bufferedimage

I have snippet of code that I am using for the purpose of resizing an image to a curtain size (I want to change the resolution to something like 200 dpi). Basically the reason I need it is because I want to display the image that the user have picked (somewhat large) and then if the user approves I want to display the same image in a different place but using a smaller resolution. Unfortunately, if I give it a large image nothing appears on the screen. Also, if I change imageLabel.setIcon(newIcon); to imageLabel.setIcon(icon); I get the image to display but not in the correct resolution that's

I am uploading images using servlet. To perform resize operations i am converting InputStream to BufferedImage. Now i want to save it in mongoDB. Since, i am new to mongoDB as far as i know, GridFS takes InputStream. So, is there any way to convert BufferedImage to InputStream? You need to save the BufferedImage to a ByteArrayOutputStream using the ImageIO class , then create a ByteArrayInputStream from toByteArray() . First of all you must get your "bytes": byte[] buffer = ((DataBufferByte)(bufferedImage).getRaster().getDataBuffer()).getData(); And then use ByteArrayInputStream(byte[] buf)

I have a servlet based application that is serving images from files stored locally. I have added logic that will allow the application to load the image file to a BufferedImage and then resize the image, add watermark text over the top of the image, or both. I would like to set the content length before writing out the image. Apart from writing the image to a temporary file or byte array, is there a way to find the size of the BufferedImage? All files are being written as jpg if that helps in calculating the size. No, you must write the file in memory or to a temporary file. The reason is

How can I make an image border as gradient. I googled a lot, but didn't find correct suggestion. Any one can help me... Any suggestion please... This is an interesting one. I first thought that there should be a simple solution, using some Graphics#drawRoundRect call with the appropriate Paint , but it's not sooo simple. However, one solution is implemented in the following example: The image is painted as-it-is into a new image. Then the edges and corners are painted. These consist of rectangles. Each rectangle for one edge is filled with a GradientPaint that interpolates between "completely
