Re: MagickWand C API equivalent to below command.

If you output the command line result to a PNG, it has a transparent background. Even so, it seems to be a very complicated command which seems to just invert the black and white in cnbc_i.jpg, make the black transparent and replace the white area with the pattern in cnbc_p.jpg. Is it supposed to d...

Re: append images vertically using MagickWand C API.

The source code for MagickAppendImages() is in magick-image.c. The comments tell you how to "stack them top-to-bottom". Thanks a lot snibgo, I haven't noticed the second parameter of that function. MagickAppendImages(wandG,MagickTrue); With this it's working now. I just need to change second argume...

I have multiple images and I need to append them and convert it to one image. For that I wrote below C program, it works fine except it appends images horizontally. How can I append images one after another? For example using convert +append appends images horizontally and convert -append append ver...

Re: Anyone please explain me below command.

Above, I said that when a composite has three inputs images, the third is a mask. I had forgotten that this is not true for displace or distort composites. For these, the second image is the x-displacement, and the third image is the y-displacement. So there are two (grayscale) distortion maps, not...

Anyone please explain me below command.

Code: Select all

 convert ./one.mpc ./two.mpc ./three.mpc -channel rgba -alpha on -virtual-pixel background -background none -define compose:args=6000x254.91 -compose displace -composite ./one.mpc
What I understood is it takes three images and apply all the effects on all three images and finally merge into one.

As Bonzo says, you need to calculate the x and y offsets.

To centralise the composite, the x-offset is the difference in the image widths, divided by two. Likewise for the y-offset.
Yes, I did that as an alternate option, as gravity creates a problem. Thank you!

A bit of a pain but could you write some code to calculate the co ordinates for the crop?
