Subject: Tiff Resizing and resolution

I have solved my own question on this. As I have noticed others having this problem I've included code that works.

bool Main::ImageConvert(String FilePathName)
{
TResizeTransform *Transform;
bool retval = false;
TTiffGraphic *tif;
int i;

if ((tif = new (TTiffGraphic)) != NULL) {
if ((Transform = new (TResizeTransform)) != NULL)
retval = true;
}

if (retval) {
retval = false;

try {
tif->LoadFromFile(FilePathName);
retval = true;
}
catch(Exception &exc) {
;
}
}

if (retval) {
retval = false;
try {
Transform->Width = (int)((double)tif->Width * 1.5);
Transform->Height = (int)((double)tif->Height * 1.5);
Transform->Interpolated = false;
Transform->OverrideDestFormat = false;
Transform->Apply(tif);
retval = true;
}
catch(Exception &exc) {
;
}
}

if (retval) {
tif->XDotsPerInch = 300;
tif->YDotsPerInch = 300;

try {
tif->SaveToFile(FilePathName);
retval = true;
}
catch(Exception &exc) {
;
}
}

if (Transform)
delete Transform;

return retval;
}
