History for managing signatures (history as of 17/11/2010 16:14:25)

 

Modern scanning software allows the user to scan at a resolution of literally millions of colours, so we need to set specific image criteria when uploading signatures, to prevent the e-Cert website becoming overloaded with incredibly large signature image files.
 
Therefore, images must be scanned to adhere to the following criteria:
 
-          Microsoft .BMP format
-          Maximum size - half inch high x two inches wide
-          Black and White (1-bit)
-          300 dpi
-          Maximum size 30kb
 
You should be able to achieve these results within your scanning software; you just need to choose the correct methods of scanning: 
 
Microsoft .BMP format: When saving the scanned image, choose to save it in this format.
 
Maximum size - half inch high x two inches wide: When you physically sign your specimen signature onto blank paper, ensure that the signature does not exceed this size. When you then scan the image ensure that the signature is scanned at full size, and then crop off any surrounding superfluous image that surrounds the signature (therefore scanning just the signature itself and not the whole page).
 
Black and White (1 bit): This will vary between different scanning applications, but generally you should be looking for the lowest quality scanning option (i.e. text or fax quality, instead of black and white or full colour photo quality).
 
300 dpi: Once again, this will vary between different scanning packages, but generally this option should either be selectable at the time of scanning, or it will be set up as the default scanning resolution for the scanner. Either way it needs to be set to 300 dpi when scanning signatures for upload into e-Cert.
 
Maximum Size 30kb: If all of the above requirements have been fulfilled, then the image should not exceed 30kb in size.
 
If you have a paint package (i.e. Paint Shop Pro), you should also find that all of the above results can be achieved through editing the image post scanning if needed.
