Hi.

I'm looking for the easiest way to "shrink" a scanned picture.
I need a 10% smaller duplicate of my previous scanned picture,
but it's got to have the same size. I need a border arround my picture,
that's why I have to shrink it.

Hello,

What is the exact LEADTOOLS version that you use?
And what is the programming interface that you use?

Thanks,

Hello,

You can use the Size method (Main Control) to resize the bitmap to a new width and height.
For more information, please refer to the LEADTOOLS documentation and read the related topic.

Thanks,

Hello,

Actually, the Size method is one step. The full steps are:
1. Use a second control and create a blank image with the same size and pixel depth as the original using CreateBitmap method.
2. Fill the new image with the border color you want using the Fill method
3. Resize (shrink) the original image using the Size method
4. Copy the pixel data from the 'shrunk' image to the new image using the Combine method.

Thanks,

Make sure you are completing Maen's step 3 properly before combining as in Step 4.  The image you combined onto the black background is the same size and it looks like you only cropped the image rather than shrinking it with using the Size method.

I think i did it right, but thats's my code
         AxLEAD1.Load("c:\test.tif", 1, 1, 1)
        AxLEAD2.CreateBitmap(AxLEAD1.InfoWidth, AxLEAD1.InfoHeight, 1)
        Dim leadsize As System.Drawing.Size
        leadsize = New System.Drawing.Size(AxLEAD1.InfoWidth * 0.94, AxLEAD1.InfoHeight * 0.94)
        AxLEAD1.Size = leadsize
        AxLEAD2.BitmapHeight = AxLEAD1.InfoHeight * 0.94
        AxLEAD2.Size = leadsize
        AxLEAD2.Fill(System.UInt32.Parse("FFFFFF", Globalization.NumberStyles.HexNumber))
        AxLEAD2.Combine(AxLEAD2.Width * 0.03, AxLEAD2.Height * 0.03, AxLEAD2.Width * 0.94, AxLEAD2.Height * 0.94,         AxLEAD1.Bitmap, 0, 0, 801)
        AxLEAD2.ForceRepaint()
        AxLEAD2.AutoRepaint = True
        AxLEAD1.Visible = False
        AxLEAD2.Top = 0
        AxLEAD2.Left = 0
        AxLEAD2.Width = 200
        AxLEAD2.Height = 200
        AxLEAD2.Flip()
        AxLEAD2.Save("c:\test2.tif", 29, 1, 0, 0)
Could you please check, if there's a mistake in my code?

Thanks Stefan

Hello,

Please try to use the following code:
+-----------------------------------+
AxLEAD1.PaintSizeMode = LEADLib.PaintSizeModeConstants.PAINTSIZEMODE_FIT
AxLEAD2.PaintSizeMode = LEADLib.PaintSizeModeConstants.PAINTSIZEMODE_FIT
AxLEAD1.Load("c:\fax1.tif", 1, 1, 1)
AxLEAD2.CreateBitmap(AxLEAD1.InfoWidth, AxLEAD1.InfoHeight, 1)
AxLEAD1.CtlSize(AxLEAD1.BitmapWidth * 0.94, AxLEAD1.BitmapHeight * 0.94, 0)
AxLEAD2.Fill(System.UInt32.Parse("FFFFFF", Globalization.NumberStyles.HexNumber))
AxLEAD1.Combine((AxLEAD2.BitmapWidth - AxLEAD1.BitmapWidth) / 2, (AxLEAD2.BitmapHeight - AxLEAD1.BitmapHeight) / 2, AxLEAD1.BitmapWidth, AxLEAD1.BitmapHeight, AxLEAD1.Bitmap, 0, 0, LEADLib.CombineConstants.CB_OP_ADD And LEADLib.CombineConstants.CB_DST_0)
AxLEAD2.ForceRepaint()
AxLEAD2.AutoRepaint = True
AxLEAD1.Visible = True
+-----------------------------------+

Hi,

i've found a mistake in your code
It must be AxLead2.combine(.......),
but after changing this, it worked great.

Thanks a lot!

Stefan
