XCreateRegion(3)
okay bestie, welcome to the XCreateRegion(3) page π
this one lives in XLIB FUNCTIONS, and we're about to get regions handled β no cap.
π NAME π
Meet the trio: XCreateRegion, XSetRegion, and XDestroyRegion β their whole job is create or destroy regions. That's it, that's the vibe. π¦
β¨ SYNTAX β¨
Here are the exact signatures, bestie β keep them character for character:
Region XCreateRegion(void);
int XSetRegion(Display *display, GC gc, Region r);
int XDestroyRegion(Region r);
No vibes-based typo fixes, okay? π
π«Ά ARGUMENTS π«Ά
displayβ specifies the connection to the X server. This is your link to the X server, bestie. πgcβ specifies the GC. Yes, that's the whole note; the GC is the main character here. πrβ specifies the region. The region in question, periodt. π
πΈ DESCRIPTION πΈ
Okay so XCreateRegion creates a new empty region. Fresh out the box, empty, iconic. β¨
XSetRegion sets the clip-mask in the GC to the specified region. The region is specified relative to the drawable's origin. The resulting GC clip origin is implementation-dependent β so don't go assuming some specific value, bestie. π«Ά Once it is set in the GC, the region can be destroyed. Slay, that's the lifecycle.
XDestroyRegion deallocates the storage associated with a specified region. Basically it cleans up after the region so you're not just leaving storage hanging like confetti. π
