{{DISPLAYTITLE:_CLIP}}
|
|
The [[_CLIP]] option is used in a QB64 graphics [[PUT (graphics statement)|PUT]] to allow placement of an image partially off of the screen.
|
|
|
|
|
|
{{PageSyntax}}
|
|
:[[PUT (graphics statement)|PUT]] [[[STEP]]]({{Parameter|column, row}}), {{Parameter|image_array(start)}}[, [[_CLIP]]] [{XOR|PSET|AND|OR|PRESET}][, {{Parameter|omitcolor}}]
|
|
|
|
|
|
{{PageDescription}}
|
|
* _CLIP should be placed immediately before the PUT action if used. XOR is default when not used.
|
|
* The offscreen portions of the image will be the omit color.
|
|
* [[GET (graphics statement)|GET]] can get portions of the images off screen in '''QB64'''.
