This is an object oriented interface to the original
|
||||
ImageCFC.
|
||||
|
||||
Example Code:
|
||||
|
||||
io = createObject("component","ImageObject");
|
||||
io.setOption("defaultJpegCompression",95);
|
||||
io.init("#ExpandPath(".")#/emily.jpg");
|
||||
io.scaleWidth(500);
|
||||
io.save("#ExpandPath(".")#/imagex1.jpg");
|
||||
|
||||
io.flipHorizontal();
|
||||
io.save("#ExpandPath(".")#/imagex2.jpg");
|
||||
io.revert();
|
||||
io.filterFastBlur(2,5);
|
||||
io.save("#ExpandPath(".")#/imagex3.jpg");
|
||||
io.revert();
|
||||
io.filterPosterize(32);
|
||||
io.save("#ExpandPath(".")#/imagex4.jpg");
