Black images


	I seem to be having a problem running my color quickcam. I  
am using one of the earlier versions of the color quickcam driver  
for Linux. My operating system is OpenStep for mach, but there was  
very little hacking involved in porting the code.

	I am currently outputing a ppm file (as always) and then  
viewing it. All I see is a black image and occassionally some green  
splattered around toward the bottom of the image.

Any suggestions as to what the probable cause maybe and how I may  
go about fixing it?
