Pass color information from SVG to driver #137

Open kkaempf opened 4 years ago

Motivation

Some Lasercutters, like those using the Ruida controllers, have the ability to preview the laser path in a small color display.

Since VisiCut maps SVG colors to laser settings, it would be helpful to visualize the same colors in this display. Drivers like ThunderLaser currently use random colors to visually differentiate layers and their power settings.

Goal

Pass the rgb color information from the input .svg file to the LaserProperty object attached to the set of VectorCommands representing the respective svg path elements.

Drivers can then use this to enrich the laser cutter commands and display a color-correct preview in displays.

Well I am not sure if this is the right approach. Visicut can map any svg property (color,layer,thickness etc) to a Laser-Profile like cut,mark cut deep or whatever you like. And the preview shows the color of the laser profile. Eg I use to draw cut in red end mark (=cut but not cut through) in black. But I can have a mapping which maps blue and green paths to cut and everything else to mark, so I would rather use the color of the Laser-Profile. The it would match the preview in visicut and it would also work if I have a layer for cut and another layer for mark.

it would match the preview in visicut

However, the profiles in VisiCut don't have a preview color. There are three colors per material: engrave, cut and background. Line profiles can be switched between the cutting color ("cut through") and the engrave color ("engrave line").

@mgmax you are right... I should use my own program more often....
