The original registration extension I made, puts all scans into their own layer the order, of which corresponds with the original z-order of the scans.Īs long as you don't drag or move things out of the layers that should remain forever. Nelchai - it depends what you mean by z-order. I know that after export the image I can use Gimp to move grays to transparent, but I prefer to do all the things inside Inkscape because from time to time I need to retouch some vector and make the procedure again and I can forget the external step on Gimp (Still a little older and forgot too many things). I've tried with Filter editor, Color Matrix, Luminance to Alpha but I'm a little older to understand the complexity of the filter editor, also I try almost all the filters and extensions and found nothing that made what I need. Is there any filter that I can apply to the vector image to convert all the gray colors to black with transparency? Is there any way to make the Trace bitmap tool to generate a black color with a transparency for each of the gray level? Now I need to work with a very complex image with many gray levels, so I need to make a 127 or more scans until I have a decent image based on vectors but I don't want to change manually every one of the 127 gray levels to a transparent color. (Some options tend to produce a lot more nodes than others.I've been using Inkscape from many years converting pixel images to vectors using the Trace Bitmap tool, then edit and work on vectors to finally generate a png output, most of the times I use monochrome images and I convert using 8 or 16 scans.īecause Trace bitmap tool generate grayscale image with solid gray colors I use to select each one of the colors and manually convert to black and set the transparency according a scale implemented in the moment, so, the pure black stay on black with 0 transparency, then some #101010 gray go to black with #10 of transparency, some #202020 go to black with #20 of transparency and so on. You may be able to adjust the Trace Bitmap (or RO IT trace) to result in as few nodes as possible, but we would need to see the image, to give specific suggestions. But if you do it a second time, it will distort the path much more. You can usually use Path menu > Simplify once, without much distortion. It would make a long, wordy explanation, but you can give it a try. This is one that does: However, note that the centerline trace can't accurately reproduce things like text. But there are other trace engines which do have a centerline trace option. Inkscape's Trace Bitmap cannot guess where the center of that line is, to create an identical single open path. The Trace Bitmap software can't make that determination. It draws a path around what it sees, even if what it's looking at, to humans, looks like a line. Now it's a closed path with probably 4 or 5 nodes. Even though the stroke is wide, it's still one single path segment, because there are 2 nodes, 1 at either end. Switch to the Node tool, and make the stroke fairly wide, like 20 or 30 px wide (to make it easier to see the result). Draw a simple straight line segment using Inkscape's Pen or Pencil tool. It will be a closed path.ĭo this experiment. When an image of a solid black line is traced, the result will not be a single path open path, as the line appears to be. So it doesn'st sound like you need to use Object to Path at all, for this project. And after you trace the image with Trace Bitmap, you have true paths. There's no need to do Object to Path on a raster image.
