Hi all,
Check out this code segment. While compiling i get an error
that "error: too many arguments to function `GcGetCurrentContext'".ie;
at GcGetCurrentContext(gc) method call. How can i pass the GcHandle to
GcGetCurrentContext().
What could be the issue behind this.. Please help.
bmpP = BmpCreate(10, 10, 8, NULL, &error);
if (bmpP) {
gc = GcCreateBitmapContext(bmpP);
if (gc) {
GcSetColor(gc, 0, 0, 0, 255);
GcRoundRect(gc, 0, 0, 50, 15, 3, 3);
GcPaint(gc);
/* etc */
GcReleaseContext(gc);
}
}
gcBitmap = FrmGetBitmapHandle(formP, gAppDB, bitmapRsc,
1100, 0);
//if (!gcBitmap)
//return memErrNotEnoughSpace;
GcGetCurrentContext(gc);
if (gc) {
GcDrawBitmapAt(gc, gcBitmap, NULL, 30, 50);
GcReleaseContext(gc);
}

After that we tried displaying image using the following code. The
image displayed in device is distorted and not clear .Please go through
this code segment and guide us.
void createbitmap()

pData = bmpRead(); // reads bitmap data
bmpV3P = BmpCreateBitmapV3(bmpP,kDensityDouble,pData,NULL);
WinDrawBitmap((BitmapType*)bmpV3P,50,50);
}
char* bmpRead()

err = VFSFileOpen (volRefNum, path, vfsModeRead,
&fref);
bufH = MemHandleNew (9716);
bufBaseP = MemHandleLock (bufH);
err = VFSFileRead (fref, 9716, bufBaseP, &rb);
VFSFileClose (fref);
MemHandleUnlock (bufH);
MemHandleFree (bufH);
return(bufBaseP);
}
