cannot save image with white background

I can't manage to save my image with white background. I generated the image by using isocaps and isosurface. I used also contours and patch.

I tried the following: set(gcf,'invertHardcopy','off') print -djpeg thefilename.jpg print -dbmp thefilename.jpg

I also tried: [X,map]=getframe; >> imwrite(X,map,'thefilename.jpg')

Then I tried: saveas(gcf,'thefilename.png')

In all the cases I always get black background. Could somebody give a hint? Thanks in advance Isabella please find enclosed the image. I am using Matlab R2011b 32 bit 7.13.564

Have you tried export_fig?

Dear Image Analyst, thank you for your answer. I used export_fig, and the background is now white, but the surfaces lost their transparency. Please find enclosed the pdf file with the resulting image. Do you know how I can improve the result? Thank you for your time, Isabella

Contact Oliver - he wrote export_fig. He may say change rendering method and try again.

Dear Image Analyst, I solved my problem by using export_fig, but I first had to force matlab to a white background. to do this, I went to :

matlab main menu->file--> figure copy template--> Copy options

I checked Force white background.

After that, I generated the image as: export_fig('tmp.png','-png') and it worked now very well Thank you so much for the hint! I will accept your answer

Glad you figured it out - looks tricky. Sometimes even when using export_fig, it can be tricky, but it's almost always better than attempting to use the standard functions on your own.

Hi, you can use set(gcf, 'Color', 'w') before using the export_fig command to have a white background in your figure.
