Can someone tell me why under PB5.11 encodeimage return properly the address
of memory but under PB5.2 beta always return 0.

If *this\Dbase\QuerytblMachineDiagram(MachineId,@machineDiagram)
If machineDiagram\diagram
ImageNr = CatchImage(#PB_Any,machineDiagram\diagram)
If ImageNr
imaged = CreateImage(#PB_Any,ImageWidth(ImageNr),ImageHeight(ImageNr),24) ;,$FFFFFF)
If imaged
StartDrawing(ImageOutput(imaged))
Box(0,0,ImageWidth(ImageNr),ImageHeight(ImageNr),$FFFFFF)
DrawImage(ImageID(ImageNr),0,0)
StopDrawing()
If imaged
*imgbuffer = EncodeImage(imaged,#PB_ImagePlugin_PNG,#PB_Image_FloydSteinberg,8)
MessageRequester("Test line","Memory : " + Str(*imgbuffer))
If *imgbuffer
DoSomething()
; ShowMemoryViewer(*imgbuffer,MemorySize(*imgbuffer))
EndIf
SetGadgetState(*this\GdgtMachImage,ImageID(imaged))
EndIf
EndIf
EndIf
EndIf
EndIf

Where is your " UsePNGImageEncoder() " ??

already define above the code.
The code run fine using PB5.11. I confirm about it. But under PB5.2 beta 6 and 7 I tested
the result always 0. I mean encode image always return 0.

Please post a "working" snippet which demonstrates the problem and Please use Code Tags.

cheers

here simple test. Under PB5.11 I got and address for *imgbuffer.
But using PB5.2 beta 7 got 0 only.

Forgot to tell. I use PB5.11 and PB_5.2 beta7 OSX 64bit.

returns a memory address on Windows x64 - PB 32 5.2 b7

So the problem is only under OSX when using PB5.2 beta version.
