Is there any way to save an image that has been drawn onto a TCanvas?
(like the opposite of DrawImage)

I am trying to capture a customers signature on my mobile app.

I have yet to look at this but will shortly want to do the same

I have come across another problem with using TPaint for this - on a
mobile when you try and draw on the TPaint control is slides around
instead of drawing on it!

Is there any way of disabling this feature?

This won't be possible until the EWB framework is "touch-event-sensitive".

Not currently, no.  There is some extended functionality in various browsers
that allows for raw pixel access, but EWB doesn't support that right now.

Hi Mark,

I am also looking at this component to see if I can interface it to EWB.

This is what I used in my old ASP.NET application and it works great.
Maybe if enough of us show an interest in it he will write the link into
EWb for us

Okay, this is not a massive problem as I can capture the drawing points
into an array as I go along and store them myself.

Any idea how far down the line this is going to be as I envisage needing
to capture signatures in about 2 to 3 months time.....

Chris,

It will probably show up in 1.03.  It's the last missing piece for mobile
(besides a mobile-specific theme).
