Re: Merge three images at different positions on a transparent canvas

I couldn't get the canvas to be transparent. It always turns out black. You will need -background none. And output file should be placed last of the command sequence. convert xc:none[200x200\!] -background none \( rose: -resize 50x50\! -geometry +25+125 \) -compose over -composite \( rose: -resize ...

Re: Opening a PDF File - All that is visible is transparent checker board

Well, success. Apparently, latest, greatest of IM doesn't work that well with gs 9.16. I have downgraded my gs to 9.10 (what you have) and it works now. FYI, it seems to work with gs 9.15.

Re: how can convert a multilayer psd file to single layer psd file?

First, I have to say it is impossible to create exactly the same file between from Photoshop and from ImageMagick. Recent Photoshop (after CC) seems to have a feature to run like a service and client can operate for some command from JavaScript. But even if your conversion can be achieved, md5sum wo...

Re: how can convert a multilayer psd file to single layer psd file?

I don't understand why layers other than 0 remains, but I can say about the size now. PSD spec allows Raw Image Data (0) in image data section, and IM create that one, whereas Photoshop create compressed one. (Someone can check that after you post the image.) And you stated DerClose.psd is created w...

Re: Batch watermarking using -tile

So -tile would work in almost any place in composite No! Order is important. The -tile should come right after composite and any multiple input images must be in the correct order for any compose setting. My point is -tile takes no file argument in composite. So old IM allowed allowed some wrong or...

Re: Batch watermarking using -tile

Ah, yes, true, thanks. So "-tile" can be an operator in "composite". In man pages in composite, -tile is defined as image settings with no arguments. So -tile would work in almost any place in composite, (although some are not recommended order and currently seems to work for backward compatibility...

Re: Avoid a color in a jpg

Then perhaps another program can convert that without loss to JPEG. I had thought so, and the other program would be mozjpeg. But it seems that's not true. What it guarantees is jpg to jpg conversion is lossless. As far as I tried (a little), cjpeg comes from jpeg9a can create lossless jpg from bmp...

Re: Issue of montage command

I see no problem on your all 4 image sets when converting with ImageMagick 6.9.2-0 Q16 x86_64 on MacOS (installed from MacPort.) I guess your jpeg-turbo may the cause of problem. In my environment, official jpeg is also installed from MacPort and its version is 9a.

Hmm, but 'man mogrify' (or 'man convert') shows "-tile filename" is described as an image operator. Do you think it's a manual bug?

Thank you snibgo for correcting. (Currently it works even at the very first position, probably for backward compatibility.)

Re: How to push text label down

You can use -geometry +0+0 on its own to set the distance from the top left corner or use it with -gravity to adjust it from there. Although it may not work with label: depending the effect yoU are after can you use -annotate ? -extent seems to work for label; you have to use negative y value to mo...

Re: Converting PDF to JPEG is giving negative output

It seems -alpha remove will generate white background. (As internal png generated by pngalpha has white background.) Cite from http://ghostscript.com/doc/current/Devices.htm The pngalpha device responds to the following option: -dBackgroundColor=16#RRGGBB (RGB color, default white = 16#ffffff)
