pressure shapes dont work even in latest release 008

[Nirmal]

I changed the way jpen resolves the tablet input device type. Now it should detect the '3 buttons stylus pen (pressure)' as a stylus by default (instead of cursor).

OMG it works!....you the man Nicolas!....it works!!!...it works!!!...Hurray!
A HUGE thank you for all your time Karl and Nicolas, Alchemy ftw!

[Nicolas]

nice!

[crowline]

I ran jpen-2-100121, and (when i set the ld_library_path) my wacom device showed up in the input devices list, and the pressure sensitivity worked. I only had a minute tonight to work on it, but when I tried to run Alchemy with the command you listed, and the new jpen jar, pressure didnt work... Ill try again, and post more when i get a chance...

Here is my JPen Status report (when pressure had started working. Dont know if it is still useful or not...)

Edit your "Alchemy" script file (found on Alchemy (linux) application directory). Change it to:
---
#!/bin/sh
cd `dirname $0`
export LD_LIBRARY_PATH="./lib"
if [ -n "$JAVA_HOME" ]; then
$JAVA_HOME/bin/java -jar ./Alchemy.jar $*
else
java -jar ./Alchemy.jar $*
fi
cd $OLDPWD
---
Then run it and hopefully pressure shapes will work as expected. If not then copy/paste Alchemy output here.

Cheers!
Nicolas

[Karl DD]

Hi Nicolas,

Thanks for helping out with this.
Would it be better to make this the default "Alchemy" script?

Karl

[Nicolas]

hey Karl, yes... and the same for AlchemyOpenGL. BTW there is a new public jpen release containing the fix for the problem described by Nirmal: http://sourceforge.net/projects/jpen/files/jpen/2-100213/jpen-2-100213-lib.zip/download .
Cheers!
Nicolas

[Karl DD]

Thanks for that.
I've updated that for the next release.

Well, I have the same problem with pressure as well. My debug console output is this:

And when I tried using the Jpen app, no pressure would be deteced when I set the input device to stylus so nothing would draw. I have a latitude xt with a n-trig digitizer.

[Karl DD]

Nicolas might be able to give you an answer as to whether your hardware is supported.

[Nicolas]

jpen does not support n-trig digitizers, it currently supports only wintab digitizers.

It looks like the n-trig team is (finally!) working on wintab support:

Certain industry-standard applications such as Photoshop can Painter cannot register pressure of the pen.

This problem appears to be related to the WinTab API not being able to communicate properly with the digitizer output.

Our solution for issues related to the pressure sensitivity and the WinTab API are currently under development and is due to be released in mid-May 2010. If possible we may post Beta versions for testing earlier.

(Copied verbatim from http://www.n-trig.com/Content.aspx?Page=Bulletin_Board)

I guess we will have to wait and see...

Cheers!
