            Then create a text gif.:

            convert -background transparent -fill yellow label:Rose label_white.gif

            Then compose them together using difference:

            can graphicsmagick import (screenshot) several snaps per second?
            Asked 2022-Feb-18 at 13:42

            I've read in the http://www.graphicsmagick.org/GraphicsMagick.html#details-snaps that it can produce several screenshots in a row, eventually with a desired pause time inbetween. However it seems that either I don't understand how to use it or it can't even do several screenshots with 1 second delay. The command I tried is: gm import -snaps 10 -pause 1 -window root ./"screenshot-$(date +%d_%m_%Y-%H:%M:%S).png"

            But this above command other than waiting 10 seconds and producing 1 screenshot with the initial screen it does not do what I read it should.

            So, can gm import do several screenshots with a delay ? if so can it do more than 1 screenshot in a second ?

            I'm trying to get GraphicsMagick to work on a heroku-20 stack, but am running into issues.

            All the buildpacks I could find either were not working on the 20 stack, or if they did, they didn't include freetype support.

            ImageMagick / GraphicsMagick / libvips Images randomly corrupted
            Asked 2021-Aug-05 at 10:43

            We are using ImageMagick for resizing/thumbnailing JPGs to a specific size. The source file is loaded via HTTP. It's working as expected, but from time to time some images are partially broken.

            We already tried different software like GraphicsMagick or VIPS, but the problem is still there. It also only seems to happen if there are parallel processes. So the whole script is locked via sempahores, but it also does not help

            We found multiple similar problems, but all without any solution: https://legacy.imagemagick.org/discourse-server/viewtopic.php?t=22506

            We also wonder, why it is the same behaviour in all these softwares. We also tried different PHP versions. It seems to happen more often on source images with a huge dimension/filesize.

            Any idea what to do here?

            I would guess the source image has been truncated for some reason. Perhaps something timed out during the download?

            libvips is normally permissive, meaning that it'll try to give you something, even if the input is damaged. You can make it strict with the fail flag (ie. fail on the first warning).

            Django's runserver command listens on 127.0.0.1 (the loopback interface) by default, since it's meant for development, not production.

            In order for something to be -publishable from a Docker container to the outside world, it needs to listen on 0.0.0.0, i.e. all interfaces.

            Add that to your runserver invocation...

            First off, you should go through a python tutorial. You can start with https://docs.python.org/3/tutorial/index.html.

            You want to run import in a python shell or a python script. Right now, you are running it in a bash terminal, and bash doesn't know what import means.

            Performant method of drawing text onto a png file?
            Asked 2021-Mar-03 at 11:54

            I need to draw a two-dimensional grid of Squares with centered Text on them onto a (transparent) PNG file. The tiles need to have a sufficiently big resolution, so that the text does not get pixaleted to much.

            For testing purposes I create a 2048x2048px 32-bit (transparency) PNG Image with 128x128px tiles like for example that one:

            The problem is I need to do this with reasonable performance. All methods I have tried so far took more than 100ms to complete, while I would need this to be at a max < 10ms. Apart from that I would need the program generating these images to be Cross-Platform and support WebAssembly (but even if you have for example an idea how to do this using posix threads, etc. I would gladly take that as a starting point, too).

            Answered 2021-Mar-03 at 11:54

            I was able to get all of the drawing (creating the grid and the text) down to 4-5ms by:

            • Caching values where possible (Random, StringFormat, Math.Pow)
            • Using ArrayPool for scratch buffer
            • Using the DrawString overload accepting a StringFormat with the following options:
              • Alignment and LineAlignment for centering (in lieu of manually calculating)
              • FormatFlags and Trimming options that disable things like overflow/wrapping since we are just writing small numbers (this had an impact, though negligible)
            • Using a custom Font from the GenericMonospace font family instead of SystemFonts.DefaultFont
              • This shaved off ~15ms
            • Fiddling with various Graphics options, such as TextRenderingHint and SmoothingMode
              • I got varying results so you may want to fiddle some more
            • An array of Color and the ToArgb function to create an int representing the 4x bytes of the pixel's color
            • Using LockBits, (semi-)unsafe code and Span to
              • Fill a buffer representing 1px high and size * countpx wide (the entire image width) with the int representing the ARGB values of the random colors
              • Copy that buffer size times (now representing an entire square in height)
              • Rinse/Repeat
              • unsafe was required to create a Span<> from the locked bit's Scan0 pointer
            • Finally, using GDI/native to draw the text over the graphic

            I was then able to shave a little bit of time off of the actual saving process by using the Image.Save(Stream) overload. I used a FileStream with a custom buffer-size of 16kb (over the default 4kb) which seemed to be the sweet spot. This brought the total end-to-end time down to around 40ms (on my machine).

            Vulnerabilities

            In GraphicsMagick 1.4 snapshot-20181209 Q8, there is a heap-based buffer overflow in the WriteTGAImage function of tga.c, which allows attackers to cause a denial of service via a crafted image file, because the number of rows or columns can exceed the pixel-dimension restrictions of the TGA specification.
            In GraphicsMagick 1.4 snapshot-20190322 Q8, there is a stack-based buffer overflow in the function SVGStartElement of coders/svg.c, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a quoted font family value.
            In GraphicsMagick 1.4 snapshot-20181209 Q8 on 32-bit platforms, there is a heap-based buffer over-read in the ReadBMPImage function of bmp.c, which allows attackers to cause a denial of service via a crafted bmp image file. This only affects GraphicsMagick installations with customized BMP limits.
            An issue was discovered in GraphicsMagick 1.3.26. A NULL pointer dereference vulnerability was found in the function ReadEnhMetaFile in coders/emf.c, which allows attackers to cause a denial of service via a crafted file.
            An issue was discovered in GraphicsMagick 1.3.26. A NULL pointer dereference vulnerability was found in the function ReadCINEONImage in coders/cineon.c, which allows attackers to cause a denial of service via a crafted file.
            An issue was discovered in GraphicsMagick 1.3.26. An allocation failure vulnerability was found in the function ReadTIFFImage in coders/tiff.c, which allows attackers to cause a denial of service via a crafted file, because file size is not properly used to restrict scanline, strip, and tile allocations.
            In GraphicsMagick 1.4 snapshot-20171217 Q8, there is a stack-based buffer over-read in WriteWEBPImage in coders/webp.c, related to an incompatibility with libwebp versions, 0.5.0 and later, that use a different structure type.
