Very helpful. Thanks!

The to-RGB conversion is important as the preview image won't display correctly in most browsers otherwise.

Final what works for me is this:
[srcfile] -strip -flatten -colorspace sRGB -resize 250x250 -quality 90 [out]

Thanks again,

Yes that indeed works! Follow up: My full conversion args include forcing of RGB output, and that does not seem to go well. My conversion args are currently: convert.exe -alpha off -strip -colorspace sRGB -resize 1024x1024 -quality 90 xc:white "GALAXY S III 4G.png" t.jpg Even though it is not ...

Hi all. ImageMagick version: ImageMagick 6.8.9-6 Q16 x64 2014-07-22 Windows 7 64bit. Converting parameters used: convert "GALAXY S III 4G.png" t.jpg I don't know where the PNG originates from (yet), but all other major viewers (Photoshop/IExplore/Firefox/Picasa) can view the file properly. File is ...

snibgo wrote:"-alpha off" works for me, eg:

Code: Select all

convert SEP_12_SBE_box_shot.tif -alpha off -resize 100x100 -strip x.jpg

Ah, I think it's a combination of -alpha off and -resize, opposed to -geometry

because, -geometry and -alpha off still produces the incorrect.

Many thanks!

Hi all I've run into an issue with convert.exe on Windows. We have been using Imagemagick for a couple of years without encountering this issue. It's this image: http://www.fernando.dk/SEP_12_SBE_box_shot.tif , which has a 2 channels and 3 paths embedded. I normally create thumbnails like this ...

Is it possible that it contains an imbedded thumbnail and on or the other of the image and thumbnail are at 44dpi and 300dpi respectively? Seems likely, and I have addressed your question to the image originator and will revert back. The image is used in our DAM and the image was rejected by the ...

We've run a number of open source packages against the image and they all report 44DPI. I'm not sure how to interpret this statement. The following two lines of .NET code (which I provide with no restrictions, or limitations) ;-) : Image newImage = Image.FromFile(@"c:\temp\tgdpi44Issue.jpg ...

Oh dear, forgot to mention something about versions (forgive me)

Hi all I'm experiencing several images where ImageMagick identify reports incorrect DPI. For this particular incident, ImageMagick reports 44 DPI with command: "identify -format %x [file]" Windows explorer and Photoshop report 300dpi.
