Your computer will need enough RAM to handle this. Note: Tracing large upscaled bitmaps will result in an immense amount of data. We now can select all yellow objects, create a union object from these, and adjust fill and stroke (here a 10 px white stroke): disable all, Smooth, Suppress speckles, Smooth corners, and Optimize Path): Then I traced this image ( right) with 12 color scans and without any path optimization (i.e. The example below show a detail from above image linearly scaled by 1000% to reveal pixel blocks ( left). Select all the objects that you want to clip / crop, and group them together with Object > Group from the menu. Select the single yellow object to adjust Stroke or Fill settings to desired values (here I applied a 6 Pixel white stroke):įor a higher precision of the trace (down to pixel size) we may have to scale up our source bitmap, depending on its content. Reduce number of Scans until the desired object is clear (here I used 6)ĭelete all objects of unwanted colors until only a single color is left over (imported bitmap is removed here only to better demonstrate the effect):.In Mode tab choose Colors, and Smooth. You need to select an object that satisfies a certain criterion, which in this case is the color of the object.Select the bitmap and choose Path > Trace Bitmap.: You need to select an object that satisfies a certain criterion, which in this case is the color of the object. This is how I selected the color yellow of the sunflowers to add a white border to all sunflowers.įile > Import bitmap (embed) to the Inkscape canvas: You can also select many objects at once by dragging around them. Hold down Shift to select multiple objects at once. Clicking the object once shows handles for resizing it, and clicking it a second time switches to handles for rotating it. The way to generate objects by color in Inkscape would be to trace the bitmap to vector paths. Click an object with the Select tool to drag it around the canvas and to display handles for transforming it.
