Invoking Greyscale Printing

You can switch on the ability to create and print greyscale diagrams in Capital E/E Publisher. It is available for a number of the packagers including Capital Design Explorer, as well as the CGM, HTML, and S1000D Packagers.

To invoke greyscale printing change the relevant flag value to ‘true’ in or or in the \publisher\config.xml file located in your Capital installation.

Note

For advanced users ONLY the greyscale curve map can be adjusted using the settings available in the Capital home/config/cgmprops.xml file, if required. The greyscale curve map enables you to define the degrees of how light or how dark greys are rendered on your diagram. Setting the greyscale curve is optional. If no curve is defined, your output will have the same greyscale setting as the original input. For example, if an item was assigned the color of 64, 64, 64, then on conversion from greyscale the output would also be rendered as 64, 64, 64. Note that 256,256,256 is white and 0,0,0 is black.

In general if no curve map is defined the conversion from colors may result in greys that could be difficult to see on a diagram. The default greyscale mapping converts lighter colors to colors which are twice as dark. For example:

Copy

<point greyInput = '000' greyOutput = '000'/>
<point greyInput = '250' greyOutput = '128'/>
<point greyInput = '255' greyOutput = '255'/>

Using this greyscale mapping it is possible to set everything to either black or white, as shown below. Note that the threshold between black and white is set between 120 and 121 (120 and below is made black; 121 and above is made white). The threshold can be set to an alternative value if required.

Copy

<point greyInput = '000' greyOutput = '000'/>
<point greyInput = '120' greyOutput = '000'/>
<point greyInput = '121' greyOutput = '255'/>
<point greyInput = '255' greyOutput = '255'/>
