Would this do it from an SVG perspective?

- Dear all,
- Thanks for all the replies I get.
- With the lights brought by your answers, I precise I was actually talking about background transparency, as I am looking at displaying the same graphics on black or white background.
- From the answers I get I understood that this is only available if the viewer/interpreter allows it when rendering; and this is not envisionned by CGM standard..
- For information, it appears also that SVG has not envisionned these features. It implements only the alpha transparency (equivalent to the Escape 45).
- Any comments
- Regards,
- Franck

- Objet : A CGM Question: handling transparency
- Dear all,
- I would like to ask to you (users, vendros, CGM experts, ...) some help on understanding the transparency management proposed by CGM
- I I have well understood the standard:
- - The TRANSPARENCY primitive is used to decide wether the Colour specified by AUXILIARY COLOUR primitives with the following behavior:
- - if TRANSPARENCY is set to off, all primitives (marker, filled area, text, pattern, ...) that needs to, use the AUXILIARY COLOUR for rendering for instance dash line.
- - if TRANSPARENCY is set to on, all the things to be rendered in the AUXILIARY COLOUR are then rendered as TRANSPARENT (nothing drawn)
- Then, It seems to me that I have the mean to display some of my graphics with transparent (no colour) parts. But I have not found the way to have the background of my graphics rendered as transparent.
- Any help, comment, suggestion will be appreciated.
- Last but not least, what is the tool support level of such features?
- Best Regards,
