Re: All kind of lossless image compression

As I looked the README, I think what you need is -ls option. Check line 138 . I'm not familiar with Visual Studio. In my Mac, I can build jpeg executable, however failed to build library, but I could do a simple check with the generated jpeg command. Example in README is slightly wrong. -ls option r...

Re: All kind of lossless image compression

I have not tried yet, but did you try it?

See Readme that mentioned about lossless.

convert.exe does not installed from Windows binary in 7.0.0.0.

As http://www.imagemagick.org/script/index.php says current release is 7.0.0.0, I tried to install it from Windows binary.
I tried Q16-HDRI-x64-dll and Q16-HDRI-x86-dll versions and both does not install convert.exe. Instead, it installs magick.exe.
Is it an intentional change?

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...
