The write command may want to modify the image, to prepare it for output. For example the image may have more than 256 colours but the output format needs 256 or fewer. "-write" will modify the image in memory, then write it to disk. Any subsequent processing (including any more writes) will use ...

I had forgotten about the PNG -quality thing, I re-ran the command (on Windows) with -quality 05 for the PNG output files and it ran in 10 seconds. The "loading" entry no longer appears for PNG output, without looking up the documentation I would assume that previously ImageMagick was doing some ...

I just installed ImageMagick-7.0.3-Q8 and ImageMagick-7.0.3-Q16, the same command (on the Windows machine) took ~26 seconds.

Load/Image//tmp[magick-19009cL_UcmVI5geL]: It seems to be using a temporary image on disk. This happens when there is not enough real memory. Can you try the same command on a computer with more memory? Can you upload test.jpg, or any image that has the problem, to somewhere like dropbox.com and ...

I attempted to use MPR again as follows: time \ convert -monitor 'test.jpg' -write mpr:foo +delete \ \( mpr:foo -resize 3000x -quality 85 \ +write 'test 3000.webp' \ +write 'test 3000.jpeg' \ -write 'test 3000.png' \ \) \ \( mpr:foo -resize 2000x -quality 85 \ +write 'test 2000.webp' \ +write 'test ...

Chunks like this: \(+clone -quality 85 -write 'test 3000.webp' +delete \) \ \( +clone -quality 85 -write '/test 3000.jpeg' +delete \) \ \( +clone -quality 85 -write 'test 3000.png' +delete \) \ ... can be replaced by: -quality 85 +write 'test 3000.webp' +write '/test 3000.jpeg' -write 'test 3000 ...

Hi guys, I have a bit of a plea to help me improve the performance of a command. What I am trying to do is this: Given a source image, resize it to various sizes, and for each size save it in a few different formats. Initially I did this by the means of some nested loops in PHP, having a different ...

I'm sorry for the delay in replying, I had some connectivity issues. But, while I had the down time I did some testing. And I discovered that by converting my cluts to 8bpc TIFFs the problem goes away. Possibly the same would apply if I used 8bpc PNG also, but I haven't tested that, I'm just happy ...

Try replacing libpng-1.2.50 with the current libpng-1.2.56. The "1.2.50" that you are running is probably not really libpng-1.2.50 but rather Ubuntu's "patched" 1.2.50 which might truncate the palette, due to an incorrectly-applied recent security patch. This might be something I am unable to do ...

Did you check your versions of libjpeg and libpng? see convert list format Sorry, I overlooked that. $ convert -list format Format Mode Description ------------------------------------------------------------------------------- 3FR r-- Hasselblad CFV/H3D39II A* rw+ Raw alpha samples AAI* rw+ AAI ...

I'm not completely sure how to determine how to keep an eye on ImageMagicks's temp file creation. I grep'd policy.xml which suggested that the tmp dir is /tmp, I watched the folder while I generated all the images within the application and it didn't look like any temp files are being created there ...

The hald image was generated a long time ago, using a command like convert hald:8 hald.png this image was then modified in Photoshop and saved as a PNG (I don't want my careful colours to be messed up by JPEG compression!). I can't imagine that the hald image is causing the problem, as the problem ...

Hi guys and gals, I have a bit of a problem with ImageMagick that I've been wrestling with for a few hours, and I think it's time I got some help. When editing an image with the imagick PHP extension I occasionally get a seemingly random spattering of black dots on my output image. For example, I ...

I just switched up to ImageMagick 6.9.2-6 Q16 x64 and the problem is gone!



That was a nice and simple fix, thanks for the help

What I am Trying To Do: I am trying to create a speedometer. I have a speedometer background image, and a needle image. I want to rotate the needle image so that it points at the correct speed, rescale it, and place it on the speedometer image. The needle should be rotated around the base of the ...
