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 - image patch related:
25 - paste and selresize don't put rectangle at top
26 - need option for image mode to revert to previous tool?
27 - optimize storage of embedded images by detecting duplicates (D. German)
30 - lingering issues with synaptics touchpads? (#2872667)
31 (todo) - set device to Absolute mode at startup? (GDK doesn't expose API,
32 cf XSetDeviceMode() in /usr/include/X11/extensions/XInput.h)
33 - color picker into canvas doesn't work in GTK+ 2.16 (should disable
35 - export to PDF should see cropbox size if smaller, and map the
36 cropbox -- not the entire page -- to the page area! (2009-11-18 forum)
39 - option to have "Save Prefs" save current brushes as settings, not defaults
40 - method to map more general devices to specific tools or to Ignore
41 (e.g.: X220T ignore trackpoint; map touchscreen to Hand, eraser to Eraser)
46 - bug: opening files with accents in name?
47 - bug: cairo-scaled-font in printing? (2009-11-18 bug tracker)
48 - bug: printf() sometimes generates stroke coordinates 1.#J -1.#J (???)
49 (filter out inf, -inf, nan, very large values when saving ???)
51 PATCHES TO INCORPORATE:
53 - ezyang e-mail of 11/28/2011: patches in Ubuntu to fix PDF showing up?
54 http://archive.ubuntu.com/ubuntu/pool/universe/x/xournal/xournal_0.4.5-3.debian.tar.gz
55 actually not necessary anymore? (ezyang 12/2/2011)
57 - tauu e-mail of 12/1/2011: 8 small patches for win32, uploaded on tracker
58 https://sourceforge.net/tracker/index.php?func=detail&aid=3447356&group_id=163434&atid=827735
60 - patch: add Alt-Up/Dn accelerators for show/hide layer. See
63 * my own patch noresize_background_v1.patch (also in xournal-working/)
65 ** patch: ortho/snap (revised Apr 13 2009)
66 xournal_ortho_snap_patch_4 (by Josef Pavlicek)
68 ** patch (Ian-Woo Kim): multicolumn mode + LASSO SELECTION
69 xournal_lasso_multipage_zoom_button_20090620.patch
71 ** autosave patch (Edward Yang) (should fix: optional only, w/ menu + cfgfile
72 entries; fix: should clean up autosave.xoj.bg* files too; config interval)
73 0001-Implement-autosave-for-documents-revised.patch (2 seconds after
74 modification, vs original 5 seconds)
75 *** NEW VERSION: #2881919 (autosave for 0.4.5, w/ some changes)
76 NB: last modif should be triggered by prepare_new_undo() and undo/redo?
77 *** NEW VERSION: with threading, by Man, e-mail 12/10/2009 10:51pm
79 ** customize paper ruling (Gautam Iyer e-mail Nov 30 2009 / SF tracker)
81 ** cairo export to PNG (Man = Paulo Neves, e-mail Feb 3 '10, saved as
82 cairo-png-rendering.diff.txt (refactor printing of page to cairo surface
83 with the gtk-print code).
86 shortcut to increase/decrease text font size by 1 point (?) - acts just
87 as if one had clicked font sel box and resized (affects sel text + cur font)
89 - make line spacing in text objects customizable: to a fixed scaling factor,
90 a fixed number of units, or the paper ruling (esp. the latter!!)
92 - page size dialog box should have a check button to keep background size
93 the same (so rescaling creates margin around bitmap or PDF background).
94 This will need an extension to the file format, to allow a page background
95 to have a different size from the page itself.
97 - option to map device named "touch" to hand tool? (like "Eraser tip")
99 - roadmap towards SVG support: see 1/25/2010 Mark Edgington email & reply
100 (1) export to SVG (using pages and groups for pages and layers;
101 use comment tags to make export nonlossy;
102 (2) import from this subset of SVG;
103 (3) add SVG to the file-open and save formats
105 - roadmap towards PDF encapsulation: see 1/29/2010 forum posts
106 When exporting to PDF, don't just append our annotations as PDF code but
107 also include the .xoj file within the pdf, and ensure the initial pdf is
108 well-delimited from the rest. When opening a PDF that includes such
109 markings, discard the annotation part of the PDF and open the embedded xoj
110 instead. Later, offer such PDF as a file-open and save format (even when
111 there's no PDF background being annotated!!).
113 *** should have Open, Save, Save As manipulate at least 3 formats:
115 - PDF with embedded xoj file in an object (opens with annot. in PDF viewer,
116 with background only + separate xoj in xournal)
118 additionally, should have "print to": printer, PDF, SVG, bitmap.
120 - allow djvu and other backgrounds (but then can't export to PDF)
122 - PDF bg memory usage throttling / delete oldest pdf backgrounds
123 - replace ttsubset by something more modern? (eg. from cairo ?)
124 - auto-hide patch from ~/prog/src/xournal-autohide/ ?
125 (check for cpu usage; handle BOTH edges
126 and only (un)hide stuff at the correct edge!)
127 ** UI update (Bob McElrath) -- eliminating status bar, compact layout,
128 "compact interface" by default; themes, with line in config file
129 to load pixmaps from pixmaps/$THEME/ (see Jan 9, 2009 emails)
130 - horizontal mode instead of dual-view / multicolumn ?
131 ** "new page before/after" on a PDF bg page should ask: same page, other page of
132 PDF file, default paper
133 ** should also have in Journal -> Paper style the option "Pdf page ..."
134 which then lets us change the page number.
135 - new recognizer icon (andruk on patches tracker)
136 - recognizer: if variable-width, associate average width
137 - recognizer should snap to existing recognized geometric shapes
138 - patch to find text in PDF (dmg = Daniel German, Nov 13 2009)
140 - search through text (xoj and PDF background) (with highlight? forwd/backwd)
141 (see evince). Also: ability to select rectangle on PDF bg and copy-paste
142 as bitmap or as text.
144 - improve recognizer: two passes for polygons (low tolerance, then higher)
145 to better detect elongated rectangles? (if low tolerance recognizer
146 doesn't get a rectangle, then use higher tolerance for everything else,
147 since otherwise there's too much risk of splitting a segment into 2)
148 - snap-to-grid (also for ruler & recognizer vertices)
149 and maybe also snap-to-vertices (option for ruler and recognizer)?
150 - config option: config save current tool options instead of default ones
152 - bug in truetype subset generation w/ Adobe 9, see if gtk-print any better?
154 - drag-and-drop, copy-paste text & images directly into xournal
155 - proximity detection: eraser proximity switches mapping?
156 proximity out removes cursor until next motionnotify?
158 - render page to bitmap: for export, preview, and copy-paste
159 (render using libart, see how gnomecanvas does it?)
160 NO: render using Cairo !!!
161 (copy-paste: config option to render only current layer or all below?)
162 - cut-and-paste of selection into other apps (as bitmap; as SVG?)
164 - navigation sidebar with bitmap page previews
165 - bitmap preview for document icon in desktop environments?
166 - "organizer" side panel (hierarchy of notes), cf. gjots
167 - maintain e-library: table of md5sums of pdfs with associations
168 to the corresponding xoj's absolute paths (cf. forum topic
169 "Use MD5..." of Dec 2009)
171 - see iRex code for generic viewer + PDF plugin including caching,
172 throttling etc. (Marcel Hendrickx email of Sep 11 '09)
174 - allow toolbar to go vertical
175 - toolbar buttons should react to button 2/3 click to modify settings
178 - paste text directly into xournal, from xournal?
179 (instead of starting a text item and pasting into/from it)
180 - insert links (to URLs; within document/to other xoj? hand mode navigates)
181 - a command + keyboard shortcut to switch mappings (1<->2, 1<->3, 2<->3)
182 (A. Rechnitzer Sept 11, 2007)
183 - modify encoding of TrueType font subsets or provide cmap so pdf text
186 - smoothing of strokes (for users without tablets / with deficient drivers)
188 - add config option to limit total memory usage for PDF bitmaps
189 - ability to select entire page for copy-paste (as bitmap / reorder xournal)
190 - copy/paste of an entire page (beware if PDF bg is not compatible!)
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]
