convert.exe: geometry does not contain image `png.png'

[kwyjibo]

I'm trying to create a gif from small images that are stored on a single png, the "png.png" file size is 1024x1024.

Code: Select all

convert -crop 32x32+352+800 +repage -dispose 3 -delay 10 "png.png" -crop 32x32+384+800 +repage -dispose 3 -delay 10 "png.png" -page 0x0 -dispose 3 -delay 100 -size 32x32 xc:Transparent -crop 32x32+288+800 +repage -dispose 3 -delay 10 "png.png" -crop 32x32+320+800 +repage -dispose 3 -delay 10 "png.png" -loop 0 +dither -layers optimize "out.gif"

in a more readable form:
convert
-crop 32x32+352+800 +repage -dispose 3 -delay 10 "png.png"
-crop 32x32+384+800 +repage -dispose 3 -delay 10 "png.png"
-page 0x0 -dispose 3 -delay 100 -size 32x32 xc:Transparent
-crop 32x32+288+800 +repage -dispose 3 -delay 10 "png.png"
-crop 32x32+320+800 +repage -dispose 3 -delay 10 "png.png"
-loop 0 +dither -layers optimize "out.gif"


the error: convert.exe: geometry does not contain image `png.png' @ warning/transform.c/CropImage/574.

It generates a 1x1 pixels empty gif
The coordinates are correct I already checked them manually, I understand it has something to do with crop and repage but don't understand what after around 2 hours of testing and reading manuals and examples.

Hope someone can help me, thanks.

I am not sure why it does not work but I can see straight away that the image should come before the crop.

As Bonzo says, your syntax is incorrect. See http://www.imagemagick.org/Usage/basics/#why

For most image types (except vector formats), it should be

convert inputimage options outputimage

Thanks for the help, I read the page I'm not able to separate all the parameters into settings and commands by myself but I can check every command there and I believe I put them where they should be.

So I tried to simplify, moved the settings "delay" and "dispose" before the image, the operations "crop" and "repage" after the image.
Also tested without +repage and with -repage 0x0

convert -dispose 3 -delay 10 "png.png" -crop 32x32+352+800 +repage -dispose 3 -delay 10 "png.png" -crop 32x32+384+800 +repage "output.gif"
convert.exe: geometry does not contain image `png.png' @ warning/transform.c/CropImage/574.

more readable command line:

Code: Select all

convert
-dispose 3 -delay 10 "png.png" -crop 32x32+352+800 +repage
-dispose 3 -delay 10 "png.png" -crop 32x32+384+800 +repage
"output.gif"

Anyone testing/trying to do what I want to do would be nice.

My version, just in case:

I am not sure what you are trying to do? But try

convert \
\( -dispose 3 -delay 10 "png.png" -crop 32x32+352+800 +repage \) \
\( -dispose 3 -delay 10 "png.png" -crop 32x32+384+800 +repage \) \
-loop 0 "output.gif"

or for windows

convert ^
( -dispose 3 -delay 10 "png.png" -crop 32x32+352+800 +repage ) ^
( -dispose 3 -delay 10 "png.png" -crop 32x32+384+800 +repage ) ^
-loop 0 "output.gif"

However, -delay 10 may be too fast for many animation viewers to use so it may animate slower than that.

So lame that I didn't know the parenthesis trick, I think that was the only thing wrong, the parameter order was being kinda tolerated.

Thanks a lot.

If that works, try this. It will save reading the image twice.

convert "png.png" ^
( -dispose 3 -delay 10 -clone 0 -crop 32x32+352+800 +repage ) ^
( -dispose 3 -delay 10 -clone 0 -crop 32x32+384+800 +repage ) ^
-delete 0 -loop 0 "output.gif"

For that simple example delay is set to 0 according to gimp, for more complex ones like the real animations I'm creating with the script I get rubbish and the gif goes png.png size.

I guess the batch will just read files several times, hope windows cache helps, anyway I will only process in batch now and then so is not a big issue to read images more than once.

Thanks again for all the help.

Most viewers will not take a zero delay animation. If they accept it they will put some minimum value in anyway.
