Alt-A / select files i same directory, can be repeated. + - rename select by prefix to select by adjacent name. + - increase search range for adjacent name to 10000. + - change meta-mask to mod1-mask, as gtk+ has silently changed the meaning of meta + over the years (so much for api stability...). + - newer perl versions somehow manage to leak the prefetch file handle somehow, + try tro work aorund. + - implement (undocumented) filename_display_name hook in Gt2k::CV::Schnauer. + - use symbolic names for entry indices in Schnauzer, for sanity, as the design + is now stable enough. + -

very simple "better than nothing" jpeg cmyk/ycck format decoding. + - use ffprobe instead of mplayer to probe video size/type. + - switch to using AnyEvent::Fork as provider for the processpool, which ought + to save gobs of memory. + - much improved async communications with worker processes. + - batch expose events together, in an attempt to reduce the amount of + expose races in gtk+ (does not fix scrolling races). + - create #cpu + 1 worker jobs now, not 1.5 * #cpu + 1 as before. + -

only warn about pipe close failures in printdialog, do not die. + - do not try to handle filenames in unicode, instead, only + convert at display time. + - kill any media players on destroy and not in the finaliser, + as gtk+'s lazy finalisation and mplayers stubbornness to + continue running without control socket and output window + can be annoying. + - add recursive delete (lamely implemented using rm -rf). + - update progressbar after a timeout in addition to after + enough work has done to ensure it is being displayed + quickly for long jobs. + +1.51 Sun Jan 27 17:48:14 CET 2008 + -

use new experimental (but much faster) clustering feature vector + based on moments and not on a histogram. + - reimplement file movement to use IO::AIO natively, thus much faster + and lower on resources. + +1.2 Fri Mar 31 12:55:15 CEST 2006 + - fix unnecessarily redraws on partial exposes (scrolling etc). + - fixed CV_TRASHCAN support. + - "a" calls exiftran to rotate the image on-disk. + - don't run jobs on the same file in parallel. + - filenames were sometiems encoded twice when loading xvpics. + -

set window roles. + - changed xor color from 0x8080 PC to 0x8000, as the former yields + useless results on gtk 2.8. + - fix p7 thumbnail reading. + +1.1 Fri Oct 28 15:47:53 CEST 2005 + - jobs for files currently shown in a schnauzer get prioritised. + - directories visited in a session are shown darker. + - unvisited directory with .xvpics in them are shown differently. + - add Remove Thumbnails menu entry. + - allow restricting image size to something less than the screen + (ctrl-shift-m). + - fix a bug where background processes stopped processing jobs. + - primary selection support for schnauzer selections. + - documented and implemented scorlling behaviour while drag-selecting. + - implemented Select=>By Prefix. + - background loading of .xvpics (and checking for symlinks-to-dirs). + - use overlays to differentiate between directories that + are empty, have .xvpics or are symlinks-to-directories. + - better/slower expose handling (we need double-refreshes due to + probable bugs in gtk+ or X11). + - implement a dirstack (statestack) and make use of it. + - don't forget cursor position on ctrl-g and similar commands. + - implemented keep_only_thumbnailed and remove_thumbnailed. + - implemented multiple-image-window support in cv. + - do some extra random resizes on the mplayer window to get it + to notice the damned window size. + - reap fork'ed job processes to avoid ressource leaks. + - fixed GNU R clustering. + +1.0 Wed Sep 7 18:41:38 CEST 2005 + - fix alpha handling: we now compose with a checkerboard, + but exposing hidden pixel data is also supported in the code. + - use jpg instead of P7 format for thumbnails and remove p7 + write support: better quality, smaller filesize. + - evaluate _NET_FRAME_EXTENTS to get actual maximum screen size. + - better mplayer integration (resize handling, aspect handling). + - fix some bugs when a Schnauzer window was resized and got + the wrong offset. + - don't crash when trying to crop to a size of less than a pixel. + - schnauzer now has two modes: directors view or single-file view. + this changes it's behaviour on rescan and other occasions. + - reduce the amount of random dithering. + - load jpeg files ~20% faster, create jpeg thumbnails an order + of magnitude faster. + - improved bin/cv documentation. + - improve scanning performance further by usign the directory + link count and by stat'ing possible directories early. + - do file data prefetch after space or backspace and 0.3s. + - better and faster casefolding. + - use pango's ellipsise functionality and cut at the end. + - moved the R clustering algo to a separate plugin (and fix it). + -

added icon for .tif files. + - updated icons for some file-extensions. + - created a job system and create thumbnails in parallel and + in the background. + - more careful handling of filename encodings. + - use gdk_pixbuf_rotate_simple instead of our own functions. + - played with resizing logic once more. + +0.5 Mon Jul 11 05:48:13 CEST 2005 + - image window resizing now works again. + - much improved resize/move handling (still not up to xv's level). + - every schnauzer now has an associated label/info field. + - better ^D performance. + - can now play videos if mplayer is in the path (and probably is + identical to my versions and your config file is empty etc. etc. + the usual caveats about embedding mplayer...) + (http://itdp.fh-biergarten.de/mplayer-dev-eng/2004-12/txt00028.txt fixes + the resize problems). + - remove gtk20-compatibility cruft. + - added progress window for lengthy operations. + - removed entry, use popup=>Up. + - change of contact address. + - updated icons for some file-extensions. + - make cv's info label wrap as not to change horizontal window width + (doesn't work, but that's general gtk2 brokenness). + - use set_absolute_size for the schnauzer font. doesn't result in an + absolute size, but at least results in the same height everywhere. + - implemented a primitive plugin system (see Gtk2::CV::Plugin and + eg/plugin-skeleton). + - removed bin/cvc's clusteriser. + - added a new clusteriser algorithm, use Popup=>"Filename clustering..." + - set _X_CWD to current dir in bin/cv (a rather special feature...). + - further directory scanning speed improvements. + - IO::AIO use for some speedups and more concurrency. 0.3 Sun Aug 1 21:59:49 CEST 2004 - cv * now correctly loads && selects the first image again. - - changed selection behaviour to select ranges not rectangles -
