digiuno totale di php
salve mi chiamo angelo dovrei riuscire ad inserire un template iptc all'interno in un immagine; copiare l'immagine ridefinita (ridotta) in un altra cartella
ho trovato degli script in php uno per inserire dei dati iptc
in un immagine l'altro per copiarla e ridefinirla:
iptc embedding:
....................................
array iptcembed ( string iptcdata, string jpeg_file_name [, int spool])
.............................................
imagecopyresampled
(PHP 4 >= 4.0.6)
imagecopyresampled -- Copy and resize part of an image with resampling
Description
int imagecopyresampled ( resource dst_im, resource src_im, int dstX, int dstY, int srcX, int srcY, int dstW, int dstH, int srcW, int srcH)
imagecopyresampled() copies a rectangular portion of one image to another image, smoothly interpolating pixel values so that, in particular, reducing the size of an image still retains a great deal of clarity. Dst_im is the destination image, src_im is the source image identifier. If the source and destination coordinates and width and heights differ, appropriate stretching or shrinking of the image fragment will be performed. The coordinates refer to the upper left corner. This function can be used to copy regions within the same image (if dst_im is the same as src_im) but if the regions overlap the results will be unpredictable.
Note: There is a problem due to palette image limitations (255+1 colors). Resampling or filtering an image commonly needs more colors than 255, a kind of approximation is used to calculate the new resampled pixel and its color. With a palette image we try to allocate a new color, if that failed, we choose the closest (in theory) computed color. This is not always the closest visual color. That may produce a weird result, like blank (or visually blank) images. To skip this problem, please use a truecolor image as a destination image, such as one created by imagecreatetruecolor().
Note: imagecopyresampled() requires GD 2.0.l or greater.
