Font Family

Warning If you use windows os you must add font family in your windows before use addFontFamily

// Add new Font Family 
form.addFontFamily(/* path: string, setName: string, options?: {style?: string, weight?: string} */) // You can add any name in setName

for examlpe:

form.addFontFamily("./Halimun.ttf","Halimun");
let text = form.createText();
text.draw({x:200, y:100, text:"Hello", fontFamily:"Halimun"});
text.draw({x:500, y:100, text:"Hello", fontFamily:"Impact"});

Canvas size

// change size canvas 
form.setCanvasSize(height, width) // default height = 1920, width = 1080

Other method

// save Image
form.toSave(path, type); // path = "save local device without .", type = "png" | "jpeg"

// convert to Buffer
form.toBuffer() // return Buffer

One example in detail

form.createRect(/*options*/).draw({x:500, y:100, color:"red"}).draw({x:700, y:100, color:"red"}).draw({x:900, y:100, color:"red"});

OR

form.createRect({y:100, color:"red"}).draw({x:500}).draw({x:700}).draw({x:900});

OR

let rect = form.createRect(/*options*/);
rect.draw({x:500, y:100, color:"red"});
rect.draw({x:700, y:100, color:"red"});
rect.draw({x:900, y:100, color:"red"});

OR

let rect = form.createRect({color:"red", y:100});
rect.draw({x:500});
rect.draw({x:700});
rect.draw({x:900});
