Image & Signal

The IMAGE & SIGNAL setting defines the range of gray shades—from pure black to pure white—that Vexy Lines considers when processing your image.

Imagine a scale from 0 to 255, where 0 is pure black and 255 is pure white. Every number in between represents a different shade of gray. The diagram shows taller columns for the gray values that appear most often in your image—darker on the left and lighter on the right.

invert-mode Invert: switches the threshold or signal to inverted mode.

threshold-image-mode Image: displays the source image.

When using fills with varying line thickness, the darkest parts of your image produce the thickest lines, while the lightest parts produce the thinnest. By adjusting the white color threshold, you can control the precise balance of line thickness in different areas.

threshold: 0 - 255 threshold: 0 - 170 threshold: 0 - 60

You can set the range of acceptable gray shades using the sliders or by entering values manually into the input fields.

Or you can double-click the indicator to set the optimal threshold value.

In this example, any part of the source image with a gray value below the minimum or above the maximum is ignored.

image threshold: 0 - 255 threshold: 0 - 150 threshold: 75 - 150

The fill trace outlines only those parts of the image that fall within the gray value range you've specified.

image threshold: 0 - 180 threshold: 0 - 125 threshold: 100 - 125

Inverted Mode

To simplify working with white fills, you can invert the threshold diagram. In inverted mode invert-mode, the highest gray value (255) appears as black, and the lowest (0) appears as white.
