To convert To convert A JPEG To A Vector File
Pictures have a way of conveying emotion without using words. But in the digital world, pictures are made up of tiny rectangular boxes called pixels. Whether the sun hitting the mountain highlights the great thing about the snow capped on the mountain, relies on clip in or sew in extensions the quality of those rectangular boxes. A voxel is the first unit of a 3D image, as it combines volume and pixels, giving it a 3D look.
Images are used for a variety of reasons, be it for enhancing a webpage or highlighting a cause. The primary reason it exists is to be noticed. If that does not happen, the idea is a failure. Images are split into two categories, namely, vector and raster. While some blur the content while reducing the size, others compromise on quality. Here, we shall tell you how to convert a JPEG right into a vector file, while keeping the integrity of the file intact.
What’s a Raster Image
A raster image is usually a photo created or captured in a set of dimensional space, usually ‘x’ or ‘y’ coordinates. If it’s a 3D image, the ‘z’ coordinate is used. It’s known as ‘bitmap’, because it’s directly mapped onto the grid. Examples of raster file types are BMP, GIF, and JPEG.
A raster image loses its quality when it’s zoomed into. This is due to a feature called DPI, or dots-per-inches. DPI refers to the variety of square pixels occupied in a square inch. In case of DPI, it determines the standard and resolution of the image. Raster images are used on web pages because they are compatible with all browsers. These are saved in a resolution of 72 DPI, but would lose their quality if scaled up.
What is a Vector Image
A vector image consists of lines and shapes encoded with the assistance of a mathematical formula. It allows you to scale up the image to any shape that you would like, without the loss of quality or resolution. A bitmap appears jagged when scaled, and a vector image retains its crispiness during the same. The most popular types are EPS, AI, and PDF. SVG (Scalable Vector Graphics) is a universal format created by the Worldwide Web Consortium, to offer a vector format for the online.
Logos of companies are created in a raster format, but saved in a vector form for the ultimate edit. Regardless of how much it’s zoomed in, the edges retain their positions. The image will not be pixelated.
Converting in Illustrator
1. Open the JPEG image in Illustrator.
2. Click on the image to pick it. You understand it’s selected by the blue box surrounding the image.
3. Click on the small down-arrow button next to ‘Live Trace’. Select one of the presets in ‘Tracing Presets’ and ‘Options’ within clip in or sew in extensions the control panel of Illustrator to determine the quality and threshold. If you’re happy with your current image, you should use ‘Live Trace’ directly to change it right into a vector format.
4. The threshold value tells you where we want to trace the lines. All pixels lighter than the threshold value is turned to white, and pixels darker than the threshold value are turned to black. The threshold value could be any number between 1 to 255.
5. Click on the ‘Trace’ button to trace the image.
6. Click the ‘Expand’ button to complete tracing the image.
7. Click on the ‘Color Palette’ to open the Color Palette window. Shapes in Illustrator have a ‘fill’ and a ‘stroke’. A fill is the color contained in the shape and ‘stroke’ is the outline color, given outside the shape. On the palette box, select the white box with a red slash running through it. The shape may have a clear fill or no color.
8. Change your ‘stroke’ color to black, thus filling the outline color.
9. Save or export the file in a vector format, to avoid wasting your work.
Converting in Photoshop
Upload or scan the image you want to convert into a vector image. The dimensions ought to be a minimum of 600 by 600, so it’ll be easier to zoom into.
1. Open the image. Double-click on the background layer to unlock it.
2. Select the background layer and duplicate it twice by utilizing Ctrl+D . Select the highest copy of the duplicated layer, and click on on the visibility tab or eye icon to turn off its visibility.
3. Click on the middle copy of the image and go to the ‘image’ tab, go to adjustments and select ‘desaturate’.
4. Select the copy again and go to the image tab, go to adjustments and choose ‘posterize’. Adjust the posterization level to 9 or whichever is acceptable. Rename the layer ‘Posterized One’.
5. Select the background copy and make it visible by clicking on the eye icon.
6. Click on the ‘layers’ tab, create a brand new layer, and drag it behind the background layer.
7. Use the ‘eye dropper’ tool to pick out a color of the actual element in the photo, and use the ‘pen tool’ to trace across the color.
8. Add a brand new layer for each element and color of the picture. Trace it with the ‘pen tool’, and add a color with the ‘fill tool’, selected using the ‘eyedropper tool’.
9. Change the opacity of each layer by dragging the opacity toolbar located near the ‘layer’ tab.
10. Zoom in and out to add appropriate shadows for each layer in a separate layer.
11. Save the ultimate image in a .eps format to keep the vector formatting intact.
These are the most effective methods to transform a JPEG into a vector file. You need to use Autotracer to trace your images online for a quick fix. You can even use Inkscape, an open-source software to trace your images directly. Whatever the strategy, vector images are scalable and can be used for a wide range of reasons.
