5Iolayer:
6- Add scalar/mmap to iolayer
7- Add close() code to iolayer
8- Merge callback interface into iolayer
9- Add interface for writing to all formats but tiff
10- Add interface for reading for png (started),
11 gif (merge with cb patch), ppm and raw
12- Add new tests once all formats support io_layer
13- Implment the maxread threshold (Indicates how far
14 a library can read before it indicates that it's done).

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)

34- Transforms, interpolated multidimensional lookup tables.
35 Usefull for CMYK <-> RGB table lookup.
36
37- Finish antialiased filled polygon function.
38

TC
39- advanced font layout (spacing, kerning, alignment) (sky)
40
bf9dd17c
TC
41- ways to check if characters are present in a font, eg. checking if
42 ligatures are present
43

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)

55- read_multi() needs to handle other multi-image types, such as TIFF
56 (probably the most common)

58- compose channels - build a new image based on channels from several
59 images

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

69- Compile with memory debugging enabled and fix all leaks
70
71- dynaload.c is strongly tied to perl
72
73- Add mycalloc() and myrealloc() to the malloc() wrappers.
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

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 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
93- Add options for pnm, writer to save in any of the p1..P6
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
27d9683e 98- pcx and targa image formats
b921d414 99

100- aalib support
101
27d9683e
TC
102- save other formats as paletted for paletted where that's supported
103
104- read other format paletted images as paletted images
105
f873cb01
TC
106- have jpeg.c write 2 or 4 channel images as 1 or 3 channels respectively

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