As I understood,
GDIP_IMAGEFROMFILE( cFile, .T. )
can now be used to load an image without FREEIMAGE.DLL. Is there something similar to SAVE an image?

Enrico,
Manuel (Mastintin) is our GDI master. Lets see what he can tell us.
GDIP_IMAGEFROMFILE( cFile, .T. ) return classic hbitmap
Seria posible no usar freeimage.dll en la mayoria de los formatos imagenes comunes .
Funciona correcto con jpg, gif,tif,png, bmp , ico
Mas facil es unsar la clase creada a tal efecto y que se encuentra en c:\fwh\sources\tgdiplus.prg ...
Para grabar una imagen seria lago asi ...

local cImage := "image.bmp"
local
local oGdi := GDIBmp():new( cImage )
oGdi:save( "imagenfinal.png")
oGdi:end()Thank you. I'm going to experiment with it.

Ok, it's working, thank you.

These are a couple of functions I wrote:

Enrico, GDIPLUSIMAGESAVE function transform asitowide in your code ... is not necessary ansitowide functions
std::string str = hb_parc(2) ;
std::wstring wstr (str.begin(), str.end());
LPWSTR file = (LPWSTR) wstr.c_str();
I've already tried: it doesn't work without ANSITOWIDE().

Do I have to use
instead to release the image, right? Can you confirm this?

Yes. Enrico use
GDIP_DELETEIMAGE( hImg ) // release pointer to gdi+ image object
instead
DELETEOBJECT( hImg ) // release pointer to "classic" image object
Thank you. Do you have any news for the quality of saved GIF?
Sample:
EMG
Sample:
#include "Fivewin.ch"
FUNCTION MAIN()
LOCAL cSrcImage := "c:\fwh\bitmaps\magic.bmp"
LOCAL cDstImage := "magic.gif"
LOCAL oGdi := GDIBmp():New( cSrcImage )
oGdi:Save( cDstImage )
oGdi:End()
RETURN NILEMG
Enrico . No more news.
to solve the problem, we first have to develop code for octree algorithm and my c ++ does not go that far. I have c ++ code that is done but do not get removed compile errors.
However, the GIF format is licensed for use and is overwhelmed by png or tif.
If anyone is encouraged... your code is this ....

Do you have QColorQuantizer.h?
