: - Will there be support for AlphaBlending (alpha/transparent channel) on
: hardwarebase? (Of course it would be hard to do a software alphablend on
: a running tv picture in the background, when displaying menus ;-) )
: (currently cmap.transparent is set to NULL in the framebuffer source).
Currently, the driver model is setup for alpha blending and other forms
of blitting, but all implementations are software-only. It isn't a big deal
to recode the SCREENDEVICE driver to talk to hardware to do this.
:
: - Settop boxes normally only have an infrared remote - no keyboard (even
: if an ir keyboard is possible - but not standard for everyone);-)
: Are there plans to support IR devices?
My recommendation is that the IR device be interfaced with Microwindows
to look like a keyboard device. In this way, either special MWKEY_xxx
keystrokes or regular characters can be generated by a keyboard or a
remote control device. This also is just a KEYBOARD driver in Microwindows,
and not a big effort.
: - Can microwindows be stripped of unused functions? (reason: only
: 7 MB of flash memory for the complete system (kernel, libs,
: applications, data).
Yes, see the src/config file, as well as include/device.h for easily
reconfigured
options. The design is to be able to make Microwindows quite small.
: - I couldn't find any clear pointer on the API (only the architecture
: docs)
There's a couple of web sites with good Nano-X documentation,
I can also send you a couple of programming tutorials, there's also
one on the site. The Win32 API is exactly compatible with Windows
for what is actually implemented.
: Are there more detailed docs, on the microwindows API (not the NANO-X,
: or
: WinAPI) - or am I totally wrong here?
The "microwindows" API is win32, and the other API is Nano-X, which
is Xlib-like, but not Xlib directly compatible. I have an unreleased project
where Xlib calls are directly translated to Nano-X calls, which seems to
work well except for stuff related to the color model and visuals.
:
: - Is there support for freetype (true type fonts)?
Yes, this is enabled by example in the Configs/config.ft config file.
We also support Adobe Type 1 scalable fonts and compiled
in fonts with a .bdf file converter.
