Improvement of DIAdem vector graphics output

Status: Declined

Hi Newton,

Thank you for your request. We discussed it in R&D. Because we have nearly no other similar feedback from other customers, we decided for now not to extend the current graphic output formats.

Greetings

We need to have vector based graphics output of DIAdem reports for importing into test reports, written in Word. The comparison of EML and EPS output format of DIAdem favoured the EPS in terms of print quality.

 

However, the EPS format is actually not vector graphics output but a pixel image, wrapped by a few lines postscript code. It's size is also about 1000 times bigger than the EML output of the same curve.

 

We also compared the DIAdem output with an old UNIX software suite, formerly used for a Versatec light beam plotter. The postscript output from the UNIX software has about half the size of the EML format, but the software can not easily ported onto recent systems.

 

It seems worthwhile to improve the capabilities of DIAdem for size-reduced real vector-based postscript output. The algorithm should be able to reduce the lines to be printed by optimization for a given printer resolution. Target should be the smallest possible output file.

Hi Newton,

 

Have you tried the EMF picture format?  That's a vector graphics format that DIAdem exports.

It was colleagues which tried EMF and they were not statisfied with its quality. The saw zig-zag at the edges of lines and this was their reason to prefer EPS. The PostScript as we know it from former UNIX times does not have zig-zag edges and can be upscaled w/o showing any rasterizing effects at all. Thats what we are looking for. Personally do I not know if EMF allows lossless scaling.
