It would in ImageMagick 7.

Is there a good reason to make the order of options matter?

I'd rather the future versions keep the status quo as far as the order of options is concerned.

Just tried the code you provided (with -alpha off) and it works. If I add the option "-geometry x1000", the gap reappears, though. However, if I apply the option "-alpha off" in the first step to convert the EPS files to PNGs, then I can use the -geometry option without problems. Here are my codes ...

Let me try: im01.eps https://1drv.ms/u/s!Au5wxS03IZVjbpvM9uQVkyp4Jys im02.eps https://1drv.ms/u/s!Au5wxS03IZVjb5iJyNtvQ0EqBpY The above are the URLs of the two images in EPS format. Hopefully, they work. The commands I use to convert them to PNGs: % convert -density 150 im01.eps im01.png % convert ...

I have not located a photo service website that would not automatically change all uploaded photos to JPEGs. Meanwhile, I experimented more with JPEGs and PNGs, and found that this is a more complicated issue. 1.) I save my plots into EPS files and convert (ImageMagick command) them to JPEGs, and ...

I am on a macOS High Sierra Version 10.13.4 and just upgraded my ImageMagick to 6.9.9-40 Q16 x86_64 and libpng 1.6.35 . I have just repeated everything I presented in earlier posts, and got exactly the same results: There are gaps between different images in combined PNG images, but not in combined ...

Just checked mine by using "convert -list format" and found the following:

PNG* PNG rw- Portable Network Graphics (libpng 1.6.18,1.6.21)

A colleague of mine has libpng 1.6.29 and has the same problem as I do with PNG images.

I will look to upgrade my ImageMagick.

Many thanks.

I tried both the following: % convert +append im01.png im02.png final_im.png % convert im01.png im02.png +append final_im.png and got the same resulting image (with borderlines and gaps). And this problem arises only when I work with PNG formatted files, not with JPEG files. The problem with ...

I have not used "montage" before---until now. After experimenting a little bit with "montage", I found that if I use "montage -geometry +0+0" instead of "convert +append" to combine two PNG images into one, those borderlines and the gap between the two images in the resulting PNG image are gone. Now ...

A colleague, who uses a Mac and ImageMagick Version 6.9.8 ..., tried the same thing on his machine with the two EPS files I sent him. The result is the same: There is a gap, or dark line, between the two images in the combined one.

Thank you for your suggestion! I'll manage to upgrade it and let you know the result later.

I'm also posting the combined JPG image here. This is what I like: The images do not have borderlines, nor gap (or line) between them. https://cn4moq.bn.files.1drv.com/y4mHWt5_KvwwDAR48T9yU49BpUSGbvgYwL9R_nQaWaGRrsmFK0ddMdWvlH_VpmH-krOG-O3p3OaDG9DJGliVMnd3buFZ_DCwl2OtMfYc8IX0ZuQlYDJtEIsW ...

The images are as follows. As you can see, in the combined image there is a black line (the gap I am talking about) between the two images, and each image also has a borderline, and I suppose the gap is just the borderlines. im01.png https://cn7wtw.bn.files.1drv.com/y4mn7WlYuNkDx5 ...

Thank you for your reply! I tried all your three suggestions, and the resultant image remains the same. I'd like to let you know that I can see the dark gaps (as solid lines) between the two images in final_im.png when I view it in Preview , and the gaps show up as dashed lines in GraphicConverter ...

Thanks for reminding. I just added the version number of my ImageMagick and the exact command in the edited original post.

Hi, everyone: I use a macOS High Sierra Version 10.13.4 and my ImageMagick is Version 6.9.0-0 Q16x86_64 2015-07-30. I use the command "convert +append" and "convert -append" to combine two PNG images into one, and the exact command in an X-window is like %convert +append im01.png im02.png final_im ...
