1 List of features to be implemented (not in any particular order)
2 ----------------------------------------------------------------
4 - collaborative editing (see discussion with Erik Demaine)
5 - porting to MacOS; merge Nokia port
6 - multiple-scenario undo history
8 - collaborative: allow non-x86 endianness (for ints, for floats?)
9 - collaborative: have an initial undo item = contents of the initial
10 xoj file + attachments for bitmap, pdf, and ps backgrounds
12 - cleanup of undo history (keep track of refcounts, delete old undo)
15 - RandR / recalibration awareness? - NOT NEEDED ANYMORE?
16 (e.g. if xinput events are far away from core events, re-query geometry?)
17 or see if removing the GTK bugfix would help? -- e.g. by recalling an
18 internal gtk init function?
19 Also allow for SIGUSR1 to recalibrate (so rotate scripts could pkill
20 xournal). (cf #2944459). Recalibration probably requires talking directly
21 to X server to query input device geometry and compensate for GTK.
24 - lingering issues with synaptics touchpads? (#2872667)
25 (todo) - set device to Absolute mode at startup? (GDK doesn't expose API,
26 cf XSetDeviceMode() in /usr/include/X11/extensions/XInput.h)
27 - color picker into canvas doesn't work in GTK+ 2.16 (should disable
29 - export to PDF should see cropbox size if smaller, and map the
30 cropbox -- not the entire page -- to the page area! (2009-11-18 forum)
35 - bug: opening files with accents in name?
36 - bug: cairo-scaled-font in printing? (2009-11-18 bug tracker)
37 - bug: printf() sometimes generates stroke coordinates 1.#J -1.#J (???)
38 (filter out inf, -inf, nan, very large values when saving ???)
40 PATCHES TO INCORPORATE:

43 http://archive.ubuntu.com/ubuntu/pool/universe/x/xournal/xournal_0.4.5-3.debian.tar.gz
44 actually not necessary anymore? (ezyang 12/2/2011)
46 - tauu e-mail of 12/1/2011: 8 small patches for win32, uploaded on tracker
47 https://sourceforge.net/tracker/index.php?func=detail&aid=3447356&group_id=163434&atid=827735
49 - patch: add Alt-Up/Dn accelerators for show/hide layer. See
52 * my own patch noresize_background_v1.patch (also in xournal-working/)
54 ** patch: ortho/snap (revised Apr 13 2009)
55 xournal_ortho_snap_patch_4 (by Josef Pavlicek)
57 ** patch (Ian-Woo Kim): multicolumn mode + LASSO SELECTION
58 xournal_lasso_multipage_zoom_button_20090620.patch
60 ** autosave patch (Edward Yang) (should fix: optional only, w/ menu + cfgfile
61 entries; fix: should clean up autosave.xoj.bg* files too; config interval)
62 0001-Implement-autosave-for-documents-revised.patch (2 seconds after
63 modification, vs original 5 seconds)
64 *** NEW VERSION: #2881919 (autosave for 0.4.5, w/ some changes)
65 NB: last modif should be triggered by prepare_new_undo() and undo/redo?
66 *** NEW VERSION: with threading, by Man, e-mail 12/10/2009 10:51pm
68 ** insert images patch (Victor Saase) #2890925
69 ** as improved by Simon Guest April 14 2010
70 ** modified rev2 May 14, 2010: xournal-0.4.5-sjg-image-rev2.patch.gz
73 ** customize paper ruling (Gautam Iyer e-mail Nov 30 2009 / SF tracker)
75 ** cairo export to PNG (Man = Paulo Neves, e-mail Feb 3 '10, saved as
76 cairo-png-rendering.diff.txt (refactor printing of page to cairo surface
77 with the gtk-print code).
80 shortcut to increase/decrease text font size by 1 point (?) - acts just
81 as if one had clicked font sel box and resized (affects sel text + cur font)
83 - make line spacing in text objects customizable: to a fixed scaling factor,
84 a fixed number of units, or the paper ruling (esp. the latter!!)
86 - page size dialog box should have a check button to keep background size
87 the same (so rescaling creates margin around bitmap or PDF background).
88 This will need an extension to the file format, to allow a page background
89 to have a different size from the page itself.
91 - option to map device named "touch" to hand tool? (like "Eraser tip")
94 - roadmap towards SVG support: see 1/25/2010 Mark Edgington email & reply
95 (1) export to SVG (using pages and groups for pages and layers;
96 use comment tags to make export nonlossy;
97 (2) import from this subset of SVG;
98 (3) add SVG to the file-open and save formats
100 - roadmap towards PDF encapsulation: see 1/29/2010 forum posts
101 When exporting to PDF, don't just append our annotations as PDF code but
102 also include the .xoj file within the pdf, and ensure the initial pdf is
103 well-delimited from the rest. When opening a PDF that includes such
104 markings, discard the annotation part of the PDF and open the embedded xoj
105 instead. Later, offer such PDF as a file-open and save format (even when
106 there's no PDF background being annotated!!).
108 *** should have Open, Save, Save As manipulate at least 3 formats:
110 - PDF with embedded xoj file in an object (opens with annot. in PDF viewer,
111 with background only + separate xoj in xournal)
113 additionally, should have "print to": printer, PDF, SVG, bitmap.
115 - allow djvu and other backgrounds (but then can't export to PDF)
117 - PDF bg memory usage throttling / delete oldest pdf backgrounds
118 - replace ttsubset by something more modern? (eg. from cairo ?)
119 - auto-hide patch from ~/prog/src/xournal-autohide/ ?
120 (check for cpu usage; handle BOTH edges
121 and only (un)hide stuff at the correct edge!)
122 ** UI update (Bob McElrath) -- eliminating status bar, compact layout,
123 "compact interface" by default; themes, with line in config file
124 to load pixmaps from pixmaps/$THEME/ (see Jan 9, 2009 emails)
125 - horizontal mode instead of dual-view / multicolumn ?
126 ** "new page before/after" on a PDF bg page should ask: same page, other page of
127 PDF file, default paper
128 ** should also have in Journal -> Paper style the option "Pdf page ..."
129 which then lets us change the page number.
130 - new recognizer icon (andruk on patches tracker)
131 - recognizer: if variable-width, associate average width
132 - recognizer should snap to existing recognized geometric shapes
133 - patch to find text in PDF (dmg = Daniel German, Nov 13 2009)
135 - search through text (xoj and PDF background) (with highlight? forwd/backwd)
136 (see evince). Also: ability to select rectangle on PDF bg and copy-paste
137 as bitmap or as text.
139 - improve recognizer: two passes for polygons (low tolerance, then higher)
140 to better detect elongated rectangles? (if low tolerance recognizer
141 doesn't get a rectangle, then use higher tolerance for everything else,
142 since otherwise there's too much risk of splitting a segment into 2)
143 - snap-to-grid (also for ruler & recognizer vertices)
144 and maybe also snap-to-vertices (option for ruler and recognizer)?
145 - config option: config save current tool options instead of default ones
147 - bug in truetype subset generation w/ Adobe 9, see if gtk-print any better?
149 - drag-and-drop, copy-paste text & images directly into xournal
150 - proximity detection: eraser proximity switches mapping?
151 proximity out removes cursor until next motionnotify?
154 - render page to bitmap: for export, preview, and copy-paste
155 (render using libart, see how gnomecanvas does it?)
156 NO: render using Cairo !!! then can switch to GtkPrint as well.
157 (copy-paste: config option to render only current layer or all below?)
158 - cut-and-paste of selection into other apps (as bitmap; as SVG?)
160 - navigation sidebar with bitmap page previews
161 - bitmap preview for document icon in desktop environments?
162 - "organizer" side panel (hierarchy of notes), cf. gjots
163 - maintain e-library: table of md5sums of pdfs with associations
164 to the corresponding xoj's absolute paths (cf. forum topic
165 "Use MD5..." of Dec 2009)
167 - see iRex code for generic viewer + PDF plugin including caching,
168 throttling etc. (Marcel Hendrickx email of Sep 11 '09)
170 - allow toolbar to go vertical
171 - toolbar buttons should react to button 2/3 click to modify settings
174 - paste text directly into xournal, from xournal?
175 (instead of starting a text item and pasting into/from it)
176 - insert links (to URLs; within document/to other xoj? hand mode navigates)
177 - a command + keyboard shortcut to switch mappings (1<->2, 1<->3, 2<->3)
178 (A. Rechnitzer Sept 11, 2007)
179 - modify encoding of TrueType font subsets or provide cmap so pdf text
182 - smoothing of strokes (for users without tablets / with deficient drivers)
184 - add config option to limit total memory usage for PDF bitmaps
185 - ability to select entire page for copy-paste (as bitmap / reorder xournal)
186 - copy/paste of an entire page (beware if PDF bg is not compatible!)
187 - rewrite printing using GtkPrint + Cairo as GnomePrint replacement
188 (keep GnomePrint option for compatibility with GTK+ <2.10)
189 - insert images (screen capture or from file or from clipboard),
190 not as full-page backgrounds (new ITEM type)
192 - convert to/from Jarnal format; to/from MS Journal format???
193 - export as SVG, as bitmap (use Cairo for this)
194 - improved PDF viewer features (search text, hyperlink, page borders...)
195 (using full poppler api ?)
196 - search text: among PDF background (using poppler); among text annotations
198 - use system paper size as default (/etc/papersize)
199 - sticky notes (anchor visually text box to a bg location)
200 - use relative paths for bg documents (e.g. annotated PDF)
201 - flush display queue when drawing over a slow X server?
202 - more paper customization (in particular, 1/2 inch graph paper)
203 (2 custom papers with settings in config file?
204 a folder with blank PDF or xoj papers and quick-access?)
205 (also: engineering paper; isometric paper -- Dan Ott Sep 4 '09)
206 - option to map a button to a context menu (incl. tool selection, ...)
207 - option to map a button to "undo"
208 - xournal_page-shadow.diff (Martin Kiefel Feb 5 2007)
209 - xoj2pdf on command line
210 - 'insert blank page after' command (more useful in PDF annot !)
211 - load images as bg if given on command-line (as with PDF on commandline)
212 - lasso selection tool (see shoffsta patch)
213 (http://shoffsta.afraid.org/Projects/Xournal/)
214 - flatten (incl undo/redo...) - enabled only if nlayers>1
215 - color chooser (papercolor, pen color); have default colors and a history
216 appear as palette in there!
217 - printing: print-options, save printer settings (throughout a session,
218 and on disk) (maybe a separate config file .xournal/gnome-print-settings)
220 - option for highlighter to be always at bottom of its layer
221 - more pen/highlighter shapes (chisel)
222 - slanted tip pens (calligraphy)
223 - toolbar buttons to access custom preset tools (e.g. text or pen with settings)
224 - text boxes with opaque background
225 - recalibration upon screen resize / compensation for miscalibration
226 (use ConfigureNotify event and XInput? cf "Bugs" tracker 08/2007)
227 - find a better behavior for vertical space tool across page boundaries ?
228 config options? 1) when there's not enough space at bottom of page:
230 - move stuff to next page
231 - move stuff to a new page
232 2) when moving to another page:
234 - move only what doesn't fit (??? looks hard)
235 option for vert space tool to also move the background??
236 (PDF: cut-and-crop by running PDF code twice with 2 different clipboxes?)
237 - option to save all annotated files within the .xoj
238 - non-antialiased version for handhelds
239 - customize autogenerated save file names
240 - layer dialog box to set visibility status of each layer regardless of
241 which layer is being edited
242 - option to link layer creation and visibility status for all pages
243 (Eric Borghs 04/15/08)
244 - display corruption on scroll down when bottom of window is obscured??
245 (probably a gnomecanvas or X bug -- expose event generated for wrong
246 region, or not processed?)
247 - autosave at a regular interval in a given location
248 - keep only a few pages of a PDF file in memory at any given time; generate
249 pages by parsing pdf info rather than generating bitmaps for all of them.
250 - win32 port (Matteo Abrate)
251 - snap-to-grid tool? (Matteo Abrate)
252 - EPOS 7/24/07: Thumbnails pane
253 - EPOS: Connect to EPOS api which sends A4 mapped points
254 - EPOS: Cut and Paste into OpenOffice applications and the GIMP (as bitmap??)
255 - EPOS: Export pages to pictures in the Jpg and Png formats.
256 - EPOS: Rotate Ink in custom angle.
257 - handwriting recognition???? (cellwriter?) unlikely. we don't have grids
258 see galileon comment on 2008-07-29 to tracker #1925309: word recognizer
259 - handwritten stroke search in document (see cellwriter?)
260 (correlate inertia-normalized strokes in lift to unit cotangent bundle?)
261 - option: export to PDF with incremental pages for successive layers
262 (for presentations) (Daniel Brugarth 8/18/07)
263 - Samuel Hoffstaetter: lasso, gettext localization, sidebar thumbnails, ...
264 - YoYo Siska patch for desktop mode ??
265 - Vivek Ayer: rotate paper wrt screen (for environments where display
266 rotation doesn't work): gnome_canvas_item_affine_relative(canvas->root, ...)
267 would rotate all but text items (still need to modify scroll bbox, and
268 adjust event coordinates by inverse rotation).
269 - rotate PDF background pages (individually wrt each other, see #2099935)
270 - switch to libglade, and allow customization of key shortcuts (accels)
272 - command to copy a selected shape to a keybinding that will paste it
273 (so one can define symbols to insert into typed notes) (e.g. "be able
274 to bind Ctrl-B to draw a \beta" for class notes). (shape, binding) sets are
275 local to one session (different for different classes; but save them into
276 the xoj file maybe ?) [Felix Giannelia 09/29/2009]
