- and the line chart.
WD Magnifier Complete examples (WINDEV): WD Magnifier
[ + ] This example enables you to zoom part of the screen with a magnifier.
The maximum zoom value is set to 8.
Summary of the example supplied with WINDEV:
The WLanguge function named dCopyBlt() and the WLanguage property named ..Opacity allow you to perform a capture of the Windows desktop at the location of a window without this window appearing in the screen shot.
This example uses this tip to zoom the part of the screen found below the magnifier.
