It most certainly is. I can see it as plain as day. You are looking at something else.

Pissant, you may be able to see it plain as day, but I KNOW what it is. It is an "E".

Don't you think that since I made the picture—and can Do IT AGAIN if you want—that I should be in a better position to tell YOU what it is? I can do a screen magnification on the original PNG image and see it first as an "E" and then see it morph into a "K" as you the magnification routines alter the data. When you remove better than 70% of the data that describes an image in its RAW form to make it a more "downloadable" size, something gets lost. In this instance pixel color data used to anti-alias the letters was simplified... and in some cases averaged data from FOUR different color pixels into having all four pixels use the average. That means that information is LOST. An "E" and a "K" are very similar... especially when you take the dithered anti-aliased areas on the edges of the black and make them a lot simpler.

Here is a comparison. On the LEFT is the JPEG conversion of the PNG on the RIGHT. Both are magnified 700% in Photoshop on the Mac.

Note that the JPEG version of the EXACT SAME FILE does indeed look like a "K" while the blown up PNG still retains an "E" shape, with the complete base line and a more complete cap line of the E while the JPEGed file has lost more of the color data in both the base and cap lines, making those lines lighter, adding to creating the illusion of a K. Note also the greater clarity of the lines above and below the letters on the PNG image. Note also the general fewer differentiated pixels in the background paper colors on the JPEG side as opposed to the more variable color of the PNG image's pixels. Look also how JPEG averaged the pixel colors of the "L" of Lavender compared to the much sharper "L" on the PNG.

The human mind wants to resolve un-resolvable data into something it can interpret. It is an amazing capability to make a gestalt of data to create a recognizable shape. Consider the following image. Look at it close up, and then look at it from a distance and notice what you perceive, not what you actually see! It may help you understand why you see a "K" when it actually is an "E"
