GDI+

[byte-one]

I will test GDI+ as described in:
http://forums.fivetechsupport.com/viewtopic.php?p=63850
But many errors are shown!
Antonio, please test your example..

[Antonio Linares]

Günther,

That example requires to compile using C++ mode. Add -P in samples\buildh.bat :

%bcdir%\bin\bcc32 -M -c -P @b32.bc

also you have to add this line to the example:

Code: Select all  Expand view

#include <hbapi.h>
#include <windows.h>
#include <Gdiplus.h>

using namespace Gdiplus;  // this one!

GdiplusStartupInput gdiplusStartupInput;
ULONG_PTR  

And you have to link gdiplus.lib

With those changes it properly builds

Thanks Antonio!
I found, fivewin should make some substantially routines (lines, rectangles, ellipses, etc.) also with GDI+ as standard! The quality from graphics are much better with antialiasing and so on.

[Antonio Linares]

Günther,

Unless there is a real need for it, my understanding is that GDI+ is an important overload for an application and thus we should avoid it.

I may be wrong, as I have never performed speed tests about this, but I think that a simple API function has to perform much faster that calling a whole OLE objects layer

Also, the less our applications depend from external modules (DLLs, OLE, etc) the more robust applications that we get. FWH applications run on all Windows, have no need for lots of DLLs (like VB i.e.) and that means rock solid apps

Antonio, you are right!
But I will do some tests with GDI+ and report here.
Greetings from Austria.
Antonio, if you visit Otto, please inform me also. My home are only 100km far from Otto!

[Antonio Linares]

Günther,

Surely we will meet very soon!

[byte-one]

Antonio, this are great news!!

For the C-wrapper-routines i write for GDI+ :
Where are the function HB_ISNUM()? I found only ISNUM(). The same?

[Antonio Linares]

Its the same function, for Harbour HB_ISNUM() and for xHarbour ISNUM()

Mr. byte-one,

would do you like to see mrftools.lib (espectaculars effeccts) from antolin ?

Gunther,

Would you mind to share its source code ?

I am writting this from an iPad so no way to run the Windows EXE but I can review its source code

[byte-one]

Antonio, yes, i send to you the code if it ok!
But at moment i need your help:
xharbour-parameter array {{x,y},{x,y},....} to c++-array with same structur

[Bayron]

Nice painting effects...

Antonio so you can see Günther's program:



EDITED:
App is EXE self contained, 1.34 MB and it runs smoothly on a Core i5 with 4MB Ram

[Antonio Linares]

Antonio, yes, i send to you the code if it ok!
But at moment i need your help:
xharbour-parameter array {{x,y},{x,y},....} to c++-array with same structur

Günther,

How many elements the array has ? Is it known in advance ?

[byte-one]

Antonio,

How many elements the array has ? Is it known in advance ?

This are coordinate-points {{x,y},{x,y},....} nested in a array and the quantity from this points are known from side of (x)harbour.
Release from memory after???
