由 只谈情不闲聊 提交于 2019-12-24 07:59:49

问题 I wish to display images in a tcltk window (not in a R device) using R but the simpliest method (below) supports only GIF files : require(tcltk) tcl("image","create","photo", "imageID", file="a.gif") w <- tktoplevel() l <- ttklabel(w, image="imageID", compound="image") tkpack(l) and I my files are png/jpeg (file containing histograms generated by my program itself) someone has an idea to do that conversion ? thank you 回答1: Despite the warnings this seems to succeed: png("test.png") plot(1,1)

GIFs changing randomly

由 旧时模样 提交于 2019-12-24 03:04:49
问题 I got a problem with GIFs and Javascript. I got different GIF-animations which are all the same format and I want them to change randomly after they are played one time. I tried to solve this with Javascript but I only could make it work with an exact time to make the change and not when each GIF-animation is finished (they are all finishing at different times). <html> <head> <script type="text/javascript"> <!-- var ima = []; ima[0] = 'bilder/bild1.gif'; ima[1] = 'bilder/bild2.gif'; ima[2] =

How to fix .gif with corrupted alpha channel (stuck pixels) collected with Graphicsmagick?

由 孤街醉人 提交于 2019-12-24 01:57:15
问题 I want to convert an .avi with alpha channel into a .gif.

Then, I use gm convert -loop 0 frames/ffout*.png output.gif to collect a .gif. But it seems that pixels of the output.gif just get stuck when something opaque is rendered on top of the transparent areas. Here's an example: As you can see the hearts and explosions do not get derendered.
