Hi , brothers!!!
Today , I got a very headache problem of display an image by using the class of "GdalRasterLayer";
The problem is :
if my image data value is between 0- 255 .all right, There is no problem. This image can show very well !!!
however , If my image data value is between 0 -1. The problem comes up! this image shown as all pixels black color!
so , this is not what i want to see.
When I use IDL to display the image with data value between 0 and 1, I can use the function of " TVSCL " to sovle this problem!
The point is , How can I change the range of my Image data value of 0-1 to 0-255 to dislay the image exactly!
looking forword to your replay!
