hi! same here, any workaround?

I was able to capture a long image using the option useRenderInContext

@tomaseliasm I can see that in the documentation, but in the latest version 3.4.0 It doesn’t exists. This is the interface to CaptureOptions

export interface CaptureOptions {
        /**
         * (number): the width and height of the final image (resized from the View bound. don't provide it if you want
         * the original pixel size).
         */
        width?: number;
        /**
         * @see {CaptureOptions#width}
         */
        height?: number;
        /**
         * either png or jpg or webm (Android). Defaults to png. raw is a ARGB array of image pixels.
         */
        format?: 'jpg' | 'png' | 'webm' | 'raw';
        /**
         * the quality. 0.0 - 1.0 (default). (only available on lossy formats like jpg)
         */
        quality?: number;
        /**
         * the method you want to use to save the snapshot, one of:
         " - tmpfile" (default): save to a temporary file (that will only exist for as long as the app is running).
         " - base64": encode as base64 and returns the raw string. Use only with small images as this may result of
         *   lags (the string is sent over the bridge). N.B. This is not a data uri, use data-uri instead.
         " - data-uri": same as base64 but also includes the Data URI scheme header.
         " - zip-base64: compress data with zip deflate algorithm and than convert to base64 and return as a raw string."
         */
        result?: 'tmpfile' | 'base64' | 'data-uri' | 'zip-base64';
        /**
         * if true and when view is a ScrollView, the "content container" height will be evaluated instead of the
         * container height.
         */
        snapshotContentContainer?: boolean;
    }
