Conversion of Legacy Graphics

Conversion can be a "minefield" when dealing with legacy data. Loss of integrity and even loss of data are common challenges. Proprietary file types can wreak havoc when the software becomes unavailable. The aerospace industry has recently experienced such a condition. Yet, there are methods for conversion if you have the right tools and the right people.

O'Neil handles conversion work by several means:

• We have in-house programs that we've written that set up specific CGM profiles at program launch. These are built to customer specifications and are pulled from the industry standards. This provides an error-free conversion environment.
• CGM conformance is a useful check when a customer is bringing in CGMs from many sources and must check for varying levels of accuracy.
• Initially, we verify the customer's requirements and hard code them into our in-house program, so the illustrator starts with and exports to the correct CGM profile. Any chance for error is then eliminated and every CGM produced matches the customers requirements exactly.

We always recommend to our clients that illustrations be stored in a file type that is:

• Nonproprietary
• Standards based
• Containing usable geometric and textual data (image files are fine for presentation, but a good source file must be maintained)

Conversion of legacy material often requires more work than simply button-push conversion. O'Neil offers help with:

• Cleanup and enhancement of legacy content issues. Issues such as line weight, misspelled words, incorrect or disproportioned attaching hardware, etc., will be identified and corrected as found.
• Cleanup and enhancement of legacy file composition issues. The unpredictable CGM output of many applications poses many unique challenges at the individual file level. O'Neil is capable of assisting with many issues including:
• Archaic or proprietary files
• Tangency of lines and arcs
• Layers
• Groupings
• Issues that may require complete reconstruction to correct. These may not be identified until the work begins. O'Neil will identify these and allow our clients to determine whether they will deem them worthy of the investment.
