Now you must set the width and height of the picture. Can you add a choice to make it use the original width and height.

CreateImageFromPDF.kt

fun create(path: String?, outputDirPath: String?, maxWidth : Int?, maxHeight : Int? , createOneImage : Boolean?)

// val bitmap: Bitmap = page.renderBitmap(maxWidth!!, maxHeight!!, rectF) val bitmap: Bitmap = page.renderBitmap(page.width, page.height, rectF) //use original width and height.

Or scale the picture according to the maximum width and height as IOS. public static func resizeImage(img: UIImage, maxWidthGet : Int, maxHeightGet : Int) -> UIImage { var actualHeight: Float = Float(img.size.height) var actualWidth: Float = Float(img.size.width) let maxHeight: Float = Float(maxHeightGet) let maxWidth: Float = Float(maxWidthGet) var imgRatio: Float = actualWidth / actualHeight let maxRatio: Float = maxWidth / maxHeight // let compressionQuality: Float = 0.5 //50 percent compression

    if actualHeight > maxHeight || actualWidth > maxWidth {
        if imgRatio < maxRatio {
            //adjust width according to maxHeight
            imgRatio = maxHeight / actualHeight
            actualWidth = imgRatio * actualWidth
            actualHeight = maxHeight
        }
        else if imgRatio > maxRatio {
            //adjust height according to maxWidth
            imgRatio = maxWidth / actualWidth
            actualHeight = imgRatio * actualHeight
            actualWidth = maxWidth
        }
        else {
            actualHeight = maxHeight
            actualWidth = maxWidth
        }
    }

    let rect = CGRect(x: 0.0, y: 0.0, width: CGFloat(actualWidth),  height: CGFloat(actualHeight))

    let newSize = AVMakeRect(
        aspectRatio: img.size,
        insideRect: rect
     ).size

// UIGraphicsBeginImageContext(rect.size)

    UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0)
    img.draw(in: CGRect(origin: .zero, size: newSize))
    let scaled = UIGraphicsGetImageFromCurrentImageContext() ?? img
    UIGraphicsEndImageContext()

// img.draw(in:rect) // let img = UIGraphicsGetImageFromCurrentImageContext() // let imageData = img?.jpegData(compressionQuality: CGFloat(compressionQuality)) // UIGraphicsEndImageContext() return scaled }
