Why CelesteCS?

We make easy to use products empowered by complex technologies

Lossless JPEG Rotation

Lossless JPEG Rotation

JPEG images are stored as a number of independently encoded rectangular blocks called Minimum Coded Units (MCU). MCUs can be rotated in 90 degree steps without having to be decompressed into a bitmap and re-compressed back to a JPEG. This feature is used in CelesteCS Rotator to rotate JPEG images in 90 degree steps without loss in quality.


Reverse Polish Notation

Reverse Polish Notation is a mathematical notation in which every operator follows all of its operands. In computer science, postfix notation is often used in stack-based and concatenative programming languages. We use this technology in CelesteCS Math product to evaluate formulas.

EXIF, IPTC and XMP Metadata

EXIF, IPTC and XMP Metadata

EXIF, IPTC and XMP are the standards that specify the formats for images, sound, and ancillary tags used by digital cameras (including smartphones). Information such as the photographer name, geolocation, copyright can be embedded into JPEG files with this standard. CelesteCS Rotator preserves this information during rotating images.

Automatic Image Rotation

Automatic JPEG Rotation

EXIF standard defines an Orientation Tag to indicate the orientation of the camera relative to the captured scene. This is often used by the camera either to indicate the orientation automatically by an orientation sensor, without actually transforming the image data itself. This results in wrong orientation of images in some browsers. CelesteCS Rotator helps to fix it.
