Topic: ASFixed Problem
Conf: (P-PDF) Developers, Msg: 51775

Dear all, I'm getting an ASFixedRect structure from PDETextGetBBox, and
trying to subtract a number from each of the memebers of the ASFixedRect
(.left, .top etc) however in debug mode I noticed for example in the
following sample code:

ASFixedRect fontBBox;
PDETextGetBBox(theTextElem, kPDETextRun, 0, &fontBBox);
char* fontBox= new char[255];
ASFixedToCString(fontBBox.top, fontBox, 255, 0);

that fontBBox.top actually gives me something like 4334889 while if I
convert it to a CString fontBox and write to a text file it would turn out
to be 760... and if I tried something like this:

ASFixed temp = fontBBox.top;
ASFixedTruncToInt32(temp); // or ASFixedRoundToInt32 same happens
temp=768-temp;
ASInt32ToFixed(temp);

before changing it to a CString, the number in temp (debug mode) still reads
something like 4397839 very strange... and turning it into a CString would
give -760... which basically is a -ve of the original fontBBox.top... why is
it doing that? I tried just (768-fontBBox.top) and still does the exact
thing...

Please help this newbie...

Thanx, Julius
