A new version of PixelZoomer has been finished. The changes:

  • New: Real time zoom tool
  • New: Additional pixel info window at cursor

  • New: Selection can be filled with color
  • New: Option to exclude hash mark in eye dropper value

  • Removed: Java rendering (Windows XP/Firefox 3.* users: For Java, please use version 1.2.1 of PixelZoomer)
  • fixed some minor issues

This version is compatible with Firefox 5.

Version 1.2 / Version 1.2.1 released

This update is a port of PixelZoomer for Firefox 4 (Beta). The option for Java rendering has been added again with version 1.2.1 because in Firefox 3.6 and some systems, there still may occur differences when using the canvas method.

Version 1.1 released (Version 1.1.1 is a minor release)

PixelZoomer has received a first update which can be installed via Firefox or manually. The improvements of the new version at a glance:

  • PixelZoomer can now also be opened in a tab
  • a separate pan button in the toolbar
  • selections can be deselected
  • an undo/redo function
  • keyboard shortcuts can be modified
  • additional zoom buttons in the toolbar
  • the view is always being zoomed into the mouse pointer when zooming with the mouse
  • better scroll speed for larger window sizes
  • minor improvements

Have fun with the new functions!
