Interface to PostScript.
To generate a Postscript (or encapsulated ps) file corresponding to a single image in a canvas, you can:
c1
. pad1
.The size of the Postscript picture, by default, is computed to keep the aspect ratio of the picture on the screen, where the size along x is always 20cm. You can set the size of the PostScript picture before generating the picture with a command such as:
You can set the default paper size with:
You can resume writing again in this file with myps.Open();
. Note that you may have several Postscript files opened simultaneously.
The output type allows to define how the PostScript output will looks like. It allows to define the page format (A4, Legal etc..), the orientation (Portrait, Landscape) and the number of images (zones) per page. The output type has the following form:
Where:
The following macro is an example illustrating how to open a Postscript file and draw several pictures. The generation of a new Postscript page is automatic when TCanvas::Clear
is called by object->Draw()
.
This example shows 2 pages. The canvas is divided. TPostScript::NewPage
must be called before starting a new picture.object->Draw
does not clear the canvas in this case because we clear only the pads and not the main canvas. Note that c1->Update
must be called at the end of the first picture.
This is the recommended way. If the Postscript file name finishes with "(", the file remains opened (it is not closed). If the Postscript file name finishes with ")" and the file has been opened with "(", the file is closed.
Example:
The TCanvas::Print("file.ps(")
mechanism is very useful, but it can be a little inconvenient to have the action of opening/closing a file being atomic with printing a page. Particularly if pages are being generated in some loop one needs to detect the special cases of first and last page and then munge the argument to Print() accordingly. The "[" and "]" can be used instead of "(" and ")" as shown below.
Example:
TPostScript support two color model RGB and CMYK. CMY and CMYK models are subtractive color models unlike RGB which is an additive. They are mainly used for printing purposes. CMY means Cyan Magenta Yellow to convert RGB to CMY it is enough to do: C=1-R, M=1-G and Y=1-B. CMYK has one more component K (black). The conversion from RGB to CMYK is:
CMYK add the black component which allows to have a better quality for black printing. PostScript support the CMYK model.
To change the color model use gStyle->SetColorModelPS(c).

Draw a Cell Array.
Drawing a PostScript Cell Array is in fact done thanks to three procedures: CellArrayBegin, CellArrayFill, and CellArrayEnd.
PostScript cannot handle arrays larger than 65535. So the Cell Array is drawn in several pieces.

Patterns definition.
Define the pattern ipat in the current PS file. ipat can vary from 1 to 25. Together with the pattern, the color (color) in which the pattern has to be drawn is also required. A pattern is defined in the current PS file only the first time it is used. Some level 2 Postscript functions are used, so on level 1 printers, patterns will not work. This is not a big problem because patterns are defined only if they are used, so if they are not used a PS level 1 file will not be polluted by level 2 features, and in any case the old patterns used a lot of memory which made them almost unusable on old level 1 printers. Finally we should say that level 1 devices are becoming very rare. The official PostScript is now level 3 !
