Hi,

Getting error while saving image after resizing. It works for jpg images and other png files. Java.

Code

        // THUMB_WIDTH = 400 - any value for attached image
        com.aspose.imaging.Image image = com.aspose.imaging.Image.load(inputStream);
        double k = (double) image.getWidth() / (double) THUMB_WIDTH;
        image.resize(THUMB_WIDTH, (int) (image.getHeight() / k));
        image.save(outputStream);
        image.close();

Exception

com.aspose.imaging.internal.Exceptions.ArgumentNullException: Value cannot be null.

Hi, @Ytrohs
While we analyze this issue you can avoid this issue using Image.getOriginalOptions()

// THUMB_WIDTH = 400 - any value for attached image
com.aspose.imaging.Image image = com.aspose.imaging.Image.load(inputStream);
double k = (double) image.getWidth() / (double) THUMB_WIDTH;
image.resize(THUMB_WIDTH, (int) (image.getHeight() / k));
ImageOptionsBase options = image.getOriginalOptions();
if (options != null)
{
	options = options.deepClone();
}
image.save(outputStream, options);
image.close();
