Adjust Image Tool¶
The Adjust Image tool is designed to greatly simplify the process of tweaking image properties such as contrast, brightness, and gamma while also changing the engrave settings. Best of all it allows you to instantly see the results of these changes with both the image properties and engrave settings applied.
The Adjust Image tool can be accessed by selecting any single image, right clicking, and choosing the
Adjust Image option.
On the top left the original grayscale source image is displayed. On the top right is the processed result of the chosen settings. Just like in the main edit window, you can use the mouse scroll wheel to zoom in and out on the image and clicking and dragging to move the image around. The source image and output image are kept in sync while zooming and moving around.
The Layer Settings group on the left contains settings that correspond directly to those found in the Cut Settings Editor, as highlighted below:
When adjusting an image and changing these settings, it will update those values on the cut layer currently used by the image selected when you click the OK button. If you click Cancel, nothing will be changed. It should be noted that these settings will affect any image on the same layer.
The most important setting here is the "Image Mode" dropdown as it will allow you to choose from the various image processing modes we have. Unlike changing this setting from the Cut Settings Editor, you get to see what that image mode looks like immediately, side-by-side with the source image.
The Image Settings group on the right contains settings that correspond directly to those found in the Image Shape Properties panel. In the Adjust Image window, they're provided as easy to use sliders, so that you can very quickly tweak these values to get the desired result.
LightBurn offers two image presets within the Adjust Image window, as well as the option to save your own frequently used image settings as custom presets.
The Basic preset is a good starting point for your own engravings or custom presets. The Black Paint on White is similar, but inverted for engraving light marks onto dark surfaces.
Save Image Preset¶
The first button next to the Presets dropdown allows you to save your current settings as an image preset. You can choose which layer and image settings are included in the preset. Any settings not included won't be changed when the preset is loaded.
Delete Image Preset¶
The second button allows you to delete presets. Make sure the preset you want to delete is selected in the dropdown first.
Export/Import Image Preset¶
The third and fourth buttons allow you to export and import image presets, which is useful for backing up your presets and for moving them between computers.
