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- Add iolayer reading/writing for gif
9- and raw
10- Implment the maxread threshold (Indicates how much can
11 be read from a source before it stops reading from its
12 underlying source. For making sure only the relevant
13 data is read from a socket for example.

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

27- define common i_* tags for specifying attribute common among images
28 like spatial resolution (implement for other image types, especially
29 TIFF)

31New Features:
a106216b 32- Add mng support, pcx and aalib support.

34- Transforms, interpolated multidimensional lookup tables.
35 Usefull for CMYK <-> RGB table lookup.
36
37- Finish antialiased filled polygon function.
38
a106216b 39- advanced font layout (spacing, kerning, alignment) (Artur?)
faa9b3e7 40

TC
41- ways to check if characters are present in a font, eg. checking if
42 ligatures are present
43

TC
44- font synthesis - synthesize a bold or slanted font from a normal font
45 (or even from an existing bold or slanted font)
bf9dd17c 46
faa9b3e7 47- utf8 support for text output
bf9dd17c 48 (available for freetype2)

50- image rotation, 3 ways of doing rotation:
faa9b3e7
TC
51 - rotation by shearing, which produces makes lengths in the image larger,
52 but could be useful
a010a7d3 53 (2 of the 3 have been done)

54
55- read_multi() needs to handle other multi-image types, such as TIFF
56 (probably the most common)
b921d414 57
362e7486
TC
58- compose channels - build a new image based on channels from several
59 images

61- filled polygons
62
63- arc outlines

65Clean up:
66- Make sure everything is doable with the OO interface
5f5fe73e 67 i_flood_fill() for example.

AMH
69- Compile with memory debugging enabled and fix all leaks
70
71- dynaload.c is strongly tied to perl
72
a106216b 73- Add mycalloc() memory allocation wrappers.
b921d414
AMH
74
75- should we overload <=> or cmp for Imager::Color objects?
76 too many worms, leave it out
77
78- should the interlace option for reading raw images have
79 symbolic names in the OO interface?
80
f2bc9b80
TC
81- improve consistency in the interfaces, both in trying to use named
82 parameters where possible but also in using consistent names, eg.
83 (tx, ty) vs (left, top) in rubthrough() vs paste(). Do we want a (simple)
84 standard for this (suggested names)? Remember to preserve the old
85 interface where possible.
b921d414 86
b921d414 87Format specific issues:
b921d414
AMH
88- provide patches for libgif and libungif that fix their bugs
89 and give a useful extension interface. Probe for the
90 installation of the patches in Makefile.PL to let gif.c
91 know what features it can use.
92
a106216b 93- Add options for pnm writer to save in any of the p1..P6
b921d414
AMH
94 formats. Even if the input has 1 channel, write 3 and such
95 cases. Also allow ascii mode. Need to be able to write
96 pbm images which needs ties to the quantization code.
97
a106216b
AMH
98- save paletted images as paletted where that's supported. Done
99 for gif/tga. Not done for png/tiff yet.
f873cb01 100
a106216b
AMH
101- read other format paletted images as paletted images. This has
102 been done for gif/tga formats but not for tiff/png.

104Documentation:
105- Add to the documentation
106- Write a tutorial?
faa9b3e7
TC
107- sample code and Imager/Samples.pod describing them
108- Imager/Cookbook.pod
109- modify the .pm files to put pod describing a function close to the
110 function
b921d414
AMH
111- Write a guide to installing the helper libraries
112- Go through the entire project and add comments in pod
113 so doco.perl can be used to read them.
