Origin 7.5 SR6
Windows XP SP2

I am looking for a function that will convert mm to pixels. Is there a Origin C or Labtalk function that will perform this operation?

Thanks,

There is no build-in function for this. However, you can get the page resolution (in PPI) with LabTalk scripts page.resX (Horizontal resolution) and page.resY (vertical resolution). Then you can convert it from mm to pixels with the calcualtion of mm -> inchs -> pixels.

Here's another LabTalk script that can be run when any worksheet, graph or matrix window is active.

lusave=layer.unit;
layer.unit=4; // unit = mm
width_in_mm=layer.width;
width_in_mm=;
layer.unit=5; // unit = pixel
width_in_pixel=layer.width;
width_in_pixel=;
layer.unit=lusave;
pixels_per_mm=width_in_pixel/width_in_mm;
pixels_per_mm=;
