Hello all, I'm getting a 0xC0000005: Access Violation while in a call to the function TIFFReadRGBAImage().
What I am trying to do is discover if a TIFF file is corrupt or not. If I read the file successfully then it's ok, if not it's corrupt. I have the following code:
TIFF* tif = TIFFOpen((LPCSTR)tmpFile, "r");
if (tif) {
uint32 w, h;
size_t npixels;
uint32* raster;
TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &w);
TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &h);
npixels = w * h;
raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32));
if (raster != NULL) {
if (TIFFReadRGBAImage(tif, w, h, raster, 0)) // ERROR OCCURS HERE
result = true;
_TIFFfree(raster);
}
TIFFClose(tif);
}
Im using the following:
Win 2k + SP2
Visual Studio 6 + Service Pack
----------------------------
Also when building the tiff library, I included /MDd in the makefile as I have this switch present in the VC project I'm working with. I got the following warnings while building:
