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 ...

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....

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: conv...

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 DP...

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&quo...

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. The image can be found here: http://www.fernando.dk/tgd...
