*** TODO ***
+Release Plans (subject to change)
+-------------
+
+brown-bag bugs may add intermediate releases. The dates are goals,
+not commitments.
+
+0.45: (march 2005?)
+- audit pnm.c (done)
+- audit tga.c (done)
+- audit rgb.c and add tests
+- add META.yml (bypass EU::MM's limited mechanism) (done)
+- implement i_incomplete for bmp files
+- check if freetype 2 is faster/slower than freetype 1 with Imager's glyph
+ caching. If FT1 is faster, add caching as a TODO for FT2.
+- add XS for i_tags_get_string() and test it.
+- test and fix problem with fallback value for
+ Imager::Font::BBox->advance_width.
+- add sample CGI that handles an uploaded image (done)
+- examples for fountain filter in Imager::Filters
+- allow Imager::Fountain to take color descriptions (eg. blue, FF000)
+ instead of color objects for c0 and c1 (done)
+- support newer GIMP gradient files with the Name line (done)
+- provide access to right-side bearing information from the bounding box
+ function
+- capture TIFF read warnings (i_warnings tag?) (done)
+- add Imager::Cookbook with at least 5 recipes (done)
+- store floating point tags in an appropriate precision (done)
+- allow image creation to fail on malloc() failure for the image data
+ rather than aborting. The current behaviour could be a denial of
+ service attack. This has limited utility because of the way memory
+ over commitment works on Linux (done but reverted)
+- eliminate unused variable warning (especially the RETVAL ones in Imager.xs)
+ (done)
+- handle probing for libraries better (use pkg-config or I<library>-config
+ where possible (freetype2 and libpng)) (done)
+- add concept index to Imager.pm pod (done, still working it)
+- replace testimg/penguin-base.ppm with a smaller image (done)
+- add a sample CGI HTML and image generation scripts that work together,
+ with appropriate security management (done)
+
+0.46: (june 2005)
+- allow limits to be set on the size of an image read from a file. This is
+ to prevent an attacker supplying huge images that consume all of
+ memory causing a denial of service attack.
+- add Imager::Tutorial (see Tk::UserGuide for a structure)
+ don't cover installation - belongs in README or INSTALL
+ it doesn't need to cover everything - read/write/create/simple drawing
+ and simple text - other stuff belongs in the cookbook or in sample code
+- add 5 more recipes to Imager::Cookbook
+- implement gsamp()/gsampf()/plin() etc methods for those low level image
+ interfaces which don't yet have methods.
+- implement i_incomplete for png and gif files.
+- documentation audit, check:
+ - every method has at least one example, but if the method is complex
+ (like transform2, to_paletted, string() for example) it should include
+ a range of examples
+ - check each method description to ensure it's reasonably clear.
+ - check POD sections (SEE ALSO in particular)
+- rework handling of antialiasing against transparent images
+
+Speculation
+-----------
+
+Some of what's listed below has been implemented.
+
+- should i_incomplete be optional? ie. reading a short image results in
+ an error unless the user requests incomplete images.
Iolayer:
- Add scalar/mmap to iolayer
underlying source. For making sure only the relevant
data is read from a socket for example.
-
Enhanched internal structure:
MultiImage & metadata support:
- 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.
(handles TIFF and GIF)
- 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
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?
- try to clean up the inconsistencies between font types:
- utf8 (even if we just treat characters over 0xFF as missing for T1)
- - transformations
- - has_char() method
+ (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
- 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?
- 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
+- change headers to use more unique re-include protection macros
+
+Old release checklists
+----------------------
+
+0.44: (december 2004)
+- set i_format for every file type on read and test for it:
+ - bmp - done
+ - jpeg - done
+ - tiff - done
+ - tga - done
+ - rgb - no read function anyway
+ - png - done
+ - gif - done
+ - pnm - done
+ - raw - done
+- check each file reader for possible integer overflows
+ - bmp - done
+ - tiff
+ - tga
+ - rgb
+ - png
