Example 10.5 Modifying page contents

//Declare objects used in this code example
PDEElement pdeElement;
ASFixedRect bbox;
AVRect rect;
PDColorValueRec red, blue;
//Define red
red.space = PDDeviceRGB;
red.value[0] = ASInt32ToFixed(1);
red.value[1] = 0;
red.value[2] = 0;
//Define blue
blue.space = PDDeviceRGB;
blue.value[0] = 0;
blue.value[1] = 0;
blue.value[2] = ASInt32ToFixed(1);
//Create a PDEContent object based on the current page view
AVDoc avDoc = AVAppGetActiveDoc();
AVPageView pageView = AVDocGetPageView(avDoc);
PDPageNumber pageNum = AVPageViewGetPageNum(pageView);
PDDoc pdDoc = AVDocGetPDDoc(avDoc);
PDPage pdPage = PDDocAcquirePage(pdDoc, pageNum);
PDEContent pdeContent = PDPageAcquirePDEContent(pdPage, gExtensionID);
//Get the number of elements located in the PDEContent object
ASInt32 eleNum = PDEContentGetNumElems(pdeContent);
//Retrieve each element in the PDEContent object
for (int j=0; j < eleNum; j++){
//Get a specific element
pdeElement = PDEContentGetElem(pdeContent, j);
//Determine if the object is of type text
if (PDEObjectGetType((PDEObject) pdeElement) == kPDEText){
//Get the number of text runs in the text element
int numTextRuns = PDETextGetNumRuns((PDEText) pdeElement);
//Assign red to the page view
AVPageViewSetColor(pageView, &red);
