Re: convert image 75 dpi to 300 dpi

Just an FYI (and possibly a BUG), none of this dpi stuff works with EXR images. Yes, openEXR assures me that it supports dpi. Have any of you tried changing the dpi of an EXR image? If you've successfully done it. I would love to see that convert call. Thanks. - Jimbo You can request an enhancement...

Re: How to read the dpi resolution of an image

Do you have OpenEXR installed such that imagemagick can find it and report it in

Code: Select all

convert -version

Re: How to read the dpi resolution of an image

All your command are wrong as I mentioned above. Changing the density before reading a raster image works for vector formats. You should specify a density after reading the input raster. Try convert input.exr -units PixelsPerInch -density 180 output.exr If that does not work, then ImageMagick has no...

Re: Change DPI while keeping resolution

Using density before reading the image is only for vector formats such as PDF, EPS, PS, etc. It makes no sense or affect on raster images. Apply the density after reading a raster image such as EXR. But you may need special defines for EXR output. See EXR format information at https://imagemagick.or...

Re: rize and add radial-gradient background

You should not use a size with height = 0 (-size 500x0). That is not good. Is that a typo mistake? What is your ImageMagick version and platform? Please always provide that as syntax may vary. I assume from your command, though not properly printed, is Windows. I do not understand the question? Plea...

Re: new to convert - have error message

If you are sure the file is in the directory from which you specified your command, then you likely do not have Ghostscript installed as a delegate. ImageMagick uses it to convert PDF files to other formats. Check if you have Ghostscript installed. See if gswin32c.exe can be found on your system. Al...

Try simply downloading the https webp file and save to webp. Then do identify on that. You can even pipe it

Code: Select all

Re: identify returns different results for HTTPS than for local source

Mostly identify will show tiff if you do not preface the file with DNG:. See https://imagemagick.org/script/formats.php DNG R Digital Negative Requires an explicit image format otherwise the image is interpreted as a TIFF image (e.g. dng:image.dng). But I am not sure you can do that with http:// or ...

Re: Scaling various images to A4 size including borders

Post an input image so we can test with your command and then correct it.

Try replacing -page "A4<" with -resize WxH for the WxH corresponding to A4.

Re: .png to .pdf conversion is failing with memory allocation error.

-resize needs a new size value. You cannot just use ! by itself. See https://imagemagick.org/script/command- ... p#geometry
