Wiki Code Error on _PRINTIMAGE

[NasaCow]

FYI

_printimage first code set throws a syntax error on line 24
_PRINTIMAGE - QB64 Phoenix Edition Wiki



Changed the offending line from:
_PUTIMAGE Page&, Prev&

To:
_PUTIMAGE (0, 0), Page&, Prev&

And all good!

Thanks for reporting @NasaCow,

the example has been corrected now, however only a comma is needed in front of Page& to designate the destination coordinate parameter is ommitted, which is slightly different from your solution:

_PUTIMAGE , sourceHandle&, destHandle& 'size full source to fit full destination area

_PUTIMAGE (dx1, dy1), sourceHandle&, destHandle& 'full source to top-left corner destination position

hence in your solution the Page wouldn't be scaled to fit the Preview, but it would simply put the Page in the top/left corner of the Preview, clipping areas of the Page, if it's larger than the Preview, which is probably not what you want for a print preview

There's always a catch when learning (didn't realize that option!) At least I got to understand it a bit better. Glad to give back

I am confused the Title of Thread is _PrintImage and yet we are talking about _PutImage?

Typo in Title? Thing is we were just talking about _PrintImage for printer so possibly someone confused _PutImage with _PrintImage?

And for the record _PrintImage only takes an ImageHandle&, ie one argument.

It's true, _PutImage comes in very handy getting ready to _PrintImage

The glitch was in the wiki page for _PRINTIMAGE, but the glitch itself happened to be in a line which contained _PUTIMAGE on it.  

_PRINTIMAGE -- the wiki page with the glitch.
_PUTIMAGE -- the line on that page that was glitchy.  

And that's the breadcrumbs that led to the title and the post being as they are.

Ah! thanks
