TMSFMXSignatureCapture component


I have a problem with the TMSFMXSignatureCapture component, when reading signatures made with an android tablet,

if i save the signature in jpg or bmp file,if i want to open it on a PC, I see a black rectangle,

if i save the signature in a blob field, it is unreadable on a PC and also with cystal report printing.

when I save the signature, I activate the compatibility mode VCL but it changes nothing.

if I use the component TMSSignatureCapture It is possible read the signature on windows PC,

but other components give a "bitmap invalid" message, and crystal report displays a black square.

How to correctly read the signatures on windows PC, saved in a blob field by an android application.
