[scribus] another API question - quick one

Dear Greg and List,

inspired by your mail, I went and created a testing document with one
object which I filled with a solid colour and experimented with
combinations of settings.

I found that in the properties window, there is Colours-tab with
Fill-tab (Fill Mode is "Solid") and I have Shade, which translates in my
.sla <PAGEOBJECT .../> to entries like this:

Shade 15%  >>>  SHADE="15"
Shade 40%  >>>  SHADE="40"
Shade 100% >>>  no entry


Then below there is Transparency-tab with Solid-tab and I have Opacity,
which translates in my .sla <PAGEOBJECT .../> to entries like this:

Opacity 100% >>> no entry
Opacity 75% >>> TransValue="0.25"
Opacity 60% >>> TransValue="0.4"
Opacity 40% >>> TransValue="0.6"
so this one is working "backwards"; because of the definitions of
opacity versus transparency I suppose


I had found in the help about the API the command that you also gave me,
namely

setFillTransparency(transparency, [name])

which I believe belongs to the first series above called "Shade".


I am still looking for a command which gives me access to the second
series called "TransValue". Why? Because in my little video-animation it
would give me a very sexy way of fading-in my text (the proverb), while
the ants are marching below.

I found another command which controls in the Text-Properties, Colour &
Effects-tab "saturation of colour of text fill" (0 - 100%) but that is
not nice for fading in, because a low saturation gives me ugly white
text on top of a coloured background. In contrast, a low opacity value
gives me almost invisible text on top of coloured background and then
gets nicely more and more visible.



I somebody could please point me to the online folders, where all the
scripter "commands" are created/hosted, I could learn to "read the
source" - not for programming, but for spying into all available
commands. Then I would not need to bother this list with my API questions.

I remember that I did this once, a good while ago, when I needed to find
details about png-bitmap exports. It took me a lot of time, but gave me
valuable details I believe.


Thanks. Sorry it got long again, subject line is now a lie...

Martin
