adding the "--with-freetype=no" to the configure line does not fix the problem. The same error occurs.

ok so i did this sudo apt-get install freetype* and it seemed to install stuff. I repeated the attempt to compile ImageMagick and got the same errors. I thought perhaps the free type install went bad so I tried it again to make sure I did not overlook any errors. This time 'sudo apt-get install ...

I followed these instructions to build ImageMagick sudo apt-get install build-essential checkinstall && apt-get build-dep imagemagick -y wget http://www.imagemagick.org/download/ImageMagick-6.9.1-2.tar.gz tar xzvf ImageMagick-6.9.1-2.tar.gz cd ImageMagick-6.9.1-2/ ./configure --prefix=/opt ...

tnx. i knew it probably wasnt an imagemagick command but want sure.

that explains why the histograms change the way they do.
when i delete the background so it is transparent leaving only a black numeral, poly now generates a completely black background. Obviously, poly is finding no value for the background and assigns it a value of 0 (=black)

tnx muchly, fmw42.

using the 64 bit version of IM with the dll. Here are some commands I tried and the errors I got >display rose: display.exe: delegate library support not built-in `' (X11) @ error/display.c/DisplayImageCommand/1899. >xdpyinfo | grep dimensions: 'xdpyinfo' is not recognized as an internal or external ...

tnx fmw42 aha, I think the issue is that i am starting with b&w images. since the exponent is applied first, this has no effect on the resulting appearrance. after all, black to any exponent is still black. However, that said, the histograms of the two results using this code: convert [1-3].jpg ...

using this line convert %d.jpg[1-5] -poly ".1,1 .2,1 .3,1 .2,1 .1,1" out.jpg gives a nice sequence of images with progressively increasing and decreasing darkeness. However, the background is taking on a creme color. even using -background none doesnt avoid this. although -auto-level after the poly ...

trying to learn how to use this command but i am failing miserably. this command convert [1-3].jpg -poly '1,1 1,1 1,1' out.jpg gives this output C:\Users\Stefan\Desktop\test>convert [1-3].jpg -poly '1,1 1,1 1,1' out.jpg convert.exe: invalid argument for option `-poly': '1,1 @ error/convert.c ...

And this works too - without the clone command set /a U=0 set /a V=1 set /a W=2 set /a terminator=7 :loop set /a W= %W% + 1 set /a V= %V% + 1 set /a U= %U% + 1 if %W%==%terminator% goto close goto open :close echo %W% pause exit :open echo %U% %V% %W% convert %%d.jpg[%U%-%W%] -average %U%out.jpg ...

FINALLY!!! got this to work set /a U=0 set /a V=1 set /a W=2 set /a terminator=7 :loop set /a W= %W% + 1 set /a V= %V% + 1 set /a U= %U% + 1 if %W%==%terminator% goto close goto open :close echo %W% pause exit :open echo %U% %V% %W% convert %%d.jpg[%U%-%W%] ^ ( -clone 0-2 -average -write %U%out.jpg ...

tnx snibgo but your command also did not work. it's the same issue i ran into. the variables v and w are not being evaluated. here is what I saw: C:\Users\Stefan\Desktop\test\minitest>bconvert.bat C:\Users\Stefan\Desktop\test\minitest>for %U in (*.jpg) do ( set /A V=%~nU+1 set /A W=%~nU+2 convert ...

I said within the FOR brackets , not outside them. I am tired and dont know what you mean-there are no brackets for me to put the set statements into. I tried these and they all FAILED for %%U in (*.jpg ) do ( set /A V=%%~nU+1 set /A W=%%~nU+2 convert [%%~nU,%V%,%W%].jpg -average %%~nUoutput.jpg ...

Anthony, I also tried this for %%U in (*.jpg) do convert %%U ( -clone 0-2 -average -write %%Uoutput.jpg +delete ) -delete 0 null: and got this C:\Users\Stefan\Desktop\test\minitest>for %U in (*.jpg) do convert %U ( -clone 0-2 -average -write %Uoutput.jpg +delete ) -delete 0 C:\Users\Stefan\Desktop ...
