I meant which version of viewer specifically are you running? Goto

Becuase the 64K limitation is on the hotsync protocol, not on plucker.
According to the specifications the max size for a single record is
64K. To plucker, a record can be defined as one page of text, or a
single image.

This is the same reason as to why people complain when their large
html pages are split up into multiple plucker pages.

There's no function on the palm called WinDrawPng(), but there is one
called WinDrawBitmap() In order to do this properly, we need to
convert the png format into the tbmp format before it can be displayed
using the native-palm API.

true.

Since you've never programmed anything like this before, you
underestimate the work required to convert from format A into format B
transparently.  Believe me, it's not simple.

Either way, it'll probably be along time before this png support makes
the light of day. Too much work, and I've already promised too many
other things already.

Sure,.. I'm also going to re-enable it for OS5
