RxSpotlight is the Windows-based solution for Raster Editing and Raster to Vector Conversion

RxSpotlight for Windows is the next generation of raster and hybrid editing software. Today most drawing information is stored on paper or aperture cards. By using scanning technology in combination with RxSpotlight for Windows, you can edit your drawings directly without having to convert them to a CAD format. RxSpotlight for Windows is an advanced program for raster, vector and hybrid editing, and raster-to-vector conversion of scanned raster images.

RxSpotlight for Windows is recognized for its superior editing and cleanup tools outside the CAD environment. RxSpotlight for Windows introduces true CAD-style editing of complex raster images. RxSpotlight for Windows is optimized for Windows up to Windows 8 and comes with many new and improved features.

The first true hybrid drawing editor and powerful raster-to-vector converter for any type of graphics: color, grayscale and monochrome.

RxSpotlight for Windows is a powerful hybrid drawing editor and raster to vector converter. Using RxSpotlight for Windows, you can edit, update and semi-automatically and automatically convert to vectors scanned maps, drawings, sketches and other graphics.

Hybrid drawings consist of a monochrome, grayscale and color raster images overlaid with vector elements. Multiple raster images can be loaded, and the number of raster images handled simultaneously is unlimited. RxSpotlight for Windows supports most raster formats.

Raster object selection in RxSpotlight for Windows makes raster editing as easy as vector editing.
Using RxSpotlight for Windows, conversion of raster lines into vector objects is simple. You can also opt to delete the original raster. Deleting an original raster line, arc, or circle does not destroy the continuity of any intersecting raster lines.

You can create raster copies of vector objects and add them to the raster image.
Clean up of raster noise is carried out using a selection of filters including: smoothing, thickening and thinning, speckle removing and hole filling.

Vector objects are created and edited using a selection of tools. Vector drawings can be imported into Spotlight or exported to AutoCAD DWG or DXF file 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.

Working with color and grayscale raster images

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 brightness, 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 conversion (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 conversion

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
