*** TODO ***
+PRE-0.44:
+- set i_format for every file type on read and test for it:
+ - bmp - done
+ - jpeg - done
+ - tiff
+ - tga
+ - rgb
+ - png - done
+ - gif
+ - pnm
+- check each file reader for possible integer overflows
+ - bmp
+ - tiff
+ - tga
+ - rgb
+ - png
+ - gif
+ - pnm
+- check bmp code uses image data offset correctly - done
+- check quant code for integer overflows
+- check for old URLs (umich and imager.perl.org/~addi/...)
Iolayer:
- Add scalar/mmap to iolayer
- Add close() code to iolayer for fakeseek sources.
- Merge callback interface into iolayer
-- Add iolayer reading/writing for gif
- and raw
- Implment the maxread threshold (Indicates how much can
be read from a source before it stops reading from its
interface design that takes these factors into account.
- define common i_* tags for specifying attribute common among images
like spatial resolution (implement for other image types, especially
- TIFF)
+ TIFF) (Spatial resolution is supported for all types that support
+ it - are there any other common properties we can add?)
+- implement the i_incomplete tag for other formats
New Features:
- Add mng support, pcx and aalib support.
+ - Windows icon files (.ico)
+ - ILBM (Amiga) images
+ - photoshop files (I think I've seen docs)
+ - XBM
+ - FITS
+ - WMF (extract bitmap data on read)
+ - gzip or bzip2 compressed raw
+ - postscript for output
+ - PAM file support (man pam in recent PNM tools)
- Transforms, interpolated multidimensional lookup tables.
Usefull for CMYK <-> RGB table lookup.
-- Finish antialiased filled polygon function.
-
- advanced font layout (spacing, kerning, alignment) (Artur?)
- ways to check if characters are present in a font, eg. checking if
- ligatures are present
+ ligatures are present (done for FreeType2)
- font synthesis - synthesize a bold or slanted font from a normal font
(or even from an existing bold or slanted font)
- utf8 support for text output
- (available for freetype2)
+ (available for FT1, freetype2, should be easy for Win32)
+
+- easy interfaces for text output:
+ - align text around point, including:
+ - left, center, right horizontal alignment
+ - top, center, baseline, bottom alignment
+ - choose whether to base alignment upon character cells or font
+ metrics to avoid spacing problems between lines
+ - fill a box from text, with newline handling
+ - an option to just return the information that would be used to
+ output the text, so it can be used for sizing calculations
+ - how much text fit in the box/how much space is left in the box
+ - fill a box with rich text (size and font changes)
+ - as above
+ - wrapping around boxes/images
+ - pod2Imager :)
+
+- tools to get more information about fonts/characters:
+ - name of font "Arial Bold Italic" vs "arialbi.ttf"
+ - ABC widths for characters (currently the only way to get the C width
+ for a character is to get the width with a following space and without
+ and then compare)
+ - character names
+
+- encodings for text output (maybe using the Encode module to work
+ between encodings)
- image rotation, 3 ways of doing rotation:
- rotation by shearing, which produces makes lengths in the image larger,
but could be useful
(2 of the 3 have been done)
-- read_multi() needs to handle other multi-image types, such as TIFF
- (probably the most common)
+- read_multi() needs to handle other multi-image types,
+ (handles TIFF and GIF)
-- write_multi() to save other multi-image types, especially TIFF
+- write_multi() to save other multi-image types, (handles TIFF and GIF)
+ - pnm binary formats support multiple images per file
- compose channels - build a new image based on channels from several
images
-- filled polygons
-
- arc outlines
+- complex lines/curves:
+ - thick lines:
+ - dotted/dashed lines
+ - doubled lines?
+ - end-point controls (butt-end, square-end, round-end, pointy, arrows)
+ - brush-lines (as with the Gimp, or Photoshop)
+ - more complex with multiple strokes and various randomness as with
+ Fractal Design Painter (or later versions of Corel Photo Paint)
+ - complex line shapes:
+ - lines
+ - general curves (cubic or bezier, whichever is more general)
+ - easy access to general curves:
+ - points to make a nice curve from
+ - various circular curves (centre, radii, start/end angles,
+ direction)
+ - Complex thick lines are probably more useful than brush-lines for
+ the things I expect Imager to be used for.
+ - http://www.develop-help.com/imager/strokes.png (.jpg for smaller version)
+
+- have Imager::Color{::Float}? use Graphics::ColorNames if present.
+
Clean up:
- Make sure everything is doable with the OO interface
i_flood_fill() for example.
+ - include low-level functions like gsamp() and so on
- Compile with memory debugging enabled and fix all leaks
-- dynaload.c is strongly tied to perl
-
- Add mycalloc() memory allocation wrappers.
- should we overload <=> or cmp for Imager::Color objects?
standard for this (suggested names)? Remember to preserve the old
interface where possible.
+- try to clean up the inconsistencies between font types:
+ - utf8 (even if we just treat characters over 0xFF as missing for T1)
+ (done for FT2, FT1, T1)
+ - transformations (done for FT2)
+ - has_char() method (done for FT2, FT1, T1)
+
Format specific issues:
- provide patches for libgif and libungif that fix their bugs
and give a useful extension interface. Probe for the
- read/write 16-bit/sample images as such for tiff
+- read more metadata from images, esp tiff tags, EXIF format information
+ from TIFF and JPEG.
+
+- handle 16-bit/sample pgm/ppm files
+
Documentation:
- Add to the documentation
- Write a tutorial?
- sample code and Imager/Samples.pod describing them
- Imager/Cookbook.pod
-- modify the .pm files to put pod describing a function close to the
- function
- Write a guide to installing the helper libraries
- Go through the entire project and add comments in pod
so doco.perl can be used to read them.
+- see the IRC log in design/doclayout.txt
+- method index?
+- concept index?
+
+Build/configure:
+- use prompt() (from ExtUtils::MakeMaker) for questions in Makefile.PL
+- use the library's mechanism's to find the library if needed, for
+ example, freetype-config for FT2
+- the freetype2 library is built as "freetype.lib" on Win32 and needs
+ to be renamed to be found by the configuration process and included
+ with -lfreetype. Try to work around that.
+- freetype2 and freetype1 tend to be installed in /usr/include/freetype2
+ and /usr/include/freetype directories, or similarly named (somedir/freetype
+ for example), instead of putting these directly into the search path
+ search for the freetype{2}?/someheader and then add the subdirectory if
+ we find the file in that directory.
+- switch to Test::More
