Dear user,

You can use the Color Replace filter to replace a shade of color with your desired color.

Is it possible to bleach art canvas white? Has anyone ever tried to bleach canvas so that it is white rather than its natural colour. Any tips here would be appreciated.

Hello,

There is no special function for this task but you can combine a few filters to obtain the desired effect. To transform the canvas you could use: Resize and Crop filters. To add a white background you can use the Border filter.

You can try BatchPhoto for free and see if it solves your problem. Download from:

Hi,

I'd like to batch transform all my pics to be square. Can I do this? I dont want the aspect ratio to change, just add a white background as necessary.
