Script Controls SetPixelScale(1,1): SetDefaultWidth(720); SetDefaultHeight(480); SetDefaultAspect(1); SetDefaultBytes(1); SetDefaultViewerAspect(1); SetFormat("Custom") Command-Line Equivalent -pixelscale 1 1 Description Pixel scale and ratio for the script. See Chapter 4, "Using Proxies," on page 137. If a node goes to black or if you create an image node such as RGrad, it takes this resolution by default. Sets your defaults automatically for resolution and aspect from the precreated list of formats. These formats are stored in your startup .h file in the following format: DefFormatType("Name", width, height, aspectRation, framesPerSecond, fieldRendering); Variables Common Variables width height bytes in, outPoint time width/2 height/2 dod[0], dod[1], dod[2], dod[3] parameterName NodeName.parameterName Description Returns the width of the current node. Returns the height of the current node. Returns the bit depth in bytes, either 1, 2, or 4. Returns the in and out frames of the clip in time. The current frame number. The center of the image in X. The center of the image in Y. The left, bottom, right, and top edges of the Domain of Definition (DOD) of the current image. The value of a parameter within the same node. The value of a parameter in a separate node named NodeName. Macro Examples The following are several examples of macros. Many of these macros can be found in Chapter 32, "The Cookbook," on page 963, but they are not installed by default. Parameter Testing: AutoFit This macro resizes an image to fit a specified size along one dimension. For example, suppose the images in a document are 300, 250, or 166 pixels wide. No matter what size the screen snapshot, you can quickly resize it to one of the standard sizes and easily keep the aspect ratio. Chapter 30 Installing and Creating Macros 929
