plotting a bmp file and concatination with polor plot

[tanu]

i have developed one graphical application where i am concatinating a 24 bit bmp file and labview polor plot in a picture box where a line is rotating continiously with 0.5 degree resolution by changing the data in polor vi.Now i have placed one boolean button in the centre of the polor plot.when the program is running the button is also moving along the radius of the circle(following the line)by changing the data in the top and left property of the boolean button.

The problem is that when i am removing the bmp file the bollean button runs very fast but when bmp file is there the program anyway running slow as a result boolean button also running slow.

what is the solution.i want both,the picture(bmp) as well as fast movement of the button.
i am attaching the application program.it is developed in 6.1.

You forgot to attach the program

bmp is raster, display slow in picture control; while polar plot is vector, draws faster.

If the bmp is not changing, you can use it as background behind the picture control.

If the bmp is changing, maybe you can convert it to 8 bit bmp, so it can be redraw faster.

Simply drag & drop it onto your front panel. Make it bottom layer (Ctrl+J).
