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...

Re: Display image from command line

convert image.gif show: Attempts to work but results in the message: Error loading ..... photoviewer.dll It seems photoviewer is a WIndows 7 dll not supported by XP.

Display image from command line

There is a way for the final result of a convert to be displayed by Windows XP.
I discovered this by accident some time ago and have forgotten. Various searches
on the ImageMagick sites do not reveal the method.

a) How is it done?
b) Why is it so difficult to find?

Re: Fred's autocaption and rectangles

Sorry about the link. It no longer worked for me either.
Have had the ISP fix it and also provide a proper directory listing to the browser.

Re: Fred's autocaption and rectangles

There is no ftp access to the link, you have to use your browser which should display the image(s)
and then you can download them from the browser if you wish.

Re: Fred's autocaption and rectangles

I refer to the -s option, providing the size of a text square area. I have not grasped the placement algorithm as yet but I thought it tried to find an area with the largest area of background colour and place the text there - so that it covered least amount of image information. If the `uncluttered...

Fred's autocaption and rectangles

Placing numeric identifiers in a grid (eg a map grid) mostly involves a rectangular area for the number eg a three digit number. Requiring a square area for the caption could result in sub-optimal placement in fairly crowded areas. I wonder if anyone has modified (or can suggest how to) Fred's autoc...

Fred's autocaption and semi-transparency

If an image is somewhat crowded, a caption will overlap other detail. So it would be helpful if the caption could be semi-transparent. I tried this colour: -c "rgb(111,198,242,0.2)" and this -c "rgb(111,198,242,0.8)" with both gif and png files. The caption colour was opaque in all cases. Is there a...

Re: Fred's autocaption script failed

Brilliant! This works: tr -cs "[:digit:]" "[ *]". The script places the number nicely in a crowded space. For the second part of the original post. An image contains a 15x10 (or similar) overlaid grid. The background is white. A pre-determined number is to be placed in each grid cell. The number can...
