LibreOfficeDraw: Latex system architecture drawing tool in Ubuntu

For the Latex system architecture drawing tool in Ubuntu, I use LibreOfficeDraw. Taking Springer as an example, if the width of the A4 paper is 21 cm and the margin is 4.4 cm, the width of the image should be 21-(4.4*2) = 12.2 cm, for the sake of beauty and insurance, set it to 12 cm. Therefore, we can create a 12 cm * 12cm drawing area. As shown in: it is best to set the margins.
