png

问题 I have searched everywhere to find a possible solution to my problem. Unfortunately I cannot seem to figure it out. I have a .php file that creates an image based on other images. I had the script working exactly as it is right now before without flaws. But after fiddling around with some other files it suddenly stopped working and is generating corrupt .png images now on Firefox, Chrome and IE. image.php <?php ini_set("display_errors", 1); ini_set("error_reporting", 2047); ini_set("display

问题 Links on my website: http://rnmtest.co.uk/oddfellows/ If you hit 'Dine' you should see a 'Book Now' button. This element is not clickable in IE. The area below it has a semi-transparent png as the background. The content is loaded via jQuery. I have put the anchor within a container div as recommended by other websites, but this has had no effect. If I resize the window in IE8 I can sometime click a small portion of the button. This effect occurs on all anchors, not just the images. 回答1: This

问题 I generate a video from png images using ffmpeg -i visualization/%d.png -c:v libx264 -vf "scale=500:trunc(ow/a/2)*2" -pix_fmt yuv420p z.mov and if images have transparencies, they become black. Can I somehow make them white? 回答1: Before running ffmpeg, use ImageMagick to "flatten" each PNG against white. mogrify -background white -flatten visualization/*.png 来源： https://stackoverflow.com/questions/21723343/specify-background-colour-when-generating-movie-from-images

问题 I am trying to save images in Matlab by using the print function: myImage = magic(500); myFigure = figure('visible','off'); r = 1; set(myFigure, 'PaperUnits', 'inches', 'PaperPosition', [0 0 1920 1080]/r); % the program works fine on both computers without the line above % however, the program runs fine on one computer only with this line imagesc(myImage); axis image; print(myFigure, '-dpng', sprintf('-r%d',r), 'myOutput.png'); When I run this program locally with Matlab R2012b, it works as

问题 When firefox (3.0.6) renders a png image at certain widths (e.g., 50%), a thin grey line is shown along the left and top edges of the content box. The line disappears at other widths (e.g., 70%). Furthermore, the line doesn't seem to be present in the original image (using gimp to inspect the image). The phenomenon occurs in the absence of the CSS style markup -- in the HTML example below, the CSS is present to clarify where the grey lines are located -- it seems clear that the grey lines are

问题 I'm currently designing Pac Man in java using swing. I have PNG images that are drawn on screen using the following statement. wall = new ImageIcon(GamePanel.class.getResource("wall.png")).getImage(); g2d.drawImage(wall, x, y, this); The problem I'm having is that it seems to render a very low colour depth rendition of the actual file. It seems like it does retain transparency (grey background is the Panel bg color), but it loses color depth. The actual image looks like this: When running, it

问题 So, I'm using CSS3 in order to create sidebar boxes in my site design, this works nice and dandy. Using http://css3pie.com in order to create the effect in IE. Again, nice and dandy. Now, comes my issue - For each relatively positioned module, there is an absolutely positioned icon within it, that is set to being top: -20px in order to give it a pop-out effect. Obviously this doesn't work in IE6, as well it doesn't play nice with any PNG fix codes. However, for IE6 users I can switch to a low
