![]() What I would really like is a user-controllable scrub/scroll bar so the time-lapse can be changed to any time period. all browsers can), or if I should go the route of HTML5 video. Now I have to figure out whether an animated gif is appropriate for me (pretty universal readability. It can reduce the animated GIF file size by 3050 at the cost of some dithering/noise. 100 years worth (iow, 100 frames) of a few hundred thousand to a couple of million cells. GIF compressor optimizes GIFs using Gifsicle and Lossy GIF encoder, which implements lossy LZW compression. This would make a significant difference when I work with real data. Oh, and GD is about an order of magnitude faster than Imager. ![]() Silly me, of course, I was doing it wrong. You should also check that each frame, when viewed as a discrete image, actually displays what you think you are drawing in that frame.Īnd finally, you need to ensure that all the colors you use in the frames, are added to the palette of the base image, before you capture the header with gifanimbegin() That is, you appear to be drawing a complete set of moving rectangles into each frame, rather than one rectangle at a different position in each frame. That doesn't affect a complete fix though because you're also confusing what constitutes a frame and what a complete animation. You should be printing the accumulated headers and frame data to the file: print F $gifdata = $frame->gifanimadd, but then you print just the header info from the image into the file: print F $img->gif(). $img->filledRectangle($xmin, $ymin, $xmax, $ymax, $color) īut am still curious as to why GD doesn't work for me.įirst, you are accumulating the frames in $gifdata. My $xmax = ($x1 * $cell_width) + $cell_width My $ymax = ($y1 * $cell_height) + $cell_height My $num_of_cells_in_y = ($img_height / $cell_height) - 1 My ($img, $img_width, $img_height, $cell_width, $cell_height, $col +ors) = $num_of_cells_in_x = ($img_width / $cell_width) - 1 Project description Python package wrapping the gifsicle library for editing and optimizing gifs.
