Transparency replaced with white

[johnpturner8]

When processing a PNG with transparency, the transparency is removed and replaced with a white background, even when the mimeType is set to PNG in the config.

This seems to be caused by the fix for #42, PNGs retain their transparency in the previous version.

@johnpturner8 ah good catch, let me see about plugging this bug.

Got a fix in place, will push out a new version to NPM shortly.

Transparent PNG => mimeType: 'image/png'

Transparent PNG => mimeType: 'image/jpeg'

JPEG => mimeType: 'image/jpeg'

Hi,

I'm using 2.4.1 and still have this issue. It adds a white background to PNG's with transparent background @ericnograles.

@jz222 huh strange, pretty sure I tested it. Did you set the mimeType to image/png? By default, if nothing is specified, the library assumes image/jpeg which will give your PNG a white background by design.
