SOURCE
From QB64 Wiki
The _SOURCE statement establishes the image SOURCE using a handle created by _LOADIMAGE or _NEWIMAGE.
- _SOURCE handle&
Description:
- The handle is a LONG integer value from the _SOURCE function or a handle created by _NEWIMAGE.
- If the handle is designated as 0, it refers to the current SCREEN image.
- A source image can only supply information to a program. POINT and GET might require a source other than the present one.
Code Examples:
SCREEN 13 a = _NEWIMAGE(320,200,13) _DEST a PSET (100, 100), 15 _SOURCE a _DEST 0 PRINT POINT(100, 100)
15
- Explanation: Create a new image with handle 'a', then use _DEST to define the image to draw on. Draw a pixel then set the source to 'a' and use POINT to show what color is in that position. White (15) and is the color set with PSET. Use _DEST 0 for the screen to display the results.
