Re: drawing line using relative coordinate like 'bottom left'

I am writing a script that takes a x,y coordinate from a text file then draws a circle around that position. It also picks up label from the same text file for that x,y coordinate and appends it at the bottom of image. Now, I want to draw a line from that x,y position to bottom of image. As snibgo ...

Re: Skew Image by only 1 pixel

I want to skew the top side of an image by 1 pixel to the right. You can use "-distort affine" to get that result, while letting ImageMagick calculate the angle. convert in.tiff -virtual-pixel black +distort affine "0,0 1,0 0,%[h] 0,%[h] 1,%[h] 1,%[h]" -shave 1 out.tiff That essentially slides the ...

Re: append colored text to an image

My requirement is that I want to add colored text with white background to bottom of file . Can this be done using one command rather than creating a separate text image then using append ? Within a single command you can create a label with colored text on a white background, and append that label...

Re: Select more than one layer from TIFF and output a flattened JPG

Thx, will give that a try. The answer snibgo gave above is about as simple as you can get. Keep in mind you can include more than one index inside the square brackets, and those indexes can be in the order you want to read the images. This command would read in the second image before the first... ...

Re: convert output changes with recent update

A recent ImageMagick update (to version 7.0.8-47) on my system has resulted in production of errant results from a script I've been running for a few months now. The script overlays onto an image some text that I download from the internet at regular intervals, adding a blurred shadow effect to the...

Re: Problem with -blur on transparent with 7.0.8-47

Convolution in IMv7 had a bug when dealing with alpha channels. The bug is fixed in -47. The bug I'm describing just appeared in -47. Using -channel RGB tells IM to ignore the alpha channel when blurring. It should, as Fred suggests, fix the problem you reported. Using "-channel RGB" before the blu...

Re: Removing All Shades of Grey from an Image

After more testing I realized that I can't entirely drop the black channel from the CYMK separation. [...] To my novice eyes, adding a second +clone line and fuzzing the K-channel to a few percentage points of #000000 would work, but I'm not sure how to pull that off and then combine both into the ...

Re: Annotate is repeating on every image.

The blocks are white (FFFFFF) for example, in reality, I'll use different colors, but for simplicity, I'm using FFFFFF here. I need the first and second block to only print 1 and 2 respectively without having other numbers written on top. When using "-annotate" you can include FX expressions within...

We can make it slightly faster (and use less memory) by separating just the CMY channels, rather then separating them all then deleting the K channel:
Thanks. I noticed that and was editing probably as you were replying. :)
