![]() The computer remembers the colors of all the squares in a row in a certain order, which explains why bitmaps require more memory to store information. A raster image, unlike a vector image, is capable of transmitting a realistic image with a lot of small details. For example, any digital photo consists of these multicolored dots. Looking at the screen with thousands of dots of different colors and shades, people identify objects and images composed from them (McAndrew, 2015). The more points on the plane and the smaller they are, the more one sees the image. To convert scanned images into vector objects, you need a special class of software called “raster to vector”.In bitmap images, each square called raster has its color and brightness, composing a mosaic. ![]() Note! Our software does not convert scanned images (raster PDF) into editable objects. It’s best to use the lowest resolution which achieves the level of quality you want. 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? Add PDF support to an application or automate a PDF conversion or creation process, check out our Developer Centerģ Ways to Tell The Difference Between Vector and Raster PDF Watch a Short Video to Learn the Difference.Convert a scanned drawing to an editable file, try the tracing tools in Adobe Illustrator or search on-line for “raster-to-vector” solutions.Convert PDF to image formats, try pdf2picture.Work with PDF-based graphics such as logos, drawings, diagrams and charts, look at pdf2picture.Transform a PDF page into an editable PowerPoint slide, try Insert PDF in PowerPoint.Open and edit vector PDF diagrams in Visio, check out Insert PDF for Visio or pdf2picture.Use PDF in a CAD/CAM program, look at pdf2cad, PDFin for AutoCAD, pdf2bricscad, PDF Import for DraftSight, PDFImport for ProgeCAD.If a raster PDF or scanned drawing is run through our software, we will turn the flat image into a tracing layer for manual work-up. Visual Integrity is specialized in tools for vector conversion and will produce high-quality, accurate drawings from vector PDF input. This is an approximation and requires operator involvement as well as manual clean-up. Raster PDF files are traced since there is no data to extract. This is accurate and precise and involves minimal manual clean-up. Vector PDF files are best transformed through data extraction. This is important since the two file types are converted differently. ![]() ![]() It’s easy to tell the difference between vector and raster PDF files by viewing them in Adobe Acrobat. Knowing Which Type of PDF File You Have is Key. ![]()
