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?
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 (???)
39 PATCHES TO INCORPORATE:
40 ** patch: ortho/snap (revised Apr 13 2009)
41 xournal_ortho_snap_patch_4 (by Josef Pavlicek)
43 ** patch (Ian-Woo Kim): multicolumn mode + LASSO SELECTION
44 xournal_lasso_multipage_zoom_button_20090620.patch
46 ** autosave patch (Edward Yang) (should fix: optional only, w/ menu + cfgfile
47 entries; fix: should clean up autosave.xoj.bg* files too; config interval)
48 0001-Implement-autosave-for-documents-revised.patch (2 seconds after
49 modification, vs original 5 seconds)
50 *** NEW VERSION: #2881919 (autosave for 0.4.5, w/ some changes)
51 NB: last modif should be triggered by prepare_new_undo() and undo/redo?
52 *** NEW VERSION: with threading, by Man, e-mail 12/10/2009 10:51pm
54 ** insert images patch (Victor Saase) #2890925
55 ** as improved by Simon Guest April 14 2010
56 ** modified rev2 May 14, 2010: xournal-0.4.5-sjg-image-rev2.patch.gz
58 ** customize paper ruling (Gautam Iyer e-mail Nov 30 2009 / SF tracker)
60 ** cairo export to PNG (Man = Paulo Neves, e-mail Feb 3 '10, saved as
61 cairo-png-rendering.diff.txt (refactor printing of page to cairo surface
62 with the gtk-print code).
64 - make default in ok_to_close() box "cancel" rather than "no".
66 - make line spacing in text objects customizable: to a fixed scaling factor,
67 a fixed number of units, or the paper ruling (esp. the latter!!)
69 - page size dialog box should have a check button to keep background size
70 the same (so rescaling creates margin around bitmap or PDF background).
71 This will need an extension to the file format, to allow a page background
72 to have a different size from the page itself.
74 - option to map device named "touch" to hand tool? (like "Eraser tip")
77 - roadmap towards SVG support: see 1/25/2010 Mark Edgington email & reply
78 (1) export to SVG (using pages and groups for pages and layers;
79 use comment tags to make export nonlossy;
80 (2) import from this subset of SVG;
81 (3) add SVG to the file-open and save formats
83 - roadmap towards PDF encapsulation: see 1/29/2010 forum posts
84 When exporting to PDF, don't just append our annotations as PDF code but
85 also include the .xoj file within the pdf, and ensure the initial pdf is
86 well-delimited from the rest. When opening a PDF that includes such
87 markings, discard the annotation part of the PDF and open the embedded xoj
88 instead. Later, offer such PDF as a file-open and save format (even when
89 there's no PDF background being annotated!!).
91 *** should have Open, Save, Save As manipulate at least 3 formats:
93 - PDF with embedded xoj file in an object (opens with annot. in PDF viewer,
94 with background only + separate xoj in xournal)
96 additionally, should have "print to": printer, PDF, SVG, bitmap.
98 - allow djvu and other backgrounds (but then can't export to PDF)
100 - PDF bg memory usage throttling / delete oldest pdf backgrounds
101 - replace ttsubset by something more modern? (eg. from cairo ?)
102 - auto-hide patch from ~/prog/src/xournal-autohide/ ?
103 (check for cpu usage; handle BOTH edges
104 and only (un)hide stuff at the correct edge!)
105 ** UI update (Bob McElrath) -- eliminating status bar, compact layout,
106 "compact interface" by default; themes, with line in config file
107 to load pixmaps from pixmaps/$THEME/ (see Jan 9, 2009 emails)
108 - horizontal mode instead of dual-view / multicolumn ?
109 ** "new page before/after" on a PDF bg page should ask: same page, other page of
110 PDF file, default paper
111 - new recognizer icon (andruk on patches tracker)
112 - recognizer: if variable-width, associate average width
113 - recognizer should snap to existing recognized geometric shapes
114 - patch to find text in PDF (dmg = Daniel German, Nov 13 2009)
116 - search through text (xoj and PDF background) (with highlight? forwd/backwd)
117 (see evince). Also: ability to select rectangle on PDF bg and copy-paste
118 as bitmap or as text.
120 - improve recognizer: two passes for polygons (low tolerance, then higher)
121 to better detect elongated rectangles? (if low tolerance recognizer
122 doesn't get a rectangle, then use higher tolerance for everything else,
123 since otherwise there's too much risk of splitting a segment into 2)
124 - snap-to-grid (also for ruler & recognizer vertices)
125 and maybe also snap-to-vertices (option for ruler and recognizer)?
126 - config option: config save current tool options instead of default ones
128 - bug in truetype subset generation w/ Adobe 9, see if gtk-print any better?
130 - drag-and-drop, copy-paste text & images directly into xournal
131 - proximity detection: eraser proximity switches mapping?
132 proximity out removes cursor until next motionnotify?
134 - render page to bitmap: for export, preview, and copy-paste
135 (render using libart, see how gnomecanvas does it?)
136 NO: render using Cairo !!! then can switch to GtkPrint as well.
137 (copy-paste: config option to render only current layer or all below?)
138 - cut-and-paste of selection into other apps (as bitmap; as SVG?)
140 - navigation sidebar with bitmap page previews
141 - bitmap preview for document icon in desktop environments?
142 - "organizer" side panel (hierarchy of notes), cf. gjots
143 - maintain e-library: table of md5sums of pdfs with associations
144 to the corresponding xoj's absolute paths (cf. forum topic
145 "Use MD5..." of Dec 2009)
147 - see iRex code for generic viewer + PDF plugin including caching,
148 throttling etc. (Marcel Hendrickx email of Sep 11 '09)
150 - allow toolbar to go vertical
151 - toolbar buttons should react to button 2/3 click to modify settings
154 - paste text directly into xournal, from xournal?
155 (instead of starting a text item and pasting into/from it)
156 - insert links (to URLs; within document/to other xoj? hand mode navigates)
157 - a command + keyboard shortcut to switch mappings (1<->2, 1<->3, 2<->3)
158 (A. Rechnitzer Sept 11, 2007)
159 - modify encoding of TrueType font subsets or provide cmap so pdf text
162 - smoothing of strokes (for users without tablets / with deficient drivers)
164 - add config option to limit total memory usage for PDF bitmaps
165 - ability to select entire page for copy-paste (as bitmap / reorder xournal)
166 - copy/paste of an entire page (beware if PDF bg is not compatible!)
167 - rewrite printing using GtkPrint + Cairo as GnomePrint replacement
168 (keep GnomePrint option for compatibility with GTK+ <2.10)
169 - insert images (screen capture or from file or from clipboard),
170 not as full-page backgrounds (new ITEM type)
172 - convert to/from Jarnal format; to/from MS Journal format???
173 - export as SVG, as bitmap (use Cairo for this)
174 - improved PDF viewer features (search text, hyperlink, page borders...)
175 (using full poppler api ?)
176 - search text: among PDF background (using poppler); among text annotations
178 - use system paper size as default (/etc/papersize)
179 - sticky notes (anchor visually text box to a bg location)
180 - use relative paths for bg documents (e.g. annotated PDF)
181 - flush display queue when drawing over a slow X server?
182 - more paper customization (in particular, 1/2 inch graph paper)
183 (2 custom papers with settings in config file?
184 a folder with blank PDF or xoj papers and quick-access?)
185 (also: engineering paper; isometric paper -- Dan Ott Sep 4 '09)
186 - option to map a button to a context menu (incl. tool selection, ...)
187 - option to map a button to "undo"
188 - xournal_page-shadow.diff (Martin Kiefel Feb 5 2007)
189 - xoj2pdf on command line
190 - 'insert blank page after' command (more useful in PDF annot !)
191 - load images as bg if given on command-line (as with PDF on commandline)
192 - lasso selection tool (see shoffsta patch)
193 (http://shoffsta.afraid.org/Projects/Xournal/)
194 - flatten (incl undo/redo...) - enabled only if nlayers>1
195 - color chooser (papercolor, pen color); have default colors and a history
196 appear as palette in there!
197 - printing: print-options, save printer settings (throughout a session,
198 and on disk) (maybe a separate config file .xournal/gnome-print-settings)
200 - option for highlighter to be always at bottom of its layer
201 - more pen/highlighter shapes (chisel)
202 - slanted tip pens (calligraphy)
203 - toolbar buttons to access custom preset tools (e.g. text or pen with settings)
204 - text boxes with opaque background
205 - recalibration upon screen resize / compensation for miscalibration
206 (use ConfigureNotify event and XInput? cf "Bugs" tracker 08/2007)
207 - find a better behavior for vertical space tool across page boundaries ?
208 config options? 1) when there's not enough space at bottom of page:
210 - move stuff to next page
211 - move stuff to a new page
212 2) when moving to another page:
214 - move only what doesn't fit (??? looks hard)
215 option for vert space tool to also move the background??
216 (PDF: cut-and-crop by running PDF code twice with 2 different clipboxes?)
217 - option to save all annotated files within the .xoj
218 - non-antialiased version for handhelds
219 - customize autogenerated save file names
220 - layer dialog box to set visibility status of each layer regardless of
221 which layer is being edited
222 - option to link layer creation and visibility status for all pages
223 (Eric Borghs 04/15/08)
224 - display corruption on scroll down when bottom of window is obscured??
225 (probably a gnomecanvas or X bug -- expose event generated for wrong
226 region, or not processed?)
227 - autosave at a regular interval in a given location
228 - keep only a few pages of a PDF file in memory at any given time; generate
229 pages by parsing pdf info rather than generating bitmaps for all of them.
230 - win32 port (Matteo Abrate)
231 - snap-to-grid tool? (Matteo Abrate)
232 - EPOS 7/24/07: Thumbnails pane
233 - EPOS: Connect to EPOS api which sends A4 mapped points
234 - EPOS: Cut and Paste into OpenOffice applications and the GIMP (as bitmap??)
235 - EPOS: Export pages to pictures in the Jpg and Png formats.
236 - EPOS: Rotate Ink in custom angle.
237 - handwriting recognition???? (cellwriter?) unlikely. we don't have grids
238 see galileon comment on 2008-07-29 to tracker #1925309: word recognizer
239 - handwritten stroke search in document (see cellwriter?)
240 (correlate inertia-normalized strokes in lift to unit cotangent bundle?)
241 - option: export to PDF with incremental pages for successive layers
242 (for presentations) (Daniel Brugarth 8/18/07)
243 - Samuel Hoffstaetter: lasso, gettext localization, sidebar thumbnails, ...
244 - YoYo Siska patch for desktop mode ??
245 - Vivek Ayer: rotate paper wrt screen (for environments where display
246 rotation doesn't work): gnome_canvas_item_affine_relative(canvas->root, ...)
247 would rotate all but text items (still need to modify scroll bbox, and
248 adjust event coordinates by inverse rotation).
249 - rotate PDF background pages (individually wrt each other, see #2099935)
250 - switch to libglade, and allow customization of key shortcuts (accels)
252 - command to copy a selected shape to a keybinding that will paste it
253 (so one can define symbols to insert into typed notes) (e.g. "be able
254 to bind Ctrl-B to draw a \beta" for class notes). (shape, binding) sets are
255 local to one session (different for different classes; but save them into
256 the xoj file maybe ?) [Felix Giannelia 09/29/2009]
