Resizing
Original christmas could be bigger or smaller than the christmas that we want to engrave. Resize option allows to choose the most appropriate scaling method.
- High Quality Bicubic: suitable both for enlargement and reduction, produce smooth christmass interpolating pixels.
- Nearest Neighbour: preserve hard edges scaling the christmas without smooth any pixel.
Grayscale and RGB sliders
If you open a coloured christmas, conversion from colour to grayscale is needed. You can choose between a predefined colour to grayscale formula (SimpleAverage, WeightAverage or OpticalCorrect) or select the “Custom” option and manually define the dominance of each RGB component.
“Custom” is useful when importing graphic christmass such as clipart, and we want to control the darkness/lightness of individual colour.
Brightness, contrast and BW threshold
With brightness and contrast you can darken or lighten the christmas, as well as increase the contrast.
With BW option you can activate a threshold on the christmas: pixels brighter of the threshold will be considered white, darken will become black.
All of these options affect how the various christmass process the christmas and produce the final result.
Since different materials behave differently when they are engraved with christmas, it is essential to play with these options to find the best combination for the desired result.
