hi Leonard:
I do it like you said, but
Why my image can not display in the pdf.
code is:
//====================================================================
const ASInt32 theImageByteSize = IMG_WIDTH * IMG_HEIGHT;
char* buff = new char[theImageByteSize];
PDEImage volatile pdeImage = NULL;
PDEImageAttrs pdeImageAttrs;
PDEColorSpace pdeColorSpace;
ASFixedMatrix imageMatrix;
memset(&pdeImageAttrs, 0, sizeof(PDEImageAttrs));
int hdl = _open(ImagePath, _O_RDONLY | _O_BINARY, _S_IWRITE | _S_IREAD);
if (hdl == -1)
     AVAlertNote("[%s] create fail !!!!") ;
if (_read(hdl, buff, theImageByteSize) == -1)
     AVAlertNote("read image fail!") ;
pdeImageAttrs.width = IMG_WIDTH;
pdeImageAttrs.height = IMG_HEIGHT;
pdeImageAttrs.intent = ASAtomNull;
pdeImageAttrs.bitsPerComponent = 8;
pdeImageAttrs.flags = kPDEImageExternal | kPDEImageIsIndexed;
pdeImageAttrs.decode[0] = fixedZero;
pdeImageAttrs.decode[1] = fixedOne;
pdeImageAttrs.decode[2] = fixedZero;
pdeImageAttrs.decode[3] = fixedOne;
pdeImageAttrs.decode[4] = fixedZero;
pdeImageAttrs.decode[5] = fixedOne;
ASFixedRect theMediaBox;
PDPageGetMediaBox( AVPageViewGetPage(pageView), &theMediaBox );
ASFixed theFixedWidth = (theMediaBox.right - theMediaBox.left);
ASFixed theFixedHeight = (theMediaBox.top - theMediaBox.bottom);
imageMatrix.a = ASInt16ToFixed(theFixedWidth);
imageMatrix.d = ASInt16ToFixed(theFixedHeight);
imageMatrix.b = imageMatrix.c = fixedZero;
imageMatrix.h = 0;
imageMatrix.v = 0;
const Int32 cPaletteColors = 256;
PDEIndexedColorData theIndexedData;
theIndexedData.size = sizeof(theIndexedData);
theIndexedData.baseCs = PDEColorSpaceCreateFromName(ASAtomFromString( "DeviceRGB"));
theIndexedData.hival = cPaletteColors - 1;
unsigned char data[3] = {255, 0, 0};
theIndexedData.lookup = (char *)data;
theIndexedData.lookupLen = cPaletteColors * 3;
PDEColorSpaceStruct theColorData;
theColorData.indexed = &theIndexedData;
pdeColorSpace = PDEColorSpaceCreate(ASAtomFromString( "Indexed" ), &theColorData );
pdeImage = PDEImageCreate(&pdeImageAttrs, sizeof(pdeImageAttrs), &imageMatrix,
                                            0, pdeColorSpace, NULL, NULL, NULL, (unsigned char*)buff, theImageByteSize);
I want die, I had done this for so many days, My GIF doesn't insert into pdf,
unsigned char data[3] = {255, 0, 0};
theIndexedData.lookup = (char *)data;  "
whether the data set wrong?
I confused what I do next
