Tk_GetPixmap(3)

💅 Tk_GetPixmap, Tk_FreePixmap — allocate and free pixmaps 🎨

ok so welcome to the Tk_GetPixmap(3) glow-up bestie, this is a page from the Tk Library Procedures and it's literally about making pixmaps and then yeeting them into the void ✨

---

✨ SYNOPSIS ✨

like, here's the whole vibe upfront:

#include <tk.h>

Pixmap
Tk_GetPixmap(display, d, width, height, depth)

Tk_FreePixmap(display, pixmap)

that's it, that's the whole thing, no cap 🫶

---

🎀 ARGUMENTS 🎀

• Display *display (in) — the X display your pixmap lives on. that's its whole home 🏠
• Drawable d (in) — the pixmap or window where your new pixmap is gonna be used for drawing. like, where it's gonna perform 💅
• int width (in) — width of the pixmap. how wide. the width-ness 🦋
• int height (in) — height of the pixmap. vertical era 🌸
• int depth (in) — number of bits per pixel in the pixmap. yes bestie, bits per pixel, that's the depth 🔥
• Pixmap pixmap (in) — the pixmap to destroy. rip bozo 💀

---

💖 DESCRIPTION 💖

okay so here's the tea: these procedures are identical to the Xlib procedures XCreatePixmap and XFreePixmap, except — and this is the iconique part — they have extra code to manage X resource identifiers so that identifiers for deleted pixmaps can be reused in the future. it's giving resource recycling, we love to see it ♻️✨

⚠️ and like, this is the important bit bestie: it is important for Tk applications to use these procedures rather than XCreatePixmap and XFreePixmap. otherwise long-running applications may run out of resource identifiers. and not to be dramatic but running out of resource identifiers is literally the worst 😭 so pls, use these ones, i'm begging 🥺

Tk_GetPixmap creates a pixmap suitable for drawing in d, with dimensions given by width, height, and depth, and returns its identifier. so you give it the deets and it hands you back your little pixmap ID 🎁

Tk_FreePixmap destroys the pixmap given by pixmap and makes its resource identifier available for reuse. so it's not just gone, its ID gets to be a main character again later 👑🦋

⭐ KEYWORDS ⭐

pixmap, resource identifier — that's the whole tag list, iykyk 🔑

and that's the page!! 🧚💜 this was Tk, version 4.0, from the Tk_GetPixmap(3) manual — go forth and manage your resource identifiers responsibly bestie, mwah 💋🎀
