[Color] AnimatedImage tinting not getting applied

[Boowman]

Hello,

I am trying to apply a tint to an svg image but it seems no matter what I try none of them work.
I have already tried applying each modifier individually but I just wanted to show what I have tried.

Device

• iPhone 15 Prox Max
• iOS 17.5

AnimatedImage(url: <svg_url>)
    .resizable()
    .renderingMode(.template)
    .onViewCreate(perform: { view, image in
        view
            .tintColor = .green
    })
    .tint(.green)
    .accentColor(.green)
    .foregroundStyle(.green)
    .colorMultiply(.green)
    .frame(width: 32, height: 32)

Seems you want that UIKit imageView to apply tintColor.

I can have a check whether the SDAnimatedImageView supports tint color. Because it's a custom subclass image view from UIImageView, not all of the UIImageView static image rendering is supported😂

[Boowman]

If you could let me know if it supports tinting it would be great. In terms of implementation, I went based on what I found in the documentation that was provided which surprised me that it doesn't work. Scroll to Animated Image

This weekend I'll have a test and check.

Currently SDAnimatedImage use custom rendering on animated image (which means, we override CALayer's content by ourselves), but only re-use the UIKit rendering on static image.

I guess this cause the root issue. We need to implements each special UIImageView rendering (like renderingMode, tintColor, resizableImage) on animated image (or find a better way to magically re-use the UIKit implementation)

@Boowman Can you have a test on WebImage ? Which use normal SwiftUI rendering (actually it's simple on concept, just dynamic change the body based on Timer, to return new SwiftUI.Image)

[Boowman]

@dreampiggy I tested WebImage and it works when applying tint, the problem with this is that it if I use it within an animated context which is what I am doing at the moment. It doesn't animate, it seems to be fixed on the page and the content animates around it.

Can you provide a real demo with these 2 use case ? It seems both of them contains issue.

1. AnimatedImage with tint on animated image url
2. WebImage with tint on animated image url

But SVG is not animtable, so it's a little strange in your demo. I use a APNG and WebP image for showing

I was looking to create a quick demo showing the usage but the SVG are not even loading, here is a screenshot and the full-code in case you want to test it.

import SwiftUI
import SDWebImage
import SDWebImageSwiftUI

struct ContentView: View {
    @State var fadeInContent: Bool = false
        
    var body: some View {
        ScrollView {
            VStack {
                LazyVGrid(columns: [.init(), .init()], content: {
                    VStack {
                        Text("No tinting")
                            .foregroundStyle(.white)
                        
                        AnimatedImage(url: URL(string: "https://www.svgrepo.com/show/194550/online-shop.svg")!)
                            .resizable()
                            .scaledToFit()
                            .frame(width: 64, height: 64)
                            .clipped()
                            .background(.gray)

                            .background(.gray)
                    }
                    VStack {
                        Text("With tinting")
                            .foregroundStyle(.white)

                            .tint(.red)
                            .scaledToFit()

                    .offset(y: 50)
                    .opacity(fadeInContent ? 1 : 0)
                    .offset(y: fadeInContent ? -50 : 0)
                })
            }
            .padding()

        .background(.black)

Is this what you want ?

So if not AnimatedImage what would you use to load SVG ??

WebImage can support SVG. It will draw bitmap version (fixed size) instead of Pure Vector Format

See why I introduce this code:
https://github.com/SDWebImage/SDWebImageSwiftUI/blob/master/SDWebImageSwiftUI/Classes/WebImage.swift#L200-L217

And, you can run SwiftUI Demo in our repo to check, which shows 2 URL of SVGs

[dreampiggy]

but the SVG are not even loading

SVG is not official supported by Apple's ImageIO coder. It's not a normal bitmap image format

You need that https://github.com/SDWebImage/SDWebImageSVGCoder

Oh yes, i forgot to add this in the sample project.

I will make the demo and post it here, sorry it's been taking so long.
