. نوشتن بصورت Landscape رو هم با 2تا کار انجام دادم اول کدهای هگز فایل فونت رو دستکاری کردم و کاراکترها رو چرخوندم به اندازه 90 درجه به چپ. کار دومم هم این بود که تو تابعی که رشته رو چاپ می کرد بجای اینکه y رو زیاد کنه و کاراکتر بعدی رو بنویسه گفتم x رو زیاد کنه در نتیجه شروع کرد عمودی نوشتن شکل کاراکترا رو هم که چرخونده بودم در نتیجه مشکل حل شد. اینا رو گفتم شاید بدرد دوستانم بخوره :wow: :nerd: :applause: :job:
