CThruView is an image viewer that allows mouse clicks to go through the image. Use it as tracing paper or splash screen. The image can be made semi-transparent, flipped, rotated, zoomed, always on top, clipped, moved, hidden and centered.
Some notes that might help other users: <br /> To get the click-thru function to work, de-select 'Movable' in the CThruView screen interface. <br /> The developer of CThruView recommends you run it under the older version 1.6 of Java Runtime Environment. This avoids glitches that occur when running under JRE 1.7. You can get Java Runtime Environment 18.104.22.168 (32-bit) at filehippo.com/download_jre_32/11227/ <br /> Once you have installed JRE 1.6, then: <br /> (1). Write new batch file and name it, say, cthruview_jre16.bat. This gives the path to the directory that the java.exe file is in, then gives the instruction to run cthruview.jar. Mine looks like this: <br /> pushd C:\Program Files (x86)\Java\jre6\bin\ <br /> java -jar cthruview.jar <br /> (2). Copy files cthruview.jar, appframework-1.0.3.jar and swing-worker-1.1.jar into the same \bin directory as the java.exe file. <br /> (3). Run the batch file from any location, such as the desktop. <br /> I use CThruView with 3D CAD software when reconstructing historical subjects. I use it to match old photos to perspective views of the model. Often this can work better than the perspective matching features within the CAD software itself. It is the only software that can do this.<br /> <br />
