Re: Request for a new parameter to the -canvas command.

I tried a new command with the parameter (-canvas longest 220mm center) The original size canvas of 142x214mm changed incorrectly to 12x10 mm. Tell me what I'm doing wrong.

Request for a new parameter to the -canvas command.

Good afternoon! I want to make a request to add the parameters "on the long side" ("on the short side") to the -canvas command, as it is done in the -resize longest size (-resize shortest size) command. This parameter allows you to change the size (canvas) of multi-page tif files, regardless of the ...

Use of -levels2 options

In the new version 7.70 of nconvert, the command "-levels2" has appeared, please help us understand the parameters of this command. The logic of these 5 parameters is not quite clear. Describe them in more detail and preferably with examples.

Re: Processing of multi-page TIFF files.

OK, I'll try to do this via the FOR command in CMD. Thanks for the idea.

Re: Processing of multi-page TIFF files.

Now I checked it on an array of multi-page tif files. And it turned out that the proposed set of commands works only on a single multi-page file. When you try to process an array of multiple multi-page files, the result is combined into a single file. Here is my example (for totalcommander) -rmeta -...

Re: Processing of multi-page TIFF files.

Thank you, everything worked fine! :) Now I have dealt with this issue. My mistake was putting the "-multi" command before the "-out tiff" command.

Re: Processing of multi-page TIFF files.

There are a number of tasks, such as resaving the tif with a different type of compression or deleting metadata. At the moment, I first split a multi-page file, then process it page by page, and then assemble it into a multi-page file. Is it possible to do this without pagination. If yes, please wri...

Processing of multi-page TIFF files.

Good day to all!
Please tell me if it is possible to use the converter utility to process and save a multi-page TIF file without having to parse it page by page? Any attempt I make to process a multi-page TIFF results in a single-page TIFF, and only pagination produces the result. :?

Add a detail parameter to the -binary floyd command

I want to contact the developer with a request. :!: At the moment, one of the binarization commands ( -binary floyd ) does not have a detail parameter (more precisely, the parameter is set by default to about 50-60%). :( The Floyd Steinberg binarization method allows you to use the detail parameter ...

Re: What to use instead of levels and curves

Yes, there are only 2 parameters now - the white point (W) and the black point(B). However, if the middle tone parameter is added to developers, it will simplify batch processing of similar scans. For example: "- autolevels -levels 000 165 255"

Re: What to use instead of levels and curves

It's complicated. I think it will be easier to add the "-levels" parameter medium tone (shadow) to the command. For example:- levels 15 145 210, where 15 is the black point (B), 145 is the mid - tone point (shadow), and 210 is the white point (W).

How to change the mid-tone parameter in a gray image (TIF)

Hi!
Task: Change the mid-tone parameter in a gray image without changing the parameters of light and dark tones.
Is there such a possibility in nconvert using its commands :?: , if not, is it possible to add a parameter to the "-levels " command? :wink:
