jpg does not support transparency and neither does certain png formats. you need to use PNG32 to preserve transparency. and GIF supports only binary transparency. So if you eps file has partial transparency then you must use PNG32. see http://www.imagemagick.org/Usage/formats/#png_formats But again ...

sorry I don't think I can be of much help. First your first web site does not work completely. When I try to change the color I get error messages or no change. Second I have no Idea how to compare the second site with the first. Nor if I did, I would not know how one processed the images vs how the...

I now have a script, aspectpad, to do this. Get it at my web site below.

The times reported are how long it took to read the image format, not the total user and elapsed time. Sorry, I am not making my question clear. logo_tmp.png PNG 640x480 640x480+0+0 8-bit DirectClass 72.9KiB 0.010u 0:00.020 The last one: 0:00.020 is this hrs:min as fraction so .02 minutes or someth...

That is user and elapsed time. OK. But I must not understand the units as it does not seem consistent with the time function time convert logo: -blur 0x50 logo_tmp.png real 0m9.973s user 0m8.935s sys 0m0.085s identify logo_tmp.png logo_tmp.png PNG 640x480 640x480+0+0 8-bit DirectClass 72.9KiB 0.010...

OK, but feel free to get other opinions if you want. But still would like to know what are the last two columns in the identify. identify rose7.tif rose7.tif[0] TIFF 70x46 70x46+0+0 8-bit DirectClass 68.4KiB 0.000u 0:00.000 rose7.tif[1] TIFF 70x46 70x46+0+0 8-bit DirectClass 68.4KiB 0.000u 0:00.000 ...

1) OK. But seems to me that kB or KB (1000) would be the prefered format for image sizes since they are not restricted to powers of two. See http://en.wikipedia.org/wiki/Kilobytes excerpt below. "Some have suggested that the capitalized prefix "K" be used to distinguish this quantity...

This is kind of a kludge. It use an inplace variable calculation. But is one long command line. It resizes the rose: image to be 1/4 the size of the logo: image and places it in the middle of the logo: image convert logo: \ \( rose: -resize $(convert logo: -format "%[fx:.25*w]x%[fx:.25*h]"...

-annotate uses whatever pointsize you specify and places it according to -gravity and the -annotate coordinate arguments. It knows nothing about the image size. Thus if you have too large a pointsize, it will overflow the image. The only way I know to do what you want is to specify the width (in pix...

It appears that the format for identify has changed. convert rose: rose: rose: rose: rose: rose: rose: rose7.tif identify rose7.tif rose7.tif[0] TIFF 70x46 70x46+0+0 8-bit DirectClass 68.4KiB 0.000u 0:00.000 rose7.tif[1] TIFF 70x46 70x46+0+0 8-bit DirectClass 68.4KiB 0.000u 0:00.000 rose7.tif[2] TIF...

The best way is to write a script to loop over all your frames and select every 14 one and merge them into one image (if that is what you need rather than separate images). Use the [#] syntax, such as image.tif[0] for the first frame. See http://www.imagemagick.org/Usage/basics/#sequence However, yo...

Sorry I misunderstood. I don't think you can do that without computing variables for the size of the inputimage and then using those variables in the resize. For example in Unix (sorry I am not a Windows user): ww=`convert inputimage.jpg -format "%[fx:0.2*w]" info:` hh=`convert inputimage....

composite.exe -gravity SouthWest overlayimage.png inputimage.jpg outputimage.jpg You need to use parenthesis processing. Windows syntax: convert.exe inputimage.jpg ( overlayimage.png -resize 20% ) -gravity SouthWest -composite outputimage.jpg see parenthesis processing http://www.imagemagick.org/Us...

don't know too much about eps files. But have you tried converting it to RGB when reading it in by using -colorspace RGB where you have -colorspace CMYK

you can use clone and parenthesis processing (see http://www.imagemagick.org/Usage/basics/#image_seq ) BUT you cannot recombine (-combine) the images if they are not the same size. So you would have to pad them back to the same size first. convert zelda3.png -separate \ \( -clone 0 -resize 75% -grav...
