💖 PGFplatform.h(3) 💖

okay bestie, so this is a page from libpgf's manual — it's PGFplatform.h, the header where all the platform-specific stuff lives. no cap, it's giving very "under the hood" energy but we're gonna get through it together 🫶

✨ NAME ✨

PGFplatform.h — PGF platform specific definitions. literally what it says on the tin, bestie 💅

🌸 SYNOPSIS 🌸

#include <cassert>
#include <cmath>
#include <cstdlib>

🎀 Macros 🎀

  • __PGFROISUPPORT__ — yes queen, ROI support is on 💖
  • __PGF32SUPPORT__ — and 32-bit support too ✨
  • WordWidth 32 — that's WordBytes*8.
  • WordWidthLog 5 — the ld of WordWidth.
  • WordMask 0xFFFFFFE0 — the least WordWidthLog bits are zero.
  • WordBytes 4 — that's sizeof(UINT32).
  • WordBytesMask 0xFFFFFFFC — the least WordBytesLog bits are zero.
  • WordBytesLog 2 — the ld of WordBytes.
  • DWWIDTHBITS(bits) — aligns scanline width in bits to a DWORD value.
  • DWWIDTH(bytes) — aligns scanline width in bytes to a DWORD value.
  • DWWIDTHREST(bytes) — that's DWWIDTH(bytes) - bytes.
  • __min(x, y) — the little guy 🥺
  • __max(x, y) — the big guy 👑
  • ImageModeBitmap 0 — bestie, this is image mode 0 💅
  • ImageModeGrayScale 1
  • ImageModeIndexedColor 2
  • ImageModeRGBColor 3
  • ImageModeCMYKColor 4
  • ImageModeHSLColor 5
  • ImageModeHSBColor 6
  • ImageModeMultichannel 7
  • ImageModeDuotone 8
  • ImageModeLabColor 9
  • ImageModeGray16 10
  • ImageModeRGB48 11
  • ImageModeLab48 12
  • ImageModeCMYK64 13
  • ImageModeDeepMultichannel 14
  • ImageModeDuotone16 15
  • ImageModeRGBA 17 — no, there is no 16, don't ask, it's just the vibe 😭
  • ImageModeGray32 18
  • ImageModeRGB12 19
  • ImageModeRGB16 20
  • ImageModeUnknown 255 — the mystery era 🌈
  • __VAL(x) — the wrapper ✨

🦋 Detailed Description 🦋

🔥 MACRO DEFINITION DOCUMENTATION 🔥

here come the receipts, every macro with its actual value and exactly where it lives 👑

#define __max( x, y)

Value:

((x) >= (y) ? (x) : (y))

Definition at line 92 of file PGFplatform.h.

#define __min( x, y)

Value:

((x) <= (y) ? (x) : (y))

Definition at line 91 of file PGFplatform.h.

#define __PGF32SUPPORT__

Definition at line 67 of file PGFplatform.h.

#define __PGFROISUPPORT__

Definition at line 60 of file PGFplatform.h.

#define __VAL( x)

Value:

(x)

Definition at line 603 of file PGFplatform.h.

#define DWWIDTH( bytes)

Value:

(((bytes) + WordBytes - 1) & WordBytesMask)

aligns scanline width in bytes to DWORD value 🎀

Definition at line 84 of file PGFplatform.h.

#define DWWIDTHBITS( bits)

Value:

(((bits) + WordWidth - 1) & WordMask)

aligns scanline width in bits to DWORD value ✨

Definition at line 83 of file PGFplatform.h.

#define DWWIDTHREST( bytes)

Value:

((WordBytes - (bytes)%WordBytes)%WordBytes)
