3. Android versiyonlari End Android Kamera API Problemleri Cihaz ve Üretici Çeşitliliği Karmaşık API
4. CameraX nedir? • Daha kolay kamera uygulamaları geliştirmeye yardımcı • Açık kaynak • Alpha
5. Android 5+ End CameraX Tüm köşe senaryolar kapsanmış Arka planda Camera2 API kullanan basit API
6. CameraX • Lifecycle ile uyumlu • Portrait, HDR, Night, ve Beauty • Eklenti alabiliyor
7. CameraX Ön İzleme Görüntü Analizi Görüntü Yakalama
8. Ön İzleme
9. val viewFinderConfig = PreviewConfig.Builder().build()
10. val viewFinderConfig = PreviewConfig.Builder().build() val preview = AutoFitPreviewBuilder.build(viewFinderConfig, viewFinder)
11. val viewFinderConfig = PreviewConfig.Builder().build() val preview = AutoFitPreviewBuilder.build(viewFinderConfig, viewFinder) preview.setOnPreviewOutputUpdateListener { previewOutput -> //use previewOutput.surfaceTexture if needed }
12. val viewFinderConfig = PreviewConfig.Builder().build() val preview = AutoFitPreviewBuilder.build(viewFinderConfig, viewFinder) preview.setOnPreviewOutputUpdateListener { previewOutput -> //use previewOutput.surfaceTexture if needed } CameraX.bindToLifecycle(this, preview)
13. val viewFinderConfig = PreviewConfig.Builder().build() val preview = AutoFitPreviewBuilder.build(viewFinderConfig, viewFinder) preview.setOnPreviewOutputUpdateListener { previewOutput -> //use previewOutput.surfaceTexture if needed } CameraX.bindToLifecycle(this, preview)
14. Görüntü Analizi
15. val imageAnalysisConfig = ImageAnalysisConfig.Builder() .setTargetResolution(Size(1280, 730)) .build()
16. val imageAnalysisConfig = ImageAnalysisConfig.Builder() .setTargetResolution(Size(1280, 730)) .build() val imageAnalysis = ImageAnalysis(imageAnalysisConfig)
17. val imageAnalysisConfig = ImageAnalysisConfig.Builder() .setTargetResolution(Size(1280, 730)) .build() val imageAnalysis = ImageAnalysis(imageAnalysisConfig) imageAnalysis.setAnalyzer { imageProxy, rotationDegrees -> //do image analysis }
18. val imageAnalysisConfig = ImageAnalysisConfig.Builder() .setTargetResolution(Size(1280, 730)) .build() val imageAnalysis = ImageAnalysis(imageAnalysisConfig) imageAnalysis.setAnalyzer { imageProxy, rotationDegrees -> //do image analysis } CameraX.bindToLifecycle(this, imageAnalysis, preview)
19. val imageAnalysisConfig = ImageAnalysisConfig.Builder() .setTargetResolution(Size(1280, 730)) .build() val imageAnalysis = ImageAnalysis(imageAnalysisConfig) imageAnalysis.setAnalyzer { imageProxy, rotationDegrees -> //do image analysis } CameraX.bindToLifecycle(this, imageAnalysis, preview)
20. Görüntü Yakalama
21. val imageCaptureConfig = ImageCaptureConfig.Builder() .build()
22. val imageCaptureConfig = ImageCaptureConfig.Builder() .build() val imageCapture = ImageCapture(imageCaptureConfig)
23. val imageCaptureConfig = ImageCaptureConfig.Builder() .build() val imageCapture = ImageCapture(imageCaptureConfig) CameraX.bindToLifecycle( this, preview, imageCapture, imageAnalyzer)
24. val imageCaptureConfig = ImageCaptureConfig.Builder() .build() val imageCapture = ImageCapture(imageCaptureConfig) CameraX.bindToLifecycle( this, preview, imageCapture, imageAnalyzer)
25. val imageSaveListener = object : ImageCapture.OnImageSavedListener { override fun onImageSaved(file: File) { //use the image file } override fun onError(useCaseError: ImageCapture.UseCaseError, message: String, cause: Throwable?) { //handle error } }
26. val imageSaveListener = object : ImageCapture.OnImageSavedListener { override fun onImageSaved(file: File) { //use the image file } override fun onError(useCaseError: ImageCapture.UseCaseError, message: String, cause: Throwable?) { //handle error } } val photoFile = createFile(outputDirectory, FILENAME, PHOTO_EXTENSION)
27. val imageSaveListener = object : ImageCapture.OnImageSavedListener { override fun onImageSaved(file: File) { //use the image file } override fun onError(useCaseError: ImageCapture.UseCaseError, message: String, cause: Throwable?) { //handle error } } val photoFile = createFile(outputDirectory, FILENAME, PHOTO_EXTENSION) imageCapture.takePicture(photoFile, imageSaveListener)
28. val imageSaveListener = object : ImageCapture.OnImageSavedListener { override fun onImageSaved(file: File) { //use the image file } override fun onError(useCaseError: ImageCapture.UseCaseError, message: String, cause: Throwable?) { //handle error } } val photoFile = createFile(outputDirectory, FILENAME, PHOTO_EXTENSION) imageCapture.takePicture(photoFile, imageSaveListener)
