This operation returns the characteristics of lines drawn with WINPRINT-GRAPH-DRAW.
The printer must be open to perform this operation. It must be called prior to WINPRINT-GRAPH-DRAW. Once executed, the pen specified will apply to all graphic operations until a new call is executed. The selected pen is released when the printer is closed and will not affect subsequent print jobs. WPRTDATA-PEN must be initialized before use. There is no limit to the number of times this operation may be called.
WINPRINT-GRAPH-PEN has the following values:
| WPRTDATA-PEN-WIDTH | Specifies the thickness of the line drawn using WINPRINT-GRAPH-DRAW. The default unit of measure is pixels. For example,
if WPRTDATA-PEN-WIDTH is set to
0, the width will be one pixel, unless another unit of measure has been selected. The default value is
1.
The actual size of this measurement is affected by the target printer's resolution. This means that a width of 5 will appear differently on a printer with a resolution of 300 dots-per-inch (DPI) than it will on a printer with 600dpi. Consider the unit of measure relative to the resolution of the targeting printer before printing. |
| WPRTDATA-PEN-COLOR | Specifies the color of a line drawn using WINPRINT-GRAPH-DRAW. The color resolution (COLORREF) is a combination of Red, Green,
and Blue (RGB). The intensity of each color in the mix is determined by a number between
0 and
255. The default color (0,0,0) is black.
See your Windows API documentation for more information about RGB colors and COLORREF values. |
| WPRTDATA-PEN-STYLE | Specifies the type of line drawn. It may be set to one of the following values: |
| WPRT-PEN-SOLID (default) | Draws a solid line in the color selected in WPRTDATA-BRUSH-COLOR. |
| WPRT-PEN-NULL | Draws an invisible line. The background layer will show through. |
| WPRT-PEN-DASH | Draws a line of dashes (------). WPRTDATA-PEN-WIDTH must equal 1 to use this style. |
| WPRT-PEN-DOT | Draws a line of dots (......). WPRTDATA-PEN-WIDTH must equal 1 to use this style. |
| WPRT-PEN-DASHDOT | Draws a line of alternating dashes and dots (-.-.-.-.-.-.). WPRTDATA-PEN-WIDTH must equal 1 to use this style. |
| WPRT-PEN-DASHDOTDOT | Draws a line of dashes followed by two dots, (-..-..-..-..-..-..). WPRTDATA-PEN-WIDTH must equal 1 to use this style. |
| WPRT-PEN-INSIDEFRAME | Draws a solid line inside of the actual geometric area of the shape. |
See graphprn.cbl for examples of printing graphics. This example will draw lines and shapes with a solid pen that is 10 pixels thick:
INITIALIZE WPRTDATA-PEN.
MOVE WPRT-PEN-SOLID TO WPRTDATA-PEN-STYLE.
MOVE 10 TO WPRTDATA-PEN-WIDTH.
