Code is repeatedly calling image. The first call works wonderfully: bitmap paints; looks good — Bliss was it in that dawn to be alive. Alas subsequent invocations don’t paint anything. What could be wrong? 

I was calling the code via execform, but that’s been simplified to “ShipperLogoForm dup /PaintProc get exec”, where: 

/ShipperLogoForm <<
<< /width 1147  /height 1395 >> begin
	/width width
	/height height
	/BBox [ 0  0  width  height ] readonly
end
	/FormType 1
	/Matrix matrix identmatrix
	/PaintProc
	{
		WithinPage =  % Just to verify that being executed many times—it is!
		begin
		/DeviceRGB setcolorspace
		<<
			/ImageType 1
			/Width width
			/Height height
			/ImageMatrix [1 0 0 -1 0 height]
			/DataSource  Logo_Data
			/BitsPerComponent 8
			/Decode [0 1 0 1 0 1]
		>> image
		end
	} bind
>> readonly def  % /ShipperLogoForm



Please, clues welcomed. First invocation delicious; subsequent paint nothing.
