Re: Noticed an inconsistency with Pseudo-filename '-' across different versions of ImageMagick

Have you tried 7.0.7.21? Perhaps it is a Windows Imagemagick issue or a Q8 issue? I was using Q16.

Re: Having black text on white background plus rest colors

Please always provide your IM version and platform. Also post an example image to some free hosting service that won't change your image format (such as dropbox.com) and put the URL here, so that we can see exactly what you are trying to do.

Re: Noticed an inconsistency with Pseudo-filename '-' across different versions of ImageMagick

Proper IM syntax is to red the input first. IM 6 is forgiving, but IM 7 is not. Try "C:\Program Files (x86)\ImageMagick-7.0.7-Q8\magick.exe" "test.png" -depth 8 -type TrueColorMatte TIFF:- | "C:\Program Files (x86)\ImageMagick-6.8.8-Q8\identify.exe" -verbose - This works fine for me in IM 7.0.7.21 Q...

Re: Saving a BMP file with 16 bit pixel resolution (5:6:5)

I had noted above that it was supported for BMP (BMP4), but not for BMP3. See also documentation for that at https://www.imagemagick.org/script/comm ... php#define

Re: PAID: PDF color profil settings

As snibgo has said, you would be better extracting the image from the PDF and resizing to the pixel size you want and assign the density you want for printing as well as the color profile. Then not putting that result back into a PDF shell. This would be something like: pdfimages -png image.pdf new ...

Re: Not using all available resources

22500*22500 = 506250000 or about 506 Mpixels (time 6 for 3 channels at 16-bits per channel = 15 GB) just for the input rasterized SVG file (not counting the 1200x1200 pixel output image, nor for any intermediate image that may be needed). But that should be enough if you have 64 GB RAM and can use i...

Re: Not using all available resources

Looks like you have RSVG as a delegate. Do you have Inkscape on your system. Perhaps RSVG is limiting it. Inkscape is probably a better renderer. What is your version of RSVG? Is it up to date?

When you add -verbose to your command, what does it say about the Renderer?

Re: PAID: PDF color profil settings

Our print company gave us 3 options in descending order of preference: 1) To embed an sRGB ICC profile in the image That seems the best option. Extract the image with pdfimages, assign an sRGB profile, and send that to the print company. I did that with this file and you can see that the extracted ...

Off topic: I see you have made use of -print now fmw42 8)
I had to, since -format would have to be used twice, once for the file format and the other for the filename. So I just tried using -print rather than -format "%f" -write info:. To my surprise, -print worked in mogrify.

Re: PAID: PDF color profil settings

I did that. I used pdfimages to convert to tiff and also to png. It showed sRGB. There was only one large image, but pdfimages made two images. The second was completely blank. IM sees only one page as do other PDF viewers.

Re: looking for docs for PRINT command

I do not think Imagemagick has a direct print to printer command for images.

Re: Not using all available resources

The policy.xml file can be in several places. You must edit the main one. See https://www.imagemagick.org/script/resources.php. I do not know the Windows file system to tell you where that is. The other locations can only make the limitation smaller.

Re: PAID: PDF color profil settings

Darren, I am a bit confused. You first post says you want to convert to sRGB. But your second post seems to imply you want cmyk. Your PDF already is sRGB with a fully opaque alpha channel. Imagemagick sees no profile associated with the PDF. EXIFTOOL shows EmbeddedImageColorSpace: DeviceRGB, which i...

Re: Rending high dpi svg then downsampling - sensible?

try

Code: Select all

convert -density 1800 image.svg -resize WxH image.png
where WxH is your desired PNG dimensions. This is a typical process for converting SVG to raster format. The density must come before reading the svg.
