Screen rotation on Tornado WM6??

The question was: Is the screen rotation possible on Tornado devices (for example for better Internet browsing).
Many efforts were done to gain this possibility. We have not fully received what we need, but we're on good way. We know now that the standard Tornado DDI.DLL driver is uncapable of screen rotation, so we (partially) replaced it with one taken from HTC Vox ROM. There is one serious disadvantage we're still working about: the joystick doesn't follow orientation for now, so using the phone in landscape mode is seriously difficult. We will be trying to adopt the Vox's keybddr.dll into Tornados.
I have collected all these things in an application, that you can install to skip manual registry editing.
Here is the application:
http://www.mediadrain.com/TDM_1.0.0.cab
You MUST install the following certificates! If not, a hard reset will be required!

To rotate the screen select Change Driver option from the Display Driver option, and change to a VOX one.

i don't think it will be supported on this alpha version...!!!

OS either supports screen rotation or not

WM6 supports screen rotation, like on the vox, so surely we could do the same for tornado but add some start menu shortcuts or a home screen plugin to make it rotate?

i tried writing an app in .net compact framework. While it worked and rotated a PPC WM5, it didn't work in my SP WM6.
maybe .net is hard-coded and disallows screen rotation on smartphone, what doesn't mean it's impossible

may you need the dll file from VOX which enable the screen rotation by opening the keyboard

i think we should write a list with Q&A, and other with Bugs, Do have somebody a list with a resume of troubles...??

i build a .NET project that allow to rotate the screen, but for me it works ONLY on emulator SDK only in both WM5 and WM6 why? i post the exe and the source.. give me some answer..

Hey, I have a Vox (s710) for a few days so I could search which application is used by this phone to rotate the screen.

that would be great mate. we'll be waiting for it.

bad news...
i found this somewhere in eMbedded VC++ documentation:
Screen rotation requires support from the display driver, which maintains information regarding rotation. Screen rotation is currently supported only on devices that use a single screen and is not supported on multiple screen devices.
An application calls the ChangeDisplaySettingsEx function to determine the screen orientation modes that the system supports, to set the angle by which the screen is rotated, and to query the current angle of rotation

I've written small utility (C++, native code just to be sure that no funny hardcode in compact framework is messing) and i've tested it on SPV C600 and TYTNII. On TYTN all was OK (screen rotated), on C600 (WM6) error was 'DISP_CHANGE_BADMODE' - exactly like described in docs...
so (IMHO): display driver (heh.. I suspected that there is sth like display driver ) just does not support screen rotation, so no matter that WM6 supports it...
we got two choices:
- find better one (heh... i do not even know the name of the file... but this i can find - i think i saw it once where i was plaing with regedit )
- live with 0 degrees rotation

It is necessary patch driver from vox. It approaches, but incorrectly turnoff screen. Illumination does not die away, and after that the image is displaced on 15 pixels to the right. With the all perfectly rotates. Except for joystick...

could you uploader the driver plz

How can I find the driver in the ROM?

http://kmz.ho.com.ua/dispdriver.vox.zip
Here the driver and the certificate by which is signed the driver.

so we got POC done, now time for hard reset
driver supports screen rotation, but it got problems with display time out - when backlight should be off it is on, but screen becomes white and it's premament (until reboot).
Just for info - U can use MyMobiler to operate - no matter that screen is dead, phone itself is still doing his job

Hey, that is great
Good job guys, i'm sure you guys can improve it.
Just some suggestion, perhaps you can make some application which will toggle landscape/potrait and map it to one of the shortcut keys such as long_volup

Excelent work Qlphn, what about the joystick control? It changes the way to control the Joystick when you switch to Panorama Modus?
THX

Has anyone got the Tornado display driver? I could probably check differences with windiff and hexedit it .

Hey!
I managed to do this with DDI driver you've attached.
Well, the joy doesn't follow orientation, screen rotation works. After some time my display takes weird colours. I hope this can be fixed anyway, well I will try to work it
Maybe only registry edit is required? I will compare vox registry with tornado one and say what I noticed.

DirectShow Camera Control On TMobile Shadow

Hi All,
I am using DirectShow API for fetching camera contents on T-Mobile Shadow phone (manufacturer is HTC). I am having problem with the default Camera Zoom factor on this phone (when opened using DirectShow). I am trying to control the Zoom factor using IAMCameraControl interface. But I don't get any valid pointer for IAMCameraControl Inteface by using following code =>
$$$$$$$$$$$$$$$$$$$$$$$$$$$
long camera_flags = 0;
long zoom_val = 0;
IAMCameraControl* pCameraControl = NULL;
pVideoCaptureFilter->QueryInterface(IID_IAMCameraControl,(void**)&pCameraControl);
if(NULL == pCameraControl)
{
result = E_NOTIMPL;
goto error_handler;
}
$$$$$$$$$$$$$$$$$$$$$$$$$$$
Looks like IAMCameraControl has not been implemented on this particular phone. Is there any other way to change default Camera Zoom factor on HTC phones?
I came to know about HTC Camera DLL using this forum. How should I go about getting the Camera DLL and the documentation?
Thanks,
Shashi

(Tweak) Real fullscreen browsing on HD2!!

Hi guys!
Frustrated with the Opera browser on the HD2, I decided to take matters into my own hands
What really bugged me was the inability to see the whole page when browsing the web, and by that I mean go fullscreen… This is possible on the iPhone, Nexus one, Hero, Pre etc. but not on the HD2!
The reason behind all this: Virtual Screen Width….
The resolution on, lets say the iPhone, is poor 480x320… Most webpages are AT LEAST coded in 1024x768…
The reason why the iPhone, with its inferior resolution, is able to go fullscreen on most webpages, is because Safari lets the iPhone use Virtual Screen Width… "Virtual" is the keyword here …
On the HD2 we are blessed with the wonderful native resolution at 800x400 pixels .. This is all great, but there is one problem: Its not 1024, 1156 or 1280… Its 800x400… = 800 in width = crippled page view!
The problem is that Opera, on default, isn't configured with any sort of "virtual" screen width… It is 800 pixels all the way…
But!
We can activate the Virtual Screen Width, and thereby go fullscreen on any webpage= No more crippled web browsing!
Go to:
[HKEY_LOCAL_MACHINE\Software\Opera\Prefs\Adaptative Zoom]
Change "Virtual Screen Width" from "800" (The native screen width) to "1024", "1152", "1280", "1366" or whatever suits your browsing needs
My configuration is like this (Gives a good overview, without destroying visibility):
[HKEY_LOCAL_MACHINE\Software\Opera\Prefs\Adaptative Zoom]
Virtual Screen Width: 1024
Hope you guys enjoy
Update: Some people are experiencing some problems with "double tab to zoom"... This most likely has to do with another tweak in relation to "Default Zoom" in [HKEY_LOCAL_MACHINE\Software\Opera\Prefs\Adaptative Zoom] .... If you have changed this value, please change it back to value "175"... My browsing experience is perfect... Fullscreen, double tab, smooth etc. To me the HD2 is now a real internet device
Update 2: Here are some other tweaks, provided by astrodemoniac in another thread: http://forum.xda-developers.com/showthread.php?t=626157
I post it here to create a better overview of whats possible "tweaking" wise on the Opera Browser:
Increase Scrolling FPS:
[HKEY_LOCAL_MACHINE\Software\Opera\Info]
PanFps=50
Increase Zooming FPS:
[HKEY_LOCAL_MACHINE\Software\Opera\Info]
ZoomFps=50
Lower Default Zoom:
[HKEY_LOCAL_MACHINE\Software\Opera\Prefs\Adaptative Zoom]
Default Zoom=100 (I would advise to just keep it on 175, as it works perfectly with my fullscreen tweak.. Some people lose "double tab to zoom" when editing this value.. Keep it on 175!!
+ these tweaks (mainly from tboy2000):
Increase the font cache for displaying text quicker:
HKLM\Software\Opera\Info\
fontcachesize = 64
(default was 32)
Source: this thread (item #76)
Complete page loading = Avoid the unfamous "checkerboard background"
HKLM\Software\Opera\MemoryLimits:
AllocLimit = 70254592
HeapLimit = 73400320
memory_heap_threshold_size = 131072
mmap_reserve_size = 20971520
sbrk_reserve_size = 49283072
Source: this thread (item #76)
If using the newest Opera build from 1.67:
Enable this new Opera to open favorites on the Sense internet tab
HKLM/Software/Opera/Info
UseOperaBookmark = 0
(default = 1)
Enable this new Opera to download files on Storage Card
HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ SDMemory
Folder = Storage Card
Thx!

I'm not sure I got this right...
- Does your tweak work on landscape or portrait? Because this thread here already talks about full screen in, I believe, portrait views. Will you tweak have influence on both portrait and landsape?
- Could you make a screen capture, so we can understand? (BTW, BsB tweak use very simple ways to make screen captures)

It works in both portrait and landscape.. The tweak you refer to adjusts the zoom levels... Not the visual width....
You can see "my" tweak as the key to full screen browsing like on your laptop or whatever... It makes your screen "believe" its actually, lets say 1024 in width, instead of 800... An amazing difference.. Try it out and you will never go back

Nice find!! The full page view is indeed awesome!
But i noticed that double tap zooming doesn't work anymore. But who cares! The fullpage view matters more.
Thanks!

thanks
but it lose the double tap zoom function

Niiiice!!!
I dont lose double tap zooming..!!
(maybe cause i applied all the tweaks for smoothness etc plus this one in the latest opera from 1.67 rom..found here i think!)

Maybe is due to opera build. Mine is 9.7 build 35627. I think I probably should upgrade to the newer build.
Edit :
The double tap zooming is gone when this tweak is used with this,
Lower Default Zoom (Really takes advantage of the HD2 beautiful screen)
[HKEY_LOCAL_MACHINE\Software\Opera\Prefs\Adaptative Zoom]
Default Zoom=100
Simply change the default zoom back to 130 and double tap zooming will work again.

I also loose double tap to zoom, but only in portrait mode. In landscape it is ok. I set the screen width to 1024. Also my registry key is called 'Virtual Screen Width' not 'Visual Screen Width'
My opera build is 9.7 build 35577. I am on ROM 1.48.405.2 WWE
BTW my original value for the Default Zoom is 175 not 130. I have tried using 130 but it doesn't work. The only way it seems to get the double tap to work in portrait mode is to change the screen width back to 800.
Pinch zooms works ok though.

Are we actually talking about the "VIRTUAL SCREEN WIDTH"
Changed the setting to 1024, looks good. Thanks for the tip

+1 double tap zoom is gone

change to 1000. double tap work in portrait (and landscape)
with 1024 work only in landscape, for me (and you)

Nomination
A real beauty, this tweak. Thanks for sharing.
I would like to nominate this tweak, together with the default zoom-level tweak, for a Grammy Award in the category `best Opera tweaks´
EDIT: added a little cab that changes the "Virtual Screen Width" to 1024. The benefit of using a cab is that when u unistall the cab, the default value is restored. (@ OP: feel free to attach this cab to your own post. The author rights are all yours )

i would actually advise people that those who want to still be able to use double tap zoom to not use this cab.
By default, 1024 disables double tap.
I recommend 1023, or better, 1000.
I figured this trick not too long ago.
See my post. http://forum.xda-developers.com/showpost.php?p=5510142&postcount=3

Not fully related, but is there a way to disable the soft buttons always appearing during page loading? I find it highly annoying that it always brings the buttons and address bar up, rescaling the page at the same time, and making it a pain to scroll during loading... I only need those if I press the bottom right "menu" button, not all the time automatically...

I have no problems with the double-tap zoom feature. I'm on opera 9.7 35758. What version are you running? (sounds like a weird bug to me)

Changed it to 1280... look awesome, still have my double-tap. Haven't updated my Opera build yet.

Great, it really works fine and should have been the default parameters for Opera!!! I really can't understand why a community like ours is able to change some simple numbers and get the best out of our HD2 ! Anyway, here are the tweaks I use for Opera from now on:
Fullscreen view on portrait and landscape (actually "Full Width")
This enable a webpage to be fully seen when you first load the page.
HKEY_LOCAL_MACHINE\Software\Opera\Prefs\Adaptative Zoom

Damn... I think we really need some BIG CAB to easily change this all... I just don't know how to make it. Help

I changed my pinch zoom framerate to 50 the other day, and yes, it's much better... but is there a way to increase the rate of zooming. I don;t like having to pinch several times when on my 3GS I only have to do it once. I know I can just double-tap, but still...

[Q] Intercepting the accelerometer ?

Hello,
Another simple question:
I am developing a game on Android. Whenever the device (equipped with a accelerometer) turns sideways, the app RESTART on a rescale landscape display.
I don't really mind the graphics rescaling (my work, to accommodate different screen size..), but I mind the whole state of the game being reset!
So, my question is:
How can you intercept the accelerometer movement so that the app will NOT reset the display, landscape/Portrait, and hence the app ?
I've tried installing a SensorEventListener in the Activity class, and I was able to read the accelerometer, but not to intercept/avoid the resetting of the graphics sideways.
I've seen code that seems to work as I want to in an OpenGL app with overriding "onSurfaceChange(GL10 gl, int width, int height)"
But my game isn't OpenGL.
Is there an equivalent on "Activity" ??
Thanks!

Found my answer:
android:screenOrientation="portrait" in manifest.xml

[Q] How to get orientation of photo taken from camera

Hi All,
I am trying to get the photo orientation, which is captured from camera, using
ExifInterface exifReader = new ExifInterface(imagePath);
int orientation =exifReader.getAttributeInt(ExifInterface.TAG_ORIENTATION,-1);
I have tested the same code on three different android devices.
1) On Micromax A60 android ver 2.1
orientation value is always 0 which is ok because it saves the image in the same orientation as it is being captured.
2) on Samsung Galaxy pop Gts5570 android ver 2.2
orientation value is 1 if image is landscape
orientation value is 6 if image is portrait
3) on Samsung Galaxy GtI9003 android ver 2.2
orientation value is always 1
so in the last case How to find the orientation information of image ???
What does it mean in third case why it always gives the 1??
any one having Idea on this then please help me on this..
Thanks in Advance
