The compression will ruin all of your hard work. Now, save the image as your master image NOTE that you do not want to save this as a JPG image. After that, my image is basically 3 colors black, white, and red (there are a few shades of grey and reddish-grey at the transitions between the 3 colors, but that is OK). Everything was converted to the single red color at this time. Because of the tolerance setting I used, I only had to move the tool over the red blended area once. I proceeded to move the tool around the image, with the button on the mouse held down to keep the tool active. Finally, I ensured that antialiasing was turned off. I then increased the brush size, so that the tool covered more of the image at once, and I also increased the tolerance, so that more shades of red were recolored. I chose RED as the foreground color, and then used the "eye dropper tool" (called "color picker" in Paint.NET) to select one of the blend colors in the red slash across the ghost. I use the free image editor Paint.NET for Windows, where the tool is called "Recolor." What the tool does is replace any color found that matches the background color with the chosen foreground color. To reduce the color count in your image, use the "color replacer tool" in your favorite graphics program. It turns out that the Ghostbusters image I found has over 10 colors in it (if you zoom in on the red, you will see a blend of many shades of red). In the first photo, you can see that the tiger should only be 4 colors, and the Ghostbusters logo should only be 3 colors. Ideally, the image should only have the minimal colors necessary to represent it. To convert it to a vector, we need to manipulate/touch it up. I'll describe how to deal with JPG images in the next step.Īt this step, you should have selected an image. If you can find images in PNG, TIFF/TIF, BMP, etc., you will likely be much better off (see the 3rd photo to see how a "line" isn't a clean line in a JPG). However, for what we are trying to achieve, this can be our largest source of problems. This is fine for photo-realistic images, because the subject is usually a real world photo where soft edges and transitions are preferred. It also blurs (aliases) the lines and loses detail. Trick 3: Avoid the Ubiquitous JPEG Image, if PossibleĪlthough the JPEG/JPG format is everywhere, it highly compresses images to save space. The "Line drawing" or "Clip art" types are right up our alley, as they won't be photo-realistic (see the second photo). To avoid having to wade through those types of results, you can use the Search tools again to select the Type of image you want. Trick 2: Check the Clip Art or Line Drawing FilterĪgain, photo-realistic images are not a good candidate for vector conversions. To ensure your Google Image search returns only suitably sized images, use the search tools that are at the top of the results specifically, Search tools -> Size -> Larger than. Once the image is converted to Vectors, you can scale it infinitely large or small, without losing detail but you have to get a high quality Vector image first. The higher the resolution of your starting image, the better success you are going to have with this process. I use a few tricks to find suitable images using Google. Just be sure that if you use the image for commercial purposes that you have rights to that image. If you don't already have an image to convert, the internet is a great resource. It will not work if you are trying to convert a photograph with many colors and gradient shading. This instructable is geared towards converting simple designs with distinct edges.
