Hi All,Unfortunately I forgot to send my status last week, hence this is the combined summary for the last 2 weeks:
=== 07 / WK27 ==
* Worked on moving Calc's column/row-bars to using Virtual-Device
scaling rather than pixel coordinates, meaning they now match.
** Still some issues with scrolling, probably the various invalidate
and update calls mixing pixels with document coordinates.
* Implemented a quad-tile test widget.
** Used for the gtk test app.
** Planning to move this into a separate widget, and allow selection
within the gtktiledviewer to test the production widget or the
quad-tile widget.
* Fixed border transition issues -- just more confusion with
Rectangle's definition of its boundaries. (Affects the svp backend.)
[ See writer_quad.png for ugliness around the border transition, now
fixed. ]
=== 08 / WK28 ==
* Impress Tiled Rendering: implemented.
** Hard to find where we can plug tiled rendering in, but once found
wasn't much work to implement.
** Foreground images not rendered yet (same thing happens in Calc -- is
a shared bug AFAICT).
[ See impress_noimage.png ]
** No switching between slide/notes/both yet (currently defaults to
last used mode).
* Added part selection to gtk tiled viewer (and cleaned up the API
for both LOK and the tiled widget).
[ Dropdown menu, also visible in impress_noimage.png ]
* Basic Tiled Rendering test implemented.
** Only partially enabled -- still some issues with viewports in the
drawing layer -- content of document matches except for the page
edges -- however a tentative viewport fix also fixes this (but I
don't yet understand the code, so won't push that to master until
I know what's actually going on -- once done the unit test can
be fully enabled / extended to sd (and later sc)).
** [ See test_assembled.png to see a larger tile assembled from 4
sub-tiles -- when drawing the same area as one larger tile, the page
edges all look like they do in the top-left sub-tile -- with my
temporary/branch-only viewport patch all the edges are now drawn
consistently, as visible in the sub-tile pasted on top. ]
* Merged Impress work + tests + viewer improvement to master (and also
rebased the calc work on top of that, now in
feature/calctiledrendering4...).
* Modified gtktiledviewer to allow selecting between the normal
and quad-tiled widget.
** (We could use the gtk/glib inheritance mechanisms to make the
quad-tile widget extend the normal widget (and thus retain
full functionality), however it seems wasteful to add
virtual methods etc. to the widget just for this purpose, instead
the quad-widget is a duplicate, albeit with some features now missing
(i.e. no real point in duplicating new features from the usual
widget). Moreover, the main widget is (hopefully) likely to evolve
away from rendering of a large fixed tile -- whereas keeping the quad
tile widget may be of some use even if the main widget implementation
changes.)
