Hwp_TIFF

tiff.hwp
========

This plugin allows Hollywood to load and save images in the TIFF image format.

Usage is simple: Once this plugin has been installed, Hollywood will be able to
load *.tif images on the fly.

If you want to save images in the *.tif format, use one of the constants
#IMGFMT_TIFF,
#IMGFMT_TIFFJPEG, #IMGFMT_TIFFFLATE that this plugin makes available once
loaded. For
example:

    SaveBrush(1, "test.tif", 0, #IMGFMT_TIFF)

Note that #IMGFMT_TIFF and #IMGFMT_TIFFFLATE both use lossless compression.
#IMGFMT_TIFFJPEG,
however, is lossy. You can use the "Quality" tag to set the compression level in
that case. Palette images can only be saved using the #IMGFMT_TIFF and
#IMGFMT_TIFFFLATE
modes because JPEG doesn't support palette images.

The TIFF format	supports alpha channel graphics. If you want to load a TIFF with
alpha channel, simply set the "LoadAlpha" field to TRUE. If you want to save a
brush
that has an alpha channel using #IMGFMT_TIFF, the TIFF plugin will automatically
create a TIFF image with an alpha channel for you.

By default, palette-based TIFF images will be loaded and stored as true colour
images.
If you want to have the raw palette-based pixels instead, set Hollywood's
"LoadPalette"
tag to TRUE in commands like LoadBrush().

Note that when using Miniwood you need "imageio" library if you want to load or
save
TIFF images using JPEG compression. If you want to load or save TIFF images
using
Flate compression and you're using Miniwood, you need either "imageio" or
"compress"
library.


History
=======

Version 1.3:    (24-May-26)
- New [Linux]: Added build for the Linux arm64 platform
- New: Version string in the binary contains the precise CPU archicture
specification now, e.g.
  "x64-linux" instead of just "Linux"
- Change: The plugin uses Hollywood's inbuilt zlib now on all platforms for
reasons of consistency;
  this means that when using Miniwood you have to load either the "compress" or
"imageio" library
  if you want to load/save images using TIFF Flate compression
- Fix: Miniwood is now correctly handled for TIFF images using JPEG compression;
if you want to
  load or save TIFFs using JPEG compression with Miniwood you need to load
"imageio" library first
- Fix: TIFF image files using JPEG compression didn't work correctly with
Hollywood 11 on all
  platforms
  
Version 1.2:    (18-May-23)
- Change: Amiga installer will now also copy the plugins for all platforms to
Hollywood's linker
  plugins directory so that they can be easily linked to executables
- Change [iOS]: Added arm64 build for the iOS simulator and removed x86 build
for the iOS simulator
  because the iOS simulator is no longer compatible with x86
- Change [Android]: Removed build for 32-bit softfloat ARM; nobody uses this any
longer these days
- New [macOS]: Added build for macOS arm64 (Apple Silicon) 
- New: Added support for Hollywood 10's ability to get the image format name;
getting #ATTRFORMAT
  for images loaded using the plugin will now return "TIFF"
- New: Plugin supports Hollywood 10's user tag interface for file adapters now;
all user tags
  will be forwarded to the corresponding file adapters now
- New: Added support for adapter-specific file saving (requires Hollywood 10)
- New: Plugin can now save palette-based images now; this is only supported for
#IMGFMT_TIFF
  and #IMGFMT_TIFFFLATE; #IMGFMT_TIFFJPEG doesn't support palette-based pixel
data because
  JPEG doesn't support that; note that this feature requires Hollywood 9.0 or
better
- New: Hollywood 9.0's new "LoadPalette" tag is now supported

Version 1.1:    (01-Jul-15)
- New [Linux]: Added build for Linux ARM
- Fix [Linux/MacOS]: Plugin is now compiled as position-independent code (PIC)
- Fix [OS3]: FPU version will cleanly exit now in case there is no FPU
- New: Added support for adapter-specific file loading (requires Hollywood 6.0)
- Fix: IsPicture() didn't return correct width, height, and alpha channel
information
- New: Added support for writing JPEG and FLATE compressed images; use
#IMGFMT_TIFFJPEG and
  #IMGFMT_TIFFFLATE to access these new savers; the #IMGFMT_TIFFJPEG saver
supports the
  "Quality" tag and also alpha channel images (requires Hollywood 5.3)
- New: Added support for loading JPEG and FLATE compressed images (requires
Hollywood 5.3)
- New: Added file types information for Hollywood 5.3

Version 1.0:    (14-Apr-13)
- First release
