Edges of Converted Images are Warbled

[Dale Dreher]

I really appreciat the lesson.  I will check those settings tonight when I Convert my next batch of pics and see how it goes.  Thank You!-Dale.dale@hazardtown.com On May 30, 2012, at 7:05 AM, Alfred J Treder wrote:   You DO want both dither and best interpolation, to correct aliasing. Dither is the term for rendering edges of features as NOT either/or for the choice of values for a pixel (at an edge), but somewhere in between the edge pixel value and the values of next-pixels away from the edge. It makes the edge pixels fade slightly into the background instead of their own little edges standing starkly against it. When you're short on pixels (and you ARE when you reduce resolution) you need every advantage to allow an analog (continuous) scene to look OK after digitizing it into discrete uniformly-sized pixels. You know, even with photographic film you are digitizing the continuous image from the lens into little silver grains in the emulsion, but they are usually so tiny you can't see them individually. Digital camera sensors have bigger grains (and are much more uniform) than photographic emulsion (with current technology). And then, to reduce the size of the digital file you are effectively making the grains much larger. You get some of the film effect of tiny grains next to larger grains by dithering and interpolating the uniform digital pixels. You would not want the dithering only if you have the edges in your image lined up with the edges of the pixels in your camera sensor, and want the sharpest possible presentation. Usually your image edges are a little off-angle relative to the rectangular arrangement of camera sensor pixels, and you will see a Moire pattern along those edges unless you soften the edges with dithering and interpolation. That's what you are calling wavy edges. Al“ When you come to the end of your rope, tie a knot and hang on.”-- Franklin D.

I don't know what that means, High Quality Interpolation.  I will look for it in Preferences, I guess, I and get back to you on how it works.I really thank you for trying to help.Peace.

Set your camera to a resolution closer to what you want for the finished product. Let the camera do the work of reducing the size. Look at scantips.com for info about resolution. A camera is just a fancy handheld scanner so most of what scantips has is applicable. "... scanning at the appropriate resolution for the job's purpose (instead of always using the maximum possible resolution) is the very best possible answer."

Could someone me with provide a very brief Applescript code snippet to show the proper usage of the "Count Color Pixels" Applescript dictionary element? I am trying to count the number of pixels in an image of a certain RBB color. Any working actual example would at least get me going. Thanks! Larry

property my_color : {65535, 65535, 65535} -- white set my_color to choose color default color my_color -- use the color picker tell application "GraphicConverter" tell window 1 count color pixels color my_color end tell end tell Operating on an image green.png of size 320 x 460 with pure green: tell application "AppleScript Editor" choose color default color {65535, 65535, 65535} --> {0, 65535, 0} end tell tell application "GraphicConverter" count color pixels window 1 color {0, 65535, 0} --> 147200 end tell Result: 147200 --- In gcmac@yahoogroups.com, Larry Knight <larryknight71@...> wrote: > > Could someone me with provide a very brief Applescript code snippet to show the proper usage of the "Count Color Pixels" Applescript dictionary element? > > I am trying to count the number of pixels in an image of a certain RBB color.
