MacroFusion is a neat little GUI for great tool Enfuse (command line). It makes easy fusion few photos to one with great DOF (Deep of Field) or DR (Dynamic Range). It can be useful for every macro lovers or landscapers.

A set of Python scripts, for use with Blender that will export to Java XML, which can be decoded with the standard java.beans.XMLDecoder class. [No longer writes source code; this is a better solution.]

Convert between various image, audio and video formats using the context menu. The addon is written in Python and available for Nautilus, Nemo, Thunar and Dolphin file viewers. It adds a new option to the context menu to create an easy way to convert between a huge amount of file types. The program offers many options to customize the appearance of its context menu. There are also a few extra formats which can be added by installing optional dependencies. The tool has a built-in auto-update function to make sure the newest version is always installed.

SVGMath is a command-line utility to convert MathML expressions to SVG, written entirely in Python.

The littleutils include duplicate file finders (repeats, repeats.pl, repeats.py), image optimizers (opt-jpg, opt-png, opt-gif, recomp-jpg), file rename tools (lowercase, uppercase, pren), archive recompressors (to-gzip, to-bzip2, to-bzip3, to-7zip, to-lzma, to-lzip, to-xz), a tempfile utility (tempname), file property tools (filedate, filemode, filenode, fileown, filesize, and lrealpath), and others. See the README file for more details.

SoundConverter is the leading audio file converter for the GNOME Desktop. It reads anything GStreamer can read, and writes WAV, FLAC, MP3, AAC and Ogg Vorbis.

imgp is a command line image resizer and rotator for JPEG and PNG images. If you have tons of images you want to resize adaptively to a screen resolution or rotate by an angle using a single command, imgp is the utility for you. It can save a lot on storage too. Powered by multiprocessing, an intelligent adaptive algorithm, recursive operations, shell completion scripts, EXIF preservation (and more), imgp is a very flexible utility with well-documented easy to use options. imgp intends to be a stronger replacement of the Nautilus Image Converter extension, not tied to any file manager and way faster. On desktop environments (like Xfce or LxQt) which do not integrate Nautilus, imgp will save your day.

Bulk Image Optimizer and Converter (Portable Executable) It allows users to choose the output format (JPEG, PNG, or WebP), set the desired image quality, and remove EXIF data. The optimized images are saved in a separate folder named "optimized" within the input folder. The tool displays progress information, including the number of images processed, the average compression ratio, and the total space saved.

'GIF Maker' is an desktop application developed using python 3.6.8 and other add-on libaries. Can generate GIF from pictures. Compatible only for windows OS.

The Scientific Visualization Artist Tools (SVAT) include converters from the Visualization Toolkit (VTK) to RenderMan Interface Bytestream (RIB) (ASCII and binary files supported), Blender to RenderMan, compilable RenderMan shaders and other utilities.

Acará is an easy-to-use DVD creator for Unix* build with PyQt4

Generates a texture atlas from a series of input textures.

Batch Image Processor This simple Command line utility allows you to process (ie scale, rotate, change format/quality) a collection of image files. This arose from my need to find a simple way to reduce photos for emailing to family and friends.
