Resolution Input - Pixels Per Length

Put in the correct resolution for the test to start the test:

device pixels per

The size of the document is given in cm.
Sizes of objects within the document are given in cm or px .

The appearance of the px value depends on the resolution.
This results from an input either directly with GET parameters or with an XHTML-form.
If there are no parameters set within the URI, the XHTML-form is provided.
If the viewer does not interprete XHTML, the parameters have to be added directly as GET parameters:
px is for pixels
l is for the length
u is for the unit.
The default is ?px=900&l=230&u=mm
This is a typical resolution for notebooks.
Another typical parameter set: ?px=99&l=1&u=in

Values with different units can be converted into the same unit system before a continuous animation can take place - or an interpolated presentation value is a combination of values of different units, that have to be converted into one value in device pixels to be presented.

The blue circle has a red comparison below, using only cm as units, no mix of different units. If something red gets visible, an error is occured.

Another testing option is the size of the black stroked square - width and hight have to be 15cm.
