There is a problem  concerns  the  size of picture block and the quality of picture in the block.
\\ \\ 
When the size of block with picture is smaller then 30 mm (approx. 110 pixels),  the  quality  of  picture  which  contain  lines  of 1 pixel thickness, is deteriorated.
\\ \\ 
As  a  result  of  image  resizing,  the  bulk of pixels of thin lines disappears,  and  the when size  of  block  becomes smaller - the most part of pixels is lost.
\\ \\ 
I  had  tried  to  find solutions for this problem but none of several found  methods of image quality improvement does gave some significant result.
\\ \\ 
Therefore there is a suggestion 
\\ \\ 
1) introduce restriction on minimal size of image block, so they couldn't be resized lesser than certain square
\\ 
2) reproduce sample images with smaller sizes (minimal size of image block)
\\ \\ 
This case samples would be only stretched or increased, therefore it shouldn't be a loss of quality
