Re: convert: NoImagesDefined

For Imagemagick 7, use magick not convert. Convert calls IM 6 and if you have not installed the legacy components on Windows, then IM 6 convert will be missing. What do you get from magick -version Does it list png? If not, then you have not installed the PNG delegate library or did not install from...

fmw42: almost, it’s 96, not 72. Also requires -background none. I tried up to a factor 8 to no avail.
Correct, my mistake. 72 is for PDF, etc. But for SVG it also depends upon which renderer you are using and what version. See https://imagemagick.org/discourse-serve ... =4&t=35112

Re: Jaggy results with using maps for perspective transform

More properly, to get the same size output, use a density factor times 72 and then resize by the inverse factor. For example 4*72 and 1/4=25%

Code: Select all

convert -density 288 map_src.svg -resize 25% map_src.png

Also provide your exact command line. Perhaps your syntax is in error. What is your platform?

Perhaps you should share your thoughts/suggestions here first before editing the documentation.

Re: Any recom for HDR (6x2EV) and batch proc?

I do not understand. Your second image does have max values for each channel of 65535. I do not see any values in the e+08 range. Where do you see that?

Re: Jaggy results with using maps for perspective transform

Why go to all the trouble of a map solution when you can do perspective directly with -distort and high quality sampling?

See my various Imagemagick scripts including cylinderize and tshirt at my link below if you want a Unix-based solution that can run from PHP exec().

Re: Any recom for HDR (6x2EV) and batch proc?

Profiles can be anywhere. Put them where desired. Then use the full absolute path to them or a relative path when you want to use them.

Re: Store results of "convert" to variable in windows batch script

If on Imagemagick 7, use magick, not magick convert. It will invoke IM 6 behavior. Other IM 6 tools such as identify, do need to be prefaced by magick when using them in IM 7.

Re: perceptualHash() not documented in API

The perceptual hash used does not conform to hamming distance. It uses a sum squared difference metric since all the 42 values are floats. This perceptual hash metric is pretty much settled other than any potential bug issues. But other metrics that conform to using a hamming distance might be imple...

Re: Windows Application Faulting Event from php calling new Imagick($pdfFn);

Imagemagick 6.9.3.7 is ancient. That could be part of the issue. But, mainly, you need to have Ghostscript installed where Imagemagick and PHP can find it. Often you need to edit the delegates.xml file to put the full path to gs in the command=""gs" for PHP to find it. You may also have to...

Re: Combining multipage Tiffs with "2 dimension"

Looking at your expected result image in ImageJ, it appears to be a special format for ImageJ. I tried to recreate it in Imagemagick by combining the two input images as the red and green channels with a blue channel set to 0. But ImageJ did not open it the same way as your image. The property, chan...
