Why wouldn't you use this?

FreeImage(temp)

Because FreeImage needs the image number (#Image) not the handle (*Image) as a parameter, isn't it?

Code: Select all

ImageID = CreateImage(0, 32, 32)
Debug ImageID
Debug ImageID(0)
FreeImage(0)

Debug ""

ImageAny = CreateImage(#PB_Any, 32, 32)
Debug ImageAny
Debug ImageID(ImageAny)
FreeImage(ImageAny)

#PB_Any does not return the image handle. it returns a pointer to the image object, inside a pb-internal image list. a static number (0-XXXX) is an index to the image object, inside a pb-internal image array.

Thanks, so everything is correct and fine - just got really nervous because of the high values (expected, the next 'free' number would be chosen)

...

...but when comparing multiple pointers and numbers, the difference it obvisously:

Code: Select all

For i=1 To 10
	Debug CreateImage(i,1<<i,1<<i)
Next i

Debug ""

For i=1 To 10
	Debug CreateImage(#PB_Any,1<<i,1<<i)
Next i
