Description	🔵 The JPEG (.jpg .jpeg) format, was developed by the Joint Photographic Experts Group—hence the name. It’s the standard file for storing and sharing digital photos, especially the ones taken with your camera. The way it works is by using lossy compression. This shrinks the file size a lot, but you should know it sacrifices some image data along the way. It’s always a balance: you trade a little bit of quality for a much smaller file that’s easier to send.
Technical details	🔵 Los archivos DWG lo que hacen es guardar datos de imagen vectorial y también metadatos, y todo eso normalmente está codificado en binario. Cuando abres un DWG, lo que realmente ves es el resultado de todas esas instrucciones codificadas. Los archivos que salen de AutoCAD se suelen verificar para confirmar que son correctos y válidos. Ahora, si no quieres comprar AutoCAD, hay software gratis como Autodesk DWG Trueview. Ojo, este no trae el TrueConvert, pero te permite ver los archivos, medir cosas, hacer anotaciones, organizar planos y ver cómo va el progreso. Luego tienes programas como DraftSight, que sí te dejan crear, editar y ver los DWG. Y hay un proyecto, LibreDWG, que está trabajando en hacer bibliotecas de código abierto para este formato, porque la verdad es que escasean los visores gratuitos.

Description	🔵 The Portable Any Map (PNM) format is a collection of image file formats designed for portable images. Each image essentially represents a pixel value map that can encode data in grayscale or color. There are three main types of files in the PNM format family: Portable BitMap (PBM), Portable GrayMap (PGM), and Portable PixMap (PPM).
Technical details	🔵 PBM format uses binary pixel data. Each pixel is represented by a single bit, where 0 indicates black and 1 represents white. The pixel data for each row is organized as a bit sequence, padded to a full byte. Conversely, the PGM format handles grayscale pixel data. It represents each pixel with a single byte. The pixel data is arranged in rows, with each row of pixel data grouped together. PPM format deals with color pixel data. Each pixel is represented by three bytes, each indicating the red, green, and blue components of a color. This pixel data is also organized in rows, with each row grouped together and represented by sets of three bytes. Finally, note that PNM files can be easily converted between these three formats. Furthermore, specific software tools can convert PNM files to other image file formats, and vice versa.
