To attach a pop-up menu:

Add the following code to the ui file to create a pop-up menu:

nuiPushMenu(“Tools”);

nuiPushToolBox(“Transform”);

nuiToolBoxItem(“@VidResize”,VidResize());

nuiPopToolBox();

nuiPopMenu();

nuxDefExprToggle(“VidResize.keepAspect”);

nuiPushControlGroup(“VidResize.Background Color”);

nuiGroupControl(“VidResize.bgRed”);
nuiGroupControl(“VidResize.bgGreen”);
nuiGroupControl(“VidResize.bgBlue”);

nuiPopControlGroup();
nuiPushControlWidget(“VidResize.Background Color”,
nuiConnectColorPControl(kRGBToggle,kCurrentColor,1)
);
nuxDefMultiChoice(“VidResize.vidFormat”, “NTSC|PAL”);

You can add as many entries as you want, and each entry is separated by the “|”
symbol. There is a problem with pop-up menus, however. As mentioned above, pop-up
menus only return the word you entered. Therefore, you must change the startup
macro file. In VidResize.h in the startup directory, change vidFormat to be a string
instead of an integer, placing its default parameter as either NTSC or PAL, both in
quotes. You also use an if/else statement below it to evaluate vidFormat and assign the
proper yRes value based on the vidFormat value.

Edit the VidResize.h file in startup to change the vidFormat logic to deal with strings
instead of integers:

image VidResize(
image In=0,
int keepAspect=1, //keeps aspect ratio or not
string vidFormat=“NTSC”, //This select NTSC or PAL res
float bgRed=0, //if keeping aspect ratio, determines
float bgGreen=0, //the bg color
float bgBlue=0
)
{
if (vidFormat==“NTSC”){

yRes=486;
} else {
yRes=576;
}

// curve int yRes = vidFormat==0?486:576;

Fit1 = Fit(In, 720, yRes, “default”, xFilter, 1);
Resize1 = Resize(In, 720, yRes, “default”, 0);
SetBGColor1 = SetBGColor(Fit1, “rgbaz”,
bgRed, bgGreen, bgBlue, 0,0
