The following application procedures exist : ! ! addpars add parameters to each record of ASCII file ! ! asload assign display window + load an image into it ! ! areatable build a table with areas of equal size covering an image ! ! autocuts determine `good' cuts for loading of an image ! ! buildcube build a cube from a set of 2-dim frames ! ! catalsync synchronize catalog entries ! ! checker create a checkerboard pattern ! ! checkname check name of Midas file for illegal characters ! ! compFITS compare primary headers of FITS files ! ! compdelta compute difference image ! ! convolfft convolve/correlate two images via FFT ! ! copyfile copy an ASCII files omitting specific records (lines) ! ! diffdsc compare the descriptors (FITS header) of two Midas images ! ! diffima compare the pixels of two Midas images ! ! diffimage compare images in different directories ! ! difftable compare tables in different directories ! ! dscedit edit a descriptor ! ! edges find edges using Sobel or Prewitt filter ! ! expand expand an image by folding over of rows and columns at the ! borders ! ! fonttxt show text in any chosen font and browse font data base ! ! fastcomp compute fast ln, log10 or sqrt functions ! ! func2d create image according to any 2-dim function ! ! fftfilt filter an image in the Fourier domain ! ! gammacorr create ITT to apply gamma correction for "good" hardcopy ! ! getcoord translate frame pixels to world coords and vice versa ! ! histogram image to image histogram transformation ! ! matconst define some often used mathematical constants ! ! normalize map pixel values into [0.,1.] ! ! outima convert Midas images to other formats (e.g. GIF) ! ! packdsc pack descriptors of a Midas file (reclaim space from ! previously deleted descriptors) ! ! perspec build + display 3-dim perspective view of cube ! ! polyrep mark polygon in overlay channel and replace image ! according to edges of that polygon ! ! plottab plot contents of a colour LookUpTable or ITT ! ! prhelp print this help ! ! replace use more elaborate expressions for replacing pixels than ! is possible in REPLACE/IMAGE ! ! resetback reset the connection with a background Midas ! ! sancheck check the sanity of an image frame, i.e. test if there are ! any NaN or Inf in the data ! ! scale scale image data into given range ! ! scaler scale images (pixels) the same way as in ! LOAD/IMAGE but on disk ! ! scanima reconstruct a 1-dim image from a 2-dim frame representing ! the plot of that image ! ! send_mess display message(s) (centered) on display ! ! sharpen sharpen an image via Gaussian unsharp masking ! ! showfonts show the fonts which can be used in Midas (LABEL/DISPLAY) ! ! showmidas display current setup of MIDAS ! ! slicube extract a 2-D slice from a 3-D cube ! ! swap4 swap the 4 quadrants of an image diagonally ! ! vertlut integrate vertical LUT with tick marks into display ! ! zperspec build + display 3-dim perspective view of 2-dim frame ! !
