[Scilab-users] Exporting graphics as non pink jpg with xinit/xend

[Rafael Guerra]

Jens,

Check the following with an extra loop, it works fine for me:

///// START OF CODE
driver("JPG");
xdel()
y=[];
for i=1:3
    str = "test" + string(i) + ".jpg";
    xinit(str);
    x=[0 1];
    y(i,:)= j*x;
    for j=1:i
        plot(x,y(j,:));
    end
    xend();
end
///// END OF CODE

Regards,
Rafael

Thanks Rafael,

The three files are not pink (which is great) but do not show what I want. I want to have superposed plots, i.e.
test1.jpg should show one line (namely (x,1*x), that's the case)
test2.jpg should show two lines (namely (x,2*x) and (x,1*x), that's not the case)
test3.jpg should show three lines (namely (x,3*x) and (x,2*x) and (x,1*x,that's not the case)

Consecutive plots are normally superposed in Scilab. But here we get just the new ones.

Do you see a way to unpink superposed plots? I am trying for hours with no succes.

Kind regards
Jens

Hi Jens,

Just to let you know that in my Win7 Scilab 5.5.2 installation, the code here below outputs 3 proper JPEGs with no pink colors:

////// START OF CODE
driver("JPG");
xdel()
for i=1:3
    str = "test" + string(i) + ".jpg";
    xinit(str);
    x=[0 1];
    plot(x,i*x)
    f = gcf();
    xend();
    winopen(str);
    halt()
end
////// END OF CODE

PS: all 3 files look good in IrfanView 64-bits.

Regards,
Rafael

Correction: The first phrase should read: In the following script I would like to save the sequential plots as (pinkless) JPGs.

Hi,
In the following script I would like to save the sequential plot result as a pinkless jpg. I found no way to adapt the xinit/xend workaround (for xs2jpg) to this case. After execution I would like to have three JPGs containing one, two and three lines .

xdel()

for i=1:3

    x=[0 1];

    plot(x,i*x)

    halt()

end
In my real project the plots are param3d and plot3d. I hope that makes no difference.

Hoping for help with kind regards
Jens
