ATTR_PRINT_AREA_WIDTH
| Type: | Print attribute |
| Description: | Specifies the width of the output in millimeters/10. For example, an input of 1721 will result in a print area width of 172.1 mm. (In this case, width refers to the horizontal dimension of the paper when looking at it in portrait mode, regardless of the ATTR_ORIENTATION setting.) VAL_USE_ENTIRE_PAPER specifies that the output should use as much of the paper width as possible. VAL_INTEGRAL_SCALE forces the hardcopy output to be scaled to an integral multiple of its screen size, thereby preventing aliasing and distortion. |
| Types of Printing: | Graphics. |
| Data Type: | integer |
| Valid Range: | 1 to 7620, VAL_USE_PRINTER_DEFAULT or VAL_INTEGRAL_SCALE |
| Default Value: | VAL_INTEGRAL_SCALE |
| LabWindows/CVI Compatibility: |
LabWindows/CVI 5.0 and later |
Values
| VAL_INTEGRAL_SCALE | When applied to either the height or the width, VAL_INTEGRAL_SCALE ensures that the ratio between the object's height and width in dots on the hardcopy is the same as the ratio between its height and width in pixels on the screen. This prevents distortion. Using VAL_INTEGRAL_SCALE also ensures that, for both the height and width, the number of dots on the hardcopy is an integral multiple of the number of pixels on the screen. This prevents aliasing, in which screen lines are lost or duplicated in an uneven manner. If you use VAL_INTEGRAL_SCALE for both the height and width, the number of dots on the hardcopy will be identical to the number of pixels on the screen. If you use VAL_INTEGRAL_SCALE on just one dimension, then LabWindows/CVI may round down the other dimension to maintain the integral scaling. |
| VAL_USE_ENTIRE_PAPER | Use as much of the paper as possible. |
