Once again, I think it has to do something with the png file having a
separate colour space. We had that discussion some time ago. Could you try
exporting it as jpeg and do the comparison again?

I've updated the download section of the Motif page
(http://wiki.documentfoundation.org/Design/Motif).

So the story seems to be this;
- Inkscape users aren't encountering any problem with the
alpha in the
SVG file (as demonstrated by Hillar, Rob and Sveinn)


This might be true, if you didn't add an opacity gradient to
the triangles.

If the plain opacity corresponds with the alpha values you
added to the triangles (and it doesn't seem so when I look
at your bitmap), I don't think there will be an issue.

I compared the bitmap you uploaded to the wiki with Sveinn's
svg:
http://wiki.documentfoundation.org/File:MotivScatter_comparison.png


There are small differences in opacity and color, but they
seem to be neglectable in my eyes.


The difference is even less disturbing on my Mint10 system 
(standard sRGB colorspace for the monitor); EyeOfGnome 
viewer versus Inkscape can be seen here:
Small file 
 
and full screenshot



Used the Gimp color picker to compare two spots from the 
screenshot (maybe 1-2 pixels off) and the difference was 
quite subtle.

EOG: RGB 189,217,128 --> Inkscape: RGB 186,215,120
This should be interpreted as an indication - not big 
science ;-)


Best regards

There might be an issue when the file is exported from
Inkscape to EPS - don't know if opacity is recalculated or
just exported to flat colors.

But for the moment we might stay with the files we have.

Best regards

Bernhard

Thanks, this keeps the triangles as vectors.

What I found out is:

The single triangles have a fixed opacity set instead of using the
alpha channel of the gradient definition.

This is certainly a bug - probably when exporting the file to SVG.

If there is no other possibility to turn the .psd file in SVG (I used
an online converter, leading to a 300MB large file that failed to load
in Inkscape), the only way to solve this properly would be to get the
gradient definition for each triangle from CS5 and add them manually
to the Inkscape triangle gradients. Together with correcting the
opacity of the objects this would mean to do three corrections on 56
triangles - probably about half an hour of stupid work, but manageable.

Hopefully it won't need to come to this =)


I don't own a CS5 copy, so I can't do this.

Anybody able to help out (or do just a part of it?)

Best regards

Bernhard

The whole point of making the motif was so we could start using it (like
Drew has started on another thread).

So let's get busy making Design material with them! =D
Whaddaya say?


Yes, please!



PS. I've written up some "guidelines" on the wiki page for the use of
the motif that I'll back up with example-images as I get time.
Let me know what you think ... Are they realistic? helpful? clear?


I would restrict rescaling to vector versions (if possible, of course).

I'd ask to be even more restrictive (with less exceptions):

Warping / distorting should be avoided at all

For recoloring a posting to the mailing list should be recommended.

I can imagine reasonable examples for modified colors, but these should 
be integrated in our general visual language.


Apart from that, they are realistic, helpful and clear :-)

Best regards

Bernhard

That's perfect Sveinn. I've uploaded your files and linked them on the 
motif page;

http://wiki.documentfoundation.org/Design/Motif
Thanks for your help with this and good luck with the tax-declaration. 
The only other thing that's certain in life, right? ;)

Sveinn, if I could get the ungrouped SVGs you created (but
without a
black background) off you that would be great, or feel free
to replace
the link on the wiki yourself if you have time.

I've updated the download section of the Motif page
(http://wiki.documentfoundation.org/Design/Motif).

So the story seems to be this;
- Inkscape users aren't encountering any problem with the alpha in the
SVG file (as demonstrated by Hillar, Rob and Sveinn)
- Anyone using Illustrator can use the original AI file to retain alpha
- Anyone who can't get it to work in either can still use the PNG file
which is high-res enough (2500x2500pixels, 300dpi) for the majority of jobs.

So I have provided these three formats on the motif page in the "Final
motif" download section.

Sveinn, if I could get the ungrouped SVGs you created (but without a
black background) off you that would be great, or feel free to replace
the link on the wiki yourself if you have time.
We can keep looking into a one-size-fits-all format solution, but I
don't want to waste everyone's time trying to get the file right.
In its current incarnations, it is usable without defects (in at least 1
of the three formats listed above).
The whole point of making the motif was so we could start using it (like
Drew has started on another thread).

So let's get busy making Design material with them! =D
