[Conversion Plugin] KFX Input

For example, given 1238 x 1800 images in original artwork, the page dimensions in the PDF wind up as 17.19 x 25 inches, as if the images had 72 PPI property. In this case 300 PPI would derive 4.13 x 6 inches, which is the physical page size of the printed comic.

The plugin does not currently set the DPI when creating PDF pages. It appears that the default value is 72 for the PDF creation software it uses.

Amazon comic format does not specify actual page sizes since that is not generally relavant for an e-reader. However the underlying image files may sometimes have DPI metadata. I will change plugin to use that when available and otherwise default to 300 dpi.

How that works out will depend on whether or not the underlying images contain reasonable DPI values. I will do some testing before releasing the change.

In my spot checking, the image DPI does not seem to matter (when I import folder of image files to Kindle Create).

When importing PDF to KC, image objects therein do not have DPI property, and I assume KC is assigning one when it imports these.

Before importing PDF to KC, I take care that the page sizes are accurate so that KC doesn't scale the images up (as recounted earlier in this thread).
