BGRABitmapLibrary (.dll and so on...)

[lainz]

In the BGRA-Controls package there is a project called "bgra_pascalscript_library" that compiles bgrabitmap.dll (and in other os's with different extensions..).

Important things:

• It uses bgrapascalscript.pas: basically we reuse the code that is being used in the bgrabitmap implementation for pascal script because it works the same way.
• For that is named bgra_pascalscript_library. But it makes a library called just "bgrabitmap".

Current stage:
* Tested with Visual Studio C# 2013. The unit with the classes is available in the subdirectory "c#".
* Tested with Lazarus. The unit with the functions is available in the subdirectory "pascal".
* Now is compatible as Java library.

Hi! It looks great.

There was a small thing when trying to compile:
bgra_pascalscript_library.lpr(115,37) Error: Identifier not found "bgra_DestroyAll"

Ok. It is using bgrapascalscript.pas that is in the root directory of bgracontrols, so maybe you have an outdated version or I've commited it wrong?

Edit: It's my fault. I'm updating the repository now.

[circular]

It is not obvious to know what we commit or not, so it is useful to have someone else to check out what we do 

[lainz]

Yes it is.

Well I think I finished the first step. Now C# and pascal headers has all the filters ready to use. Just compile the library, add the bgrabitmap.cs in your C# ide, bgrabitmaplibrary.pas in lazarus, put the dll in the same folder as the executable and it should work.

Now the thing is adding the drawing stuff, that is a lot!

Also Fred vS has a question about how we can use fpGUI instead of LCL in a Library? It is configurable in some way or is not possible? Reaching the fpgui part of BGRABitmap...

Also Fred vS has a question about how we can use fpGUI instead of LCL in a Library?

Hum, the question was not to use fpGUI instead of LCL but not to use LCL. 
Also, for your library i see more something nude, without any widgetset (LCL, fpGUI or whatever) , like Agg library.

Fre;D

Ah, well there some progress towards have no LCL, but it is not there yet. However I think it would be possible.

[Fred vS]

However I think it would be possible.

Hum, i think that nothing is impossible for BGRABitmap 

[circular]

Ahah 

By the way, does the linux version compile now for you?

I will jump into it this night.

Write-you later.

Have try to compile bgra_pascalscript_library.lpr on Linux Mint 64 bit =>

../bgrabitmap/bgrapath.pas(2535,5) Fatal: Internal error 2009112601

Hum, not any idea what is error 2009112601 

bgrapath.pas(2535,5) =>

Code: [Select]

procedure TBGRAPath.arc(const arcDef: TArcDef);
var transformedArc: TArcElement;
begin
... 
    SetLastCoord(ArcEndPoint(arcDef)); // here error
  end;
end;           
Fre;D

[Fred vS]

OK, to go further i commented =>

Code: [Select]

// SetLastCoord(ArcEndPoint(arcDef));
Now i have that error =>

../bgrabitmap/bgrapath.pas(2595,32) Error: Call by var for arg no. 1 has to match exactly: Got "LongInt" expected "Int64"

/bgrabitmap/bgrapath.pas(2595,32)  =>

Code: [Select]

  until not GoToNextElement(pos);   
OK, to go further i changed =>

Code: [Select]

var
pos : int64;
Now it compiles but at linking i have that error =>

/usr/bin/ld: .../bgra-controls-code-86/lib/x86_64-linux/2.6.4/bgrapascalscript.o: relocation R_X86_64_32S against `U_BGRAPASCALSCRIPT_BITMAPARRAY' can not be used when making a shared object; recompile with -fPIC

Adding -fPIC compiler-parameter did not help...

Fre;D

[Fred vS]

Sorry to monopolize 

   

../bgrabitmap/bgrapath.pas(2535,5) Fatal: Internal error 2009112601

=>   SetLastCoord(ArcEndPoint(arcDef)); // here error

Hum, not any idea what is error 2009112601 
 

=> It seems to be something wrong with Inline

Code: [Select]

function SetLastCoord(ACoord: TPointF): TPointF; inline; => gives error.

But

Code: [Select]

function SetLastCoord(ACoord: TPointF): TPointF; => gives NO error.

PS : But still error after compil => at linking 

[circular]

Yes, "pos" variable is in fact IntPtr. You can download the latest version if you like to have this fix.

Others erros could be related to the version of the compiler?

[Fred vS]

Others erros could be related to the version of the compiler?

Hmmm, for function SetLastCoord(ACoord: TPointF): TPointF; inline; , maybe, i use fpc 2.6.4.

For error while linking i could try with fpc 3.0.1, maybe it is fixed (but for that updated-LazUtils is needed...).

Hum, LCL dependencies do it harder for the linker.

You can download the latest version if you like to have this fix.

Downloaded bgrabitmap8.4 one hour ago => same error...
