Options set with environment variables are overridden if the same option is also specified on the command line. Options set with DXARGS are overridden by both environment variables and explicit command line options. DDDDXXXX8888BBBBIIIITTTTCCCCMMMMAAAAPPPP When Data Explorer displays images in 8-bit windows, it makes every effort to create an accurate representation of the image using the default colormap shared among applications using 8-bit windows. If the colors required by Data Explorer are not present in the colormap and there are not enough free color cells available in the shared color map for their allocation, Data Explorer will find approximations among the colors that are available. However, in certain circumstances, the difference between the desired color and the approximation is found to be too great to be acceptable. In such circumstances, DX will allocate a private colormap for more accurate results. In this case, depending on your X server, you may need to move the mouse to select the Image or Display window in order for the correct colors to appear. The -8bitcmap Page 8 (printed 12/22/98) DDDDXXXX((((1111VVVV)))) IIIIBBBBMMMM VVVViiiissssuuuuaaaalllliiiizzzzaaaattttiiiioooonnnn DDDDaaaattttaaaa EEEExxxxpppplllloooorrrreeeerrrr DDDDXXXX((((1111VVVV)))) flag sets the level at which the change to using a private colormap is made. The value of this parameter should be a number between 0 and 1, or "private" or "shared", and it repressents the Euclidean distance in RGB color space, normalized to 1, for the maximum allowed discrepancy. If you set this parameter to 1, then a private colormap will never be used. If you set it to -1, then a private colormap will always be used. The default is 0.1. DDDDXXXXAAAARRRRGGGGSSSS This contains the default set of arguments used by the _d_x script. The arguments are prepended to those given to _d_x on the command line.
