expand image size

[Lars Damgaard]

Hi,

I want to expand my images with a black rectangle so that I can print the overlay (a timestamp) there where it does not interfere with my image.
The only solution I found so far is to create a new larger black image and then use imageCalculator("add...) to add the original image onto that. However, this solution does not give me any choice in the relative positions of the original and the black image, so the black area (that stays black because it has no corresponding pixels to add in the original image) is always positioned below the image.
Is there not a way to expand an image in a user-defined direction? Or a way to 'stitch' one (black) picture onto one of the sides of another image?

Thanks for any help, Lars

Hi Lars,

You can use the Image>Adjust>Canvas Size... command.
Sincerely,
Jerome.
