Hi,

Please find the below codes,

BT
0 Tw
/F0 1 Tf 100 Tz
 0 g
1 0 0 1 0 0 Tm 263.52 793.66 Td(70403179)Tj

How to use this Tz operator here. I found in PdfReference that "Set the horizontal scaling, Th, to (scale ÷ 100). scale shall be a number specifying the percentage of the normal width. Initial value: 100 (normal width)."

How to do this with Tm .. According to this Tm i am making only translate transform since 1 'a' and 'd' values of matrix are available.. how to perform scaling here??

As specified in Pdf reference am not having Th(above code)..??

Thanks in Advance,
Mei

You should be following the formulae in 9.4.4 "Text space details", where Th is used to update Tm and generate Trm. For the text space parameters like this, ignore the commentary if it is confusing, since it does not change what you need to do. It is all in the forumulae.
