Introduction


• The repurposing of graphical data can be a challenge during the publications production process

• Graphic file formats can present varied issues leading to alternative transformation scenarios

• Data quality is a major consideration from a source and publishing perspective

• Using the optimum software solution during the production process will reduce costs and optimize quality

• Definition of Transformation: Convert graphic data to an open file format, add value to the graphic (annotations, hotspots), create compliant file format when required (S1000D, ATA)



Possible Data Sources

• Raster files• Legacy format• Scanned line art illustrations

• Intermediate format• Exported from 3rd party software, e.g. CAD• Photographs a good example, used as is, or traced

• Vector graphics• 2D or 3D CAD system

• Many formats are possible and used• Adobe Illustrator, CorelDRAW• PDF

• Embedded vector and raster data

KNOWLEDGE:The word Raster originates from the term 'raster scan,' which was how old CRT monitors displayed images, by magnetically steering a concentrated electron beam line by line to form an image.

KNOWLEDGE:Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygons—all of which are based on mathematical expressions—to represent images in computer graphics.



Introduction – Raster Data

• Raster legacy data still plays a significant role in the technical publications process• Analysis of raster data can prove to be beneficial• Optimizing production process

• Raster Data may require enhancements with the addition of hotspots• Larson utilize an Optical Character Recognition (OCR) technology to achieve

the requirement• Raster Data used as an intermediate format• CAD export• Photographic files

• Used as a template • The deliverable with added value such annotations



File Formats – Raster Data

• Raster File Formats• TIFF is the most common raster format for line art scans, usually using a

compression algorithm to reduce the file size• Other raster formats include:

• JPEG (Joint Photographic Experts Group)• BMP (Bitmap Image File)• PNG (Portable Network Graphic)• PCX (PiCture eXchange)• GIF (Graphics Interchange Format)

• TIP: Specifications compliance toS1000D etc.• Save the TIFF as part of a CGM file• It will retain its quality and properties• It can also be combined with Vector data

KNOWLEDGE - TIFF (Tagged Image File Format)Industry-standard method for storing scanned and other digital black-and-white, grayscale, and full-color images. Developed mainly for desktop publishing, TIFF has found applications in several other areas such as computer aided design (CAD), fax transmission. TIFF saves detailed image information with each pixel, resulting in a relatively large data file.



Clean-up – Raster Data

• Quality of the legacy scan - Considerations?• The text legibility for OCR purposes (hotspotting)

• TIP: clean up scans using the well known raster editors, for example Adobe Photoshop & Corel Photo-Paint• The scans sometimes contain sporadic pixels (Noise) not part of the main image• The pixels can be removed using software functions, for example

• Corel Photo Paint • Remove Noise

• Adobe Photoshop• Despeckle• Dust & Scratches



Photographic Information

• Photographs also play an important role in publications• Predominantly used as a maintenance type illustration• They can be used directly and annotated appropriately

• Alternative, the photograph can be used as a template• Traced to create line art version



Introduction - Vector Data

• Vector Data is also available in varied formats• In the majority of cases it is preferable to Raster Data, mainly for quality

reasons

• BENEFIT: Vector Data can be scaled and the quality is maintained, easier to edit• Vector Data, the most common sources:• CAD Systems• General Graphics Software



Vector Data (continued)

• Common Graphic File Formats• CGM (Computer Graphics Metafile)• AI (Adobe Illustrator)• PDF (Portable Document Format)• SVG (Scalable Vector Graphic)• Various CAD formats including – DWG, DXF, IGES etc.

• Specification driven industries will probably require the CGM format to be valid with S1000D and ATA• During the demonstration will look at all these formats

• Configurable Batch Conversion Tool• Auto-Hotspot – Raster and Vector• Save to CGM, SVG, PNG

• VizEx Edit• Convert files individually• Add value – hotspots and annotations• Save as CGM or SVG with interactivity• PDF is also an option but hotspots will be lost



Demo

Automated Graphic Transformation





VizEx Transform - Major Benefits

• Ideal for processing large raster and vector graphic archives• Process Raster files and add hotspot information via OCR

technology • Use a companion spreadsheet to add associated information

• Process Vector data from 2D CAD systems• Automatically remove extraneous information• Process layering information

• Useful if layers contain foreign language information• Automatically enhance with hotspot information

• Convert PDF to CGM or SVG• Convert CGM to SVG and retain hotspot information• Hotspot CGM graphics

VizEx Edit - Major Benefits

• Support import and export of major open 2D graphic formats• CGM• SVG• PDF

• Easy to use hotspot and annotation capability• Cost effective illustration tool for maintaining an illustration

archive• Isometric illustration features and tools• Fully standards compliant S1000D, ATA iSpec2200 etc.



Summary

• There are many opportunities to source information to produce your technical graphics

• The number of source formats is diverse • Selecting the appropriate one can be a challenge

• VizEx Transform and Edit optimize the process of graphic conversion and transformation• Both products support the primary graphic publishing formats

• We hope the webinar has provided you with useful and interesting information
