Adjusting Bitmap color range

krummelt1 — Wed, 31 Mar 2004 17:41:21 GMT

Hello everyone
I am currently using Labview ver 7.0. I currently have a bitmap picture of an AutoCAD drawing that I would like to edit programmatically. Basically I have some temperature sensors on my hardware and I would like to add a color range to a specific spot on my bitmap image. The way it would function is that as the temperature increased at the sensor, the color of that specific area in the bitmap would change color (yellow to red or something)

My thought right now is to possibly try and accomplish this with either custom shaped color boxes, or by creating sections on my drawing and being able to color each section separately (similar to how you can section a picture for website links).

The picture contains sections that a
re not square so a custom shape is best.

If I have been unclear or feel I have left something out please contact me and I will try to be more descriptive. Thanks
TK

The easiest way to do that would be to use a picture ring and modify the bitmap image for all the stages that you would need and place them into the picture ring and update the ring for each case.

does anyone know how I can actually make a "color area" I want to make the colors fade from one to another, the same way a meter does

This is an example of how to draw colors onto an image. it is very crude but you get the picture. HAHA. seriously. I think this will point you in the right direction. you can find everything you need on the grapics and sound pallette.if this does not help repost your question and I won't answer it.
Sorry I could not be of more help.

Take a look at Mask Example.vi. It is a shipping example that shows how to mask of areas of a picture control for coloring.

I am think that you can put your image in a picture control and then overlay an image having custom color regions. You can then adjust the custom colors.
