Vector
A vector is a curve (path) made up by dots, which can be scaled without losing definition.
Bitmap
A bitmap is a matrix made up by color dots (bits), which has color depth depending on the number of bits per pixel and is described by width and height in pixels.
When working with the CFM for bit maps, all files must be saved in 1 bit and .BMP format. Why 1 bit? The LaserCA software is binary, meaning that only understand color bits (white) or absence (black) of it and the CFM translates it as laser cuts (white) or laser stands by (black). What’s interesting about bit maps is that contrary to engraving that works with specific speed and power inside an area, bit maps allow you to make gradients depending on the amount of bits (white). Also bitmaps are a good option for accurate representation of an image or vector.
Engraving
Engraving employs a path and the engraving function that converts that path in a bitmap, meaning that it covers the area inside the path and then sent to the CFM it is translated as columns with color bits (white). Engraving covers the whole area in white, and applies the same speed and power through it.
Cutting
The CFM uses paths (vectors) that are given the right speed and power in order for the laser to go through the material. For the LaserCA software cutting also may be applied for tracing paths using different speed and power values, thus letting you mark the material without going through it.
