मैं एसवीजी में समग्र संचालन विकसित करने की कोशिश कर रहा हूं। मुझे एसवीजी में समग्र ऑपरेशन को लागू करने के लिए कोड नीचे मिला, लेकिन जब मैं एक ही उदाहरण लागू कर रहा हूं तो मुझे आउटपुट में समग्र ऑपरेशन नहीं मिल रहा है। मैंने इस कोड को codepen.io में परीक्षण करने और यह आउटपुट। और मेरी इच्छा आउटपुट यहां है

मुझे यह उदाहरण कोड यहां से मिला है।

मुझे एक और कोड मिला जो समग्र संचालन के लिए भी काम नहीं कर रहा है। यहां नीचे दिए गए कोड का डिजाईन आउटपुट है।

सबसे बढ़िया उत्तर

मुझे पूरा यकीन नहीं है कि आप यही उम्मीद कर रहे हैं। यह मेरा समाधान है: मैं एक फ़िल्टर बना रहा हूँ जहाँ मैं in विशेषता के लिए बाढ़ वाले आयत का उपयोग कर रहा हूँ और in2 विशेषता के लिए स्रोत ग्राफ़िक का उपयोग कर रहा हूँ। मैं जिस ऑपरेटर का उपयोग कर रहा हूं वह atop जैसा आप चाहते हैं।
