GRAPHIC SET STRETCHMODE ModeExpr | |||||||||||||||
Remarks |
There are several operations in PowerBASIC which involve stretching or condensing images on bitmaps, most notably GRAPHIC STRETCH. As individual pixels must be added or removed, there is a good chance that the quality of the image will be degraded. However, if you describe the nature of the image by defining a StretchMode, you can substantially enhance the appearance. The default StretchMode is maintained individually for each DC. You can set the default mode with this statement, or retrieve it with GRAPHIC GET STRETCHMODE. Of course, you can also override the default StretchMode when you execute one of the affected statements. The 4 stretch mode equates are predefined in PowerBASIC.
