Usage

Local Image:

The image parameter accepts Binding<Image> in all versions. As of 1.0.20, it also accepts Binding<Image?>


                                              
                                                import ImageViewer
 
struct ContentView: View {
@State var showImageViewer: Bool = true
@State var image = Image(“example-image”)
 
var body: some View {
VStack {
Text(“Example!”)
}
.frame(maxWidth: .infinity, maxHeight: .infinity)
.overlay(ImageViewer(image: self.$image, viewerShown: self.$showImageViewer))
}
}

Remote Image:

The imageURL parameter accepts Binding<String>


                                              
                                                import ImageViewerRemote

struct ContentView: View {
    @State var showImageViewer: Bool = true
    @State var imgURL: String = “https://…”

    var body: some View {
        VStack {
            Text(“Example!”)
        }
.frame(maxWidth: .infinity, maxHeight: .infinity)
        .overlay(ImageViewerRemote(imageURL: self.$imgURL, viewerShown: self.$showImageViewer))
    }
}

Customization

close Button Position

Availability: 2.2.0 or higher

The close button can be moved to the top right if desired. The closeButtonTopRight parameter accepts bool.

Example:


                                              
                                                import ImageViewer
struct ContentView: View {

@State var showImageViewer: Bool = true

@State var image = Image(“example-image”)
var body: some View {

VStack {

Text(“Example!”)

}

.frame(maxWidth: .infinity, maxHeight: .infinity)

.overlay(ImageViewer(image: self.$image, viewerShown: self.$showImageViewer, closeButtonTopRight: true))

}

}

Caption

Availability: 2.1.0 or higher

A caption can be added to the image viewer. The caption will appear near the bottom of the image viewer (if the image fills the whole screen the text will appear on top of the image). The caption parameter accepts Text.

Example:


                                              
                                                import ImageViewer
 
struct ContentView: View {
@State var showImageViewer: Bool = true
@State var image = Image(“example-image”)
 
var body: some View {
VStack {
Text(“Example!”)
}
.frame(maxWidth: .infinity, maxHeight: .infinity)
.overlay(ImageViewer(image: self.$image, viewerShown: self.$showImageViewer, caption: Text(“This is a caption!”)))
}
}

Explicit Aspect Ratio

Availability: 1.0.21 or higher

An explcit image aspect ratio can be specified, which fixes an issue of incorrect stretching that occurs in certain situations. The aspectRatio parameter accepts Binding<CGFloat>

Example:


                                              
                                                import ImageViewer

struct ContentView: View {
    @State var showImageViewer: Bool = true
    @State var image = Image(“example-image”)

    var body: some View {
        VStack {
            Text(“Example!”)
        }
.frame(maxWidth: .infinity, maxHeight: .infinity)
        .overlay(ImageViewer(image: self.$image, viewerShown: self.$showImageViewer, aspectRatio: .constant(2)))
    }
}

Disable Cache

Availability: 1.0.25 or higher

To disable cache on the remote image viewer, simply pass a Bool value to the disableCache parameter

Example:


                                              
                                                import ImageViewerRemote

struct ContentView: View {
    @State var showImageViewer: Bool = true

    var body: some View {
        VStack {
            Text(“Example!”)
        }
.frame(maxWidth: .infinity, maxHeight: .infinity)
        .overlay(ImageViewerRemote(imageURL: URL(string: “https://…”), viewerShown: self.$showImageViewer, disableCache: true))
    }
}
