The _CLIPBOARDIMAGE statement copies a valid QB64 image to the clipboard.
Syntax
- _CLIPBOARDIMAGE = existingImageHandle&
Description
- existingImageHandle& is a valid handle to a graphic QB64 image in memory, created with _NEWIMAGE, _LOADIMAGE or _COPYIMAGE.
- You can pass _SOURCE, _DEST or _DISPLAY to copy the current source, destination or active display pages, as long as they are valid graphic images.
- SCREEN 0 handles (created either with _NEWIMAGE or passed using _DEST while in a text screen) are not valid and will create an Illegal Function Call or Invalid Handle error.
- Keyword not supported in Linux or macOS versions
Availability
- Build 20170906/64 onward.
Examples
Example: Create a sample image and copy it to the clipboard:
SCREEN _NEWIMAGE(800, 600, 32) 'Create image in memory: canvas& = _NEWIMAGE(300, 200, 32) _DEST canvas& 'Draw some random rectangles: RANDOMIZE TIMER FOR i = 1 TO 100 LINE (-100 + RND * _WIDTH, -100 + RND * _HEIGHT)-STEP(RND * 150, RND * 150), _RGB(RND * 255, RND * 255, RND * 255), BF NEXT LINE (0, 0)-(_WIDTH - 1, _HEIGHT - 1), _RGB(255, 255, 255), B COLOR _RGB(0, 0, 0), _RGB(255, 255, 255) m$ = " Hello, world! " _PRINTSTRING (_WIDTH / 2 - _PRINTWIDTH(m$) / 2, _HEIGHT / 2 - _FONTHEIGHT / 2), m$ 'Show the image: _DEST 0 _PUTIMAGE (_WIDTH / 2 - _WIDTH(canvas&) / 2, _HEIGHT / 2 - _HEIGHT(canvas&) / 2), canvas& PRINT "Image generated."
