Hi

There are any way to load a .png file stored in a resource (rc) file and display it using drawalpha() ?

Thanks in advance,

Best regards,

Hello,

I don't know any resource-editors can save a PNG-file to resource.
The solution, I'm working with ( Resource-Builder ), can handle JPG's :

The Graphic-part of the Help-file :

Advanced features in working with graphic resources
Resource Builder allows you to work with images in the JPEG format as easily as with standard BMP images. Support for images with any size and colors count allows using Resource Builder as a replacement for Borland Resource Workshop or Image Editor, which unable to support "quality" images in projects. Moreover, the graphic editor of the program allows you to process images with the help of various filters making it no worse than serious graphic packages.

Uwe

Hi Uwe,

Borland Resource Workshop can do it:

#define RT_RCDATA 10
nId RT_RCDATA NONDISCARDABLE "imagem.png"

My question is another: How to load it and have a valid handle, maybe something like:

hBitmap = LoadBitmap( GetResources(), cResName )


Thanks and best regards,

Toninho.

Toninho,

Please review FWH\source\winapi\resource.c function cResToStr( cnResName, cType ) --> cResourceBytes

I tried this test

PROCEDURE Main()
LOCAL cDatiPng
cDatiPng := cResToStr("DASH_HOME","PNG")
IF !Empty(cDatiPng)
hb_MemoWrit("immagine_estratta.png", cDatiPng)
? "PNG estratto con successo!"
ELSE
? "Errore: risorsa non trovata."
ENDIF
RETURN

and not found the resource why ?
