Escrevivendo e Photoandando por ali e por aqui

“O que a fotografia reproduz no infinito aconteceu apenas uma vez: ela repete mecanicamente o que não poderá nunca mais se repetir existencialmente”.

Roland Barthes


«Ao lermos uma novela ou uma história imaginamos as cenas, a paisagem, os personagens, dando a estes uma voz, uma imagem física. Por isso às vezes a transposição para o cinema revela-se-nos uma desilusão. Quando leio o que a Maria do Mar me escreve(u) surge perante mim a sua imagem neste ou naquele momento da nossa vida, uma pessoa simples, encantadora, gentil e delicada.»

License Proprietary, Freeware (for non-commercial use)
IrfanView is a freeware image viewer for Microsoft Windows that can view, edit, and convert image files and play video/audio formats. It does not have extensive image creation and painting capabilities like Adobe Photoshop, Paint.NET or GIMP. Rather, IrfanView is designed to be a lightweight viewer/player which is noted for its speed, ease of use, and ability to handle a wide variety of graphic file formats. The software was first made available in 1996.
The program is named for after its creator, Irfan Skiljan of Bosnia and Herzegovina, living in Vienna, and is pronounced /ˈɪərfænvjuː/.[2] IrfanView works under all modern versions of Microsoft Windows (i.e. Windows 95 to Vista; Microsoft tested version 3.98, which was on the official Vista software list). It supports numerous file formats including: image formats such as BMP, GIF, JPEG, PNG (includes the optimizer PNGOUT), TIFF, non-image media files such as Flash, Ogg Vorbis, MPEG, MP3, MIDI, and text files.
After version 3.92, the installer could choose to also install an eBay toolbar in order to support the developer. In version 3.92, adding the toolbar was selected at installation by default, and the program was criticized by some as containing spyware. The option was not selected in version 3.97, and was replaced with an option to install Google Desktop Search from 3.98. However, a variant without installation required, i.e. a .zip file (containing the program and its default plugins) rather than an .exe setup package, is also available. IrfanView is "provided as freeware, but only for private, non-commercial use", and requires paid registration for commercial use.




48px non tire tread Non tire tread Tire tread version
The IrfanView logo and mascot is a flattened roadkill cat.[3] The 16px icon has tire tread marks across the caricature; the 32px icon is this "non tire tread" version; and the 48px icon has a gradient across the cat's body. The author of the software does stress, however, that he bears no ill will towards cats. In fact, the IrfanView website pictures him holding a cat.


The program is compact: the latest version is less than 1200 kB in size, although several megabytes of plugins are available to support numerous other file formats and features.
In addition to extensive viewing capabilities and file conversion options, IrfanView can also create screensavers and slide shows from collections of images with optional accompanying mp3 audio. These screensavers and slide shows can be created as “stand-alone” executables that will run on computers which do not have IrfanView installed.
A feature closely related to the slideshow and screensaver features is that of batch image translation. With slideshows, batch image translations and screensaver creation you can apply predetermined image processing steps.
Irfanview can be downloaded directly to a U3 compatible device.
IrfanView can also be used to create icons by converting common graphic files into .ico format. It also supports Adobe-compatible 8bf image processing filters, including many freely downloadable ones, though its ability to apply them to portions of an image is limited compared to full-scale image editors.
The program has built-in TWAIN support for retrieving images from scanners; it also has extended support for taking screenshots.
It can crop, resize, and rotate images. Images can be adjusted by modifying the brightness, contrast, tint, gamma level, and so forth, and by converting them between formats. Many of these changes can be applied to multiple images in one operation using batch processing.
IrfanView can direct the active image to open in an external graphics editor (Adobe Photoshop, for example) if the user has one installed.
In English by default, the program is internationalized in over twenty languages.


IrfanView has many plugins. Some include:
  • JPG_TRANSFORM, which allows some lossless transforms of JPEG images. For a free alternative, see jpegtran and the associate Jpegcrop.
  • IrfanPaint which adds painting features and tools with tooltips to IrfanView. The tools include: arrow, paintbrush, eraser, clone brush, color replacer, text tool, line, arrow-line, ellipse, rectangle, fill, color-picker, rotate, and measure.

IrfanView thumbnails

This function displays thumbnail file previews, allowing picture organizing and management. The program can be set to display the thumbnails at a wide range of sizes, from very small (50 × 50 pixels) to very large (600 × 600 pixels). The user can select single or multiple thumbnails, then perform the usual Copy/Move/Delete operations on them. Selected thumbnails can also be sent directly to IrfanView's Batch Processing module or opened with an external program such as Adobe Photoshop.

Copyright infringement and impersonators

IrfanView is freeware, although it is still copyrighted software; there is no other legitimate version other than that offered at Versions such as "IrfanView Platinum" or "IrfanView Pro" have appeared which may be copyright infringements that attempt to charge end users by using the name of a free product as well as potentially containing spyware or viruses.[4]

About the author

Irfan Skiljan graduated from the Vienna University of Technology. In a 2006 interview, 32-year-old Skiljan said that he was able to more or less live off the software, generating income with the sale of licenses for commercial users and of special versions for different customers.[5]
