Removing the white square in an otherwise clear bitmap image.

[iMatt]

What's the correct method of removing the white square around a TIFF bitmap image within Affinity Designer or Publisher? Thanks in advance.

White square you mean white line? Decreasing image size? (menu File, Document Setup, Dimensions, Rasterize & Trim).

This is what I mean. The image is a TIFF bitmap. I wish the white square to disappear leaving just the black image. I was told this some time ago but forgot how!!!

What about the Crop tool?

Edit: Argh sorry, I see you are in Designer. You could try the Art Board Tool.

Which part?

• The whole canvas?
• The brown rectangle?
• The white rectangle with the black pattern?

I'd be much more interested to see your expanded Layers panel, rather than an irrelevant collection of brushes and effects…

If you have Photo you could edit the image in that by using; File > Edit in Photo...  And once in Photo go to; Filters > Colours > Erase White Paper and then send it back to Designer.
A quick and dirty method might be to set the Layer’s blend mode to Multiply. Any content under white areas would then show through.

I'd have thought it obvious! How can I mean the whole canvas! And how can it be the brown rectangale when i mentioned the BLACK image?

Ok, will give this a go a bit later. Thanks.

THANK YOU! It worked like a charm. Will make a screenshot of your helpful reply in case I ever forget!

In order to make it easier for others to understand next time, it is a matter of deleting the background of the image.
Whether it is a square or some other shape is completely irrelevant.
