4.3.1 Details on the color of the drawing
Unfortunately our converter cannot rely on the color details given in the input les, es-
pecially in the case of PDF les. Very often black/white les are marked as “full color”
les, which gives poor results in conversion. Here the user must examine the drawing
and decide which color palette should be used.
Press the “View selected le” button and view the le in the internal viewer. Then decide
whether the drawing is primarily black and white, grey-scaled or colored. Here it is a
matter of which color palette is important or which one predominates. If, for example,
only a logo is in color and the rest is in black and white, then you can specify that the
drawing is to be black and white and not colored.
4.3.2 Details on the scale of the drawing
Unfortunately, the details on the scale of the drawing are not given either in PDF or in
HPGL, DWF or TIFF, etc. Our Wizard requires your input on the scale. The coordinates
of the drawing are scaled on the basis of these details. If no details are given on the scale,
then these coordinates are output in plot or print units as appropriate.
The details on the scale of the drawing are used in various ways:
Method 1:
Press the “View selected le” button and view the le in our internal viewer. Look in
the table header of the drawing for the scale details and input the details that you have
found into the wizard. If the details given in the header are correct, then the coordinates
will be scaled correctly.
Method 2:
Press the “View selected le” button and view the le in our internal viewer. Activate
the measuring function in the viewer and measure a dimensioned section in the drawing.
Correspondingly input the values that were determined into the wizard. For example, if
a measured section of 15.8 m (15,800 mm) results in a measured section of 311.2, then
the scaling factor is 311.2:15800.
Method 3:
If you determine after the conversion that the coordinates show a considerable precision
error, then it is necessary to carry out a calibration operation using calibration points. The
calibration cannot be carried out in our Wizard. Instead you have to start the program in
the main menu and start up the OCR mode.
