I will use an app to create an animated gif is much easier at the end.
I have a problem with the cgSnapshot. I wanted to create different folders each time for different level and iteration. At first I saved everything in one folder but it was too messy (Vectors(i,level,iter)).
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
void = cgSnapshot(/tif, Filename = 'C:\Users\Desktop\FOLDER\Vectors('+string(i)+','+string(leve l)+','+strtrim(iter)+')', /NoDialog)
endfor
I wanted to save all the time points (i) for each level and iter respectively in a separate folder.
void = cgSnapshot(/JPEG, Filename='C:\Users\Desktop\FOLDER\Vector_Folder('+string(lev el)+','+strtrim(iter)+')\Vectors('+string(i)+')', /NoDialog)
I got this error:"Error opening file".
Is that necessary to create the folders in advanced? They cannot be create during the process?
Because before I did something like that but not with the cgsnapshot
