Reply To: Image logo get distorted only in mobi file

Hi…
I am here again, it seems I solve the problem, but it is not completely true.
I get the logo non distorted in kindle, but the logo is text in black with the white background. I exported from inDesign in PNG 300 dpi and in iBooks in day view is OK, in night view the logo disappears because is a black text on black screen (I can accept this, not a lot of people will read the logo in night mode)
The problem is always in Kindle, while I convert the EPUB in MOBI I get the logo OK in day view (White screen) but in night mode (black or sepia screen) I can see the withe box around the logo, the exact dimension of the text box I do have in inDesign. It seems Kindle does not support transparency? is it true?
i try to reduce the text box in order having the minimum box for the text double clicking on the handle of the box in inDesign, but at the time I do this and re-export I get in Kindle the image distorted again.
Really I don’t know how to do.
