Compatibility

J-Painter is implemented as JDK 1.1 compatible applets and successfully tested with the following browsers: IE4, IE5, IE6, IE7, NN4.7, NN6.2, NN7.2, Mozilla 1.6, Firefox 1.5, 2.0 for Windows, with IE 5.0 and Safari on Mac OS. The tests have been performed with both native browser's Java engines (if such exist) and with Sun's Java Plug-in (JRE 1.3, 1.4, 1.5, 1.6).

Known problems and limitations

• JavaScript image saving method is not compatible with IE5 on on Mac OS because that browser doesn't support JavaScript to Java communication. Please use other save methods instead (upload, standard post) if you worry about compatibility with IE5 on Mac OS.
   
• The editor can't open Black/White (1-bit) PNG files if it works under JDK 1.1. To bypass this issue either convert your PNG files to 8-bit or 24-bit color images or ask your users to install a mordern Java engine (www.java.com).
   

An issue after the Windows XP security update

After the Windows XP security update published at the April, 2006 the browsers IE6 and IE7 ask users to click twice on each active component on web pages (applets, Active-X objects, etc..) before allowing to interact with the component.
