with new version 64 IM crashes (on 64bit Win7) with popup message: ImageMagick Studio library and utility program has stopped working A problem caused the program to stop working correctly, Please close the program. I downloaded and used "ImageMagick-7.0.8-64-portable-Q16-x64.zip" When I a...

On my 64bit Win7 system I found no TdrDelay registry entry.

Furthermore I wonder why this warning appears only recently.
In the past IM worked WITHOUT TdrDelay change.

What was changed in IM?

yes, it looks like as if I am getting the desired result....but approx 20 times slower. For resizing a photo tooks now ~10seconds (in comparison to 0.5 seconds before). So what causes the fallback from GPU to CPU? I did not change something extraordinary in my 64bit Win7 system in comparison to time...

When I want to convert (resize) a *.png image under 64bit Win7 then sometimes (mostly but not always) the following error appears: convert: clBuildProgram failed. (-11) @ warning/opencl.c/CompileOpenCLKernel/1395. Hmm, ImageMagick worked fine with the same command on the same computer in the past. S...

Many cameras create a photo file with originally portrait orientation by capturing it pyhsically in landscape mode and create header tag that it is rotated by 90 (or 270 deg). When such a *.jpg file is opened in a (most) picture viewer, then the picture viewer reads at first the orientation header t...

Assume I have a *.jpg picture and want to

1.) sharpen it by lets say 10% (whatever it means)

2.) Increase saturation by 12%

How can I achieve the two tasks with ImageMagick?

Ok, so "-precision 16" is completely useless since I get the number of Bytes already with "set BYTES=%%~zF"

Ok, meanwhile I have fixed the bug. The script runs for filtering images for width and height. Now there is still a problem with the size. Originally in one of the first posts the "set BYTES=%%~zF" trick was suggested. Then fmw42 suggested -precision 16 solution. From my point of view that...

Thank you for all the suggestions. However when I try to setup a full script I am experiencing errors like "Missing operator". Furthermore I wonder how I can use the "-precision 16" parameter to filter and count the files matching the threshold. Have a look at the following batch...

@snibgo:

Ok, thank you.
You said:

>The operating-system "%~zF" can do that

What does that mean? Can I switch somehow from inside the batch script the format how the WinOS returns the number of bytes?

Assume I have I big dirextory tree with lots of images inside. The top node starts at the dir D:\archive\images\personal\ Now I want to count (resp. to log into logfile) all *.jpg images (only) which have a file size of e.g. 300KB and more. Secondly I want to do a similar search but this time I want...

Assume I have a couple of *.jpg pictures with a big EXIF header each. This EXIF headers contains (beside other meta information) some timestamp fields: date/time date/time original date/time digitalized .....? How excatly can I (with ImageMagick) a) strip off all (only) timestamp header fields? b) a...

ok. Thx

Thank you for clarification.

However after ImageMagick decompressed (internally) the *.jpg and applied the -chop command a re-compression takes place:

At which compression level (by default)?

Assume I want a compression level of 97%: How can I specify this in the convert command above?
