Ugoira Animated Image File – file format by pixiv
Ugoira is an animated image file format developed by pixiv that allows for seamless looping of multiple images, creating the effect of an animated GIF. It combines the transparency of PNG with the compression of JPEG to create smaller file sizes while maintaining high image quality.
UGOIRA: Animated PNG Sequences
UGOIRA, short for “Ugo-ugo-ira,” is a file format developed by pixiv for storing animated sequences of PNG images. It combines multiple PNG files into a single container, allowing for animated images to be shared and displayed in a compressed and efficient manner. UGOIRA files retain the transparency and high quality of PNG images, making them ideal for creating animated illustrations, GIFs, and web graphics.
Technical Details and Compatibility
UGOIRA files follow a specific file structure that includes a header and an array of PNG images. The header contains metadata about the animation, such as its frame rate, width, and height. The PNG images are then stored sequentially in the file, each representing a frame of the animation. UGOIRA files can be opened and viewed with various image viewers and web browsers that support animated PNGs, including Pixiv’s own image viewer and Google Chrome. They can also be converted to other animation formats such as GIFs or APNGs.
Opening UGOIRA Files: Software and Platforms
UGOIRA files can be opened using image viewers that support animated images, such as XnView, Honeyview, and IrfanView. These viewers allow users to play the animated sequence and save individual frames as separate image files.
Additionally, UGOIRA files can be opened and played on web browsers that support the APNG (Animated Portable Network Graphics) format, such as Google Chrome, Mozilla Firefox, and Microsoft Edge. APNG is a relatively new image format that allows for the creation and display of animated images similar to UGOIRA.
Converting UGOIRA Files to Other Formats
To convert UGOIRA files to other image formats such as GIF or PNG, users can employ online converter tools like ezgif.com or convertio.co. These tools provide a simple interface to upload and convert UGOIRA files to various image formats, including animated GIFs and individual frames in PNG format.
It’s worth noting that converted GIF or PNG files may not retain the same animation quality as the original UGOIRA file. UGOIRA is specifically optimized for web display and supports higher frame rates and smoother transitions compared to traditional GIF animations.
UGOIRA: Dynamic Animated Art from Pixiv
UGOIRA (pronounced “u-goi-ra”) is a file format developed by pixiv, a renowned Japanese online illustration and manga platform. UGOIRA stands for “Ugoira Animated Image File,” and it is specifically designed for animated images created by artists within the pixiv community. UGOIRA files combine multiple static images into a single animated sequence, allowing artists to showcase their artwork in a dynamic and engaging way.
The UGOIRA file format utilizes a unique compression algorithm that optimizes the size of the animated image while maintaining a high level of visual quality. This compression allows artists to create UGOIRA files with clear and detailed animations, even within the limitations of file size restrictions. Additionally, UGOIRA supports transparency and multiple layers, enabling artists to create complex and visually appealing animations with ease.
