Subject: [E-devel] [Patch][elm_map] Add overlay in the map
I made a overlay APIs in the map. This will replace the marker APIs.
I hope that markers will be deleted before elementary 1.0 release.
This was discussed before in
http://marc.info/?l=enlightenment-devel&m=132685497711772&w=2
Marker only supports layout style overlay. So only icon and image are
suitable for marker. For now on, overlay can support any evas object
and also layout style.
Currently overlay support default, bubble, and class types. And more
types will be added (Polyline, Polygon, scale, POI etc.).
I made a Elm_Map_Overlay opaque structure for handling general overlay
properties (hide, pause, show, etc.) and coordinates or internal
content (icon, content, etc.) for those different types.
Class type overlay is something like mixture of previous marker group
and marker class.
If member overlays in the same class are closed, they will be grouped.
(Same functionality as previous maker group.) The group's properties
and contents are defined by using general overlay functions. (New
functionality)
This defined properties and contents can be be propagated to member
overlays appended to this class. (Same functionality as previous
maker class.)
There are some missing functionalities remained. Group callbacks are
not supported yet in the overlays.
So images inside group bubble can not be shown. I will implement this
feature.
After this patch, I will fix signals and function names before
elementary 1.0 releases.

===============================
Previsouly i have tested rotation with old version of gesture layer in
touch devices.
Recent gesture layer gives somewhat different event information. So I
fixed it accordingly.
I tested this patch in touch-enabled device.

Subject: [E-devel] [Patch][elm_map] Refactoring Elementary Map
I have done refactoring & code clean-up in elm_map. Event if this
patch have much changes, refactoring & code clean-up jobs almost
always do.
Anyway, code is shortened and optimized I think.
I have done following jobs in my patch.
(1) Always change child size
Scroller Child size is changed when integer zoom level is changed
before. This makes bugs which mouse pointer is not correct on the map
when map is dragging.
Now, scroller child size is always changed when double zoom level is
changed.
(2) Evas map
Evas map is used for rotation & zooming before. But now it is used for
only rotation. evas_object_resize() can do zooming because (1) makes
child size always changed.
(3) Grid & Marker & Route, etc.
Because of (1), all coordinate calculations are all changed. So grid &
marker & route should be changed.
When I have fixed these, I have these split into small function
(create, free, update, place, etc.)
So these can be easily reused for other purpose ( I will add overlay
later.)
Also marker size is not changed and is not rotated anymore because
marker's coordinate is just rotated and evas_map is not used for
marker.
And grouping algorithm is somewhat changed. Each marker can be group
leader and if other markers (followers) are closed to leader, markers
are grouped.
Actually _marker_place() function do almost everything. (place marker,
bubble, group & make group, etc.)
Bubbles go along with parent object. (show, hide, move) and this is
created when marker & group are opened.
At now, bubble display bugs are all fixed.
As before, grid is created when elm_map_add() or tile source is
changed. And I add _grid_item_* functions for each 256x256 tile
management. So grid_place() function can be simple now.
(4) Download idler
Before download is not a job or idler and is integrated with grid
calculation.
I have separated this into independent idler. So now, download idler
do download jobs when idler time.
(5) Zoom
I have made one zoom_do() function. This does all zoom jobs. At now,
pinch_zoom & wheel_zoom & animated zoom do not much jobs. just call
zoom_do().
(6) Delayed jobs
As I know, evas is based on a retained mode and calculation can be do
later. So sometimes elm_map APIs can not do the jobs correctly.
For example, elm_map_marker_list_show() or elm_map_zoom_set() can not
be used right after elm_map_add() because window size and pan size
can be 0. (refer map_example_02.c)
So when APIs related such calculation are called. These are deferred
and calculated later when _pan_calculate() is called.
5) Code clean-up
I have removed unused variables & functions. and rearranged struct &
functions & declaration & static variables, etc.
Instead of "if (!wd) return; ", I changed this by macro,
"EINA_SAFETY_ON_NULL_RETURN(wd);". This is better for function
entrance check. Also ELM_NEW is used instead of calloc or malloc.
Aboves are all related each other. So it can be hard to split this
file. If these should be splitted, I'm going to freak ;D.
This patch does no harm!!!! :D.
After this patch, I will add overlay APIs based on this patch. I
doubt whether I will add this before elementary 1.0 release. :(

Subject: [E-devel] [Patch][elm_map] Fix zoom & rotated coordinates bug
In my point of view, elm_map did not consider zooming & rotation by
using Evas_Map initially.
There are no problems if you use only elm_map_zoom_set(). But if you
use pinch gesture or wheel to do subtle zooming & rotating, the
calculations of coordinates are not correct currently.
I have fixed these problem and also made some utility APIs for user
convenience.
I made following 3 APIs.
1. elm_map_utils_size_get()
Currently users can only get integer zoom level by using
elm_map_zoom_get().
So if user want to calculate full map size, user should calculate
pow(2.0, zoom level) * tile size. Furthermore, user assumes tile size
as 256. (tile size can be changed!!)
Also it's not correct sometimes because Evas_map is used for subtle
zooming between zoom levels.
Above APIs return correct full map size.
2. elm_map_utils_region_get()
It can used for getting left top coordinates, center coordinates and
width, height of currently shown map area.
3. elm_map_utils_convert_canvas_into_geo()
Currently it is hard to converting x, y coordinates to geographical
longitude, latitude because of subtle zooming & rotating.
If use wants to get it, user uses combination of above functions and
more. It is harsh job.
This function is used for getting longitude, latitude from x, y
coordinates of current viewport.

Subject: [E-devel] [Patch][elm_map] Smooth stepping of wheel & pinch
gesture
When elm_map doing zooming by using wheel gesture, scroller is resized
if it exceeds certain limit.
But current limit value is 2.0 & 1.0, actually those should be below
2.0 and above 1.0.
The reason is that resizing means exactly 2.0 or 1.0. So if it is
above 1.99x, it can be 2.0 and can be resized.
In addition, pinch.level & pinch.diff values should not be 1.0 or 2.0
for more accuracy. It should be half of previous pinch level or two
times of that.

Subject: [E-devel] [Patch][elm_map] Pause progressbar animator when
map is paused
When map is paused by using elm_map_paused_set(), all existing
animations is stopped.
(ref:
http://docs.enlightenment.org/auto/elementary/group__Map.html#ga6ab43ef6429140f8cccbd3669c5ed52e)
But progress bar can be still running before all download requests are
completed. It is equal to user expectations.
I have fixed this.
if paused is TRUE, stop progress bar.
If paused is FALSE, start progress bar if download requests are
remained.
SVN revision: 66585
Dear all,
I have found a bug that calculation fails when view port size is
bigger than map size.
For example, if map size is 256x256 but view port size is 798x798
(when zoom level is a 1), center longitude & latitude is out bound
from normal longitude & latitude.
I have fixed it.

Subject: [E-devel] [Patch][elm_map] Mouse wheel bug fix
There is mouse wheel bug. Actually I have made it in previous patch :p
When using mouse wheel, tile size was changed between 0.5 ~ 2.0 before
zoom level is changed. But actually it should be changed between
1.0 ~ 2.0. I have fixed it. If tile size is below 1.0, it does zoom-out.
And if tile size is above 2.0, it does zoom-in.
SVN revision: 66459
Subject: [E-devel] [Patch][elm_map] Apply elm gesture
elm_map implement pinch gesture by using evas mouse event. But it made
codes too complicated and dirty.
So I have changed pinch gesture by using elm_gesture. wheel zooming is
also improved somewhat.
From now on, configuration change related elm_gesture easily applied
to elm_map and we can see more smooth zooming :D
Anyway, els_scroller have bugs when the scrolling event & the resize
event occurs at the same time.
So, some dirty codes are added for preventing jumping to strange positions.
Later it will be removed when the bugs are fixed.

(3) Simplify grid_load()
There exists 3 state for grid items. i.e., downloaded, downloading,
none states.
grid_load() does followings:
1. if a grid item does not exist, create it.
2. update a tile (if downloaded) or queues for download (if none) or
nothing (if downloading)

Subject: Re: [E-devel] [Patch][elm_map] Change grid management
(1) Grid Management
There are no caching mechanism in current elm_map.
So, too many network resources are wasted because elm_map keeps only
two grids and already downloaded images are downloaded again and
again. (This also slows the map loading speed)
I have changed this grid management policy.
I have done followings.
1. Create all grids (all zoom levels) when elm_map_add() is called (No
memory overhead because of sparse matrix)
2. Clear all grids when map object is deleted.
3. Loads necessary grids and unloads unused grids when zoom level is
changed.
Changed grid management have one weakness that memory and tmp size can
grow bigger while map object is live.
I think it may need API such as elm_map_cache_size_set().

Hi,
There are bugs that map removes list elements when using
EINA_LIST_FOREACH or EINA_LIST_REVERSE_FOREACH.
We should use EINA_LIST_FOREACH_SAFE or EINA_LIST_REVERSE_FOREACH_SAFE
instead for above case.

Subject: [E-devel] [elm_map] Fix up too many connections at the same
time.
Currently, elm_map requests all visible map image tile to map server
at the
same time.
If the scene is turned off while panning or zooming, it will be
aborted on
HTTP requests.
But it already sent to map server, and it already made useless HTTP
connections.
So if you pan scrolling quickly, elm_map try to download and abort too
many
HTTP
connections repeatedly.
If you have stable and high-throughput data connection, it doesn't
matter
on your side.
However map server will get high load, It is sufficient reason to block
you.
In another case, if you have poor data connection such as 3G
connection, it
has less
throughput and it causes delay of downloading. And finally, the device
is
as full as
HTTP connections even you already aborted. It makes low-performance
issue on
your device.
I wrote a patch for solving this situation.
The idea is simple.
1. I limited number of maximum HTTP request on elm_map side.
2. If maximum HTTP request is exceed, keep requests on Eina_List.
3. If each image downloading is completed, try to download recent
request.
(Because it has strong possibility for your screen)
4. At the same time, invisible request will be removed.
(It doesn't make HTTP connection yet)
I tested many times on my desktop and device.
It works for me. And elm_map's performance is improved
appreciably on 3G
connections.

When you test elm_map with mouse wheel, it worked abnormally because of some bug.
So I made some more patch for fixing it.
This patch file also includes a previous patch (zoom-out issue).
SVN revision: 63510
I wrote a patch that handles a bug while zooming-out in elm_map.
When I try to zoom out, some tiles are broken.
But it is hard to notice because broken frame disappears quickly.
I investigated in a few days.
And I realize that there are something wrong.
When map is zoomed out, a tile is shrunk by evas_object_resize().
But evas_map handles its texture by just its origin image size not a shrunk size.
If evas_object's width & height is shrunk, I have to handle for its texture.
