How to change the background of a picture/logo to transparent if it was not saved as an SVG
Hi,
My colleagues and I are developing a website for our organisation. The logo for our organisation is two colours: blue on a white background and was developed by an untraceable someone three years ago. The only copy of our logo that I have is as an image in a MS word document.
We are currently working on our website as a series of linked powerpoint slides, each representing a page and with the logo appearing at the top. The background to these pages is a greenish blue colour. The logo looks clunky and unprofesssional because we cannot separate it from its square white background.
We would like to make the background transparent (or remove it altogether if that was possible). We might also want to change the blue colour of our logo to something else that provides more contrast against the greenish blue background of the web pages.
I have used inkscape before to separate out components and re-colour them: problem is it was quite some time ago and I can't remember how I did it. Furthermore, when I open the logo in inkscape as a .tif or .png file, inkscape does not seem to differentiate between the white background and the blue logo. There does not seem to be any layering and if I try to ungroup it does nothing. If I try to change the colours via the relevant toolbar, again it does nothing. For example if I click on greyscale there is a brief flash of activity but the image does not change (or the revised image is hiding somewhere and I can't see it).
What would be the best way for me to separate out these two components (background and logo)? Is there a particular format that I could "save picture as" from the MS word document that would allow inkscape to recognise the two components as separate?
Or, if that is not possible because the image is locked in its composite form - is there any way I could use inkscape to re-colour the background as transparent, and re-colour the logo as well?
Many thanks for your help,
Best,
Amy
