OK, I took ancalex's progress with copying those temporary files to the source file's directory and tried to eliminate those two extra parameters recently added for userTmpDir and docTmpDir as those are known within the .js script. The results are posted below in any2IMP v0.1.2. The .zip includes the source .au3, compiled .exe and modified .js script.
Basically, I used the variable
project.SourceFile(0) to provide me with the filename of the first spine entry (zero-based index) in the .opf; which will usually contain the source (html) .tmp file I need to modify before the .imp conversion takes place.
This file can then be opened and various replace operations can be applied to remove inconsistencies or add functionality. I prefer small margins, big pictures, and use of the default fonts and will develop some replace regex once I brush up on how jscript implements these.
