List of features to be implemented (not in any particular order) ---------------------------------------------------------------- - collaborative editing (see discussion with Erik Demaine) - porting to MacOS; merge Nokia port - multiple-scenario undo history - collaborative: allow non-x86 endianness (for ints, for floats?) - collaborative: have an initial undo item = contents of the initial xoj file + attachments for bitmap, pdf, and ps backgrounds - cleanup of undo history (keep track of refcounts, delete old undo) save-and-clear-undo ? - RandR / recalibration awareness? (e.g. if xinput events are far away from core events, re-query geometry?) or see if removing the GTK bugfix would help? -- e.g. by recalling an internal gtk init function? BUGS: ** lingering issues with synaptics touchpads? (#2872667) (todo) - set device to Absolute mode at startup? (GDK doesn't expose API, cf XSetDeviceMode() in /usr/include/X11/extensions/XInput.h) ** color picker into canvas doesn't work in GTK+ 2.16 (should disable xinput first?) ** export to PDF should see cropbox size if smaller, and map the cropbox -- not the entire page -- to the page area! (2009-11-18 forum) WIN32: - test further - write an installer - bug: opening files with accents in name? - bug: cairo-scaled-font in printing? (2009-11-18 bug tracker) PATCHES TO INCORPORATE: ** patch: ortho/snap (revised Apr 13 2009) xournal_ortho_snap_patch_4 (by Josef Pavlicek) ** patch (Ian-Woo Kim): multicolumn mode + LASSO SELECTION xournal_lasso_multipage_zoom_button_20090620.patch ** autosave patch (Edward Yang) (should fix: optional only, w/ menu + cfgfile entries; fix: should clean up autosave.xoj.bg* files too; config interval) 0001-Implement-autosave-for-documents-revised.patch (2 seconds after modification, vs original 5 seconds) *** NEW VERSION: #2881919 (autosave for 0.4.5, w/ some changes) NB: last modif should be triggered by prepare_new_undo() and undo/redo? *** NEW VERSION: with threading, by Man, e-mail 12/10/2009 10:51pm ** insert images patch (Victor Saase) #2890925 ** customize paper ruling (Gautam Iyer e-mail Nov 30 2009 / SF tracker) - option to map device named "touch" to hand tool? (like "Eraser tip") - make line spacing in text objects customizable: to a fixed scaling factor, a fixed number of units, or the paper ruling (esp. the latter!!) - PDF bg memory usage throttling / delete oldest pdf backgrounds - replace ttsubset by something more modern? (eg. from cairo ?) - auto-hide patch from ~/prog/src/xournal-autohide/ ? (check for cpu usage; handle BOTH edges and only (un)hide stuff at the correct edge!) ** UI update (Bob McElrath) -- eliminating status bar, compact layout, "compact interface" by default; themes, with line in config file to load pixmaps from pixmaps/$THEME/ (see Jan 9, 2009 emails) - horizontal mode instead of dual-view / multicolumn ? ** "new page before/after" on a PDF bg page should ask: same page, other page of PDF file, default paper - new recognizer icon (andruk on patches tracker) - recognizer: if variable-width, associate average width - recognizer should snap to existing recognized geometric shapes - patch to find text in PDF (dmg = Daniel German, Nov 13 2009) - improve recognizer: two passes for polygons (low tolerance, then higher) to better detect elongated rectangles? (if low tolerance recognizer doesn't get a rectangle, then use higher tolerance for everything else, since otherwise there's too much risk of splitting a segment into 2) - snap-to-grid (also for ruler & recognizer vertices) and maybe also snap-to-vertices (option for ruler and recognizer)? - config option: config save current tool options instead of default ones - bug in truetype subset generation w/ Adobe 9, see if gtk-print any better? - drag-and-drop, copy-paste text & images directly into xournal - proximity detection: eraser proximity switches mapping? proximity out removes cursor until next motionnotify? - render page to bitmap: for export, preview, and copy-paste (render using libart, see how gnomecanvas does it?) NO: render using Cairo !!! then can switch to GtkPrint as well. (copy-paste: config option to render only current layer or all below?) - cut-and-paste of selection into other apps (as bitmap; as SVG?) - navigation sidebar with bitmap page previews - bitmap preview for document icon in desktop environments? - "organizer" side panel (hierarchy of notes), cf. gjots - maintain e-library: table of md5sums of pdfs with associations to the corresponding xoj's absolute paths (cf. forum topic "Use MD5..." of Dec 2009) - see iRex code for generic viewer + PDF plugin including caching, throttling etc. (Marcel Hendrickx email of Sep 11 '09) - allow toolbar to go vertical - toolbar buttons should react to button 2/3 click to modify settings for that tool!! - paste text directly into xournal, from xournal? (instead of starting a text item and pasting into/from it) - insert links (to URLs; within document/to other xoj? hand mode navigates) - a command + keyboard shortcut to switch mappings (1<->2, 1<->3, 2<->3) (A. Rechnitzer Sept 11, 2007) - modify encoding of TrueType font subsets or provide cmap so pdf text can be extracted - smoothing of strokes (for users without tablets / with deficient drivers) - lasso tool - add config option to limit total memory usage for PDF bitmaps - ability to select entire page for copy-paste (as bitmap / reorder xournal) - copy/paste of an entire page (beware if PDF bg is not compatible!) - rewrite printing using GtkPrint + Cairo as GnomePrint replacement (keep GnomePrint option for compatibility with GTK+ <2.10) - insert images (screen capture or from file or from clipboard), not as full-page backgrounds (new ITEM type) - convert to/from Jarnal format; to/from MS Journal format??? - export as SVG, as bitmap (use Cairo for this) - improved PDF viewer features (search text, hyperlink, page borders...) (using full poppler api ?) - search text: among PDF background (using poppler); among text annotations - use system paper size as default (/etc/papersize) - sticky notes (anchor visually text box to a bg location) - use relative paths for bg documents (e.g. annotated PDF) - flush display queue when drawing over a slow X server? - more paper customization (in particular, 1/2 inch graph paper) (2 custom papers with settings in config file? a folder with blank PDF or xoj papers and quick-access?) (also: engineering paper; isometric paper -- Dan Ott Sep 4 '09) - option to map a button to a context menu (incl. tool selection, ...) - option to map a button to "undo" - xournal_page-shadow.diff (Martin Kiefel Feb 5 2007) - xoj2pdf on command line - 'insert blank page after' command (more useful in PDF annot !) - load images as bg if given on command-line (as with PDF on commandline) - lasso selection tool (see shoffsta patch) (http://shoffsta.afraid.org/Projects/Xournal/) - flatten (incl undo/redo...) - enabled only if nlayers>1 - color chooser (papercolor, pen color); have default colors and a history appear as palette in there! - printing: print-options, save printer settings (throughout a session, and on disk) (maybe a separate config file .xournal/gnome-print-settings) - help index - option for highlighter to be always at bottom of its layer - more pen/highlighter shapes (chisel) - slanted tip pens (calligraphy) - toolbar buttons to access custom preset tools (e.g. text or pen with settings) - text boxes with opaque background - recalibration upon screen resize / compensation for miscalibration (use ConfigureNotify event and XInput? cf "Bugs" tracker 08/2007) - find a better behavior for vertical space tool across page boundaries ? config options? 1) when there's not enough space at bottom of page: - resize the page - move stuff to next page - move stuff to a new page 2) when moving to another page: - move everything - move only what doesn't fit (??? looks hard) option for vert space tool to also move the background?? (PDF: cut-and-crop by running PDF code twice with 2 different clipboxes?) - option to save all annotated files within the .xoj - non-antialiased version for handhelds - customize autogenerated save file names - layer dialog box to set visibility status of each layer regardless of which layer is being edited - option to link layer creation and visibility status for all pages (Eric Borghs 04/15/08) - display corruption on scroll down when bottom of window is obscured?? (probably a gnomecanvas or X bug -- expose event generated for wrong region, or not processed?) - autosave at a regular interval in a given location - keep only a few pages of a PDF file in memory at any given time; generate pages by parsing pdf info rather than generating bitmaps for all of them. - win32 port (Matteo Abrate) - snap-to-grid tool? (Matteo Abrate) - EPOS 7/24/07: Thumbnails pane - EPOS: Connect to EPOS api which sends A4 mapped points - EPOS: Cut and Paste into OpenOffice applications and the GIMP (as bitmap??) - EPOS: Export pages to pictures in the Jpg and Png formats. - EPOS: Rotate Ink in custom angle. - handwriting recognition???? (cellwriter?) unlikely. we don't have grids see galileon comment on 2008-07-29 to tracker #1925309: word recognizer - handwritten stroke search in document (see cellwriter?) (correlate inertia-normalized strokes in lift to unit cotangent bundle?) - option: export to PDF with incremental pages for successive layers (for presentations) (Daniel Brugarth 8/18/07) - Samuel Hoffstaetter: lasso, gettext localization, sidebar thumbnails, ... - YoYo Siska patch for desktop mode ?? - Vivek Ayer: rotate paper wrt screen (for environments where display rotation doesn't work): gnome_canvas_item_affine_relative(canvas->root, ...) would rotate all but text items (still need to modify scroll bbox, and adjust event coordinates by inverse rotation). - rotate PDF background pages (individually wrt each other, see #2099935) - switch to libglade, and allow customization of key shortcuts (accels) - command to copy a selected shape to a keybinding that will paste it (so one can define symbols to insert into typed notes) (e.g. "be able to bind Ctrl-B to draw a \beta" for class notes). (shape, binding) sets are local to one session (different for different classes; but save them into the xoj file maybe ?) [Felix Giannelia 09/29/2009]
