-evaluate multiply 0.5

works great, THANKS!

I'm trying make an image with transparency more see though. I'm using convert image.png -alpha on -channel a -evaluate set 50% out.png However, it removes the areas that were completely transparent and makes them 50%.. So, I'm losing the mask.. How can I keep the mask and bump up the rest of the alp...

Here is a pair.. http://www.ebay.com/itm/Holiday-Specs-F ... Sw4shX9FIJ

they have a lot of designs. It's actually pretty cool to look through.

Hi,

Dunno if you have seen these glasses that produce a 3D effect with Christmas tree lights.

Is there a way to reproduce this effect with IM?

I've seen a star like effect, but this is a bit more complicated pattern

I was just watching this video on how broken color blur is

and noticed the same problem with IM -blur and -gaussian-blur



Notice the dark line in the middle.

Is there an easy way to fix this?

having a problem with batch file processing (bash / linux)
Most images are fine, but a few are incomplete, corrupted during transfer.

How can I test and reject the bad images?

Interesting, I'll look forward to that page..

The WSJ article, I forget can only be accessed from google.

https://www.google.com/search?q=wjs+stipple (should be first result)

it's more of a dot pattern.

Wondering if this is possible with IM. Either stipple like WSJ http://www.wsj.com/articles/SB10001424052748704207504575129961786135180 or engraving like this one http://blog.spoongraphics.co.uk/freebies/free-engraved-illustration-effect-action-for-photoshop looks like that just uses a few textures?

I see what you mean.. The 8x8 was just the enlargement of the detail, post processing.... but it's the 2x2 patchwork that is the real problem

I'm guessing that it's rendered at half the size then enlarged without the regard for contour.

50% then 200% resize does help somewhat.

Hi, I'm using another program that is generating images, however, they have a lot of pixelated noise. Here is an example: https://cloud.githubusercontent.com/assets/13002561/19278731/feb9c1ac-9010-11e6-887b-d601c89e7c1e.png Any advice on removing this pattern, or smoothing the image. The only smooth...

I was having trouble with special characters in the command line.
My bigger question is how is including a text file for annotation a security problem?
Can commands be embedded in that?

Hi, I'm trying to come to terms with the new policy file updates, and how to fix my scripts that have been broken by it. specifically <policy domain="path" rights="none" pattern="@*" /> I'm thinking the LABEL and TEXT are also a concern. An example of how I use it would be -annotate @text.txt So, ye...

I find the presence of CURL in delegates disturbing. I'd like to ensure no files start remote connections as well.

For those that operate a web service, you might want to look at this.

I sorta doubt this is a complete list, hoping we can identify what else in the delegates go beyond image conversion.

I'm looking for a way to automatically remove text from an image.

I've seen a javascript project that can do it ( http://projectnaptha.com/ )

It uses OCR and then an inpaint method.

I'm curious is there is another way, specifically, server side.
