5 - Add scalar/mmap to iolayer
6 - Add close() code to iolayer for fakeseek sources.
7 - Merge callback interface into iolayer
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.
15 Enhanched internal structure:
17 MultiImage & 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
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
28 TIFF) (Spatial resolution is supported for all types that support
29 it - are there any other common properties we can add?)
30 - implement the i_incomplete tag for other formats
33 - Add mng support, pcx and aalib support.
34 - Windows icon files (.ico)
36 - photoshop files (I think I've seen docs)
39 - WMF (extract bitmap data on read)
40 - gzip or bzip2 compressed raw
41 - postscript for output
43 - Transforms, interpolated multidimensional lookup tables.
44 Usefull for CMYK <-> RGB table lookup.
46 - advanced font layout (spacing, kerning, alignment) (Artur?)
48 - ways to check if characters are present in a font, eg. checking if
49 ligatures are present (done for FreeType2)
51 - font synthesis - synthesize a bold or slanted font from a normal font
52 (or even from an existing bold or slanted font)
54 - utf8 support for text output
55 (available for freetype2, should be easy for Win32, may need to fiddle
58 - easy interfaces for text output:
59 - align text around point, including:
60 - left, center, right horizontal alignment
61 - top, center, baseline, bottom alignment
62 - choose whether to base alignment upon character cells or font
63 metrics to avoid spacing problems between lines
64 - fill a box from text, with newline handling
65 - an option to just return the information that would be used to
66 output the text, so it can be used for sizing calculations
67 - how much text fit in the box/how much space is left in the box
68 - fill a box with rich text (size and font changes)
70 - wrapping around boxes/images
73 - tools to get more information about fonts/characters:
74 - name of font "Arial Bold Italic" vs "arialbi.ttf"
75 - ABC widths for characters (currently the only way to get the C width
76 for a character is to get the width with a following space and without
80 - encodings for text output (maybe using the Encode module to work
83 - image rotation, 3 ways of doing rotation:
84 - rotation by shearing, which produces makes lengths in the image larger,
86 (2 of the 3 have been done)
88 - read_multi() needs to handle other multi-image types,
89 (handles TIFF and GIF)
91 - write_multi() to save other multi-image types, (handles TIFF and GIF)
93 - compose channels - build a new image based on channels from several
99 - Make sure everything is doable with the OO interface
100 i_flood_fill() for example.
102 - Compile with memory debugging enabled and fix all leaks
104 - dynaload.c is strongly tied to perl
106 - Add mycalloc() memory allocation wrappers.
108 - should we overload <=> or cmp for Imager::Color objects?
109 too many worms, leave it out
111 - should the interlace option for reading raw images have
112 symbolic names in the OO interface?
114 - improve consistency in the interfaces, both in trying to use named
115 parameters where possible but also in using consistent names, eg.
116 (tx, ty) vs (left, top) in rubthrough() vs paste(). Do we want a (simple)
117 standard for this (suggested names)? Remember to preserve the old
118 interface where possible.
120 - try to clean up the inconsistencies between font types:
121 - utf8 (even if we just treat characters over 0xFF as missing for T1)
125 Format specific issues:
126 - provide patches for libgif and libungif that fix their bugs
127 and give a useful extension interface. Probe for the
128 installation of the patches in Makefile.PL to let gif.c
129 know what features it can use.
131 - Add options for pnm writer to save in any of the p1..P6
132 formats. Even if the input has 1 channel, write 3 and such
133 cases. Also allow ascii mode. Need to be able to write
134 pbm images which needs ties to the quantization code.
136 - save paletted images as paletted where that's supported. Done
137 for gif/tga/bmp/tiff. Not done for png yet.
139 - read other format paletted images as paletted images. This has
140 been done for gif/tga/bmp/tiff formats but not for png.
142 - read/write 16-bit/sample images as such for tiff
144 - read more metadata from images, esp tiff tags, EXIF format information
148 - Add to the documentation
150 - sample code and Imager/Samples.pod describing them
151 - Imager/Cookbook.pod
152 - Write a guide to installing the helper libraries
153 - Go through the entire project and add comments in pod
154 so doco.perl can be used to read them.
