<aResolution>
<aResolution> is a 2-element array holding numeric values which define the print resolution in X and Y direction {<nDPI_X>, <nDPI_Y>}. The unit is Dots
Per Inch. Valid values can be obtained via the :resolutions() method.
Method XbpPrinter():setResolution() Foundation
Retrieves or sets the print resolution.
Syntax
:setResolution( [<aResolution>] ) --> aResolutionOld | NIL
or
:setResolution( [<nResolution>] ) --> aResolutionOld | NIL
Parameters
<nResolution>
Alternatively, the method accepts as a parameter a #define constant from XBPDEV.CH. The following constants are available:
#define constants for :setResolution()
| Constant | Description |
|---|---|
| XBPPRN_RESOLUTION_DRAFT | Prints in draft mode |
| XBPPRN_RESOLUTION_LOW | Prints in low resolution |
| XBPPRN_RESOLUTION_MEDIUM | Prints in medium resolution |
| XBPPRN_RESOLUTION_HIGH | Prints in high resolution |
Return
The method returns the previous setting in form of an array similar to the parameter <aResolution>. If the printer does not support setting this option, this method returns NIL.
Description
The method determines the resolution of printed output. A higher resolution improves the quality of what appears on paper but requires more time until a print job is finished.
