YAPF GIMP Plugin — Build Instructions
======================================

Requirements
------------
  - GIMP 3.0 or later (with development headers)
  - gimptool (included with GIMP 3 dev packages)
  - yapf.c and yapf.h must be in the SAME directory as yapf-gimp.c
    (the plugin embeds the codec via a direct #include)

  On Arch/Manjaro:    sudo pacman -S gimp
  On Debian/Ubuntu:   sudo apt install gimp libgmp3-dev
  On Fedora:          sudo dnf install gimp gimp-devel

Installation (automatic)
-------------------------
Open a terminal in this directory and run:

    $ gimptool --install yapf-gimp.c

This compiles the plugin and installs it into your GIMP plug-ins folder
automatically.  Restart GIMP and .yapf files will appear in the "Open" and
"Export As" dialogs under "YAPF image (*.yapf)".

Manual compilation
------------------
    $ gcc $(gimptool --cflags) -O2 yapf-gimp.c \
          $(gimptool --libs) -o yapf-gimp
    $ install -Dm755 yapf-gimp \
          ~/.config/GIMP/3.(your version here)/plug-ins/yapf-gimp/yapf-gimp

Notes
-----
  - The plugin registers two procedures: file-yapf-load and file-yapf-save.
  - Supported colour modes: Gray, Gray+Alpha, RGB, RGBA.
  - The MIME type is image/x-yapf and the file extension is .yapf.
  - RGB and RGBA images are saved with the sRGB GPU hint (YAPF_FLAG_SRGB)
    because GIMP's native 8-bit buffers are always gamma-corrected sRGB.
  - Mip levels are NOT generated on export — GIMP does not expose them.
    Use the YAPF C API directly if you need a mip chain.
