The images I provided were meant to show an example of a group of colors from the source image and the final destination color. My source images are 15360x8640 and I wish for them to be downsized to 1920x1080. The reason I'm trying to use only certain pixels from the source image when resizing to th...

Do you want the color corresponding to the black squares or all of the white area? Assuming the black, then color=`convert 8x8.png \( checker85.png -negate \) \ -alpha off -compose copy_opacity -composite \ -scale 1x1! -alpha off -format "%[pixel:u.p{0,0}]" info:` convert -size 128x128 xc...

I'm trying to resize down not up, I enlarged the images so the pixels where easier to see.

What I have is an image that is 64 times larger than the image I wish to end up with. So for each 8x8 area. http://ompldr.org/vZGV4cw/8x8.png I wish to use a mask such as this. http://ompldr.org/vZGV4dA/checker85.png And use the masked pixels to generate a final color value such as this in the resiz...

Is there a way to do this currently in ImageMagick? What I was thinking is that I could use a checker pattern as a mask to only take into account certain pixels when resizing, but the -mask parameter doesn't seem to allow for resizing.

I had some help from a friend to write a Bash script which I execute through Cygwin.

Here is the resultant file. http://www.mediafire.com/?xcv0k805rnrjuqx

I'm trying to average every 10 frames into a single frame. The idea is to convert 240fps into 24fps to achieve good motion blur. I see in that thread you have a script but I'm not sure how to apply it to my own situation as I'm not familiar with Linux shell scripting. I have Cygwin so I should be ab...

I probably should have been more clear, I have over 1000 images to work with which I need to process in separate batches.

I have a sequence of TGA images recorded from a video game that I wish to convert to a lower frame rate by averaging adjacent images. I'm trying to do this to create temporally super-sampled motion blur. I only need to average 10 frames into 1 frame but I'm not sure how to go about writing a command...

I'm by no means a programmer, but I've been wondering how well true 2D radially symmetric resamplers like Jinc would benefit texture filtering for applications in 3D graphics such as video games. From what I understand, the fact that Jinc is radially symmetric is what eliminates aliasing over separa...

Is it necessary to compile ImageMagick from source in order to make use of -fft? I've never compiled a program before and I'm just wondering if there are builds of ImageMagick that come with it.

I'm on Windows 7, and my version is Version: ImageMagick 6.6.9-6 2011-04-14 Q8.
