I used
help, file
to check whether is a string or a scalar and I got the following
FILE UNDEFINED = <Undefined>
OPENW: Filename argument must be a scalar string: FILE.
I will share my code because maybe I did a mistake somewhere else and I am not able to find it. I have the following procedure. (Image,VX,VY are 3D arrays.)
PRO vectors_overlaid, Image, VX, VY, name
dims_i_need = Size(Dindgen(20,20), /Dimensions)
pos_x = Rebin(Findgen(dims_i_need[0]), dims_i_need[0], dims_i_need[1])
pos_y = Rebin(Reform(Findgen(dims_i_need[1]), 1, dims_i_need[1]), dims_i_need[0], dims_i_need[1])
for i=0L, n-1 do begin
cgDisplay, 500, 550
Image = BYTSCL(Image, min=0.,max=160.)
cgimage,Reform(Image[i,*,*])
cgDrawVectors, REFORM(VX[i,*,*]), REFORM(VY[i,*,*]), pos_x, pos_y,VECCOLORS='yellow', /ORDERED, overplot = 1
write_gif,file, Reform(Image[i,*,*]), /multiple
endfor
write_gif, file, /close
END
Then I called the vectors_overlaid in my main program like this
vectors_overlaid, Image, VX,VY, 'C:\Users\Desktop\Vectors('+string(i,format='(i3.3)')+','+st ring(level)+','+strtrim(iter)+')'.gif'
Why the file is undefined?
