Hello Charlie, my suggestion is to move the "Image with String"-Patch outside the "Render in Image" and set the "Image Width" and "Image Height" parameters of it to zero (then the resulting string image is exactly the right size). Then you can use the "Image Dimension" patch to get the image pixel size and add a padding to it. The new width and height is then used for the "Render in Image" patch as "Pixels Wide" and "Pixels Heigh" parameter. You may also apply a "max" to the width, so the image is at least e.g. 200 pixels. Then you feed in the string image inside the "Render in Image" patch and render it there just like you did.
A second idea is to use pixel units only in your calculations. I see sometimes a gab between "Monday" and "10:00pm". I think thats because your "Monday"-scaled image pixel dimensions is odd and divided by "2" get a 0.5 friction. And because you are using "Pixel Aligned" drawing in the Billboard the images gets apart by a pixel. best, Achim Breidenbach Boinx Software On 05.05.2011, at 18:25, Charlie Francis wrote: > Right, this next one might be a bit far removed from the first question, but > it kind of follows on with what I'm trying to do. > > > A little oversight: > This will be placed over a video and be sent to the web and TV, so needs to > be able to squash to the 720x576 DV PAL Widescreen Aspect Ratio and also stay > at the 1024x576 Square Pixel Aspect Ratio.
