✨ DPDRAW — bestie edition ✨

NCAR GRAPHICS · section 3NCARG · ok so let me put you ON 💅

💖 NAME 💖

DPDRAW — the girl whose whole job is drawing a curve when you already have fractional coordinates and you are simply not doing smoothing today. No smoothing. None. We're drawing raw, periodt.

🌸 SYNOPSIS 🌸

CALL DPDRAW (XCPF,YCPF,IFVL)

🦋 C-BINDING SYNOPSIS 🦋

#include <ncarg/ncargC.h>

void c_dpdraw (float xcpf, float ycpf, int ifvl);

✨ DESCRIPTION ✨

ok so here's the tea, three arguments, all of them matter, let's go 🫶

  • XCPF — an input expression of type REAL. It's the X coordinate of a point in the fractional coordinate system. Lowkey ignored when IFVL = 2, she's just not needed for that one bestie.
  • YCPF — an input expression of type REAL. It's the Y coordinate of a point in the fractional coordinate system. Also ignored when IFVL = 2, same vibe.
  • IFVL — an input expression of type INTEGER, and she's the one telling us what kind of call this even is:
    • 0 → a "first-point" call
    • 1 → a "vector" call
    • 2 → a "last-point" or "buffer-flush" call

🎀 C-BINDING DESCRIPTION 🎀

The C-binding argument descriptions are literally the same as the FORTRAN argument descriptions. Same energy, different language. Slay 💅

🌈 USAGE 🌈

  • Use "CALL DPDRAW(XCPF,YCPF,0)" to do a "pen-up" move to the first point in a sequence of points defining a curve. ✏️
  • Use "CALL DPDRAW(XCPF,YCPF,1)" to do "pen-down" moves to the second and following points in a sequence of points defining a curve. 👑
  • Use "CALL DPDRAW(0.,0.,2) to terminate a sequence of calls, finish drawing the curve, and flush internal buffers. 🚽✨ (yes the quote is like that in the original, no I will not be fixing it, we do not touch the facts)

🔥 EXAMPLES 🔥

Use the ncargex command to see the following relevant examples: tdshpk.

That's it. That's the list. One icon, tdshpk, main character energy fr fr.

💜 ACCESS 💜

To use DPDRAW or c_dpdraw, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — preferably in that order, bestie. Order matters, don't be chaotic. 🌸
