Save canvas white space... about jsignature

[alexm7]

I'm having the same/similar problem when doing the svg output format. If the signature is only at the top or bottom of the signature block (or left or right side for that matter too), then the saved svg only has the height of what was actually used. So, for example, the signature area is 200 px high. The uses signs just in the top 50px. The generated svg is 50 px high. However, I don't know where that 50px is supposed to be relative to the signing line (is it the top, bottom, middle?). That makes it hard to position the generated signature on a signed document printout when I can't get it to show up with the correct vertical alignment relative to signature line in the print preview. Is there a setting to help with this?

Hi - I solved this by editing the jSignature,js - around line 970 you need to set jSignature to load with a single point already created at x = 0 and y = 0 - this sets the top left corner of the canvas and hence the 0 reference point:

// setting up new dataEngine
data = [
{  x : [0]  , y : [0] } 
]

This will break the undo function, I believe. That's my next bug run, but probably this is not possible using this hack.

when we add this code then we get only top and right cordinates but we need to find all cordinates
