Calculate colour temperature in K

由 余生长醉 提交于 2019-12-01 02:13:29
I have written a lib for working with colours and stuck trying to calculate Tc(k) . From what I have read working in the CIE 1931 XYZ colour space is the way to go and it can be obtained using xyY . So far I have got everything correct to the point of figuring out the correct x and y from : X Y x = ____________ y = ____________ ( X + Y + Z) ( X + Y + Z) The numbers much up to the chart, but cant find anything that details how you go from x and y to Tc(K) eg: For #FF0000 I get the following. x: 0.64007449945677 y: 0.32997051063169 I have read a number of papers on the topic and litterally all

Split image into parts

由 瘦欲@ 提交于 2019-11-30 12:39:50
Is there anything in imagemagick or gimp or other linux compatible tool what can automatically detect individual objects on image and either return some location of object or store each object as separate image? I have image like this one : For other images where objects are located on a grid, I have successfully used crop operator in imagemagick, e.g. for 3x3 grid: convert -crop 3x3@ in-image.jpg out-image-%d.jpg I cannot use crop when there is no rectangular grid, but I thought that white color should be enough for objects separation. It can be done with ImageMagick in multiple steps. The

How to check if program was compiled with debug symbols? [duplicate]

This question already has an answer here: How can I tell if a library was compiled with -g? 7 answers I'd like to trace some code in GIMP and therefore need GIMP with debug symbols enabled. I don't remember whether I have enabled them during compilation. How to check that without recompiling the program? You can use file and objdump on Linux. In particular, you can look at whether file says "stripped" or "not stripped", and whether objdump --syms outputs anything useful (for me, it says "no symbols" for a regular build). When running the objdump --syms command, I see much more than " no

How to extract text from a PSD file?

由 我的未来我决定 提交于 2019-11-29 16:41:26
问题 I need to extract the text from the layers in a photoshop PSD file on linux. Does anyone know how to do that? Gimp rasterizes the text and you can't copy and paste it. Also, note that I do not own the Photoshop program. 回答1: Have you tried using vim? VIM comes with a flag that lets you edit a binary file. I tried editing a PSD file with: vim -b file.psd This is an example of what I got when editing the file: <dict> <key>com.apple.print.PageFormat.PMAdjustedPageRect</key> <array> <real>0.0<

Read SVG file with Python/PIL

问题 I'm new to Python so please be patient with me. Basically my script should run like this: 1) Load an image and split it into R, G, B channels 2) Mark an area of that image with an existing path saved as a svg file and 3) perform some calculations with the R,G,B values of this area. (further send the the image either to folder A or B, depending on the outcome of the calc) I've done 1) and parts of 3) but my current problem is to load the svg file and apply it on my image. The image is a
