Re: `identify -verbose -ping` now runs slow

Wow, you people are quick!

Is there any chance of still making identify a little smarter so it does run quicker? I miss getting the verbose information quickly.

For now, I'd be content in hearing it's at least somewhere on your to do list.

Thanks,
Gary

`identify -verbose -ping` now runs slow

In previous versions, when identify was called with -ping and -verbose at the same time, the whole verbose listing was displayed but some of the information like number of colors, etc. was incomplete because -ping caused it to run really fast! I'm trying to determine if a tiff is a monochrome image....

I see that the number of values in the histogram does match the number of unique colors, but I'd rather not have to count them to find how many there are. To me it seems contradictory to state 256 colors when there are only 2 unique colors. After some digging, I know that's because of the LZW compre...

Unique Colors

I have a tiff file with LZW compression. When I do an identify -verbose on it I get Colors: 256. When I do an identify -format %k on it, I get 2. Another software program also reports 256, so I'm assuming that's more or less what the LZW compression gives (at least in this case). Would it be possibl...

Try using -monochrome after the -density and -resize options. Since these are operators, when monochrome is done first, it gets converted fine. Next, when -density is done, it may actually convert the monochrome image to grayscale or color. Since it is no longer monochrome, then compression cannot b...

Tiff split

I have a 74 page tiff file that I want to split into individual pages. It's currently at 256 colors with LZW compression. From my understanding, if I do convert a.tif b%03d.tif it will load all pages as uncompressed tiffs into memory and once that is done it will output one page at a time. That's a ...

On second thought, standard in works more like

Code: Select all

  $cmd = 'echo ' . $img . ' | /usr/local/bin/identify -format "%x,%y" -';
I just tried
cat a.gif | identify -format "%x,%y" -
and it worked great.

If you want to read the image from standard in, you need to use a hyphen. You should be able to do something along the lines of identify -format "%x %y" gif:- $stringContentOfImage You may be able to specify just the "-" without the whole "gif:-", but I don't know that for sure. You can find more in...

First, Anthony, thanks for your web page (which I've referenced numerous times) and for all your posts on the forum. In the documentation at http://www.imagemagick.org/script/command-line-processing.php#setting it says that -monochrom is a setting. If this is an operator as you say it is and as I se...

monochrome, resample, and compress - why does order matter?

I have a monochrome tiff that I want to resample to a lower resolution. If I do "convert a.tif -resample 100x100 -monochrome -compress group4" it works as I expect producing a monochrome tiff with group4 compression. If I do "convert a.tif -monochrome -compress group4 -resample 100x100" it produces ...

It worked previously in v6.2.6 or so. It's nice to do that when I want density, etc., but don't need all the color info. As a side, it would be nice to not have the color info, etc. displayed when it hasn't been properly populated.

identify -verbose -ping on win32 memory error

When I run "identify -verbose -ping a.jpg" on W2K with v6.2.8 08/02/06 (the current installation file) I get a memory could not be "written" error.
This happens after the Geometry is displayed and before the Type is displayed. Without -ping it works fine.

Thanks,
Gary

Heap Corruption

I likewise was getting occasional errors from my VB application that uses the ImageMagickObject. After talking with Microsoft, we put a debugger on the code and it was producing heap corruption. I decided to run the debugger on MagickCMD.exe and it did the same thing. The command I ran was simply Ma...
