For example IrfanView needs 0.9 s (874 milliseconds) to load and show this image! (Rotating: 14 s, Saving 4 s) Today I am here on a Window system (Dektop PC with 3 GHz). I think this depends on the cleverness and the algorithms of the programm. But when read in and decompressed it goes to 12,000 x 9,000 x4(channels rgba) = 432 MBytes It took minutes to even open in Mac PREVIEW and GraphicConverter for me. And then takes quite some time to write the image.įmw42 wrote:You file is a compressed PNG of size 540 KBytes. If you watch, you will see the monitor show that it stops at times to write to disk as it read and decompresses the image. So your whole image would barely fit and not allow any room for other code for processing. This is on my G4 Mac Mini PowerPC (one processor) OSX Tiger with only 512 MBytes of memory. Time convert -monitor flat.png -quality 25 flat_tst1.jpg You can see how it progresses by adding -monitor to your command and time it by using time. You need to recompress the output before saving. However, I will defer to the IM developers to explain in more detail or correct me.Īlso much of the time is spent reading and writing the output, especially the output as it is now writing 432 MBytes. This is a memory issue and depends upon your system and IM how much memory it allows you to use before paging to disk (as I understand it). It took minutes to even open in Mac PREVIEW and GraphicConverter for me. But when read in and decompressed it goes to 12,000 x 9,000 x4(channels rgba) = 432 MBytes For example, what does one do if ImageMagick fails to configure or compile? Or what if you want to install ImageMagick in a place other than the ImageMagick-6.?.?/VisualMagick/bin folder? You will find the answer to these questions, and more, in Advanced Windows Source Installation.You file is a compressed PNG of size 540 KBytes. The above instructions will satisfy a great number of ImageMagick users, but we suspect a few will have additional questions or problems to consider. To verify ImageMagick is working properly, launch a MS-DOS Command Prompt window and typeĬongratulations, you have a working ImageMagick distribution under Windows and you are ready to use ImageMagick to convert, compose, or edit your images or perhaps you'll want to use one of the Application Program Interfaces for C, C++, Perl, and others. Finally, choose Build->Build Solution to compile and build the ImageMagick distribution. Choose Open->Project and select the VisualStaticMT workspace from the ImageMagick-6.?.?/VisualMagick/ folder. The configuration utility just created a workspace required to build ImageMagick from source. Now press, on Next twice and finally Finish. If you are using the Visual Studio 6.0 IDE, make sure no check is next to the Generate Visual Studio 7 format option. Press Next and click on the multi-threaded static build. To compile the program and on completion run the program. Select the configure workspace from the ImageMagick-6.?.?/VisualMagick/configure folder and press Open. Next, launch your Visual Studio IDE and choose Open->Project. You can unpack the distribution with WinZip or type the following from any MS-DOS Command Prompt window: If you don't have a compiler you can still install a self-installing binary release.ĭownload ImageMagick-windows.zip from or its mirrors. Users have reported success with the Borland C++ compiler as well. For example, what does one do if ImageMagick fails to configure or compile? Or what if you don't have administrator privileges and what if you don't want to install ImageMagick in the default /./usr/local folder? You will find the answer to these questions, and more, in Advanced Unix Source Installation.īuilding ImageMagick source for Windows requires a modern version of Microsoft Visual Studio IDE. To install, typeįinally, verify the ImageMagick install worked properly, typeĬongratulations, you have a working ImageMagick distribution and you are ready to use ImageMagick to convert, compose, or edit your images or perhaps you'll want to use one of the Application Program Interfaces for C, C++, Perl, and others. Administrator privileges are required to install. If ImageMagick configured and compiled without complaint, you are ready to install it on your system. Download from or its mirrors and unpack it with this command: A compiler is required and fortunately almost all modern Unix systems have one. ImageMagick builds on a variety of Unix and Unix-like operating systems including Linux, Solaris, FreeBSD, Mac OS X, and others.
