Hi,

i have always used TIEBitmap.TBitmapScanlines


Exemple:
Row: PRGBTripleArray;

if aIEBitmap.PixelFormat <> ie24RGB then
aIEBitmap.PixelFormat := ie24RGB;

Row := aIEBitmap.TBitmapScanlines[y];

But, today i have an error reading valid row.
So, i have tryied :
Row := aIEBitmap.Scanline[y];

and it works,
What is the differnce between them and can i replace TBitmapScanlines ?

Thanks,
Mauricio

Hi Mauricio

Sorry, I will improve the documentation for that.

TBitmapScanlines is only valid if TIEBitmap.Location=ieTBitmap, in other cases it is invalid. You are better to use TIEBitmap.Scanline, which supports all locations.

When TIEBitmap.Location=ieTBitmap then TIEBitmap.Scanline returns TBitmapScanlines anyway.
