Google had pointed me to that, and I admit that I had failed to understand the model. Partly because my image is too big to go in one string. 

My bitmap program outputs:

/RawData currentfile /ASCIIHexDecode filter def
/Data RawData << >> /DCTDecode filter def
261.00 189.00 scale
/DeviceRGB setcolorspace
{ << /ImageType 1
     /Width 1091
     /Height 791
     /ImageMatrix [ 1091 0 0 -791 0 791 ]
     /DataSource Data
     /BitsPerComponent 8
     /Decode [0 1 0 1 0 1]
 >> image
 Data closefile
 RawData flushfile
 showpage
 restore
} exec
FFD8FFE000104A46494600010100004800480000FFE100404578696600004D

I don’t understand the reading mechanism for the data. 

Can I just 
/RawData currentfile /ASCIIHexDecode filter def
/Data RawData << >> /DCTDecode filter def
FFD8FFE000104A46494600010100004800480000FFE100404578696600004D
…
…
…
%EOF 

to store the image data in Data? Could I then 

<< /ImageType 1
     /Width 1091
     /Height 791
     /ImageMatrix [ 1091 0 0 -791 0 791 ]
     /DataSource Data
     /BitsPerComponent 8
     /Decode [0 1 0 1 0 1]
 >> image

to paint? Or have I misunderstood the model. 

Thank you.
