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).

16BUGS:
17
42dd04ca 18- jpeg writer doesn't handle write errors

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

31- define common i_* tags for specifying attribute common among images
32 like spatial resolution (implement for other image types, especially
33 TIFF)

36- Add mng support.

38- Transforms, interpolated multidimensional lookup tables.
39 Usefull for CMYK <-> RGB table lookup.
40
41- Finish antialiased filled polygon function.
42

TC
43- advanced font layout (spacing, kerning, alignment) (sky)
44
45- font synthesis - synthesize a bold or slanted font from a normal font
46 (or even from an existing bold or slanted font)
47- utf8 support for text output
48
49- image rotation, 3 ways of doing rotation:
faa9b3e7
TC
50 - rotation by shearing, which produces makes lengths in the image larger,
51 but could be useful
a010a7d3 52 (2 of the 3 have been done)

53
54- read_multi() needs to handle other multi-image types, such as TIFF
55 (probably the most common)

57Clean up:
58- Make sure everything is doable with the OO interface
5f5fe73e 59 i_flood_fill() for example.

61- Compile with memory debugging enabled and fix all leaks
62
63- dynaload.c is strongly tied to perl
64
65- Add mycalloc() and myrealloc() to the malloc() wrappers.
66
67- should we overload <=> or cmp for Imager::Color objects?
68 too many worms, leave it out
69
70- should the interlace option for reading raw images have
71 symbolic names in the OO interface?
72

73- improve consistency in the interfaces, both in trying to use named
74 parameters where possible but also in using consistent names, eg.
75 (tx, ty) vs (left, top) in rubthrough() vs paste(). Do we want a (simple)
76 standard for this (suggested names)? Remember to preserve the old
77 interface where possible.

b921d414 79Format specific issues:
b921d414
AMH
80- provide patches for libgif and libungif that fix their bugs
81 and give a useful extension interface. Probe for the
82 installation of the patches in Makefile.PL to let gif.c
83 know what features it can use.
84
85- Add options for pnm, writer to save in any of the p1..P6
86 formats. Even if the input has 1 channel, write 3 and such
87 cases. Also allow ascii mode. Need to be able to write
88 pbm images which needs ties to the quantization code.
89
27d9683e 90- pcx and targa image formats
b921d414 91

TC
92- aalib support
93
27d9683e
TC
94- when saving gifs handle the case where paletted images are being saved
95
96- save other formats as paletted for paletted where that's supported
97
98- read other format paletted images as paletted images
99

100- have jpeg.c write 2 or 4 channel images as 1 or 3 channels respectively

103Documentation:
104- Add to the documentation
105- Write a tutorial?
faa9b3e7
TC
106- sample code and Imager/Samples.pod describing them
107- Imager/Cookbook.pod
108- modify the .pm files to put pod describing a function close to the
109 function
b921d414
AMH
110- Write a guide to installing the helper libraries
111- Go through the entire project and add comments in pod
112 so doco.perl can be used to read them.
