When working with laser cutter software such as RDWorks, you may see different layer types in your project. A layer marked with “BMP” is a bitmap image layer, while another layer may be a vector layer. Understanding the difference between BMP and vector files helps you choose the right processing mode for engraving, cutting, and design preparation.

In general, BMP files are commonly used for photo engraving and detailed image engraving, while vector files can be used for both engraving and cutting jobs. This guide explains the difference between BMP and vector graphics and how each type is used in laser processing.

1. BMP and Vector Layers in RDWorks

In RDWorks, a BMP layer and a vector layer offer different processing options. When you double-click a BMP layer, the processing mode usually has only one option: scan mode. This is because BMP images are mainly processed as pixel-based engraving data.

When you click a vector layer, you can usually choose from three processing modes: scan, cut, and dot. This gives vector files more flexibility for laser processing, especially when you need to cut outlines or follow precise paths.

1.1 When to Use BMP Layers

BMP layers are usually used for engraving photos, artwork, patterns, and images with detailed shading. The laser software reads the pixel information and processes the image line by line to create the engraved result.

1.2 When to Use Vector Layers

Vector layers are suitable for cutting, engraving, and dot processing. Because vector graphics are built from paths, lines, and geometric elements, they are ideal for designs that require clean outlines, accurate shapes, text, logos, and cutting paths.

2. What Is a BMP Image?

A BMP image is made of a grid of pixels. This makes BMP files suitable for displaying photographs, patterns, gradients, and detailed images. In laser processing, BMP images are mainly used for engraving rather than cutting.

During laser engraving, the machine uses the pixel color or grayscale values to control how the laser beam processes the material. This allows the laser to engrave point by point and line by line, creating detailed images, photos, and artwork on the material surface.

3. What Is a Vector Graphic?

Vector graphics are created from mathematical paths, lines, curves, and geometric shapes. Because they describe shapes with paths rather than pixels, they can accurately represent outlines, text, logos, and cutting contours.

In laser processing, vector files are mainly used for cutting and engraving. They are especially useful for cutting materials such as wood, leather, and fabric, and they can also be used to engrave text, logos, and decorative patterns by controlling the laser beam path and power.

3.2 Common Vector File Formats

Common vector graphics formats include AI, EPS, and SVG from Illustrator; DWG and DXF from AutoCAD; and CDR and PLT from CorelDRAW. These formats are widely used for laser cutting and engraving workflows.

5. Final Thoughts

BMP and vector files serve different purposes in laser software. BMP files are best for pixel-based image engraving, especially photos and detailed grayscale artwork. Vector files are better for precise cutting paths, outlines, text, logos, and scalable design work.

Choosing the correct file type helps improve workflow efficiency and output quality. Before starting a laser job, check whether the layer is BMP or vector and select the right processing mode for your project.
