194 - more documentation (and corresponding code cleanup)
196 - external C API access
198 - hooks for file reading/writing
200 - hooks for font types
206 - filter pre-processor for handling both image access methods
208 - move existing loadable filters into separate sub-directories
212 - maybe Imager::Tk::Photo
215 0.46: (September 2005)
217 - check remaining memory allocation calls for integer overflows
218 http://rt.cpan.org/NoAuth/Bug.html?id=8213
219 - check *alloc() calls
220 - check llist_push() calls
222 - fix Imager::Color warning when $ENV{HOME} isn't set from
223 _get_gimp_color() (done)
224 http://rt.cpan.org/NoAuth/Bug.html?id=13143
226 - module version numbers (done)
227 http://rt.cpan.org/NoAuth/Bug.html?id=13047
229 - allow limits to be set on the size of an image read from a file. This is
230 to prevent an attacker supplying huge images that consume all of
231 memory causing a denial of service attack. (done)
233 - implement gsamp()/gsampf()/plin() etc methods for those low level image
234 interfaces which don't yet have methods. (done)
239 - add Imager::Tutorial (see Tk::UserGuide for a structure) (done)
240 don't cover installation - belongs in README or INSTALL
241 it doesn't need to cover everything - read/write/create/simple drawing
242 and simple text - other stuff belongs in the cookbook or in sample code
244 - rename lib/Imager/Cookbook.pm to lib/Imager/Cookbook.pod (done)
246 - add 5 more recipes to Imager::Cookbook
248 - implement i_incomplete for png and gif files.
250 - documentation audit, check:
251 - every method has at least one example, but if the method is complex
252 (like transform2, to_paletted, string() for example) it should include
254 - check each method description to ensure it's reasonably clear.
255 - check POD sections (SEE ALSO in particular)
256 - multiple examples for writing GIF images.
257 - name arguments and use those names in the documentation
258 http://nntp.perl.org/group/perl.perl5.porters/102434
259 (#1521, #5608, #8231, #11429, #13058(done))
261 - have $img->read() act like ($img) = Imager->read_multi() on GIFs (done)
263 - figure out what the nearest_color filter does, and document it
265 - remove image.h dependency on t1lib.h (done)
267 - make sure dynfilt/Makefile.PL gets the same includes that
272 - rework handling of antialiasing and other transparency against
278 - anything that uses combine (fills in particular)
279 - image scaling? and matrix_transform()'s interpolation
280 http://rt.cpan.org/NoAuth/Bug.html?id=11972
284 - fill out handling of large sample (16/double per sample) images
303 Some of what's listed below has been implemented.
305 - should i_incomplete be optional? ie. reading a short image results in
306 an error unless the user requests incomplete images.
309 - Add scalar/mmap to iolayer
310 - Add close() code to iolayer for fakeseek sources.
311 - Merge callback interface into iolayer
313 - Implment the maxread threshold (Indicates how much can
314 be read from a source before it stops reading from its
315 underlying source. For making sure only the relevant
316 data is read from a socket for example.
318 Enhanched internal structure:
320 MultiImage & metadata support:
321 - Figure what interface should be between C and perl?
322 - How to store data in the C interface for tags/metadata?
323 Support tiff's madness, i.e. tags and options.
324 - Error handling, make a general i_errstr object and arrange
325 such that each image has an i_errstr object to hold its
327 - SEE design/represent.txt for proposed new structure and
328 interface design that takes these factors into account.
329 - define common i_* tags for specifying attribute common among images
330 like spatial resolution (implement for other image types, especially
331 TIFF) (Spatial resolution is supported for all types that support
332 it - are there any other common properties we can add?)
333 - implement the i_incomplete tag for other formats
336 - Add mng support, pcx and aalib support.
337 - Windows icon files (.ico) (done)
338 - ILBM (Amiga) images
339 - photoshop files (I think I've seen docs)
342 - WMF (extract bitmap data on read)
343 - gzip or bzip2 compressed raw
344 - postscript for output
345 - PAM file support (man pam in recent PNM tools)
347 - Transforms, interpolated multidimensional lookup tables.
348 Usefull for CMYK <-> RGB table lookup.
350 - advanced font layout (spacing, kerning, alignment) (Artur?)
352 - ways to check if characters are present in a font, eg. checking if
353 ligatures are present (done for FreeType2)
355 - font synthesis - synthesize a bold or slanted font from a normal font
356 (or even from an existing bold or slanted font)
358 - utf8 support for text output
359 (available for FT1, freetype2, T1, Win32)
361 - easy interfaces for text output:
362 - align text around point, including:
363 - left, center, right horizontal alignment
364 - top, center, baseline, bottom alignment
365 - choose whether to base alignment upon character cells or font
366 metrics to avoid spacing problems between lines
367 - fill a box from text, with newline handling
368 - an option to just return the information that would be used to
369 output the text, so it can be used for sizing calculations
370 - how much text fit in the box/how much space is left in the box
371 - fill a box with rich text (size and font changes)
373 - wrapping around boxes/images
376 - tools to get more information about fonts/characters:
377 - name of font "Arial Bold Italic" vs "arialbi.ttf"
378 - ABC widths for characters (currently the only way to get the C width
379 for a character is to get the width with a following space and without
383 - encodings for text output (maybe using the Encode module to work
386 - image rotation, 3 ways of doing rotation:
387 - rotation by shearing, which produces makes lengths in the image larger,
389 (2 of the 3 have been done)
391 - read_multi() needs to handle other multi-image types,
392 (handles TIFF and GIF)
394 - write_multi() to save other multi-image types, (handles TIFF and GIF)
395 - pnm binary formats support multiple images per file
397 - compose channels - build a new image based on channels from several
402 - complex lines/curves:
404 - dotted/dashed lines
406 - end-point controls (butt-end, square-end, round-end, pointy, arrows)
407 - brush-lines (as with the Gimp, or Photoshop)
408 - more complex with multiple strokes and various randomness as with
409 Fractal Design Painter (or later versions of Corel Photo Paint)
410 - complex line shapes:
412 - general curves (cubic or bezier, whichever is more general)
413 - easy access to general curves:
414 - points to make a nice curve from
415 - various circular curves (centre, radii, start/end angles,
417 - Complex thick lines are probably more useful than brush-lines for
418 the things I expect Imager to be used for.
419 - http://www.develop-help.com/imager/strokes.png (.jpg for smaller version)
421 - have Imager::Color{::Float}? use Graphics::ColorNames if present.
424 - Make sure everything is doable with the OO interface
425 i_flood_fill() for example.
426 - include low-level functions like gsamp() and so on
428 - Compile with memory debugging enabled and fix all leaks
430 - Add mycalloc() memory allocation wrappers.
432 - should we overload <=> or cmp for Imager::Color objects?
433 too many worms, leave it out
435 - should the interlace option for reading raw images have
436 symbolic names in the OO interface?
438 - improve consistency in the interfaces, both in trying to use named
439 parameters where possible but also in using consistent names, eg.
440 (tx, ty) vs (left, top) in rubthrough() vs paste(). Do we want a (simple)
441 standard for this (suggested names)? Remember to preserve the old
442 interface where possible.
444 - try to clean up the inconsistencies between font types:
445 - utf8 (even if we just treat characters over 0xFF as missing for T1)
446 (done for FT2, FT1, T1)
447 - transformations (done for FT2)
448 - has_char() method (done for FT2, FT1, T1)
450 Format specific issues:
451 - provide patches for libgif and libungif that fix their bugs
452 and give a useful extension interface. Probe for the
453 installation of the patches in Makefile.PL to let gif.c
454 know what features it can use. (no need anymore)
456 - Add options for pnm writer to save in any of the p1..P6
457 formats. Even if the input has 1 channel, write 3 and such
458 cases. Also allow ascii mode. Need to be able to write
459 pbm images which needs ties to the quantization code.
461 - save paletted images as paletted where that's supported. Done
462 for gif/tga/bmp/tiff. Not done for png yet.
464 - read other format paletted images as paletted images. This has
465 been done for gif/tga/bmp/tiff formats but not for png.
467 - read/write 16-bit/sample images as such for tiff
469 - read more metadata from images, esp tiff tags, EXIF format information
472 - handle 16-bit/sample pgm/ppm files (done)
474 - "jpeg lossless rotation" - directly manipulates the JPEG
475 representation to rotate, scale or in some limited cases, crop an
479 - Add to the documentation
481 - sample code and Imager/Samples.pod describing them
482 - Imager/Cookbook.pod
483 - Write a guide to installing the helper libraries
484 - Go through the entire project and add comments in pod
485 so doco.perl can be used to read them.
486 - see the IRC log in design/doclayout.txt
491 - use prompt() (from ExtUtils::MakeMaker) for questions in Makefile.PL
492 - use the library's mechanism's to find the library if needed, for
493 example, freetype-config for FT2
494 - the freetype2 library is built as "freetype.lib" on Win32 and needs
495 to be renamed to be found by the configuration process and included
496 with -lfreetype. Try to work around that.
497 - freetype2 and freetype1 tend to be installed in /usr/include/freetype2
498 and /usr/include/freetype directories, or similarly named (somedir/freetype
499 for example), instead of putting these directly into the search path
500 search for the freetype{2}?/someheader and then add the subdirectory if
501 we find the file in that directory.
502 - switch to Test::More
503 - change headers to use more unique re-include protection macros
505 Old release checklists
506 ----------------------
508 0.44: (december 2004)
509 - set i_format for every file type on read and test for it:
514 - rgb - no read function anyway
519 - check each file reader for possible integer overflows
527 - check bmp code uses image data offset correctly - done
528 - check quant code for integer overflows - done
529 - check for old URLs (umich and imager.perl.org/~addi/...) - done
532 - resolve fills test failure under 5.8.6/darwin
533 http://www.nntp.perl.org/group/perl.cpan.testers/202802
534 add tests to check if the same problem occurs with other ?: operators
535 - stop tga_header_verify() from spewing junk to stdout (done)
536 - fix i_setcolors_p bug (done)
539 - audit rgb.c and add tests
540 - add META.yml (bypass EU::MM's limited mechanism) (done)
541 - implement i_incomplete for bmp files
542 - check if freetype 2 is faster/slower than freetype 1 with Imager's glyph
543 caching. If FT1 is faster, add caching as a TODO for FT2.
544 - add XS for i_tags_get_string() and test it. It has an apparent problem
545 in C<< sprintf(value, "%d", entry->data); >> since data is a pointer
547 - test and fix problem with fallback value for
548 Imager::Font::BBox->advance_width. (done)
549 - check handling of string() method align parameter. (done, fixed)
550 - i_tt_bbox_inst in font.c uses variable i without ever setting it. (fixed)
551 - add sample CGI that handles an uploaded image (done)
552 - examples for fountain filter in Imager::Filters (done)
553 - allow Imager::Fountain to take color descriptions (eg. blue, FF000)
554 instead of color objects for c0 and c1 (done)
555 - support newer GIMP gradient files with the Name line (done)
556 - provide access to right-side bearing information from the bounding box
557 function (done for all drivers)
558 - capture TIFF read warnings (i_warnings tag?) (done)
559 - Imager::Matrix2d rotate method only applies offset if both x and y
560 are non-zero, it should do it if either is non-zero (done)
561 - add Imager::Cookbook with at least 5 recipes (done)
562 - store floating point tags in an appropriate precision (done)
563 - allow image creation to fail on malloc() failure for the image data
564 rather than aborting. The current behaviour could be a denial of
565 service attack. This has limited utility because of the way memory
566 over commitment works on Linux (done but reverted)
567 - eliminate unused variable warning (especially the RETVAL ones in Imager.xs)
569 - handle probing for libraries better (use pkg-config or I<library>-config
570 where possible (freetype2 and libpng)) (done)
571 - add concept index to Imager.pm pod (done, still working it)
572 - replace testimg/penguin-base.ppm with a smaller image (done)
573 - add a sample CGI HTML and image generation scripts that work together,
574 with appropriate security management (done)
