Hi all, I am using savePlot in a loop for saving several graph but I get some graph in 553x552, some other in 1920x1119. How comes ? My data are almost all the same (same label, same xlim / ylim, almost same data. Only the color changes). I save them in bmp. Thanks for your help. Christophe

Rather than using a Windows Device and copying the contents, just use the bmp() device directly if you really want bitmaps. Uwe Ligges

I do not want a bitmaps. I use savePlot in a library, so I let the user decide whith export he wants. Christophe

Then, why not let the user choose a proper device? Anyway, the resulting bitmap is copied from the screen device, that means the size is also copied. That means if you have some 1600x1200 screen and your windows device is resized to fullscreen, than you will almost get 1600x1200 pixels in your bitmap... Uwe Ligges

Because I program a graphical interface that let the user to chose the graph he want to export (that can be one but also 50). Then he sets dynamicaly the parameters for all the graphics he wants to export. Then all the graphs are exported at once.
Anyway, the resulting bitmap is copied from the screen device, that means the size is also copied. That means if you have some 1600x1200 screen and your windows device is resized to fullscreen, than you will almost get 1600x1200 pixels in your bitmap...
Ok, the "strange behevior" was occuring because I change the size of the windows during the export... Thanks a lot Christophe
