TCanvas - Save Image |
Wed, Jul 10 2013 3:55 AM | Permanent Link |
Chris Holland SEC Solutions Ltd. Team Elevate | 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. -- Chris Holland [Team Elevate] |

Chris Holland SEC Solutions Ltd. Team Elevate | 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?

There is some extended functionality in various browsers that allows for raw pixel access, but EWB doesn't support that right now. Tim Young Elevate Software www.elevatesoft.com |

Chris Holland SEC Solutions Ltd. Team Elevate | Hi Mark,
I am also looking at this component to see if I can interface it to EWB. http://supersignature.com/ 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 Chris Holland [Team Elevate] On 10/07/2013 12:42, Mark Brooks wrote: >>> 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 > |

Chris Holland SEC Solutions Ltd. Team Elevate | 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.

Chris Holland SEC Solutions Ltd. Team Elevate | 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.....

<< 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..... >> It will probably show up in 1.03. It's the last missing piece for mobile (besides a mobile-specific theme). Tim Young Elevate Software www.elevatesoft.com |
