Filter: alpha (opacity = 100, style = 1)

Filter: alpha (opacity = 100, style = 1)

1. Opacity attribute: sets the transparency. The value ranges from 0 to 100. The value 100 indicates that the image is completely opaque;

2. Style attribute: Set the gradient style;

0 indicates a uniform gradient,

1 indicates linear gradient,

2 indicates a radiation gradient,

3 indicates the right angle gradient.

Filter: alpha (opacity = opcity, finishopacity = finishopacity, style = style, startx = startx, starty = starty, finishx = finishx, finishy = finishy)

Opacity indicates the transparency level. The optional values range from 0 to 100. 0 indicates full transparency, and indicates full opacity. The style parameter specifies the shape features of the transparent area. 0 represents a uniform shape; 1 represents a linear shape; 2 represents a radial shape; 3 represents a rectangle.

Finishopacity is an option used to set the transparency at the end to achieve a gradient effect. Its value also ranges from 0 to 100.

Startx and starty represent the starting coordinates of the gradient transparency effect.

Finishx and finishy represent the final coordinate of the gradient transparency effect.
