Using the Frame Marker PNG's in the SDK

February 20, 2011 - 6:16pm #1

What is the intended application for the small Frame Marker PNG's provided w/ the SDK? (see attached)

Are these simply for reference, or to be used as assets?

If they're assets, how do you work with them? I haven't had much luck w/ the graphics programs I've tried. I can scale them cleanly, but can't break them down.

What I'd like to do, is to remove the gray interiors, or make them transparent, to overlay the frames onto images.

Then you may want to check the Adobe Photoshop manual to do that; here is what I found for instance in the online Help section of Photoshop:

Hi, how to save in 24 bit depends on which Image editor you are using. You should check in the manual of your image editor...

What I do to modify the size of the frames is:

  1. Open whit Photoshop
  2. Go to the upper menu, select Image -> Mode -> RGB Color
  3. Then Press cmd+K To open Preferences , then go to General. In the Image Interpolation, you must select Nearest Neighbor (preserve hard edges)
  4. Now you can resize the canvas, add layers, and resize the frame cmd+T to the size you want
  5. You are ready

Pls do. There are a bunch or image manipulation libraries available that could be used to generate these, but it would be nice to work w/ a standardized solution.

Sorry, I've asked but haven't heard back yet. If so, it's probably not a program we can share, but I'll let you know!

Got it, thanks.

Any tips on generating these for ourselves? Were they created programmatically?

They are already rasterized, the only trick is to scale them up without smoothing, use a magic wand on the background and delete the grey. You will have to add a transparency channel though, which might mean changing the color format of the image (to support RGBA).

Thanks I'll try that.

Does the wand work on these as-is, or do they need to be rasterized, or somehow transformed first?

Also how did you guys generate these frame markers? Is there any code that's available for creating them?

If you have access to Photoshop, the magic wand tool can be used to remove the gray interior. GIMP has a similar tool that can be used to select the interior and then clear it. In both cases you will probably need to add a transparency channel if you want to save the image as a png with transparency.
