So the rectangles aren't centered on the page? If they aren't centered on the page, then where are they? Are they in the NW corner? Are they against the edge as in this example, or are they offset as in the other example?

If the outer rectangle is 10mmx10mm and the inner rectangle is 6mmx6mm, am I to assume the diagram is wrong, because that says it's 3mmx3mm. What do any of the numbers in the CSV file have to do with these new numbers?

How do millimeters relate to anything in image coordinates in pixels? We still don't know how big the image is.

Again, if you want 4 rectangles, then which coordinates correspond to which rectangles? If each pair of rows in the CSV file correspond to an inner and outer rectangle respectively, then the second pair is in opposite order. Are the rectangles even drawn in pairs in separate images? Is there something else that involves all 4 rectangles in one image?

Or is each row in the CSV representative of a pair of rectangles? (i.e. [10 6] denotes a 10x10 black rectangle and a 6x6 white rectangle). Is it safe to assume that these are indeed supposed to be squares?

Size of a printed image when print() is used, depends upon the figure PaperPosition properties.

DGM 2022-7-26

Every time I've tried to do that, it seems that the PaperPosition is controlling the figure position, but the image is much smaller, since the axes has padding. I don't think I ever managed to wrangle a means to do it programmatically that actually worked consistently. I can get it to work using the GUI, but I'm assuming a programmatic approach is desired.
