No John.

The data set is the same, in the second plot I slightly changed the mleft margin value to have more place for the two grey boxes to the right of the plot
although in the scale nothing formally changed since the scale is rounded to the nearest whole hundred.

John,

you are probably right - but it has no meaning for my purpose. Remember - the JPG raster is - in fact - a pure screenshot of a georeferenced JPG raster image
displayed in the mobile mapping processing software using Snip&Sketch tool. And - as I already said, I changed the value for left margin between two images, which has its influence.

So, the JPG screenshot has nothing to do with the real vector graphics, where all points have real geodetical coordinates. It can hardly be aligned
with vector graphics (points with the real geodetical coordinates). The screenshot depends what you select in the Snip&Sketch.

Here - it serves only for general purposes - approximately in which area was the mobile mapping done and to have something in the background in otherwise white background plot.

Therefore I suggested to add an option in the %pl to load in a georeferenced raster JPG image. It would mean that the real geodetical coordinates would be known
for the top left corner of such image, then there is also specified its pixel size, so every pixel(point) in such image would have its real geodetical coordinates. This could be very well aligned with vector graphic.

Nevertheless, thanks for your observant remarks!

This is a good idea John!

I will include this useful remark somewhere below the plot - thanks!

Martin

P.S. To be clear - the vector points are very precise (their horizontal accuracy is on the level of several centimeters)! So they are accurately displayed in the plot. The term APPROXIMATELY refers to the background
JPG image, when it is loaded to the plot into the background
(due to known reasons).

Thanks John for additional inspiration!

I added the information text regarding the use of JPG picture in the plot
and the text and a complex view of the graphics is demonstrated here:



The text says:

ATTENTION! The use of JPG raster image in the background serves
for information purposes only!
