There are a few things you need to know before starting vectorizing an image in Photoshop CC. First, the image must be in RGB color space. Second, the resolution of the image must be at least 2048x2048 pixels. Third, the file size of the vectorized image must not exceed 2GB. Finally, you will need to create a vector file using Adobe Illustrator or Inkscape. To begin vectorizing an image, select it from the File menu and then click on Vectorize. The Vectorize dialog will appear. In this dialog, you can choose how many points per inch to use for your vectors and how much space to give each point. You can also choose whether or not to have a fill color for your vectors. Finally, you can decide whether or not to have a background color for your vectors. If you do not want a background color, click on None at the bottom of the Vectorize dialog and then click on OK to close it. Now that your image has beenvectorized, you will need to save it as a .svg file so that you can use it in another program such as Adobe Illustrator or Inkscape.
