  • Different font sizes in Stage and Adobe® Reader?
    If the designer of a PDF form has set the font size value of form fields to “Auto“ CABAReT Stage as well as other PDF readers will calculate a suitable font size. However the calculation results of CABAReT Stage and the Adobe reader are different. Some users reported that this may lead to a very small font-size if the PDF form is printed with CABAReT Stage. We will likely fix this behavior of CABAReT stage until the next major release within the first quarter of 2007.

  • Why do I run into problems with Scribus pdf forms?
    Scribus uses a non declared font for form fields. The PDF spec does not allow this and CABAReT Stage is not able to react accurately. The problem was reported to the Scribus Bugtracker. We also think of implementing a workaround.

  • Why can't I edit form fields?
    Probably your form is protected by a owner-password and the functions for editing the form are not given free. Methods to enter the owner-password are not implemented in CABAReT Stage yet.
    CABAReT Stage copes with documents protected by a user-password with low (40-Bit RC4) and high (128-Bit RC4) encryption. The Acrobat 7.0 encryption (128-bit AES) is not supported yet..

  • What means the error message: Unable to load graphics library [GDI+ is required]?
    CABAReT Stage needs GDI+ (gdiplus.dll) to render forms. Windows XP and Vista contain this component, older Windows versions not.
    Download this component from  http://www.microsoft.com/downloads/details.aspx?FamilyID=6A63AB9C-DF12-4D41-933C-BE590FEAA05A&displaylang=en and install it into the 'bin' directory of your CABAReT Stage installation.

  • CABAReT Stage starts slowly with activated virus scanner?
    If your virus scanner also scans archives like JAR, ZIP, RAR files etc. it may be possible that it takes more time to start CABAReT Stage.
    Solution: Configure your virus scanner to exclude the CABAReT Stage installation directory.

  • Does CABAReT Stage support color gradients?
    Gradients can be declared in PDFs in a number of ways. CABAReT Stage can only display one of them. This is the Axial Shading gradient type. This is also one of the most used types.
    In many PDFs gradients are not declared directly but are contained in an embedded image. We display these of course. The program will replace a "real" gradient that cannot be displayed with a semi-transparent grey area.

FAQ Linux

  • How do I install the programm?

    There's no special installation program. To use the program, extract the archive to a directory of your choice. Start the program with the provided shell script cabaretstage.sh.
    Since version 3.0 the archive contains also a launcher cabaretstage, that enables you to open files from the desktop in an alreay running program instance that was previously started with the launcher. For the launcher to work it needs the information where to find the Java VM to use. For this you can set the environment variable CABARET_JAVA_HOME or JAVA_HOME accordingly. If none of the variables is set, the launcher uses the file /etc/jvm, that is already present on Debian-based systems. On other systems you create the file yourself. Sample /etc/jvm for a SUSE 10.2 default installation:
    Code:
    /usr/lib/jvm/jre-1.5.0-sun

    You can also create a starter for CABAReT Stage. Sample CABAReT Stage.desktop, if you've extracted the program to /usr/local:
    Code:
    [Desktop Entry]
    Version=1.0
    Encoding=UTF-8
    Name=CABAReT Stage
    Name[de-DE]=CABAReT Stage
    Type=Application
    Categories=Office
    GenericName=PDF editing
    GenericName[de-DE]=PDF-Bearbeitung
    Exec=/usr/local/cabaretstage-3.2/cabaretstage
    Icon=/usr/local/cabaretstage-3.2/cabaret.png 3.

  • CABAReT Stage doesn't start.
    Auf Systemen mit bestimmten Versionen der X-Bibliotheken starten Java-Anwendungen nicht. Als Fehlermeldung wird angezeigt:
    Code:
    xcb_xlib.c:50: xcb_xlib_unlock: Assertion 'c->xlib.lock' failed
    Das ist ein bekanntes Problem mit der Java Virtual Machine. Ein möglicher Workaround hierfür ist das Setzen einer Umgebungsvariablen:
    Code:
    export LIBXCB_ALLOW_SLOPPY_LOCK=1
    Detaillierte Informationen können im Sun Developer Network-Eintrag und im Eintrag der XCB-Mailingliste nachgelesen werden.

  • The 64-bit launcher crashes. What can I do?
    Sun's 64-bit Java VM unfortunately has a bug in version 1.5, which causes JNI programs that import zlib (directly oder indirectly) to fail. You can read the details in the Sun Developer Network entry.
    To circumvent the problem use the shell script to start the application or use a Java VM version 6.

  • Don’t you have RPM- etc. packages?
    RPM and DEB packages are planned, at the moment however all developers are busy with other tasks.

  • I thought JAVA code was platform independent?
    We use the SWT library from Eclipse.org for displaying the GUI. If possible the SWT library accesses platform dependent mechanisms. This approach has the advantage that SWT applications fit better in their "surroundings". By accessing native libraries on the other hand it may happen that the same JAVA code behaves differently on other platforms.

  • Why is form field text not displayed until I leave the field?
    You are using an older release of CABAReT Stage.
    If the font size of a field is set to the value "Auto", the font size is set to "0" during editing the text or combination field. On a MS Windows platform the value "0" leads to a suitable default font size. When using the GTK the font is displayed in a very small size. This problem has already been fixed. Change the font size value from "Auto" to another value to work around the problem or upgrade to the latest version of CABAReT Stage:
