Turn Bitmap into Vector with XCS Image Trace Function

Updated Dec 31,2024

You can convert a bitmap image into a vector by using the Trace function on the top toolbar.

Start Image Tracing

Click on the 'Trace' button to step into the trace editing interface. You'll notice a light blue vector line on your preview screen, while your source image appears faded.

Auto-trace

Auto-trace generates vector outlines along the edges of color blocks within a bitmap. Applicable to multi-color bitmaps with large color blocks.

Fuzziness Threshold

Fuzziness threshold plays a pivotal role in adjusting the image's vector measurement. The default value is 100, but you can modify it anywhere between 0-255.

A larger value delivers a coarser color-distinguishing granularity, thus producing fewer vector lines. On the contrary, a smaller parameter results in a finer color-distinguishing granularity, leading to more intricate lines.

Refer to the image examples below to see the difference:

Left: Threshold 255, Right: Threshold 0

Denoising

With the denoising parameter, you can ignore any color block with less pixel value than your set number, preventing it from generating a vector path. The default setting stands at 50, with a total range from 0-100.

For a clearer comparison, see the following examples:

Left: Denoising 0, Right: Denoising 100

Smoothness

The vector path is formed by incorporating lines together. However, since the bitmap's pixels are rectangular, it might form sharp angles at the vector path's inflection point. You can smooth out this angle by tweaking the smoothness parameter, resulting in a smoother, continuous vector line. The default setting stands at 0.8, with a total range from 0-1.

See the difference here:

Left: Smoothness 0, Right: Smoothness 255

Center tracing

Center tracing generates vector outlines along the centerline of color blocks within a bitmap. Applicable to single-color bitmaps and line drawings.

Best Practice

For bitmaps with rich colors and complex image elements, we suggest using the invert function. After inverting, you can trace more distinct vector lines for the image.

FAQs

What are Images that are NOT Suitable for Tracing?

Those with blurred outlines or colors that are similar to the background.
If an image has dense and vibrant colors, the software may struggle to generate accurate vector lines, causing failed vector generation.
