The PCSpectraLite software was written for analysing images from the Elliott Instruments TVSPEC spectrometer. However, it can be used for analysing any image of size up to 2048 pixels wide by 2048 pixels high in 24 bit colour bitmap bmp file format and can:
show the X and Y co-ordinates of a pixel in the displayed image and its intensity I;
define a rectangular area of the displayed image for one-dimensional X or Y projection and calculation of area properties;
save the displayed image;
print the displayed image;
change the size of the displayed image;
change the appearance of the displayed image by:
converting from a colour to a greyscale display;
inverting the display;
only displaying pixels above a threshold value;
carry out an analysis of the displayed image by:
producing a plot of the average of every column or row in a selected rectangular area - one dimensional projection;
performing a pixel to wavelength calibration if the zero point and scale factor constants are available in a text file named SpecCal.txt;
saving the projection as a bmp file;
saving the projection as a csv file;
printing the projection;
determining the centroid and counting the pixels above the threshold value in a defined rectangular area;
giving information about the program.
Note that any image that can be opened by Paint can be saved in 24 bit colour bitmap bmp file format and then be analysed using PCSpectraLite.
