Hello all,
Example of the problem:
I need to resize a ROI (oversample) obtained from image1 (100x100)
and show it in image2 (200x200).
I had success in creating a tool to downsample the ROI (the inverse
problem), but do oversample, the ROI is not exactly what I want, have
somr borders problem.
Well, seeing the file "envi_all_functions.txt" that I dont know from
where it cames, theres is method with a sintaxe:
DISP_ROI_GROW_REGION, p_data, /ASK, /GROUP, /REDO
I ask if someone had used this routine, and dont know how to initiate
p_data.
Maybe I can help showing my code here (to oversample):
; ***************************
; Growing for x axis
; ***************************
; x is a long array with the xaxis positions
xSize = n_elements(x)
xNewSize = xSize * intScaleFactor * intScaleFactor
xNew = lonarr(xNewSize)
xNew[*] = -1
currentXnewIndex = 0
for xi=0, xSize-1 do begin
numberToWrite = x[xi]
; The box side for every x
for sfRepeater = 0, intScaleFactor-1 do begin
; The box side for current element of x (xi)
for sfRepeaterNested = 0, intScaleFactor-1 do begin
; Verifying the image limit
if numberToWrite lt lngDestinationWidth then begin
xNew[currentXnewIndex++] =
numberToWrite
endif
endfor
numberToWrite++
endfor
endfor
; Removing invalid indexes
goodIndex = where(xNew ne -1)
if goodIndex[0] ne -1 then xNew = xNew[goodIndex]
x = tem****ary(xNew)
