how do I covert a 2D-array to a grayscale picture without using IMAQ

[soslotos]

I can't find the array to image vi in my labview 7.1(there is only image to array vi)
so I want to covert the array to a grayscale picture without using IMAQ


Another question:my labview 7.1 can only covert the programs to the version of 7.0,but I want to convert it to 6.0.

(1) Try "flatten pixmap" (It is in the graphics&Sound...Graphics Format Palette).

(2) To convert to version 6.0 from 7.1, you need to use 7.1 to convert to 7.0, then open it in LabVIEW 7.0 to save as 6.1, then open it in 6.1 and save as 6.0. You need all version in-between.

Alternatively, you can post the VI here and somebody can probably convert it for you. Remember that a lot of functionality has been added since 6.0, so if you use any of the newer functions (e.g. express VIs), it will not be easy to convert to an older version.

thank you very much
I have tried to use the flattened pixmap but failed
could you please show me an example about how to convert a 2D-array to an gray picture? thank you

The attached VI (LabVIEW 7.1) Shows two possibilities using some generated data.

hi dear alten

i want to create color.
that mean:

in your color(that connect to Flattened pixmap) if my one of number in the 2D array is 0 or lower the color in  output picture
is black and for 256 the color is white.
my problem is that i want to have red for 128 and blue for -128 like the image that i attach.

thank you so much for your help.

Just change the color of the Z scale. You can right-click on any marker and set the color and value.

thank you altenbach

but i can't understand your purpose.
if it's possible for you explain more, and set a vi for me.

thank you so much.
