ImageIO.write( resizedImage, "png", baos ) Īnd this is the resizeImage function: public BufferedImage resizeImage(BufferedImage image, String extension, int targetWidth, int targetHeight) while (w != targetWidth || h != targetHeight) ("dimensiuni:" + resizedImage.getHeight()+ "x" + resizedImage.getWidth()) īyteArrayOutputStream baos = new ByteArrayOutputStream()
This is how I do it: BufferedImage resizedImage = resizeImage(image,extension,width,height) I couldn't find any library or solution for this problem. I'm trying to find a way to compress the png, to have a smaller size, without reducing the quality.
This is not a solution for me, because the images are stored in the database as BLOBs and the website loads slower. If I upload a 200 kb image, after cropping and making it PNG it has 600 kb. The problem I'm having is the picture size. jks keystore file as a backup before deleting the certificate.I'm working on a website that allows users to upload images and crop them. It is recommended to take a copy of your cacerts or. jks file use the following command C:\ Program Files\ Java\jdk1.8\bin>keytool -delete -alias certificate1.cer -keystore keystorefilename.jks Or use with the -storepass option, keytool -delete -alias certificate1.cer -keystore cacerts -storepass keywordpasswordhereĭelete Certificate 2 C:\ Program Files\ Java\jdk1.8\bin>keytool -delete -alias certificate2.cer -keystore cacerts Let it prompt for entering your keystore password.ĭelete Certificate 1 keytool -delete -alias certificate1.cer -keystore cacerts It is the recommended approach instead of adding the password to the command. We haven't used the -storepass keyword, but on entering the delete command it will prompt for the storepass keystore password. Syntax keytool -delete -alias certificatealiasname -keystore cacerts Using the keytool delete command, the certificates can be removed one by one using their alias name. Sometimes you might have added a certificate by mistake. We can delete certificates from the Cacerts Keystore file. The certificates are stored with alias names. We saw how to import and list certificates.
