• WebCGM profile developed specifically for web delivery and adopted by
the S1000D Specification www.s1000d.org
• CGM required plug-in technology to view graphics in a web browser
• W3C - http://www.w3.org/Graphics/WebCGM/

11. Where is CGM used? – Industry Sector
www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
• Aerospace Space & Defense
• Automotive
• Oil & Gas
• Why these industries?
• CGM = open, non-proprietary, reliable data exchange
• The commonality – CGM Profiles = Validation
• More specifically industry profiles
• Aerospace & Defense = WebCGM
• Oil & Gas = PIP
• Automotive = WebCGM
• CGM is used for delivery, publishing and the display of graphics
• In the Oil & Gas sector CGM is predominantly used for data exchange and
display of geophysical information
• No requirement for web delivery or graphical hotspots

SVG the Specification
• XML based
• SVG 1.1 – Full
• SVG 1.2 – Tiny
• A subset of the Full specification
• Designed for phones, tablets etc.
• Technical illustrations only require a small percentage of attributes
available in the SVG Specification
• Version 2.0 of SVG released
• There is no impact on our current support of SVG

14. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
SVG is XML encoded
• Benefits:
• Based on the international open standard
• Structured information based on a schema
• In theory could be validated against a tailored
industry schema
• Caveats:
• Not designed for data exchange, result could
be interoperability issues
• The off-the-shelf schema covers the whole
specification
• A new profile schema would be required to
validate against specific attributes/elements

15. Where is SVG used? – Industry Sector

Graphics Conversion and Display
Overview

18. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Introduction – Conversion and Display
• The primary conversion scenario, CGM exported to SVG
• The main driver for the conversion, display SVG graphics in a web
environment without a plug-in
• CGM graphics display on the web was predicated on a plug-in
technology
• The ability to import SVG graphics is also important
• Primarily generated by Adobe Illustrator
• Our SVG data exchange experiences motivated the writing of
the TECH SVG profile
• The objective, standardize the elements we import and export from
our own software
• We published the TECH SVG profile, making it publicly available
• http://cgmlarson.com/pdf/TECH%20SVG%20Profile%20DRAFT%20V1.1.pdf

19. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Standardization and Technology
• Two-part strategy
• Standardization
• Develop guidelines for the import and export of SVG
• Publish guidelines with public access
• SVG Data Exchange Objective: Interoperability
• Technology
• Update our software to optimize SVG export and import
• Develop new and enhance existing product/s supporting SVG

20. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
• What is TECH SVG?
• A subset of the Full and Tiny Specification’s
• How will TECH SVG help?
• Defining a standard method of exporting and importing
SVG elements
• Improve data exchange quality
• What else are we doing?
• Socializing our strategy and encouraging 3rd parties to
participate
• Specifically talking directly to the Aerospace and Defense
communities
• Work in Progress
• Developing our products to be TECH SVG compliant
• COMPLETE
TECH SVG

21. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Converting CGM to SVG
• Exporting the CGM file, we only use a
relatively small portion of the SVG
specification
• However, there is an intersection with Full
and Tiny profiles
• We are currently optimizing the export
based on real life customer files
• Conversion Challenges
• File Size
• Embedded Raster Images
• Hotspots
• Line styles
• Fonts
SVG - Full
SVG - Tiny

22. www.cgmlarson.com

Displaying CGM and SVG files
• The display of CGM and SVG graphics would usually take place in
a web browser
• Traditionally the CGM graphic would be viewed using a plug-in
technology
• The web browsers abandoned the support for many plug-in technologies
• This strategy prompted the conversion of CGM files to SVG
• SVG files do not require a plug-in to view graphics in a web browser
• The latest development, Microsoft Edge based on Chromium can
support plug-ins, caveat, still investigating
• Larson has developed a technology to allow CGM graphics to
displayed in a web browser without a plug-in, VizEx View HTML5
Demo Later

23. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Displaying SVG
• As discussed, and demonstrated in the introduction SVG
is native to the HTML5 format
• Therefore it is very straight forward to display the SVG
graphic
• The only downside is you will have to build a viewing
environment for the SVG, e.g. toolbar
• Breaking news - We now support SVG in our ActiveX
control technology
• The result, one environment for all the important file formats
• CGM, SVG, TIFF etc. side by side

24. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Displaying CGM – Plug-in
• The new Microsoft Edge is developed using the Chromium platform
Google’s technology
• The new version of Edge enables an Internet Explorer emulation
• This is not a default setting, it requires enabling
• Enable via the ‘flags’ function
• The integration should allow you to run plug-ins, including the
Larson ActiveX plug-in
• Additional research and testing required to confirm functionality

Conversion and Display
Considerations & Implementation

27. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Main Topics
• Conversion - Raster image support
• Display Hotspots – Interactivity
• Use Case 1 – Hotspots
• Use Case 2 – Display

28. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Raster Images - Conversion
• CGM and SVG both support the embedding of images
• CGM will usually have a Group IV Compression (TIFF) embedded
• This is standard practice for hybrid CGM files
• SVG does not support TIFF, therefore only JPEG and PNG can be used
• Conversion?
• A hybrid CGM is converted to SVG
• The TIFF image will require conversion to either JPEG or PNG
• A large conversion task, samples should be checked for quality
• The vector elements will not be affected
• A hybrid SVG is converted to CGM
• The conversion should be good, because CGM supports JPEG and PNG

29. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Hotspots - Display
• Hotspots – embedded attributes, providing user interaction
with the graphic
• This could be simple feedback, for example an information tooltip
• The interaction could also be more complex, a link to another
graphic or text in a table e.g. Parts List
• CGM has a clearly defined method of writing hotspot
metadata
• The details are documented in the WebCGM profile
• http://docs.oasis-open.org/webcgm/v2.1/os/WebCGM21-
IC.html#webcgm_interactivity
• SVG the same functionality is possible, however, there are
multiple methods of defining a hotspot
• So why is the hotspot definition important?

30. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Hotspots – Display
• The risk of not having a clearly defined hotspot
attribute is interoperability
• The definition of a hotspot can have ramifications
• The SVG hotspot data is not recognized, the result difficult
to edit
• Will the hotspot work correctly in the viewer environment
• The benefit of TECH SVG, the hotspot attribute is
clearly and consistently defined
• Therefore, the software can write the attribute consistently
• The result improved interoperability

31. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Use Case 1 – Hotspots
• Case – Converting a CGM containing hotspots to SVG, interactivity
missing!
• When using the CONVERT CGM to Vector conversion tool the graphic was
converted incorrectly
• The hotspots did not work in the SVG
• The reason, legacy software from Autotrol and Intercap generated CGM
hotspot information in a non-conforming method (embedded)
• We developed functionality to recognize the embedded regions in the graphic
• The technology will now recognize the hotspot and include in the SVG file

32. www.cgmlarson.com
Copyright Larson Software Technology (c) 2020
Use Case 2 – Display
• Case – Displaying a CGM file in Chrome using the ActiveX control
• A customer who uses our ActiveX control asked if we knew of a
method of using with Chrome
• Chrome no longer supports plug-in technologies
• We did some research and discovered an extension that enables the
functionality
