Web Image Guru was designed to meet demands of the Game artists , which create rich graphics games for consoles like Game Boy Advance, Sony Play Station 2, or mobile devices. The key features of Web Image Guru which are interested for Game Artists are:
- High quality color reduction
There several comparisons of Vimas color reduction algorithm with competitors from most popular graphics optimizers - Adobe Photoshop (Image Ready) and Macromedia Fireworks. Here you can compare it with the results of the OPTPiX iMageStudio - one of most popular program for color reduction in the game development. This comparison is based on the results, provided by iMageStudio developers on their web site.
Images below show the comparison of color reduction to 16 colors in iMageStudio and Web Image Guru.
Images created with Web Image Guru have bright, saturated looks even with such extreme color reduction.

PNG-8 alpha transparency (palette alpha)
-
Web Image Guru supports index color (or palette) images containing alpha values (and, of course, true color images with alpha channel via PNG-24 mode also). This feature available only for PNG-8 images and has name Palette Alpha or in some other programs Alpha Transparency. It is very useful if you need to make some image composition. Web Image Guru 5.0 allows manual editing of color and alpha values in palette. It also supports external palettes with alpha values in Microsoft pal format to use one palette for several images.Here you can compare images with palette alpha generated by Web Image Guru and Macromedia Fireworks MX 2004 (we do not have OPTPiX iMageStudio and there are no such samples on their web site ). Original image may be downloaded from here. PNG-8 with palette alpha does not supported by Microsoft Internet Explorer, therefore actually you see screen shots from Image Guider, but all images linked to actual PNG-8 files, which may be downloaded by right-mouse click or opened in Mozilla family browsers.

Automated mipmap generation
Generation of mipmap image never was so simple and fast. Web Image Guru contains 2 presets for mipmap generation for PNG-8 and JPEG image file formats. If mipmap sequence generated for images with palette, it is possible to use for all images the same palette, generate for the first image in sequence. It is possible to save all generated images in different folders or select name extension (expansion) for any of them. Due to powerful batch processing any numbers of image files may be used in this workflow. Web Image Guru may be used via Adobe Photoshop actions technology at the last step of some special image processing algorithm.
