Trouble with image colors

[jarvis24]

Take a look at the same picture converted to a 256 color BMP by IrfanView (a freeware program from www.irfanview.com). It does a much better job than Paint. However, you may simply have a system that stores display information separately for each monitor resolution. Try manually setting your monitor to your target resolution (e.g., 800x600, 1024x768, etc.) and see if that target res is set to run at 256 colours. If so, bump it up to 24 or 32 bit (i.e., millions of colors). Then try running the session from that or any other resolution and see if it helps. You might also be running the session at a higher resolution on your machine that can't handle millions of colours. If that's a possibility, try running the session at a lower res like 1024x768.

Hi,

My images also seem washed out on a specific computer we are running our study on. I double checked by opening the actual BMP file (saved from PPT) and there the images look perfect. As soon as I run the file in DirectRT the images look washed out/over exposed (e.g., too bright). I checked my screen resolution settings and the DirectRT style settings and everything seems fine.

I would appreciate any extra suggestions you may have.

Can you send me one of these images and a copy of your style (.drt) file?

hi

I am having a similar problem. My bmp images are orginally black and white, and when viewed in image viewing or editing software (e.g. photoshop, paint, ifranview) they appear fine. However, when I attempt to display them in DirectRT, they appear blotchy in some parts of the image, and other colours (e.g. red and green) become visible. I have tried various monitor resolutions and resizing the images, but no success. Attached is one of the files.

Can you post or send me a copy of the style (.drt) file and input file you are using and also a copy of your system diagnostics via dxdiag? Instructuctions for the latter are here: www.empirisoft.com/Support/showthread.php?t=75

Will take a look and see if I can tell what's up with it.

Thanks for your time. Here are the attached files.

Your dxdiag file looks fine although the driver for your video card is pretty old (2000) you may want to try an update if you can find one.

Some questions..

Does the same effect occur for any of the DirectRT samples that use images, e.g.,

C:\DirectRT\Samples\4 applications\image priming\implicit.csv

If it's unique to this study you are running, I'd be curious to know if the images from the sample above look washed out when used in your study. Or, if the images in your study look washed out when used in that sample.
