Dear ConTeXt users, I am making a presentation using ConTeXt, and wish to use some plain images. I am running into some trouble, especially with the background colour of the image, which I wish to force. Here is some information: 1. I make the image using Dia, and export it. 2. I include the EPS directly, and Acrobat doesn't like it. 3. I epstopdf the images, they come otu well, except that they are transparent and the images with black text and lines looks bad on my dark background presentation. I partially worked around the problem by using background=screen in my \useexternalfigure calls. However, I have a combination image, where the second image comes without the white filled background. Could you please tell me a way to force the background colour of my images to white? I really don't want to convert it to PNG or something, since PNG doesn't look nice after scaling, does it? :-) Thanks in advance. And FYI: Version: Debian package: CtxTools | context version: 2007.04.17 12:51 (/usr/share/texmf/tex/context/base/context.tex) CtxTools | context version: 2007.04.17 12:51 (/usr/share/texmf/tex/context/base/cont-new.tex) Kumar -- Kumar Appaiah, 458, Jamuna Hostel, Indian Institute of Technology Madras, Chennai - 600 036

Hi Kumar, you are not restricted to a gray background in your figures, you can also use colors. \externalfigure[...][background=color,backgroundcolor=white] Wolfgang

I seriously don't know why I didn't try it... it works wonderfully!
Thanks a lot! :-)

Hi Kumar, you can also use background=screen but have to set backgroundscreen too, \externalfigure[...][background=screen,backgroundscreen=1] create also a white background. Greetings Wolfgang
