Re: cache exhausted

You upgraded to 6.7.8-9? I suggest a more recent version.

Your "list resource" seems to show the Area is limited to 1B (one byte), and Disk to 16B (sixteen bytes). Perhaps the entries in policy.xml are being misread. Try changing "gb" to "GiB".

Re: Failure to Execute convert with tmap in R

I downloaded from the main ImageMagick site the version for Windows 64-bit: ImageMagick-7.0.8-58-Q16-x64-dll.exe. I then installed through the standard UI with options to put it in the system path and old versions. That seems fine. And we have established that you are not accidentally running Micro...

Re: Failure to Execute convert with tmap in R

convert logo: logo.gif generates nothing--no warning, but also no product. Did you issue that command at the Windows Console aka Command Line? If so, then don't worry about R and tmap for now, because ImageMagick isn't working properly. My mistake, I should have put a colon after NULL: convert rose...

Re: gif speed is very fast

I don't think IM will automatically set the delay rate. You can get this from ffmpeg or ffprobe: ffprobe ball4.mov : : Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'ball4.mov': Metadata: major_brand : qt minor_version : 512 compatible_brands: qt creation_time : 1970-01-01 00:00:00 Duration: 00:00:00.04, ...

Re: Failure to Execute convert with tmap in R

What version of IM? On what platform? I assume Windows of some sort. I know nothing about tmap or R. Your paths have mixed forward-slash and reverse-slash, and a double-slash. These may work, but are unwise. If your PNG files are too large, this might cause a failure. Does the command work at the co...

Re: cr2 to gif giving different Geometry metadata

With IM v6.9.2-6, dcraw is extracting all the pixels from the sensor, as it does by default.

With IM v7.0.8.58, it is using a built-in delegate. "magick -version" with probably show libraw. I don't know what that delegate does, but it is clearly cropping the full sensor.

Re: cr2 to gif giving different Geometry metadata

I suppose the different versions of IM are using different delegates. Add "-verbose" to see. Camera sensors are larger than the nominal size in pixels. Exiftool tells us your camera (Canon Powershot SX50 HS) is nominally 4000x3000, but that is a crop from a 4176x3062 sensor. "identify" tells you wha...

Re: [Magick++] Image constructor bug

Exactly what version of IM? What does "magick -version" say?

I suggest you post a complete but minimal program that shows the problem. Then we can try to reproduce the problem.

Re: How to handle invalid color profiles

I suppose it depends on what you want to test for. In this case, the image has 3 channels but the ICC is for 4 channels. This is technically valid, but we might say it suggests a problem.

IM can read the image and write a profile. exiftool can tell us the profile has 4 channels.

Re: Compose CMYK image from layers

By magick, of course.

For a better answer, see the source code in composite.c and follow the trail for GetPixelGreen() etc. Then (if in v7) you will see access is via the image channel_map structure.

Re: What's the amount of information that I can extract

... the amount of information that you can get with "identify -verbose" but I am not sure if I can get any more. What more information do you want? "identify -verbose" gives most or all of the metadata that was recorded in the input image file. In addition, it calculates statistics about the image:...
