Possible Issues
Enum DisplayableTypes
Raw, Baseline, BaselineCorrected, Denoised, Centroids, Peaks
Public Members
Name - spectra name
Classification[] - collection of classifications(string descriptors) for this spectra
Color - color to represent this spectra
RawCurve[] - collection of points creating raw signal
BaselineCurve[] - collection of points creating baseline curve
BaselineCorrectedCurve[] - collection of points representing the raw signal after baseline correction
Possibly can be derived instead of stored separate?
DenoisedCurve[] - collection of points showing denoised data
Possibly can just be a collection of indices of 'valid' points from RawCurve?
Centroids[] - collection of ranges (start and end point) of centroids
Possibly can be derived from DenoisedCurve?
Peaks[] - collection of points showing peaks
The same as the DenoisedCurve, drawn differently?
Possible Issues
Memory size limitation for numerous spectra
Possibly use memory-mapped version?
Hold file index of most-recently acessed leftmost point (left limit of window) and continue to read from there onwards
Keep a cache of 50 or so points ('valid points' as defined in
SpectraDisplay
) in memory for redrawing
Possibly draw once as static bitmap, then only redraw on zoom?
Would have to calculate visibility of points, and only draw over parts of current image if the visibility would change or be effected.
Somewhat complex system of layering to determine what must be redrawn, but system could be reused
Occlusion detection algorithms for adding information - removing information same, just set color to white
Policy of always adding most recent information to top?
