एक समृद्ध यूआई एप्लिकेशन होने से जिसमें मैं इस तरह की जटिल आकृति के साथ छवि दिखाना चाहता हूं
अब मैं जो चाहता हूं वह मास्क इमेज के अनुसार अपनी छवि को क्रॉप करना है, वास्तव में इमेज डायनामिक आ रही है और इसे कैमरा या गैलरी (स्क्वायर या आयत आकार) से आयात किया जा सकता है और मैं चाहता हूं कि यह इमेज मेरे लेआउट फ्रेम में फिट हो।
तो बस सोच रहा था कि मुझे यह कैसे हासिल होगा? किसी भी विचार / संकेत का स्वागत करते हैं
बैकग्राउंड फ्रेम
