setting picture size

[aka]

hi there,

trying to set the size of a picture, i read its "rect" data and then pass this to:

draw flattened pixmap.vi or draw rect.vi

i get no errors, neither control over the size...

the question really is:

a) how to create a new (empty) pic of a specified size

b) how to control the borders when opening an existing pic so that they fit perfectly around it

c) is it possible to display a pic without borders?

working on LabView 6.0 ad 7.0

thanks a lot,

alex

It sounds like you are getting the image data mixed up with the Picture control that will contain the image. All that Draw Flattened Pixmap does is take a cluster of image data and turns that into a LabVIEW picture data type. You then need to wire the picture output of that VI to a Picture control. You can set the size of the Picture control with a property node using the Draw Area Size property. I don't think you can actually turn off the border, but you might be able to customize the Picture control and set its border color to transparent.

eaolson, you're right-thanks for the pointer!

Ans: the way is to customize the Picture control and move its border color to the background (the actual figure in on a 'higher' layer, thus covering the border). this works even when the picture control is programmatically resized.
