Opacity adjustment and export of multi-page pdfs not possible?

General usage

(using 6.1.1 on Windows 10)

Hello,
I looked into the issues of adjusting opacity in 2D plots and exporting multiple figures to one multi-page PDF-file quite extensively and at this point I am pretty sure, these features are simply not implemented in Scilab. Is my Assumption right or did I miss some functionalities?
Thanks for your comments,
Yann

Hello,

Scilab does not handle TrueColor model (only RGB indexed colors) in general. The only entity handling RGBA is the Matplot entity (see Matplot - 2D plot of a matrix using colors).

Multipage pdf are not supported.

Although the request is about 2D plots, you probably may find following link useful.

Thank you for your answer @mottelet

I have a follow-up question on this topic.
Is it possible to commission someone to programme the said functionalities for a fee?

@yann: I am sorry but adding opacity in the general Scilab graphic model is a HUGE work beause it would necessitate to revamp the whole renderer module and it cannot be something else than a long term milestone. However, if you can afford to hire a Java/C++/OpenGL specialist we would be glad to help him to dive into Scilab project!

@mottelet: That really does sound like a big project to tackle and unfortunately probably out ouf scale for us as well then.

Would adding multipage PDF support mean a similar amount of work or could that be done on a smaller scale?

I think so. Stay tuned.

OK, keep me informed about the fitness of the toolbox to your usecases.
