Following features are allways implemented for mono-image annotation and evaluation:

• You may zoom, rotate and drag the image without flicker (Open GL)
• 3D mice (SpacePilot) are supported.
• Associate a detailed description of the image.
• Annotate details within the image using editable Markers
• Arrows, bolds, triangles can be used as markers
• Further geometrical objects (rectangles, ellipses, squares, circles, lines, contours) highlight structures within the image
• Export function for publications
• Measure angles.
  

Measuring is possible, if a micrometer factor is given for the optics combination you defined with your image.

• Measure Distances (straight line, irregular line)
• Borders (elliptical, rectangular, irregular shaped)
• Areas (elliptical, rectangular, irregular shaped)
• Volumes (Spheroid, Quboid)
• Shallow volumes (Cylindric, spheroidic)
• All measured items can be edited and configured

There is a multilingual help system included (e.g. popup - balloons). Currently German, English, Duch.

Transparency - an important feature for annotations

If there are area or volume measurements, it might be of advantage, if the corresponding description or marker are transparent, so that important image information is not covered.
For that purpose each item can be tuned correspondingly. You just click to the label and then you may do your settings in a convenient dialog box.

In that way, you may change the colors of the filling or label, their transparency and a lot of other things.

Cysts of Toxoplasma gondii in a brain.

In this pair of images you see, how transparent annotation may be used. The volume of the estimated spheroid does not cover important image informations like the sporozoids within the cystis. On the other hand, the information to be annotated with volume data is visible immediately.

With sliders you wll be able to set transparency as distinct as you like.
