I am using getRotatedImage function of ImageUtil class of apache pdfbox library to rotate a Buffered Image. The output is perfectly rotated image provided with Buffered image and degree of rotation. The only problem is that the output image when converted to pdf is more than double the size of original image, i.e 1.7MB image is converted to 4.3MB pdf.

When I save a image from a picturebox using Picturebox1.Image.Save, the saved image size is much larger than the original image size (for example, from 1.5 MB to 15 MB). What can I do for the image will be saved in the same size of the original image?
Thank you in advance.
You probably load a JPEG or PNG image into the Picturebox, which are compressed file formats. However Picturebox1.Image.Save saves it as a bitmap, if you do not specify the type. Bitmaps are uncompressed and therefore quite large. You can change this by using
Picturebox1.Image.Save(Outputfilename, Drawing.Imaging.Imageformats.Png)
This saves the image in the PNG-Format, which is much smaller.
