12/1/2023 0 Comments Vector vs raster artwork example![]() Keep in mind that the higher the dpi (resolution), the larger the file size. If publishing to a web-site, use 96 or 72 dpi is best for screen display. If you will be printing the graphic on a laser or ink-jet printer, convert at 150 or 300 dpi (dots per inch) resolution. The image formats that we support are TIFF, GIF, PNG, JPEG and BMP. If you do not need to edit the file and simply want a sharp copy to insert into a document or to publish on a web-site, you can go with image formats. The vector formats supported in our software are DXF, PDF, PS, EPS, SVG, WMF, EMF, CGM, HPGL and MIF. If you need to break a PDF file down into objects and text for editing, then you want to choose a vector format. ![]() It’s important to know which is best for the job you are doing. Visual Integrity can convert most PDF files into either vector or image formats. Images are also referred to as bitmaps or rasters. Vector graphics are made up of objects, lines, curves and text while images are made up of a collection of dots or pixels. Once you understand the two basic formats for graphics – vector and image, you know the tools to pick. Which Graphics Formats Should I Pick For Web and Print? In this example, it’s possible to edit the vector PDF on the left but not the raster PDF on the right. Sometimes, it’s necessary to magnify the file more than 1000% if it’s a high-resolution scan to determine the file type. In the example below, the drawing is enlarged 400%. Visually evaluate the difference between vector and raster PDF. Side-by-Side Comparison of Vector and Raster PDF The vector PDF file will look clear and smooth at any size while the raster PDF will become blurry or grainier the more it’s zoomed. The section of the picture should be magnified on your screen and it quickly becomes apparent whether you have a vector or raster PDF file. Vector files will look perfect at any resolution. The higher the resolution of the drawing, the more magnification it needs to degrade. When magnified, a scanned drawing will look jagged, noisy, blurry or dirty. Continue zooming until you are at a magnification greater than 400%. At 100-150%, it may be hard to tell the difference. Use the Magnifying Control to zoom in on a detailed section of the file. Use Acrobat, Acrobat Reader or just your browser. The Zoom TestĪnother way to tell the difference between vector and raster PDF is to open the file. Once you click anywhere on the scanned drawing, the entire drawing is selected and turns blue to signify this. A scanned drawing as it opens on-screen in Acrobat (It has not yet been selected). Alternatives are to manually redraw it or outsource it to be redrawn by a service bureau. Depending on the quality of the scan, you may have some success with a raster-to-vector tool. If it turns blue, it’s a scanned drawing. Start by opening your PDF file with Acrobat or Acrobat Reader.
