But particularly when it comes to web design, one would like full support for gamma correction and for PNG's various transparency capabilities, preferably with an option for best (or at least good) compression. Not every feature is vital, of course, and some users may want only a subset of these.

Ability to preserve and store user-defined text information.

Options for both fast saves and best (slowest) compression.

Reasonable default compression settings: adaptive filtering turned on for all image types except palette-based “medium” zlib compression level (say, between 3 and 7) unused palette entries omitted if simple/cheap transparency, palette ordered so that opaque transparency entries can be omitted.

Ability to read, modify, and write 16-bit grayscale or 48-bit RGB images without conversion to lower bit depth.Color correction: either chromaticity, sRGB, or full ICC profiles.Gamma correction, including calibration of display system.Option to quantize and dither full RGBA images down to RGBA-palette images.“Cheap” RGBA-palette transparency (i.e., where each palette entry has red, green, blue, and alpha components).Full alpha transparency (also known as alpha channel or alpha mask).Simple transparency with any basic image type (i.e., single color marked as fully transparent).Option to quantize and dither images with many colors down to 256 or fewer.

Images with fewer than 256 colors automatically saved as palette-based (or grayscale, if appropriate).Basic image types: RGB, grayscale, and palette-based.Here is a list of the support one would like to see in the ideal image editor: But there are many levels of understanding, and only a handful of editors exercise PNG's most interesting features. To create a PNG image from scratch, one needs an image editor that understands PNGs.
