TYPO3 Extension imageopt

This extension allows to optimize images resized by TYPO3 so they will take less space. TYPO3 services are used to register the providers of images optimization so own providers can be registered also. Cron based.

Support native linux commands like:

• Png format:
  • optipng
  • pngcrush
  • pngquant
• Gif format:
  • Gifsicle
• Jpeg format:
  • jpegoptim
  • jpegrescan
  • jpegtran
  • mozjpg

Support for several remotes:

• Kraken (https://kraken.io/)
• Tinypng (https://tinypng.com/)
• Imageoptim (https://imageoptim.com/api)

Installation

Install the extension using composer composer require sourcebroker/imageopt.

Configuration

Default configuration is read automaticly:

tx_imageopt {

    directories =

    default {
    
        limits {
            notification {
                sender {
                    email =
                    name =
                }
                reciver {
                    email =
                    name =
                }
                disable = 0
            }
        }
        
        providers {
            
            kraken {
                apikey =
                apipass =
                enabled = 0
                limits < tx_imageopt.default.limits
                options {
                    lossy = true
                }
            }
            tinypng {
                apikey =
                apipass =
                enabled = 0
                limits < tx_imageopt.default.limits
            }
            imageoptim {
                apikey =
                apipass =
                enabled = 0
                limits < tx_imageopt.default.limits
                options {
                    lossy = true
                }
            }
        }
    }

    providers {

        jpg {
            kraken < tx_imageopt.default.providers.kraken

            tinypng < tx_imageopt.default.providers.tinypng

            imageoptim < tx_imageopt.default.providers.imageoptim

            jpegoptim {
                command = {executable} {tempFile} -o
                enabled = 1
            }

            jpegrescan {
                command = {executable} {tempFile} {tempFile}
                enabled = 1
            }

            jpegtran {
                command = {executable} -copy none -optimize -progressive -outfile {tempFile} {tempFile}
                enabled = 1
            }

            mozjpg {
                command = {executable} -copy none {tempFile} > {tempFile}
                enabled = 1
            }
        }

        gif {

            tinypng < tx_imageopt.default.providers.tinypng

            imageoptim < tx_imageopt.default.providers.imageoptim

            gifsicle {
                command = {executable} --batch --optimize=3 {tempFile}
                enabled = 1
            }
        }

        png {
            kraken < tx_imageopt.default.providers.kraken

            tinypng < tx_imageopt.default.providers.tinypng

            imageoptim < tx_imageopt.default.providers.imageoptim

            optipng {
                command = {executable} {tempFile}
                enabled = 1
            }

            pngcrush {
                command = {executable} -q -rem alla -brute -reduce -ow {tempFile} >/dev/null
                enabled = 1
            }

            pngquant {
                command = {executable} {tempFile} --force --ext ''
                enabled = 1
            }
        }
    }
}

As you see above, by default, only linux native commands are enabled.

If you would like to run only Kraken.io then put this config in you PageTS.

tx_imageopt {

    default {
    
        limits {
            notification {
                sender {
                    email = [email protected]
                    name = Admin
                }
                reciver {
                    email = [email protected]
                    name = Admin
                }
                disable = 1
            }
        }
            
        kraken {
            apikey = 9d41f741e4df359db85936865e3afaaa
            apipass = df666c5ea90490b0f1ce2b473bdb6ba9bd1f903f
            enabled = 1
            limits < tx_imageopt.default.limits
        }
    }

    providers {
        jpg >
        jpg {
            kraken < tx_imageopt.default.providers.kraken
        }
        gif >
        gif {

        png >
        png {
            kraken < tx_imageopt.default.providers.kraken
        }
    }
}

Technical notes

• The original images, for example in folder fileadmin/, uploads/ are not optmized. Only already resized images are optmized, so for FAL that would be files form "_processed_/" folder of file storages.
• Be aware that there are two xclasses to make TYPO3 to process images even if there is no need (because for example the requested image size is the same as original). Thanks to that xclasses the original images do not have to be optimized.
• For FAL files only file that are in "sys_file_processedfile" are optimized. Table "sys_file_processedfile" has been extended with "tx_imageopt_optimized" field. If file has been optimised then the field "tx_imageopt_optimized" is set to 1. You can reset the "tx_imageopt_optimized" flag with command php ./typo3/cli_dispatch.phpsh extbase imageopt:resetoptimizationflag
• If you enable more than one image optimizer provider then all runs and the best optimized image is choosed.
• There is table "tx_imageopt_images" where the statistics and winning image optmimizer is stored.

Usage

1. Direct cli call: php ./typo3/cli_dispatch.phpsh extbase imageopt:optimizeimages
2. Or better create extbase scheduler job in TYPO3 backend to run task regularly.
