Explore the power of superior raster editing tools!

RxSpotlight for Windows is the first true hybrid drawing editor and powerful raster-to-vector converter for any type of graphics: color, grayscale and monochrome. By using scanning technology in combination with RxSpotlight, you can edit your drawings directly without having to convert them to a CAD format. 

Raster Objects and Hybrid Graphics

Raster Object Selection enables you to select raster lines, arcs, circles using tools similar to those for vector selection (selecting by picking, window, polygon, fence, etc.). Now this technology has been improved even more. A raster object selected by any object method, now has “grips”, which allows you to modify its configuration, and it has a set of modifiable properties similar to those of vector objects – line style, width, etc. Prior to the latest RxSpotlight for Windows version, only vector objects had such properties. Now the program treats raster and vector graphics in the same way – for true “hybrid” graphics.

Unlimited Workspace

The RxSpotlight for Windows workspace used to represent a set of raster files and a vector drawing linked through the file-workspace, containing a set of references. Now you can create a workspace as an integrated file containing both raster and vector objects. In the new version the workspace “is unlimited”- a raster image of any size can be always inserted into the current workspace. All RxSpotlight for Windows objects have a Z-value (Elevation) and a sequence order. The capability of saving a RxSpotlight for Windows workspace to the *.DWG format preserves this data. RxSpotlight for Windows uses a modern multi-document (MDI) interface that allows you to work with several workspaces simultaneously.

Work with color and greyscale raster image

You can crop color and grayscale raster images, change their resolution and scale, deskew them, and eliminate linear and nonlinear deformations using the calibration procedure. You can change  rightness, contrast, hue and saturation, and adjust the color gamut of an image using a histogram, improve image quality, or apply a set of color filters (Blur, Unsharp Mask, Median). You can draw on these images and create raster objects by rasterizing vector objects to color raster, and merge monochrome raster images with color ones. The new versions now have functions that before were only applicable to monochrome raster images: for example, tracing (semi-automatic interactive raster-to-vector conversion) color and grayscale images.

New capabilities of semi-automatic raster-to-vector convertion (tracing)

In addition to simple graphic object tracing the new version can now trace raster shapes that correspond to vector templates. You just need to select a raster shape, and the program will try to recognize it and match it to an appropriate vector object – a sample from the loaded library – symbolic notations on scanned electrical circuits and process charts, maps, etc. A significant enhancement to the polyline tracing is the new auto-detection of direction at intersections.. If you have not chosen a direction during a specified waiting interval, the program will continue tracing in the automatically defined direction by itself.

Automatic raster-to-vector convertion

Improved algorithms for automatic raster-to-vector conversion allow converting scanned drawings to CAD-files one by one or in a batch mode, even overnight. The improved conversion options allow precise tuning to achieve the most accurate vector representation of source files. The resulting drawings consist of lines, polylines, arcs, circles, texts and shapes (blocks). Line styles, widths, text height, hatch styles are preserved. RxSpotlight now provides automatic conversion of raster shapes to specified vector samples. Built-in OCR recognizes text strings on the drawings.

Vector enhancement tools

RxSpotlight for Windows has a comprehensive set of tuning tools for autocorrection of vectors obtained after raster-to-vector conversion, specialized functions for editing vectors – for example, merging a group of vectors to the object of a given type (some segments to an arc or circle), cropping, extension, etc. One very powerful tool is Vector Object Search and Replace, which works on vectors (i.e. CAD-files). For example, it is possible to find and replace with standard symbols all fasteners on a mechanical drawing or all windows and doors on a floor plan, etc.

Flexible User Interface!

Most other raster-to-vector converters have a complex user interface with a frightening number of buttons and toolbars, but with no possibility to create your own working environment by altering the layout or by removing unnecessary commands and buttons. In the new RxSpotlight for Windows, you can drag using the mouse, lists, menu items, arranging your own toolbars.
