ImageMagick Reader / Writer for AviSynth v1.60

This plugin consists of two filters: ImmaRead and ImmaWrite. The former reads images and the latter writes images to your hard drive.

ImmaRead supports the following formats:

* bmp, bmp3/4, dds, dpx, gif, jng, jpg, jp2, mng, pam, pbm, pcx, pgm, png, pnm, ppm, psd, svg (partial), tga, tiff, webp and wmf;
* formats with an alpha channel: gif, jng, png and tiff;
* gif and mng animations, multipage ppm and tiff, multilayer psd;
* 8 bit grayscale images (any alpha channel that is present is dropped);
* vector images: eps, pdf and ps (you need to install GhostScript, for example 8.64 (gs864w32.exe) or more recent; might be convienient to install GhostView (gsv50w32.exe) too although that's not necessary);
* raw camera support (3FR, CR2, DCR, DNG, ERF, MEF, MRW, NEF, ORF, PEF, RAF, SR2 and X3F) (you need to copy the patched version of dcraw.exe which is included in this package in a folder, say C:\Program Files (x86)\dcraw, and add the folder as a PATH system variable in the environmental variables).

Note that raw files are not supported by ImmaRead, since they can be opened by the plugin RawSource.

ImmaWrite supports the following formats:

* bmp, bmp3/4, dds, dpx, gif, jng, jpg, jp2, mng, pam, pbm, pcx, pgm, png, pnm, ppm, psd (only one layer?), svg (partial), tga, tiff, webp and wmf;
* formats with an alpha channel: gif, jng, png and tiff;
* gif, mng and psd animations, multipage ppm and tiff;
* 8 bit grayscale (with or without an alpha channel) images;
* raw images: either RGB or YCbCr depending on the input (for YCbCr with the following order of the planes: Y,U,V);
* YUV4MPEG (y4m): 4:2:2, 4:4:4, 4:2:2, 4:2:0mpeg2, 4:1:1 and mono are supported as planar formats with the following order of the planes: Y,U,V [see y4m: http://wiki.multimedia.cx/index.php?title=YUV4MPEG2; http://linux.die.net/man/5/yuv4mpeg];
* vector images: eps/eps2/eps3, pdf and ps/ps2/ps3.

Note that ImmaWrite doesn't support svg, wmf, raw digital photos or multi-layer psd.

Grayscale images are opened as Y8. RGB images are opened as RGB32 (when there is an alpha channel present) or as RGB24 (if there is no alpha channel present). Other formats (such as CMYK) are converted to RGB.

You need the ImageMagick dll's in order to be able to use this plugin. They should be copied to some folder (any folder will do). You need to set the MAGICK_HOME variable to the location of ImageMagick dll's (under Settings -> System -> Advanced -> Environment Variables -> Add MAGICK_HOME as a user variable), or you need to provide it using the magick_home argument. Thus for example, magick_home = "C:\\WINNT\\system32".

Changelog in v1.60:

* updated to AVISYNTH_INTERFACE_VERSION = 6 (so the plugin requires AviSynth v2.60).
* updated ImageMagick libraries to v7.0.2-10 (ported code to MagickCore API 7.0).
* ImmaRead: grayscale images are opened as Y8, non-grayscale images as RGB24 (or RGB32 if there is an alpha channel present).
* ImmaWrite: added dithering methods "Riemersma" and "FloydSteinberg".
* ImmaWrite: added the new 2.6 colorformats for raw/y4m.
* ImmaWrite: the color option is changed to color_max.
* ImmaWrite: added quality and sampling_factor options for jpeg.
* ImmaWrite: added the compression option.

Enjoy ;-)
