MemoryblockRGBAtoPictureMBS(dest as picture, source as memoryblock, offset as Integer, width as Integer, height as Integer, FlipVertically as boolean=false) as picture

// Create a picture with mask:
dim p as Picture = LogoMBS(200)
dim g as Graphics = p.mask.Graphics

g.ForeColor = &cFFFFFF
g.FillRect 0,0,g.Width,g.Height

g.ForeColor = &c000000
g.Filloval 0,0,g.Width,g.Height

// convert to memoryblock
dim m as new MemoryBlock(4 * p.Width * p.Height)

if p.CopyRGBAtoMemoryblockMBS(m, 0, p.Mask) then
  // convert back
  Backdrop = MemoryblockRGBAtoPictureMBS(m, 0, p.Width, p.Height)
  
  break // look into memoryblock with debugger
end if

Returns nil on any error.
source should not be nil.
offset should be 0 or bigger and is the start position in the memoryblock.

The function will crash if the memoryblock is too small. Needs width*height*4 bytes in the memoryblock.

In the dest picture parameter you can provide a picture to draw in. If the picture is no big enough or nil, a new one is created.

If FlipVertically is true the image is flipped. New in version 9.4.

Does not access the mask inside the image!
Data is copied from memory block to the new picture, not referenced.
