Resizing
Original 特殊服务 could be bigger or smaller than the 特殊服务 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 特殊服务s interpolating pixels.
- Nearest Neighbour: preserve hard edges scaling the 特殊服务 without smooth any pixel.
Grayscale and RGB sliders
If you open a coloured 特殊服务, 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 特殊服务s 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 特殊服务, as well as increase the contrast.
With BW option you can activate a threshold on the 特殊服务: pixels brighter of the threshold will be considered white, darken will become black.
All of these options affect how the various 特殊服务s process the 特殊服务 and produce the final result.
Since different materials behave differently when they are engraved with 特殊服务, it is essential to play with these options to find the best combination for the desired result.
