non 0)
ADD	Do you want to disrupt the object in a waveform style?
Freq	The frequency of the ripple, which specifies how many complete ripples are required to be generated on the object altogether.
Lightstrength	can enhance the effect of the ripple, the range 0----100
PHASE	Set the offset of the sine wave
Strength	Amplitude size

M.Gray, Invert,xray filter

Using the gray filter to turn a picture into a grayscale image, the syntax is simple:
