How to create mbm file?

[qt_raip]

I've been trying to create an mbm files for the whole day today, but I've been having problem???

I've tried doing it in the command line using bmconv

this is what I type in the command line:
bmconv /haknexspane.h aknexspane.mbm /c8context /c8indicato /c8indicatom /c8lshellicon /c8lshelliconm /c8navi /c8testimage1 /c8testimage1mask /c8title

but everytime it finish creating an mbm files this happens:

BMCONV version 103.
Compiling...
Multiple bitmap store type: File store
Epoc file: aknexspane.mbm

Bitmap file 1 : context
Bitmap file 2 : /c8indicato
Bitmap file 3 : /c8indicatom
Bitmap file 4 : /c8lshellicon
Bitmap file 5 : /c8lshelliconm
Bitmap file 6 : /c8navi
Bitmap file 7 : /c8testimage1
Bitmap file 8 : /c8testimage1mask
Bitmap file 9 : /c8title
File does not exist

It creates an mbm files but there's nothing inside it - 0kb...

If I include it in the mmp files it doesn't create an mbm files at all???

this is the code inside the mmp file:

START BITMAP plainrichtext.mbm
HEADER
SOURCEPATH ..\aif
SOURCE c12 context_pane_icon.bmp
SOURCE c12 context_pane_icon_mask.bmp
SOURCE c12 list_icon.bmp
SOURCE c12 list_icon_mask.bmp
END

Help me please!!! ASAP!!! need to know what's wrong??
any help will be appreciated..

Perhaps try a command file:

eg: "s60.cmd"

/h..\inc\s60mbm.hrh
s60.mbm
/c16folder13x13.bmp
/1folder13x13mask.bmp
/c16file13x13.bmp
/1file13x13mask.bmp
/c16blank13x13.bmp
/1blank13x13mask.bmp
/c16error13x13.bmp
/1error13x13mask.bmp
/c16info13x13.bmp
/1info13x13mask.bmp
/c16warning13x13.bmp
/1warning13x13mask.bmp
/c16modifieditem13x13.bmp
/c16newitem13x13.bmp
/1itemmask13x13.bmp

and then to make the mbm:

bmconv s60.cmd

The above will create an associated .hrh file in an adjacent ..\inc folder as well as the required mbm.

Thanks so much it works now...

but when I type bmconv aknexspane.cmd this happen:

BMCONV version 103.
Bad command file.

Don't know what' wrong but happily it already creates the files I need tnxs so much!!!!

Hello, This:

bmconv /n /hresult/your_hdr.h result/your_mbm.mbm /c12src/icon001.bmp /1src/icon001_mask.bmp /c12src/icon001_list.bmp /1src/icon001_list_mask.bmp

works fine on my environment.

[result] is a folder on your workstation where generated files is copied.

[src] is a folder on your workstation where source bitmaps are located.

[icon001*.bmp] are the source bitmaps, 4 pieces at this time which generates 2 symbian icons for you. Each symbian bitmat consist of bitmap and mask.

If you need more icons just continue that parameter list with bitmap filenames.

BTW: Mask bitmap files should be defined to have '1' color, not 'c12'.

I think the problem on your commandline case was missing file extensions ?

And finally this mmp definition works fine in my environment:

START BITMAP your_mbm.mbm
TARGETPATH \system\Icons
HEADER
SOURCEPATH  ..\srcdata
SOURCE      c12 icon001.bmp
SOURCE      1 icon001_mask.bmp
SOURCE      c12 icon001_list.bmp
SOURCE      1 icon001_list_mask.bmp

Just adjust your enviroment to have source bitmaps on [srcdata] folder. May be TARGETPATH should also be changed to satisfy your needs.

Thanks for the help I know now what missing and I already figure it out!!

Hey! I know it's to much to ask but can some teach me how to create, load or just display bitmaps? I kinda having problems with the example in the SDK it this always happens:

C:\DIE\SENDO\GRAPHICS\SRC\Graphicscontainer.cpp(81) : error C2166: l-value specifies const object

this is what I put inside myDraw():

iBitmap = new (ELeave) CFbsBitmap();

please need help it's just a project I need to finish!!

tnx for the help again!!

[veskola]

[.h]
    CFbsBitmap* iImageBitmap;

[.cpp]
_LIT(KBitmapFile, "z:\\system\\apps\\sample\\sample_logo.mbm");

void CMyAboutControl::ConstructL(CCoeControl& aParent)
{
    SetContainerWindowL(aParent);
    iImageBitmap = new (ELeave) CFbsBitmap;
    CleanupStack::PushL(iImageBitmap); 
    User::LeaveIfError(iImageBitmap->Load(KBitmapFile,0));
    CleanupStack::Pop(iImageBitmap);
<...>
}

void CMyAboutControl::Draw(const TRect& aRect) const
{
    CWindowGc& gc = SystemGc();
    gc.Clear( aRect );
    TRect imageRect ( 0, 0, iImageBitmap->SizeInPixels().iWidth, iImageBitmap->SizeInPixels().iHeight);
    if ( aRect.Intersects( imageRect ) )
    {
        imageRect.Intersection( aRect );
        gc.UseBrushPattern( iImageBitmap );
        gc.SetPenStyle( CGraphicsContext::ENullPen );
        gc.SetBrushStyle( CGraphicsContext::EPatternedBrush );
        gc.SetBrushOrigin( TPoint( 0,0 ) );
        gc.DrawRect( imageRect );
        gc.DiscardBrushPattern();
    }

I've used your code but everytime I exit the apps the emulator crash!
but I can view bitmaps already...

Now I trying to load a PNG but everytime I open the apps the emulator crash!

Here is my code:

void CPNGContainer::ConstructL(const TRect& /*aRect*/)
{
CreateWindowL();
SetExtentToWholeScreen();
ActivateL();

iImageBits = new (ELeave) CFbsBitmap();
iConverter = CMdaImageFileToBitmapUtility::NewL(*this);
iConverter->OpenL(KPicFileName);
}

void CPNGContainer::Draw(const TRect& /*aRect*/) const
{
CWindowGc& gc = SystemGc();
gc.Clear(Rect());
gc.BitBlt(Rect().iTl,iImageBits);
}

void CPNGContainer::MiuoOpenComplete(TInt /*aError*/)
{
TFrameInfo frameInfo;
iConverter->FrameInfo(0, frameInfo);
err = iImageBits->Create(frameInfo.iOverallSizeInPixels,EColor4K);
TRAPD(convertErr,iConverter->ConvertL(*iImageBits));
}

void CPNGContainer::MiuoConvertComplete(TInt aError)
{
delete iImageBits;
iImageBits = NULL;
}

void CPNGContainer::MiuoCreateComplete(TInt aError)
{ /* no implementation */ }

Please Help!!! I just can't figure out what wrong with this....
I'm getting frustrated... : (

[qt_raip]

never mind about this I already figure out whats wrong! somethings wrong in draw...

tnx again for all the help!

[veskola]

Ok, nice you have got it work...i have been busy and haven't read board for a while.

Just as reminder, to get robust code, you should place error check at least in MiuoOpenComplete method. Try to place incorrect filename and run with debugger to check what can happen. It won't be good idea to continue conversion if opening fails... and what happen then on draw method, may be nothing catastrophic...

...and of cource you have delete iImageBits in destructor [why i'm asking this :-o]

Hey! in the past 3 days all I've been doing is trying to figure out how to convert and view multiple png and use the images as button???

but I can't find out y it won't work when I try this:

void CPNGContainer::ConstructL(const TRect& aRect)
{
CreateWindowL();
SetRect(aRect);
ActivateL();

iConverter = CMdaImageFileToBitmapUtility::NewL(*this);
for (CurImg = 0; CurImg<KImgID; CurImg++)
{
iImageBits[CurImg] = new (ELeave) CFbsBitmap();
switch (CurImg)
{
case 0: iConverter->OpenL(KMainFile); break;
case 1: iConverter->OpenL(KBackFile); break;
case 2: iConverter->OpenL(KNewFile); break;
case 3: iConverter->OpenL(KListFile); break;
case 4: iConverter->OpenL(KLogsFile); break;
case 5: iConverter->OpenL(KSetFile); break;
case 6: iConverter->OpenL(KHelpFile);
}
CActiveScheduler::Start();
}
}

CPNGContainer::CPNGContainer() : iConvertState(EConvertStateNull)
{ /* no implementation */ }

// Destructor
CPNGContainer::~CPNGContainer()
{
delete iConverter; iConverter = NULL;
delete iImageBits[KImgID]; iImageBits[KImgID] = NULL;
}

void CPNGContainer::Draw(const TRect& aRect) const
{
CWindowGc& gc = SystemGc();
gc.Clear( aRect );
if (iConvertState == EConvertStateReady)
{
gc.BitBlt(TPoint(0,0),iImageBits[0]);
gc.BitBlt(TPoint(10,30),iImageBits[1]);
}
}

void CPNGContainer::MiuoOpenComplete(TInt aError)
{
if (aError == KErrNone)
{
TFrameInfo frameInfo;
iConverter->FrameInfo(KFrameIndex,frameInfo);

//Create a bitmap based on the size of the pic
TInt err = iImageBits[CurImg]->Create(frameInfo.iOverallSizeInPixels,KDeviceColourDepth);
if (err == KErrNone)
{ //Convert the pic into a bitmap
iConvertState = EConvertStateReady;
iConverter->ConvertL(*iImageBits[CurImg],KFrameIndex); }
}
}

void CPNGContainer::MiuoConvertComplete(TInt aError)
{
if (aError == KErrNone)
{ CActiveScheduler::Stop(); }
DrawNow();
}

void CPNGContainer::MiuoCreateComplete(TInt /*aError*/)
{ /* no implemenmtation */ }

but if I only view iImageBits[0] it works perfectly fine... when I try to run it in debug this error occurs:

Unhandled exception in epoc.exe (FBSCLI.DLL) : 0x0000005 : Access Violation

please help!!! my deadline is 2 day from now!!!!!
please very desperate!!!!!!

I guess that you should better open next file only after the previous one is opened/converted (so probably in MiuoConvertComplete method).
And another thing, I believe that it is really better to use some of the Symbian's arrays to store objects (for example RPointerArray)

[veskola]

Hello,

Yes thats true, there is no sense to try parallel uncompression because device cannot do that in real parallel mode. Obviously you can implement that but it will be as slow as serial uncompression.

The logical mistake on your code is, there should be as many CPNGContainer objects as there is pictures to decrypt. When there is multible CPNGContainer objects there is also multible callback entry points (e.g. MiuoOpenComplete methods)...but forget this.

Instead that complex approax create an array for bitmaps as sopta007 suggest. Place your filenames to static table and start the first decryption like here:

iConverter->OpenL(fileNames[iFileInProgress];

and then something like:

void CPNGContainer::MiuoConvertComplete(TInt aError)
{
if (aError == KErrNone)
{
// TODO: Add image bitmap to array here...

// Test if there is still images to process
if (++iFileInProgress < sizeof(...))
{
iConverter->OpenL(fileNames[iFileInProgress];
}
else
// Now all images are ready and can be used through RPointerArray
<...>
}

Now you are able to add as many filenames desired without need to touch the code, just write those to filenames to the array. And there is no problem to 'know' how many bitmaps should be deleted on destructor.

I'm sorry, I'm a little slow when it comes to this kind of explanation? if it's not to much to ask could you give me an example??? how I could use this:

iConverter->OpenL(fileNames[iFileInProgress];

I'm very sorry to be asking so much!!! but tnx for all the help!!!
