Alphablending is supported by the FCLImage library coming together with FPC (https://wiki.freepascal.org/fcl-image). Find an Alphablend example in the attachment (it has no GUI and just creates an alpha-blended png image). Note that this library is not compatible with the standard handle-based graphics library. You may want to use TLazIntfImage and TLazCanvas to take advantage of both worlds (https://wiki.freepascal.org/Developing_with_Graphics#Working_with_TLazIntfImage,_TRawImage_and_TLazCanvas).
