 Someone else is experiencing the same problem?

That sounds similar to a problem with numptyphysics which I think was fixed, 
though I don't know the details. That used to draw lines from the last point 
of pen up rather than the first pen down. I certainly don't see this with the 
sketch app in FSO MS 4.1.

I think the problem is not on your soft, but in our driver. We were 
experiencing the same problem in other programs too.
Thank you the same for the hints. It can help us for other situations.

Yes, I remember too.
I think I have to do a good format / reinstall :)

 MyPaint.

I highly doubt that the fr is able to do that - the graphics tablets I know rely
on a stylus with a special tip with suspension to achieve different pressure
levels, so I don't think it is possible with a normal resistive touchscreen.

Resistive touchscreens have a completely different operating principle to 
graphics tablets, so you can't make that assumption. It would be like assuming 
a guitar pick would work as a stylus on an iphone because it works on gta02.

It seems there is pressure info available from the hardware, but that it's not 
been possible to get it consistent over the whole screen. For more on what's

MyPaint 0.6

2009-02-02 Thread Michele Renda
Hello to all

First of allI want to say thank you to Martin Renold, that has created a 
very good program to extract the artist inside us :)

His program, is called MyPaint, and when I saw it, I thinked direct to 
Openmoko Freerunner. I found on GetDeb the package for architecture i386 
and amd64, prepared by Joao Pinto. I took the .dsc and the tar file, and 
I compiled with a debuild.

The package compiled perfectly on FR whitout any changes, and in a few 
of minutes I had my .deb for armel4.
They did a perfect job :)

I tried the application on FR and this was the result:
[1] 
http://dl.getdropbox.com/u/562269/MyPaint/2009-02-01-050308_480x640_scrot.png
[2] 
http://dl.getdropbox.com/u/562269/MyPaint/2000-02-01-051141_480x640_scrot.png

It run pretty well. It is fast enough (in Debian  XFCE). If would be 
nice if someone would make a opkg package.
The only problem was the sensitivity of the touchscreen. It happen that 
when a person put the pen UP the screen continue to
think  that it is still down. I think it can be fixed by software, but I 
am not so sure!

If you want to try it but you don't want to compile with debuild, here 
there is the precompiled package:

[deb]:
http://dl.getdropbox.com/u/562269/MyPaint/mypaint_0.6.0-0%7Egetdeb1_armel.deb
[tar.gz]:  
http://dl.getdropbox.com/u/562269/MyPaint/mypaint_0.6.0.orig.tar.gz
[diff.gz]: 
http://dl.getdropbox.com/u/562269/MyPaint/mypaint_0.6.0-0%7Egetdeb1.diff.gz
[dsc]: 
http://dl.getdropbox.com/u/562269/MyPaint/mypaint_0.6.0-0%7Egetdeb1.dsc

Best regards
Michele Renda

Ps. If you reply, do reply all, to keep the cc persons, that are not in ML.

these look as if the FreeRunner’s touch screen actually gives pressure
input to the application. Is that really the case?
