I was written program which slowly change Pic1 to Pic2. It's only work with Bmp pictures, because i use Bitmap.ScanLine procedure for fast work with pixels<br />
(ScanLine - Provides indexed access to each line of pixels)<br />
<br />
If I load Jpg picture in TImage picture property cange to TJPEGImage,<br />
but Image1.Picture.Bitmap is empty.<br />
<br />
if i use Pixels[x,y] for get color it's to slow<br />
(for pictures 1000x800 &nbsp;cca 800 times)<br />
<br />
<br />
My questions<br />
<br />
How to use TBitMap with jpg picture?<br />
or<br />
Procedure like &quot;ScanLine&quot; for Jpg Pictures ?<br />
or<br />
any suggestions<br />
