I also tried using magenta as being very unlike any color in map, but again got transparent areas. unable to find a successful off-white color) for a different map background with much more subdued colors, near-white in many places (USGS National Map, vice previous USGS Quad map) - going down to f0f0f0 (which was same as some areas of map itself) still gave transparent areas. Also, this result depended upon the "Smooth" checkbox - "f7f7f7" did not work when it was checked.įYI for others trying method two, I was unable to obtain a successful result (ie. the slightly whiter "fafafa" did not work, again giving transparent areas (for 32 colors - I assume this depends on number of colors requested). Finding the whitest successful value required some experimentation - i.e. Using "method two" from Billy Kerr succeeded after changing the "near-white" to "f7f7f7". Sorry for the tardy response, took awhile to work through this. PS: white area need to be white so logo can be placed a non-white background So cannot find a way to create a vector image from this logo containing "white" (or "near-white") and am hoping some more experienced user can provide a method of doing so. But to my surprise, the near-white area was again not traced, resulting in a transparent area. treat "white" as an actual color to be traced ala all the other colors - but could not find anything that worked.įinally I altered the PNG being imported to replace all its "white" #ffffff with near-white #fefefe, thinking that would not be considered "background". I tried many different variations hoping to stumble up something which which fix this behaviour, i.e. I used an editor to remove the graphic section, but found the resulting SVG then displays the original "white" areas as transparent, not white. (I had been expecting it to be removed with selection of "Remove background"). The white areas still appeared white - but when I saved as a SVG and examined with editor I saw that the graphic is still included. This is my first use of inkscape.įollowing other on-line procedures, after importing PNG I used 'Select All' and 'Trace Bitmap' with "Multiple scans: Colors: 32", "Stack scans", and "Remove background". Am trying to create a vector image since many places prefer such for inclusion with other logos, etc. PPPS - GIMP (and presumably Photoshop) have tools that will make turning a full color image into a pure black and white image easier, but their learning curves are steep.I have a PNG logo on a transparent background which has areas of pure white (#ffffff) and also pure black in addition to a wide assortment of other colors (logo includes a topo map). PPS - You’ll want to practice the Inkscape tutorials in the Tips and Tricks section. PS - Once Glowforge Support sees this thread they will move it somewhere else as they do not consider design questions part of their bailiwick. However you get there, once you have your outline import your same-sized png file, place it over the outline and now you can engrave the image and cut it out. That said, it can take some time to do this and maybe your image is good enough to just go straight to Path -> Trace Bitmap without any image manipulation. A bitmap with only two colors makes life a lot easier for the software and your results much better. Now import your black and white image into Inkscape and do a Path -> Trace Bitmap. For example, if you have an image of a trout, the trout would be solid black and everything around the trout would be white. Want you want is a more or less solid black image surrounded by white. Color every pixel outside the image white. Open the copy in Microsoft Paint (or GIMP or Photoshop) and color every pixel in the interior of the image black. If it doesn’t need to be resized then skip this step. If you do want an exact as possible outline of your image to be cut, and you’re not having much luck with the Path -> Trace Bitmap feature, my suggestion is import it into Inkscape, resize it and then do a File -> Export PNG image. If you go the trace route it will take some messing about with this feature possibly a lot of messing about. Inkscape can do some basic manipulation with a raster, like resize it by dragging one of its handles or by going to Object -> Transform and using that dialog to resize it.Īs for cutting out around it your two basic options are 1) make an object it will fit into using the create rectangles and squares, the create circles, ellipses and arcs or the create stars and polygons tool (which is what marmak3261 linked to) or 2) trace it and hope for the best using the Path -> Trace Bitmap feature. The glowforge can engrave a raster, several different ways, but all it can do to it is engrave it. A png is a raster, which just means it is a bitmap or a collection of pixels.
