Hi,

what is the best way to create a thumbnail using v15?

I already read about using some averaging before using L_sizebitmap or there is also the Lsizebitmapinterpolate. But which interpolation algo would be best suited then..?

thanks
matthias

Matthias,




If the image is already loaded into LEADTOOLS, you can use
either L_SizeBitmap or L_SizeBitmapInterpolate to resize it. The difference is
that L_SizeBitmapInterpolate offers more algorithms to choose from, and the
best one depends on your images and the results you want. This means you have to compare them for yourself to decide.


If the image is not yet loaded and is still in a disk file,
you don't need to load the full size image to create a thumbnail. In that case,
you can use the L_CreateThumbnailFromFile function, or the L_LoadBitmapResize function. This will save time and memory.
