问题 I have made a script which renders an image from a string. It is fine apart from the fact that apostrophes do not show. A space is where the apostrophe should be. Any ideas? Here is the rendering code: (the string is just normal text. Like a newspaper article) $text = $_SESSION['article']; $arrText=explode("\n",wordwrap($text,69,"\n"));//change number 75 here to check the wordwrap $im = @imagecreate(650,2500); //creates an image (width,height) $background_color = imagecolorallocate($im, 0, 0,

问题 Just for the record - my first question here but hopefully not my last input in the community. But that's not why I'm here. I'm currently developing a simple system that has to generate an image with a text on it. Everthing went well until I realised that GD cannot handle UTF-8 characters like ā, č, ž, ä, ø, é and so on. To clear things up - I'm using imagettftext() Trying to solve my problem I dug into depths of google and some solutions were returned, none of them, sadly, solved my problem

问题 I've got the following function that generates and saves an image based a text parameter. How can I call this in my file? I tried INCLUDE 'outPrice.php'; to link to the external PHP and called it with this command, outPrice($text); To which I got the following response. Warning: Cannot modify header information - headers already sent Any help would be appreciated. function outPrice($textval){ $textcolor = '666666'; $font="bgtbt.ttf"; $size = 20; $padding= 1; $bgcolor= "ffffff"; $transparent =

问题 Below is my resize.php script. I needed to install the GD Library and did so but I am still having trouble gettint the image to process like it used to my old server.HERE You can see with the error reporting on there is an empty image created and the following errors display: Warning: getimagesize(http://stackoverflow.com/questions/19817599/../wp-content/themes/Explorable/panos/Pano__0000.jpg): failed to open stream: HTTP request failed!

问题 I had an image upload script that worked on my little shared hosting, but just as I switched to Virt Ded, it immediately stopped working. After some research I determined the culprit to be the PHP function imagejpeg() - which was the last bit of code in the script. It allows me to specify null as the filepath (in which case it prints it to the screen), but does not allow me to enter ANY filepath without return false. Anybody know what is going on? 回答1: First I would see if the PHP install

问题 I am using GD library in my Perl script that allows me to draw a true-type-font text. Because I don't know exact size at the beginning, I set my $i = new GD::Image(3000, 3000); and then I draw my text my $black = $i->colorAllocate(0, 0, 0); my @b = $i->stringFT($black, './ttf/cour.ttf', 12, 0, 0, 0, "\n$text"); where @b contains my crop data. I wish to execute something like this (incorrect syntax): $i->crop(0, 0, $b[2], $b[3]); ...but there is no such crop function available. How can I crop

问题 I'm working on a very large number of images. I have to create four JPEG versions of each image: original size JPEG 700x430 version 57x57 thumbnail 167xN thumbnail (variable height, maintain aspect ratio) I used the following two helper functions: function thumbFixed($srcfile, $dstfile, $dstWidth, $dstHeight) { $srcImg = imagecreatefromstring(file_get_contents($srcfile)); list($srcWidth, $srcHeight) = getimagesize($srcfile); $srcAR = $srcWidth / $srcHeight; $dstAR = $dstWidth / $dstHeight;

问题 I've been seeking for JPG saving library for long time for c++, but i cant seem to get anything to work. Now i am trying use LibGD: What im doing wrong ? It seems to work, but the saving crashes. Code: ... #pragma comment(lib, "bgd.lib") #include <gd/gd.h> ... void save_test(){ gdImagePtr im; FILE *jpegout; int black; int white; im = gdImageCreateTrueColor(64, 64); black = gdImageColorAllocate(im, 0, 0, 0); white = gdImageColorAllocate(im, 255, 255, 255); gdImageLine(im, 0, 0, 63, 63, white);

问题 I have a PHP script that converts true color images to palette images if the number of different colors in the image is less than or equal to 256. In my test case, I have an image that contains 79 colors. After running ImageTrueColorToPalette on it without dither and the $ncolors parameter set to 79, I have an image that only has 15 colors in it. I have even tried running ImageColorMatch on it after converting it to palette, and I still end up with only 15 colors. Using GD in PHP, how can I
