I've tried a pre-rendered board image (loaded from a PNG file), but that's even slower than just drawing the rectangles. Since you presumably have only a binary or just a few colors in your board, why not use a precomputed board stored as a gif with just a few colors in its palette. That would have...

did you see viewtopic.php?f=18&t=15708 just two topics down the list? apparently it is not yet implemented in Imagick, but they are working on it.

Two reasons my technique above with -convolve does not work is 1) your lines are not perfectly vertical and MORE IMPORTANT 2) your lines are thicker than 1 pixel wide, which was the assumption of the convolution kernel provided above for my example. Unfortunately, I am not sure what you can do to re...

I pointed this topic to Wolgang Hugemann, who wrote the Usage Under Windows page. He asked me to post the following as he is out of town. Take a look at his Usage Under Windows page regarding "enabling delayed expansion" As I am not a Windows user, I don't understand much of this, but I th...

If your images have only about 10 TRULY unique colors (and not just visually appearing that way), then you could try simply reducing the size of your input images, say by 10 using a non-interpolating reduction such as -sample and then get the unique colors. convert image.tif -sample 10% -unique-colo...

-convolve was broken for a few releases between about 6.5.9.5 and 6.6.0.3. I believe it was fixed in 6.6.0.4 and definitely by 6.6.0.5

Perhaps that is a lightroom issue. You don't need lightroom to run mogrify. You can open a terminal window or DOS window and run it in command line mode to process every image in some folder. It is not limited to 9 images. See syntax at http://www.imagemagick.org/Usage/basics/#mogrify I understand y...

Is "mpr" a pseudo-format that keeps the image data in memory? I've been looking for something like that but couldn't find it in the documentation. I've tried a pre-rendered board image (loaded from a PNG file), but that's even slower than just drawing the rectangles. I can't use your meth...

nothing explicitly exists today to my knowledge. however Anthony is still working on his morphology functionality and perhaps he might look into adding the convex hull if practical.

draw the board by tiling a 2x2 pattern.

convert \( -size 15x15 xc:black xc:white -append \) \( +clone -flip \) +append \
-write mpr:checks +delete -size 240x240 tile:mpr:checks board.png


You can play with the colors and size of the squares and the size of the result to achieve your board design.

Don't know Imagick, but in command line, see the following functions:

-cdl --- http://www.imagemagick.org/script/comma ... ns.php#cdl

-function polynomial --- http://www.imagemagick.org/script/comma ... p#function

GoToMeeting is a service I and others use to bring you in remotely to view my screen with me.
It is really simple.
We can use reqular telephone for audio.

Sorry, I don't have GoToMeeting.

I do not have Skype.

I am on the West Coast in Sunnyvale, CA

A 10 AM PDT would be better for me via conference telephone or just by email.

see http://www.imagemagick.org/Usage/windows/#calc_set

perhaps that will give you some clues how to do it

Sorry, I am using a Mac. Don't know much about Windows/DOS
