Read text image data -Error

[symlet]

Hi,

I try simulate testbench code for read text image data. I have includes all the package required (textio), but I get this error:

"Error (10482): VHDL error at INPIMAGE.VHD(150): object "HREAD" is used but not declared"

Below is the pieces of the code. Anyone know/familiar with this, please advise.Thank You
