Notice that three CMYK colors are listed at the top (as shown next). Click the Colors tab to examine the color results of the trace, and choose CMYK from the Color Mode list box. A close look at the upper-left corner (shown below) reveals that the bitmap edges have been accurately traced.Ħ.
If needed, use the Transparency slider to adjust the visibility of the original bitmap. Use single left-clicks to zoom in and single right-clicks to zoom out to examine the accuracy of the traced paths. To check the tracing accuracy, choose Wireframe Overlay from the Preview list box.
Notice that the Trace result details area now indicates that only 8 curves are detected.ĥ. To remove the white area in the interior of the bitmap, enable the Remove color from entire image check box (shown below). The preview window displays a split-screen preview of the Before and After results (as shown below), and the Trace result details area indicates that there are 14 curves comprised of 238 nodes and 3 colorsĤ. Since the background of our logo is white, PowerTRACE automatically detects and eliminates the surrounding background color. The Smoothing and Detail sliders at the top of the Settings tab are automatically set. The PowerTRACE dialog box opens and produces a preliminary trace of the bitmap.ģ. Click the Trace Bitmap button on the property bar, and choose Outline Trace > Logo. By default, the imported bitmap is selected with the Pick tool.Ģ. In a new CorelDRAW document, import the first bitmap (shown below). Our goal is to produce a usable vector version of the logo prepared in two PANTONE® spot ink colors. The first version was exported from a drawing program (CorelDRAW), while the second version was scanned by using a consumer-brand flatbed scanner. Both are CMYK images that have a resolution of 200 dpi and depict the same logo. In the steps that follow, we’ll look at both scenarios. Software-generated bitmaps are the best to work with, while scanned images often require some refinement before they can be accurately traced. The source of your bitmap image can significantly influence its inherent quality. The bitmap images that you are vectorizing will very likely come from one of two sources: a file that is prepared in a drawing or bitmap-editing application and exported to one of the many available bitmap formats, or a file acquired via an image-capturing device such as a scanner or digital camera. Before you convert bitmaps to vector images Follow the tutorial steps below to explore how easily these settings can be applied and modified to produce exactly the tracing results you need. The Colors tab includes controls that let you manipulate the color space of the traced results. The Trace result details area (shown below) provides critical information as you adjust the tracing options. The Settings tab is divided into several key areas, including trace controls and trace options. If you have previous experience applying bitmap filter effects in CorelDRAW or Corel PHOTO-PAINT, the PowerTRACE tools will seem like familiar territory. The left side displays a preview of your trace results, while the right side features two option areas.Īcross the top of the dialog box are viewing and zooming tools, and across the bottom are the Undo, Redo, and Reset buttons. The dialog box is divided into two areas. There are six modes that you can choose from, depending on your tracing requirements. Alternatively, you can adjust the settings in the PowerTRACE dialog box (shown below). You can instantly trace a selected bitmap and use the default settings by choosing Quick Trace from the Trace Bitmap list box, which applies the trace without opening the PowerTRACE dialog box. With a bitmap selected in CorelDRAW, PowerTRACE becomes available through the Trace Bitmap command on the property bar. If this is your first tracing experience, some advance orientation may help demystify the tools involved. A Primer on Vectorization with PowerTRACE
CORELDRAW GRAPHICS SUITE X7 ACADEMIC HOW TO
Along the way, you’ll learn how to use many of the powerful features engineered into PowerTRACE that make the process fast and efficient.
In this tutorial we’ll take you step-by-step through the process to convert bitmaps to vector images, demonstrating a bitmap-tracing project that will enable you to quickly produce an accurate two-color vector version of a logo design without the need of a vector converter. While some features might be available in previous releases, the tutorial will be fully applicable to CorelDRAW Graphics Suite X7 and higher. This tutorial has been written for CorelDRAW Graphics Suite X7.
