In thinking about the best way to move forward the best of image3 addon
to 64 bit and J7 it seems to me that using OS resources would be
preferred over porting the image3 dll source to 64 bit. In the platimg
addon I see that Oleg managed that nicely in J6 32. I presume this has
also been done in J7 based on the J7 api/gdi addon. Any pointers to
where I should look for examples to that?
In particular, Oleg uses
GdipBitmapLockBits=: 'gdiplus GdipBitmapLockBits> i i i i i *i ' cdi
while the API/GDI uses
GdipBitmapLockBits=: 'gdiplus GdipBitmapLockBits i x *i i i *x'&cd
What do the x's mean.
In J6 64bit neither work (using gdiplus.ijs I get furthest), further still with
adding oleg's version above, but the actual memory data read fails
z=. (h,w)$memr p,0,(w*h),4
|domain error: memr
| z=.(h,w)$ memr p,0,(w*h),4
|[-17] c:\data\io.ijs
Ideas?
Best, Cliff
