Glad that helps. But note that this isn't "close to the original" because there is no original. There are only different renderings of the raw (mosaiced) image, which might include a JPEG rendering made by the camera or by other software.

Sorry, what does that mean? How can an image file be "empty"? Perhaps you mean it has a certain number of pixels but they are all transparent. But I don't think you mean that.

dcraw can write PGM or TIFF format only. It can't create JPG files. dcraw (and other raw processors) have many controls. IM doesn't provide simple access to those controls. For basic conversion to sRGB I suggest: dcraw -6 -T -w -O out.tiff in.CR2 This makes a TIFF file, which IM can then convert to ...

I suspect a colour-balance problem.

You don't say what command you used, or what delegate your version of IM is using to process the raw file. If you browse this problem in these forums, you will find my general advice: use a program such as dcraw directly to process raw files.

Beware that "depth" might mean bits/channel/pixel, eg 8, or total bits/pixel, which might be 32 when there are four channels.

Software (including IM) should be explicit which definition they use, but rarely is.

But what version of Ghostscript? See Fred's advice above.

See the documentation http://www.imagemagick.org/script/comma ... ptions.php and search for "bilevel".

What version of IM fails? You write "converting a PNG to a SCG" but I assume you mean "SVG". There does seem to be a problem. With v7.0.8-64 on Windows 8.1: magick xc: x.svg Fatal User Error 1002: Deadlock due to omp_set_lock being called on lock already owned by thread EDIT to a...

Which part of your code writes a file?

When searching source code, I suggest you start with PerlMagick\Magick.xs. That shows the call to ColorizeImage(...) A grep of magickcore\*.h finds that function in fx.h.

How about "+distort affine" which creates canvas dimensions and offsets, and then "-layers mosaic" to use that metadata to make the final image: convert in.png -alpha set -virtual-pixel transparent +distort affine "1,1 50,50 1,50 50,100 50,1 100,50" +write info: -backgr...

I suggest: Or:

Parameter 'fill' corresponds to the command line's 'value': as you say, it appears to be a color[1], ... I'm not saying that. I expect perl Colorize "fill" corresponds to the CLI "-fill", which is a colour, and perl Colorize "blend" corresponds to CLI "-colorize v...

I think the OP wants an average image, not a simple number. My suggestion for 1x1 images is only for development and testing.

On $image->Colorize, see http://www.imagemagick.org/script/comma ... p#colorize . Perhaps the blend parameter corresponds to the command-line "value".

But "-colorize" can't create transparency.
