Re: Create stack of identical images with transparent overlap

Why don't you show the command you used? You need to make the white background transparent. But the background isn't exactly white. magick orig1skdd.jpg -fill White -fuzz 10% -draw "color 0,0 floodfill" -fuzz 0 -transparent White t.png Then t.png can be composited over itself. You can do the whole j...

Re: Unable to trim borders of a scanned document

The order is wrong. You need to read the image before you can input it. "-fuzz" modifies "-trim", so should come before it, not afterwards. The image is noisy. This works:

Code: Select all

convert invoice.png -despeckle -despeckle -fuzz 90% -trim +repage out.png

Use the prefix "TIFF64:" on the output.

Re: -radial-blur unrecognized

It has been renamed to "-rotational-blur".

@Fred: This new option is not documented in http://www.imagemagick.org/www/script/c ... adial-blur . Can you fix this, please?

Re: transparency changes in IM 7

Please show your inputs, not just the outputs.

I never use "composite" for anything. I use "convert" for v6 or "magick" for v7, with the "-composite" operation. This needs the two inputs in the opposite order.

Re: Using alpha of programmatically generated image for clipping mask of RGBA background color label?

A simplified version so we don't need to do "label:" and "-splice" etc twice: magick ^ -background "#3399FF" -fill "#F26322" -font "Segoe-UI-Semibold" -pointsize "15" label:"Text String" ^ -gravity southeast -splice 6x4 ^ -gravity northwest -splice 6x2 ^ ^( +clone ^ -fill White -colorize 100 ^ -draw...

Re: transparency changes in IM 7

See the v7 porting guide: http://www.imagemagick.org/script/porting.php Reading gray-scale images generate an image with only one channel. If that image is to then accept color the -colorspace setting needs to be applied to expand the one channel into separate RGB (or other) channels. So, insert "-c...

Re: Using alpha of programmatically generated image for clipping mask of RGBA background color label?

I suggest you split long commands into logical lines. This makes them easier to build, understand, and debug. For example: %IMG7%magick ^ -background "#3399FF" -fill "#F26322" -font "Segoe-UI-Semibold" -pointsize "15" label:"Text String" ^ -gravity southeast -splice 6x4 ^ -gravity northwest -splice ...

Re: Converting HEIC images with Display P3 color profile

@zkarj: Can your version of IM write HEIC files?

Code: Select all

f:\web\im>%IMG7%magick -list format |grep -i HEIC
     HEIC* HEIC      r--   High Efficiency Image Format (1.4.0)
This version (v7.0.8-64 on Windows 8.1) can read HEIC, but not write it.

Re: How to make a image in desired shape in imagemagick?

What version of IM, on what platform?

Your "%ProgramFiles%" suggests you are using Windows, but you escape \( and \) which suggests you are using bash. That is a problem. If you use Windows, see http://www.imagemagick.org/Usage/windows/

Re: Creating a color palette from an specifc color

"Palette" is a technical term, meaning that pixel numbers do not directly define colours. Instead, each pixel has a single number that is an index to a table (a "palette") of colours. IM does not supply tools to directly edit palettes. But perhaps you simply want to change colours in an image, regar...

Re: Lighten dark areas only?

As Fred says, you can apply Photoshop operations to a clut or hald-clut, then use that in IM. In IM alone, you can get as much contrast as you want. For example, change "-evaluate Pow 0.6" to "-evaluate Multiply 20". Then what was 5% becomes 100%. http://snibgo.com/imforums/samara_out2.jpg I think t...

Re: Lighten dark areas only?

I don't know what the problem is.

You say you tried the level and gamma methods, and IM worked. Did you use the same filename? The same "magick" command?

I suggest you show the complete BAT file, with all three commands.

What version of IM do you use?
