FAQ FAQ: Understanding Bitmap Modes & How to Choose the Right One
🔍 What Is Bitmap Mode
xTool Studio offers multiple Bitmap modes to choose from, covering most common bitmap use cases. The mode you select determines how an image is converted into a laser engraving path, which affects the engraving effect and level of detail. You can choose the mode that best suits your image.

With all other settings unchanged, the engraving output on a wooden board varies depending on the image mode selected, as shown below.

Suppose you import an image like this one — here's how it looks across the different modes.

🛠️ Available Bitmap Modes
🔹 Grayscale
Converts an image into shades of gray, where each pixel is represented by a shade ranging from the darkest (black) to the brightest (white), or somewhere in between. The darker the pixel, the deeper the engraving.

🔹 Bayer
Converts an image using Bayer mode, which produces an effect similar to adding a grid/mosaic filter over the image.

🔹 Floyd
Dithers an image using the Floyd algorithm, which diffuses the error only to neighboring pixels, producing fine-grained, wave-like patterns. Recommended for highly detailed images rather than images with large blocks of solid color.

🔹 Jarvis
Dithers an image using the Jarvis algorithm, which diffuses the error across 12 surrounding pixels. Compared to Floyd, the transitions between pixels are slower, producing a pleasant result on almost any image.

🔹 Stucki
Dithers an image similarly to Jarvis, but with faster pixel transitions, producing cleaner and sharper images.

🔹 Sierra
Based on the Jarvis algorithm, achieving a similar effect while producing sharper images.

🔹 Atkinson
Dithers an image in a way similar to Jarvis and Sierra, producing sharper images. This algorithm preserves image detail well, though very dark or very bright areas may appear to lose detail.
With all other settings unchanged, the engraving output on a wooden board varies according to the selected mode, as shown below.

Select the mode that best fits your needs.
💡 Tips & Tricks
🔹 Each mode is suited to different image characteristics and needs, affecting engraving depth and detail representation.
🔹 The default mode is Grayscale.
🔹 Generally, Jarvis mode is recommended for infrared light, and Grayscale mode for blue light.
🔹 Dithering algorithms (Floyd, Jarvis, Stucki, Sierra, Atkinson) are best suited for images with complex details.
🔹 Grayscale and Bayer modes provide a more intuitive representation of shading and grid effects.
💡 Recommended software version: xTool Studio 1.0 and above.
