Dear R users, in my application i can transfer images to R with the help of Rserve. The images come from a java application. When i plot a greyscale image (values 0-255) with images (imageMatrix...as grey) the image is created with inverse colours. My first question is how can i plot the image with the default grey values. In the application the greys are (ImageJ): white=0,black=255.
I would be also interested in operations on images inside R to test some image functionality. So which packages exist to do some image operations and how can i create and plot images with them (with available data structures like a list or a matrix)? Another point is the creation of coloured images inside R. How could i create and plot coloured images inside R and which data structure do i need? In addition to this question for coloured images -> are there any bit arithmetics available to seperate the colour space or do i have to transfer the rgb values seperately? Any help is appreciated With kind regards Marcel -- View this message in context: http://www.nabble.com/Image-analysis-and-image-questions-tf4611810.html#a13170210 Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
