Vector graphics tutorials edit

Application edit

• SVG with Inkscape - Fully featured SVG drawing program, also capable of PNG output
• Using Dia - page not maintained - Well suited to technical diagrams & flowsheets - PNG output, limited SVG support
• Using Microsoft Word - page not maintained - Familiar to many users, easy to use - PNG only, no SVG support

Specific tasks edit

• How to create graphs for Wikipedia articles
• Displaying a formula with commutative diagrams in TeX, in mathematics
• How to draw SVG circuits using Xcircuit, in electronics

Bitmap graphics tutorials edit

• Wikipedia:Basic bitmap image editing
• Wikipedia:Graphic Lab/Optimizing relief - map-making tutorial using 3DEM or GRASS GIS editors and GIMP bitmap editor (all free programs)

Photo editing tutorials edit

• How to improve image quality

Combination tutorials edit

• Picture tutorial: The best way to add your pictures to articles
• Maps and images for Wikipedia
• Coloring cartographic maps
• Keep in mind that images can contain hidden data and that you might want to remove the hidden data before publishing the images.
• Text can be overlaid onto images using Template:Annotated image or Template:Annotated image 4.

Filesize optimisation tutorials edit

• Wikipedia:Preparing images for upload - Describes how to keep image file sizes as small as possible.
• How to reduce colors for saving a JPEG as PNG (using The GIMP)

Open source programs edit

• pngquant - program that reduces PNG size by automatically reducing the number of colors. Visually lossless most of the time.
• PNGCrush - Old tried and true program that reduces PNG sizes using multiple zlib compression trials on disk.
• OptiPNG - Essentially a newer version of PNGCrush, it economizes the trial (reducing from 100s of short ones to a maximum of 7 longer ones) and does everything in memory. Usually produces identical results, and is much faster.
• AdvanceCOMP - A group of programs designed to reduce ZIP compression in many contexts, including PNGs (using AdvPNG).
• Jhead - A program for viewing, altering, or removing Exif data of JPEGs. Amongst other things, this allows for reducing file sizes.
• FileOptimizer - A Windows GUI program (recommended for beginners) that uses multiple open source and freeware tools (including most of those listed here) to optimize a large number of media filetypes. Achieves better compression than any of the others used by themselves. Released under the LGPL.

Freeware programs edit

• PNGOUT - A program that optimizes PNGs by eschewing the usual zlib compression for a slower but more complete algorithm.
  • PNG Gauntlet - GUI for OptiPNG, PNGOUT, and DeflOpt (similar to AdvPNG in AdvanceCOMP)
• Image Analyzer - Amongst other things, allows for lossy compression of PNG files. (Often, however, merely posterizing the image at a level that does not produce color banding results in smaller files of the same or higher quality.)
• JPG Cleaner - Removes Exif data from JPEGs, making the files smaller.
• JPGExtra and PNGExtra - Programs that losslessly optimize JPEGs and PNGs by cleanly removing all non-image data.
