How to display bmp or jpg files in an intensity graph?

[ntom]

Hi,

Is there a simple way to convert any bitmap or jpg into a two dimensional array? Can LabView automatically detect all setting form the files?

Thanks in advance.

If you have at least LabVIEW Full Development take a look at the Picture Control Palette (Graphics & Sound->Graphic Formats). There are fucntions to load BMP, PNG and JPG files into a Picture Control. To convert the resulting picture map into a two dimensional array to display in an Intensity Graph isn't that difficult but will require a little work from your side. For more than 256 colors it will also be difficult to do.

The OpenG Toolkit library at www.OpenG.org does have a function which tries to auto-detect the type of image based on the file ending (the not so smart but easy to do way) and load the image accordingly.

Hi,

Do you have any idea how i could preserve the original multicolors of the jpg/BMP instead of getting  the grayscale or false color?

Hi Sacha,

get the colors of your image. Reduce them to 256 colors max, if more colors are used. Set the z axis of the intensity graph (aka colormap)…
