Re: Incorrect use of user-defined channels converting PSD files

We have read the photoshop file format specifications (http://www.adobe.com/devnet-apps/photoshop/fileformatashtml/) and the specifications don't mention how we should interpret the extra channel. We have various test files where that extra channel is the alpha channel. This is the first file where...

Re: Creating multipage Tiff from file list

Can I avoid decompressing stage?
No, not that I know. ImageMagick will decompress and then recompress the output if desired by the -compress option.

Re: Creating multipage Tiff from file list

I am not sure, but they probably get enlarged when converting to ImageMagick internal format. Also your tiff files may be compressed and during the conversion, ImageMagick must decompress them.

Re: Creating multipage Tiff from file list

ImageMagick will read all the files into memory as those temp files. So if you do not have enough temp space, that could be an issue. But ImageMagick will use disk if not enough RAM. But that would account for your large use of temp space if you have many images to make into a tiff. Whether you use ...

Re: Creating multipage Tiff from file list

Those files should be deleted automatically. If they do not, then there is something wrong. You can delete them. See if they get left behind again. But what was your exact command line? If you do not reference your files correctly, perhaps bogus files will be created and left in your TEMP folder. Be...

Re: Images become blurry on downscale since I updated to v7

Cubic is a broad range of filters defined by constants b,c. See http://www.imagemagick.org/Usage/filter/#cubics. I believe b is the blurring constant. So using b=0.5 may be adding too much blur. What is called (Keys) cubic convolution (the old standard) is what ImageMagick calls filter=catrom. It pr...

Re: Creating multipage Tiff from file list

As I mentioned above:

An alternate method is to simply put all your images in a new directory, if they are not already. Then change directories to that directory. Then

Code: Select all

convert *.tiff newimage.tiff
Use magick rather than convert if you are on IM 7.

Re: trim & make transparent (region)

On IM 7, there are changes. That is why it is always a good idea to identify your IM version and platform. Try

Code: Select all

magick input.png -fuzz 10% -fill none -draw "alpha 10,10 floodfill" result.png
See some changes in http://imagemagick.org/script/porting.php#cli

Re: trim & make transparent (region)

You can do this to change the pink to transparent. convert input.png -fuzz 10% -fill none -draw "matte 10,10 floodfill" result1.png There are some red lines left. So for that you would likely need to shave or chop off those parts of the image. See http://www.imagemagick.org/Usage/draw/#matte http://...
