    Default Transparent Background

    I'm creating a signature that I can paste in to electronic documents, so I don't have to print, sign, scan, and email things I need to sign. It's been recommended by several sites on the internet to save the signature as a black image with a transparent background. I scanned it at a jpeg image, but don't know how to make the background transparent in Irfanview. Can anyone help?

    Scan your signature again and save it as a GIF or PNG image. These formats can have a transparent background.

    Better solutions are to add your signature to a font using eudcedit.exe or a font editor. Eudcedit.exe is part of Windows, just run it from the Windows Key + R run dialogue. It only produces bitmapped characters, but may be OK. It adds custom characters to the Private Use Area (PUA), which can be used with any installed font by inserting them from Character Map.

    Adding your signature to a fully scalable Truetype Font is the ideal solution. FontCreator or Scanahand is the tool that you need for this job.

    Default Transparent Background

    Ok, I have it as a PNG. But I'm not sure how to select transparent for the background color. And how would I know the background is transparent? The only color in the foreground is black, so the background appears white.

    Hi spthomas,

    When you save your png, click on Show options dialog and there check Save transparent color. You will be prompted to select the transparent color after you click on Save.

    To see something else than black through a transparent color, use another color than black for IrfanView background color.
