Re: IM copy_opacity example seems to fail - Solved

The GUI being used to check the image was PSP-7. A vague recollection of a GUI upgrade being provided 10 or more years ago, stimulated an extensive search through disks. There was in fact an upgrade and it had not been applied to the GUI on the PC being used. Upon performing the upgrade, the image d...

Re: IM copy_opacity example seems to fail

There seems to be a serious gap in my knowledge of transparency. Repeating the example script in the IM V6 Composting examples: convert -size 70x70 xc:black -fill white -draw 'circle 35,35 35,5' \ -fill black -draw 'circle 28,30 35,5' moon_mask.gif convert -size 70x70 plasma:white-dodgerblue moon_ma...

Re: How can "show:", "win:" be made to work

In the previous post, the error message was a windows message board with title RUNDLL. But OOPS! I failed to use `verbose' and so missed the IM error messages which are: convert -verbose -size 100x100 xc:white "win:" xc:white=>white XC 100x100 100x100+0+0 16-bit sRGB 0.000u 0:00.031 xc:white=>C:/WIN...

Re: How can "show:", "win:" be made to work

Thanks for the replies. I have XP and it does not have Windows Photo Viewer but it has a viewer the title bar of which declares "Windows Picture and Fax Viewer". Actually, to run other than clicking on a file that is associated with it is to execute: C:/WINDOWS/system32/rundll32.exe "c:/windows/syst...

Re: IM copy_opacity example seems to fail

To Fred: My first post contains the two scripts I used which are copies from the imagemagick examples. The IM example actually has `CopyOpacity', no hyphen. But I tried both with the same lack of result. It is strange that copy_opacity does seem to work in your textcleaner. I used it a couple of day...

How can "show:", "win:" be made to work

"win:"/"show:" used to work and were very useful when debugging a command or script.
However they don't seem to work with Windows XP.

Are there files in an existing installation that can be patched (eg by me) in order
to make one of win:/show: work?

Version: ImageMagick 6.8.7-4 2013-10-26 Q16 I use a Korn Shell command line interpreter running under Windows XP and have been running IM scripts for many years. EG several of Fred's scripts run without change. But "to be sure to be sure" I ran it again in XP command mode and it still failed. The re...

Re: Contrast gradient - solutions

Thanks again snibgo and Fred.

Both suggestions work quite well. Fred's text tool, being a complete script is naturally, easy to use `out of the box'.

Re: Contrast gradient - solution

Thanks snibgo, most helpful. Although I have used IM off and on for years, sometimes with quite complex problems, there are still many options I have never seen. Even after searching for the %[pixel:...] option just now, all I could find was %[pixel: expression] but had no luck finding a list of val...

Contrast gradient

I photographed a notice at an awkward angle (this is actually a representative test case). Using the perspective operator with convert, the image aligned OK. The image remains darker to the right (as expected). I want to OCR the image for which reduction to two colours is best. However the right sid...

Re: Problem with Fred's Auto-Captions

Downloading IM 6.8.4-3 fixed the caption problem (thanks) even though ImageMagick did not pass the Installation test. That is, `convert wizard.jpg win:' resulted in display of the Windows XP `Open With' dialogue box with the instruction: Choose the program you wish to open the file: File: magick-440...

Transparent overlay of grid lines imperfect

If a constant size grid is to be applied to a large number of images, a couple of ways to do it are: a) Make an image of the grid on say a white background, then overlay that grid onto the images: eg after creating the grid file convert mapin.gif \ \( gridfile.gif -crop 2819x1542+0+0 -repage 0x0+0+0...
