Multiple export of ready-made DXF to JPG miniatures

[mihkov]

The main part of the macro is the SaveJPGfromDXF function, which receives an array of full paths of DXF files and saves them back as JPG images (with the specified parameters).
It is understood that the file paths could be obtained in different ways. For example, you can organize multiple selection of DXF files from a folder using the Excel library, since SW does not know how to do this (I don’t know about this).
For example, in the main Sub, a static array with paths was simply created to test the operation of the function. Everything else is in the comments in the code.
