The usual arrangement (eg Gimp Color Curves) shows a histogram. The user can interactively edit curves, and Gimp will update the histogram ac...

Re: issue with the installer

...installed on a machine and copied to a folder... The installation creates registry entries about folders, so moving to a different folder will break it. For that, you need a "portable" version. See http://www.imagemagick.org/script/download.php#windows . However, pre-built portable ver...

Re: joining images of different dimensions with automatic resizing according to smallest

I am stacking them vertically using append operator. But there is white space at the bottom of B in result. At the right of B, surly? Sample inputs and output would clarify what you want. I don't think you can do this in a single command in v6. V7 can do the A and B problem in a single command, by ...

Re: FOSS to create 3D models in OBJ or FBX

IM is a 2D raster image processor. For 3D, use a 3D system such as Blender.

Re: ImageMagick7 runs much slower than version6

Multi-threading can be disabled per command, but HDRI is a build-level switch.

I use at least two versions of IM: HDRI when I need precision, and non-HDRI when I need speed. This may not be feasible on a shared server.

Re: Remove object from Image

For a Windows BAT script that searches quickly, see Searching an image . For a process module that searches even more quickly, see Process modules: multi-scale image search . This is available for all platforms, but needs IM to be re-built. For the OP problem, perhaps the logo is always the smallest...

No, IM can't write clipping paths. Gimp can.

Re: Specifying a maximum width for long caption text while for shorter strings occupying a shorter width?

You can insert "+write info:" at any point in the command. Another hint: insert "+write abc.png" anywhere. Very handy for debugging. The format can contain other characters, so we can do things like this: magick rose: -format FIRST=%@\n +write info: -border 10 -format SECOND=%@\n...

Re: Color issue when compositing sRGB image over CMYK background and saving as CMYK

CMYK and sRGB have different gamuts, meaning some colours in one colourspace have no unique corresponding colour in the other colorspace. This means that some colours (especially saturated colours) will change when they undergo the roundtrip CMYK->sRGB->CMYK. The sample-bg.jpg image undergoes that r...

Re: Trimming background and isolated pixels

There are many way to denoise an image. When the noise is small dark marks on a light background, we can blur then threshold. This finds the trimmed parameters from a denoised image, and uses those parameters on the input image. magick \ VII-3-Prussing-1982-072.tif \ \( +clone -blur 0x2 -threshold 5...

Re: IM 7 -background transparent

I suppose in those other cases alpha is already enabled. If the input image has any transparency, alpha will certainly be enabled.
