DPI Kya Hai aur Yeh Kyun Zaroori Hai?
DPI ka full form Dots Per Inch hota hai. Yeh darasal ek printing aur scanning measurement hai jo batata hai ki ek inch (1 inch) ke andar kitne dots ya pixels hain. Ek image ka DPI jitna zyada hoga, print ya portal par display hone par uski quality utni hi clear aur sharp aayegi.
“Jaise sarkaar ne khud notification me saaf kaha hai, application forms me clear aur sahi dimension wali photo hi upload karni padegi.” Yahi kaaran hai ki jab aap UPSC, SSC, RRB ya Passport ka form bharte hain, toh guidelines me saaf likha hota hai ki scan ki gayi photo aur signature 200 DPI ya 300 DPI me hone chahiye. Agar aapki photo 72 DPI ki hui (jo ki aamtaur par mobile camera ki default setting hoti hai), toh portal use verify nahi kar pata aur upload failed ka error aa jata hai.
