Graphics, Figures & Tables ⇒ Help with beamer images

[pmitchell12]

Hello, please forgive me if this is posted in the wrong section, this is my first time posting on this forum. I'm making my fourth presentation with beamer, but have encountered something that has not happened before. I am using a dark blue/purple background with an off-white accent colour for my text. I have a series of pdf images to insert, all of which are black text on white background. However upon insertion, some images insert as black text on dark background (the white background goes away) while otehr images appear as white on my dark background (the colours seem to have inverted). I actually like this inversion better, and was wondering how to get it to work for all of the images?

Thanks in advance for help, greatly appreciated!

Unless the code you're using to insert them is different in the different cases (which I'd guess you'd tell us!), I imagine the difference is that some of these included images use a transparent background and some use a white background. The difference would then be in the images themselves, and you would just need to make sure you made them that way to begin with. Without knowing how you made these PDFs to begin with (or where you got them), I'm not sure more can be said than just that.

Thanks for replying!

They were all made in Microsoft Publisher then printed to pdf. I feel like that might be the difference as I used Win2PDF for some then AdobePDF for others. Thanks for your insight!
