[tex4ht] How to make tex4ht process .png files with scale option for \includegraphics?

[Jaroslav Sobota]

As far as I understand, you have to generate bounding box file (.bb) for 
each PNG image. Use "ebb image.png" command on your command line prompt. 
Ebb.exe is part of ghostcript. Then you will get rid of the "Cannot 
determine size of graphic..." error.

The quality of resulting images is determined by parameters of convert 
command in the <convert> section of the tex4ht.env file, namely e.g. 
"-density 110x110"

With kind regards,
Jaroslav Sobota
