A Vector image is a style of image that instead of having pixels, has something called paths. What this does best is allow you to make an image as big or small as you’d like without distorting the picture or losing clarity. It can do this because Vector images are numerically based Paths. Photoshop supports the use of Vector images and you can actually convert regular photo that uses pixels into a Vector image.
Converting an Image to Vector
1. Open the image that you are wanting to convert to vector and draw a path around each object. You can try the Magic Wand tool by selecting it from the main toolbar. If it is a simple image the Magic Wand tool will correctly identify the edges of the object in the image. If it does, it will draw a path around it.
If the Magic Wand tool doesn’t work, you will need to select the Magnetic Lasso tool from the toolbar. Use this tool to trace the edges of the objects in the image and when you finish the path should snap to the edges of the image tightly to give you a perfect tracing
2. Now, click on the Make Work Path from Selection option. You will find this on the Paths work palette, and it looks like a circle with lines coming out of each side. When you click on this it turns the tracing you did before into a Path
3. After this, you will want to Export the Paths you have made by clicking on File and then clicking on the Export option. Then choose the Paths option when it pops up and a window should pop up with Exporting options
4. Here, you want to save the image under a new name so that you can tell the difference. You can type the new name in the File Name text box in the Export window. Now, click Save. This will save the file as an Adobe Illustrator Vector file(.ai).
5. After saving the file you may have to make some corrections to the image. The Path may look jagged, or not so crisp along the edges. You can do this by opening the new .ai file in Photoshop and using Photoshop tools to smooth out the edges of the image. You can select individual Paths by using the Path Selection Tool. w\after selecting the Path, you can smooth the edges, or you can use the Eraser tool to smooth the Path lines.
How to Convert a Bitmap to a Vector
1. First, you need to open the bitmap file and use the Magic Wand or Magnetic Lasso tool to trace the object that you want to convert. The Magic Wand tool may trace the image just by clicking it if the image is simple enough, but if not, the Magnetic Lasso tool can be used to trace and enclose the object in a Path
2. Now, you need to click on the Paths panel and select the Make Work Path from Selection option to make a copy of the path around the object in the image. You can find this selection at the bottom of the panel and it looks like a circle with lines coming out of it
3. Next, click File and then click Export. Now, choose the Paths to Illustrator option to save the path. This will bring up the Export Paths pop up window
4. Here, you name the file in Illustrator. Then, you need to clean up the path you made by adjusting the anchor points or by using the Smooth tool. If you used the Magic Wand tool you will definitely want to smooth the edges of your image.
