Hi BHARATHIN…,

there are other functions in LabView to load and draw a picture. Where do you want to show it??

thanks mike for the prompt reply..I basically want to obtain coordinates of the points on the image i click.i used ginput in matlab to do the same after doin imshow..but im puzzled how to do it in labview..is it possible to do it without mathscript?

Hi BHARATHIN…,

here is in example how you can draw your image if you read it with "imread". But you can also use the "normal" functions to load the picture.

Hi BHARATHIN…,

wherefrom you get your data? For me it sounds like you could use a waveform graph with a cursor.

thanks once again for the help..im actually gettin a JPEG FILE stored in my directory after takin a picture usin my digi camera. i need to find the coordinates of some points in the file.is there some marker option?

Hi BHARATHIN…,

to fing some points in an image, i think you have to analyse it. You can draw lines into your picture, or you read the mouse position.

let me explain in detail..

My application is actually determining the strain in some flexible materials.for that im usin a light marker whose movement is monitored as the body moves.Thus i capture a photograph of initial position ,click on the image of the marker and use the coordinates of the point to draw a frame of reference (a square) around the marker image.as the  body moves the frame has to move.

I thus need coordinates of the point when i click on the marker image of the jpeg file to form the square frame of reference.i have the matlab code to do it but i need to do it in labview

oh thanks.can u pls tell me  how to read mouse position?
