1. Hicolor Pixel Blending
7 May 2001 (2 posts) Archive Link: "hi color pixel blending"
People: Deepak T, , Sven Neumann
Deepak T writes " I am writing a 2D 16 bit color arcade game. I have certain sprites (explosions, glows) which are drawn against a black background, when I draw these against a different background the sprite's edges do not blend with the background and the sprite looks bad, I am not talking about anti-aliasing here, I am talking about reading rgb of source pixel and combining it with rgb of destination pixel to make it look natural (the way it has been drawn against black background). ... But due to lack of vision, all the graphics have been drawn already against black and saved in bitmap format, so I do not have a alpha channel and I have only one layer in the images. Now I cant seem to blend them right with the backgrounds." Sven Neumann suggested using a real alpha channel (using ColorToAlpha would convert the black background to an alpha channel) or color-keying, where the color black stands for "No Color" in the image. Sven also suggests checking out the DirectFB APIs for the Linux frambuffer at www.firectfb.org (http://www.direftfb.org)
2. Ermapper / ECW Support
8 May 2001 - 9 May 2001 (4 posts) Archive Link: "Ermapper / ECW Support"
People: Steinar H. Gunderson, Roel Schroeven, , Guillermo S. Romero
Tyler Mitchell asked if anyone had added ECW support to the Gimp. The SDK is located at http://www.ermapper.com/download Steinar H. Gunderson wondered how the claim " More people use the ECW technology to compress imagery than any other product" could be correct. Guillermo S. Romero was wary of the patent claims listed on the site. Guillermo thought would be best to avoid more LZW madness and added the company could always supply a plugin themselves. Roel Schroeven agreed that avoiding another LZW fiasco was in everybody's best interest. Roel also pointed out that 'ER Mapper' was aimed at very large bitmaps and orthorectification.
(ed. [Cris Flagg] Patent 6,201,897 for "Transformation and selective inverse transformation of large digital images" (http://www.delphion.com/details?&pn=US06201897__) was issued to Earth Resource Mapping of San Diego, CA on March 13, 2001 )

This is gimp-print version 4.1.7, a development release on the 4.1 line.
This software includes the Print plug-in for the Gimp, and GhostScript and CUPS drivers.
