Graphics FormatThis format allows the user to input data in PNG, GIF, or JPG format.Graphics files are really intended only as a way of reading in non-xray data, for example produced as a Fourier transform of some optical image. A graphics file is not the same as the original data file. A typical data file is 1024x1024 pixels, and has a depth of at least 16 bits (depending on the detector type). Graphics images are generally much smaller (so spatial resolution has been lost) and have much less dynamic range. Additionally, note that Datasqueeze expects grayscale images. It converts the image color to an intensity by adding the red, blue, and green components. The GIF format is copyrighted by Unisys Corporation. |
