Our engineers added L_HighPassFilterBitmap function to LEADTOOLS v14.5 and later versions of LEADTOOLS SDK. This function was not available in LEADTOOLS v13.

Other functions were also added after v13, such as L_AllocFTArray and L_FrqFilterBitmap (v14), which allow you to perform frequency filtering of the image.

If you like to try these functions, you can download the free evaluation edition of LEADTOOLS v16.5 from our site.

Good Morning

I used search on your documentation to find the function L_HighPassFilter with no result.

Rainer,
If you open our LEADTOOLS Raster Imaging C DLL help file, copy and paste the following string in the search tab text box or in the Index tab:
L_HighPassFilterBitmap
A shortcut to the help file can be found here:
[LEADTOOLS 16.5] folder\Shortcuts\C DLL\01 Raster Imaging Help.lnk

Also, this is a link to our online documentation for this topic:
