Inkscape gradient alpha bitmap1/21/2024 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. 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.
