Action Performed:

1. Sent a long image in a chat.
2. Closed the chat window.
3. Reopened the chat window containing the sent long image.
4. Observed the loading spinner that appears while the image is still loading.

Expected Result:

The loading spinner should be fully visible and centered on the screen while the long image is still loading after reopening the chat window. The thumbnail should be capped at a maximum height and minimum width so that the loading spinner is displayed properly.

Actual Result:

The loading spinner is cut off on both the left and right sides, with only a small portion of the spinner visible.

Workaround:

Can the user still use Expensify without this being fixed? Have you informed them of the workaround?

Proposal

Please re-state the problem that we are trying to solve in this issue.

Loading spinner is cut off on long images when reopening the chat

What is the root cause of that problem?

The problem arises due to the aspect ratio of long images, which is causing the thumbnailScreenWidth to become narrower than the width of the spinner.

What changes do you think we should make in order to solve the problem?

Solution A

We can cap the max-height and limit the min-width of the thumbnail by updating this function

App/src/components/ThumbnailImage.js

Lines 55 to 76 in f8acfae

	calculateThumbnailImageSize(width, height) {
	if (!width || !height) {
	return {};
	}
	// Width of the thumbnail works better as a constant than it does
	// a percentage of the screen width since it is relative to each screen
	// Note: Clamp minimum width 40px to support touch device
	let thumbnailScreenWidth = lodashClamp(width, 40, 250);
	const imageHeight = height / (width / thumbnailScreenWidth);
	let thumbnailScreenHeight = lodashClamp(imageHeight, 40, this.props.windowHeight * 0.40);
	const aspectRatio = height / width;
	// If thumbnail height is greater than its width, then the image is portrait otherwise landscape.
	// For portrait images, we need to adjust the width of the image to keep the aspect ratio and vice-versa.
	if (thumbnailScreenHeight > thumbnailScreenWidth) {
	thumbnailScreenWidth = Math.round(thumbnailScreenHeight * (1 / aspectRatio));
	} else {
	thumbnailScreenHeight = Math.round(thumbnailScreenWidth * aspectRatio);
	}
	return {thumbnailWidth: thumbnailScreenWidth, thumbnailHeight: Math.max(40, thumbnailScreenHeight)};
	}

Which is responsible to calculate Thumbnail ImageSize ,thumbnailScreenWidth and thumbnailScreenHeight to this

    calculateThumbnailImageSize(width, height) {
        if (!width || !height) {
            return {};
        }
        // Width of the thumbnail works better as a constant than it does
        // a percentage of the screen width since it is relative to each screen
        // Note: Clamp minimum width 40px to support touch device
        let thumbnailScreenWidth = lodashClamp(width, 40, 250);
        // alert(thumbnailScreenWidth);
        let imageHeight = height / (width / thumbnailScreenWidth);
        let thumbnailScreenHeight = lodashClamp(imageHeight, 40, this.props.windowHeight * 0.40);
        let aspectRatio = height / width;

        // If thumbnail height is greater than its width, then the image is portrait otherwise landscape.
        // For portrait images, we need to adjust the width of the image to keep the aspect ratio and vice-versa.
        
        
        if (thumbnailScreenHeight > thumbnailScreenWidth) {
        //Checking if the aspect ratio of image does not cause the value of thumbnailScreenWidth to fall below the minimum width.
            if(Math.round(thumbnailScreenHeight * (1 / aspectRatio))<80){
                thumbnailScreenWidth = 80;
                thumbnailScreenHeight = 80*aspectRatio;
                // Capping the maximum height of the thumbnail 
                if (thumbnailScreenHeight>500){
                    thumbnailScreenHeight = 500;
                }
            }
            else{
            thumbnailScreenWidth = Math.round(thumbnailScreenHeight * (1 / aspectRatio));
           }
        } else {
            
            thumbnailScreenHeight = Math.round(thumbnailScreenWidth * aspectRatio);
        }
        return {thumbnailWidth: thumbnailScreenWidth, thumbnailHeight: Math.max(40, thumbnailScreenHeight)};
    }

and then we can change resize mode from contain to cover here

App/src/components/ImageWithSizeCalculation.js

Line 85 in 4fefc48

resizeMode={Image.resizeMode.contain}

 resizeMode={Image.resizeMode.cover}

Solution B

We can cap the max height here

App/src/components/ThumbnailImage.js

Line 90 in 6f6cf65

<View style={[this.props.style, styles.overflowHidden]}>

by adding a new style maxHeight like this

 <View style={[this.props.style, styles.overflowHidden , {maxHeight:400}]}> //we can add a new style in stylesheet for this 

and since the aspect ratio of long images causes the width of the thumbnail to fall below the width of spinner, we can simply check if thumbnailScreenWidth is less than the desired min with (or width of spinner) and if so we can change it in the function
calculateThumbnailImageSize to our desired min with

and then to make the image fill the entire area of the thumbnail and be centered, we can simply set image resize mode to cover. To do this we can change this line

App/src/components/ImageWithSizeCalculation.js

Line 85 in 6f6cf65

resizeMode={Image.resizeMode.contain}

to this

 resizeMode={Image.resizeMode.cover}

Result

Both solutions will give us same result

I think we should also check and set cap on min-height and Max width of the thumbnail when it is in landscape mode
