Image processing libraries and VHDL

Hello,

I am starting to work on Spartran FPGA. and most of my work will be related to image processing. I never worked with xilinx chips and webpack before. So, would any one advice me that does xilinx offers any image processing libraries ( for VHDL ) like for example MATLab does and any sample code or example to use those libraries in VHDL coding.

Please advice!

Thanks Regards John
