8–11 Error Codes
56 Insufficient memory for another LOGO call
IGP/PGL memory cannot store another logo call. To create space in the
IGP/PGL memory, delete forms with logo elements (including the logos) no
longer required.
57 LOGO call starting row SR out of bounds
During form creation, the parameter specifying the row position of a logo
places the logo above or below the margins of the form. The buffer is flushed
until a line terminator is found, and then processing continues normally.
58 LOGO call starting column SC out of bounds
During form creation, the parameter specifying the column position of a logo
places the logo outside the form boundaries. When this occurs, the buffer is
flushed until a line terminator is found, and then processing continues
normally.
59 Color or GRAY scale not supported with LOGOS
Color or gray scale information was received from the TIFF data, but it is not
supported with the LOGO command.
