Re: PAID: Problem with IMagick, Huge temp files, LF a developer

Okay, 36.13 * 25 inches, at 1500 pixels per inch, at 8 bytes per pixel, needs 16.3 GB. This is close to the size of your 19 GB temporary files. You haven't showed your ImageMagick command. I suppose it has "-density 1500 -units PixelsPerInch". So I suppose IM is doing what you tell it to do, and IM ...

Re: PAID: Problem with IMagick, Huge temp files, LF a developer

@AnavPT: I am trying to reproduce your problem with large temporary files. It may be a combination of a PDF with large physical dimensions (in inches), with an IM command that rasterizes with a large density (1500 pixels per inch). But I can only confirm this if you show the IM command, and PDF, tha...

On Ghostscript options, see https://www.ghostscript.com/doc/current/Use.htm#Options

Those are large numbers. A more typical "-r" option would be "150x150".

Please show the ImageMagick command, and input PDF, that creates that Ghostscript command.

Re: why I cannot use installed fonts

For example, on my Windows 8.1, one entry is: Font: FreesiaUPC-Bold-Italic family: FreesiaUPC style: Italic stretch: Normal weight: ...

Re: colorspace forced to Gray if pixels are all grayscale

For JPG, use "-type truecolor" to force 3-channel JPEGs.

IM has always tried to minimize output filesizes, eg by recognizing when all pixels are gray, so only one channel is neeed. But IM's methods for doing this have changed.

Re: how do I make a multi resolution .ico file?

When you run the batch script, what do you actually type at the command line? The script expects the first argument to be the name of the file you want processed. Are you supplying that filename? The one-liner you posted won't work if pasted at the command line, because it uses %~1 for the input fil...

Re: Increasing Color Depth

"-colors 16" will find no more than 16 colours that, when your image is remapped to those colours, introduce the least overall distortion. This will change many of the colors in your image, obviously. If you want to guarantee that white stays white, you can use "-colors 16 -unique-colors", then add ...

Re: Extract Clipping Image

We can turn all fully-transparent pixels into transparent red. Then we extract the alpha channel, dilate the white areas, and copy the opacity back to the image. The result has a red outline. Windows BAT script: magick ^ 1584707760age.jpg ^ -profile sRGB.icc ^ -alpha transparent ^ -clip -alpha opaqu...

Re: Compression level (of tiff files)

TIFF with ZIP compression is lossless. I don't think there are any parameters that will improve the ZIP compression rate. You could reduce the number of colours, but that would not be lossless. If your build uses old versions of libraries, it's probably a good idea to rebuild with current libraries....

Re: Mogrify

C:>mogrify -format file1.tif file1.png That is a bad command. In "mogrify", "-format" is the option for the desired output format, so that would be PNG or JPG or whatever. I notice that you use ".tif" (with one f) as an extension. That is fine. It might explain why the command with "*.tiff" (with t...
