transformPointA (hopefully) quicker function to transform a point by a matrix (this function avoids any DOM calls and just does the math)
isIdentityHelper function to check if the matrix performs no actual transform (i.e.
matrixMultiplyThis function tries to return a SVGMatrix that is the multiplication m1*m2.
transformListToTransformThis returns a single matrix Transform for a given Transform List (this is the equivalent of SVGTransformList.consolidate() but unlike that method, this one does not modify the actual SVGTransformList) This function is very liberal with its min,max arguments

Sorry, but your browser does not support SVG. Below is a list of alternate browsers and versions that support SVG and SVG-edit (from caniuse.com).

-

Try the latest version of Firefox, Google Chrome, Safari, Opera or Internet Explorer.

-

If you are unable to install one of these and must use an old version of Internet Explorer, you can install the Google Chrome Frame plugin.

It can be a - function or an array of strings. - - space an optional parameter that specifies the indentation - of nested structures. If it is omitted, the text will - be packed without extra whitespace. If it is a number, - it will specify the number of spaces to indent at each - level. If it is a string (such as '\t' or ' '), - it contains the characters used to indent at each level. - - This method produces a JSON text from a JavaScript value. - - When an object value is found, if the object contains a toJSON - method, its toJSON method will be called and the result will be - stringified. A toJSON method does not serialize: it returns the - value represented by the name/value pair that should be serialized, - or undefined if nothing should be serialized. The toJSON method - will be passed the key associated with the value, and this will be - bound to the value - - For example, this would serialize Dates as ISO strings. - - Date.prototype.toJSON = function (key) { - function f(n) { - // Format integers to have at least two digits. - return n < 10 ?

It will be passed the - key and value of each member, with this bound to the containing - object. The value that is returned from your method will be - serialized. If your method returns undefined, then the member will - be excluded from the serialization. - - If the replacer parameter is an array of strings, then it will be - used to select the members to be serialized. It filters the results - such that only members with keys listed in the replacer array are - stringified. - - Values that do not have JSON representations, such as undefined or - functions, will not be serialized. Such values in objects will be - dropped; in arrays they will be replaced with null. You can use - a replacer function to replace those with JSON values. - JSON.stringify(undefined) returns undefined. - - The optional space parameter produces a stringification of the - value that is filled with line breaks and indentation to make it - easier to read. - - If the space parameter is a non-empty string, then that string will - be used for indentation. If the space parameter is a number, then - the indentation will be that many spaces. - - Example: - - text = JSON.stringify(['e', {pluribus: 'unum'}]); - // text is '["e",{"pluribus":"unum"}]' - - - text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); - // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' - - text = JSON.stringify([new Date()], function (key, value) { - return this[key] instanceof Date ? - 'Date(' + this[key] + ')' : value; - }); - // text is '["Date(---current time---)"]' - - - JSON.parse(text, reviver) - This method parses a JSON text to produce an object or array. - It can throw a SyntaxError exception. - - The optional reviver parameter is a function that can filter and - transform the results. It receives each of the keys and values, - and its return value is used instead of the original value. - If it returns what it received, then the structure is not modified. - If it returns undefined then the member is deleted. - - Example: - - // Parse the text.
