4Iolayer:
5- Add scalar/mmap to iolayer
a106216b 6- Add close() code to iolayer for fakeseek sources.
b921d414 7- Merge callback interface into iolayer
a106216b
AMH
8- and raw
9- Implment the maxread threshold (Indicates how much can
10 be read from a source before it stops reading from its
11 underlying source. For making sure only the relevant
12 data is read from a socket for example.

15Enhanched internal structure:
16
17MultiImage & metadata support:
18- Figure what interface should be between C and perl?
19- How to store data in the C interface for tags/metadata?
20 Support tiff's madness, i.e. tags and options.
21- Error handling, make a general i_errstr object and arrange
22 such that each image has an i_errstr object to hold its
23 local errors?
24- SEE design/represent.txt for proposed new structure and
25 interface design that takes these factors into account.

26- define common i_* tags for specifying attribute common among images
27 like spatial resolution (implement for other image types, especially
10461f9a
TC
28 TIFF) (Spatial resolution is supported for all types that support
29 it - are there any other common properties we can add?)
faa6fa9b 30- implement the i_incomplete tag for other formats

32New Features:
a106216b 33- Add mng support, pcx and aalib support.

34 - Windows icon files (.ico)
35 - ILBM (Amiga) images
36 - photoshop files (I think I've seen docs)
37 - XBM
38 - FITS
39 - WMF (extract bitmap data on read)
40 - gzip or bzip2 compressed raw
10461f9a 41 - postscript for output

43- Transforms, interpolated multidimensional lookup tables.
44 Usefull for CMYK <-> RGB table lookup.
45
a106216b 46- advanced font layout (spacing, kerning, alignment) (Artur?)
faa9b3e7 47
bf9dd17c 48- ways to check if characters are present in a font, eg. checking if
9c5ed9a7 49 ligatures are present (done for FreeType2)
bf9dd17c 50
faa9b3e7
TC
51- font synthesis - synthesize a bold or slanted font from a normal font
52 (or even from an existing bold or slanted font)
bf9dd17c 53
faa9b3e7 54- utf8 support for text output
bf9dd17c 55 (available for freetype2)

TC
56
57- image rotation, 3 ways of doing rotation:
faa9b3e7
TC
58 - rotation by shearing, which produces makes lengths in the image larger,
59 but could be useful
a010a7d3 60 (2 of the 3 have been done)
faa9b3e7 61
9c5ed9a7
TC
62- read_multi() needs to handle other multi-image types,
63 (handles TIFF and GIF)
b921d414 64
9c5ed9a7 65- write_multi() to save other multi-image types, (handles TIFF and GIF)

67- compose channels - build a new image based on channels from several
68 images
69

72Clean up:
73- Make sure everything is doable with the OO interface
5f5fe73e 74 i_flood_fill() for example.
f1ac5027 75

AMH
76- Compile with memory debugging enabled and fix all leaks
77
78- dynaload.c is strongly tied to perl
79
a106216b 80- Add mycalloc() memory allocation wrappers.
b921d414
AMH
81
82- should we overload <=> or cmp for Imager::Color objects?
83 too many worms, leave it out
84
85- should the interlace option for reading raw images have
86 symbolic names in the OO interface?
87
f2bc9b80
TC
88- improve consistency in the interfaces, both in trying to use named
89 parameters where possible but also in using consistent names, eg.
90 (tx, ty) vs (left, top) in rubthrough() vs paste(). Do we want a (simple)
91 standard for this (suggested names)? Remember to preserve the old
92 interface where possible.
b921d414 93
b921d414 94Format specific issues:
b921d414
AMH
95- provide patches for libgif and libungif that fix their bugs
96 and give a useful extension interface. Probe for the
97 installation of the patches in Makefile.PL to let gif.c
98 know what features it can use.
99
a106216b 100- Add options for pnm writer to save in any of the p1..P6
b921d414
AMH
101 formats. Even if the input has 1 channel, write 3 and such
102 cases. Also allow ascii mode. Need to be able to write
103 pbm images which needs ties to the quantization code.
104
a106216b 105- save paletted images as paletted where that's supported. Done
f62b2d84 106 for gif/tga/bmp/tiff. Not done for png yet.
f873cb01 107
a106216b 108- read other format paletted images as paletted images. This has
f62b2d84
TC
109 been done for gif/tga/bmp/tiff formats but not for png.
110
111- read/write 16-bit/sample images as such for tiff
27d9683e 112
faa6fa9b
TC
113- read more metadata from images, esp tiff tags, EXIF format information
114 from TIFF and JPEG.

AMH
116Documentation:
117- Add to the documentation
118- Write a tutorial?
faa9b3e7
TC
119- sample code and Imager/Samples.pod describing them
120- Imager/Cookbook.pod
b921d414
AMH
121- Write a guide to installing the helper libraries
122- Go through the entire project and add comments in pod
123 so doco.perl can be used to read them.
faa6fa9b 124- see the IRC log in design/doclayout.txt
