Is it possible with PHP GD to skew/distort images on both sides ?
I already check other question/solution but I really don't understand how to move all the corners of the image.
What I need is transform a flat image to a distort image moving all 4 corners, something like if you use Adobe Photoshop transform distortion function that allows to move single corner to a new position.
Is it possible ?
Many thanks in advance.

It can be done with the help of the QB extension.
In theory, it's possible to accomplish the same thing using just the built-in GD functions. It'd be agonizingly slow though.
I am going to create some images with text using PHP script and want to simplify the process.
Are there any classes/libraries/wrappers for GD and ImageMagick that can help me with this? For example, add some effects, custom fonts, etc.?
This will help you : http://php.net/manual/en/book.image.php
imageloadfont function can be used to load new fonts refer : http://www.php.net/manual/en/function.imageloadfont.php
You could look into using SVG for this. Text items and effects such as blur can be added very easily with simple XML manipulation, and then you could render it with inkscape - in PNG or PDF format.
I want to overlay two PDF file in same page. I want to use one PDF as background and overlay other PDF data on this. I do not want to concat the two PDFs.
tcppdf definately doesn't support this idea, I'm not even sure if it supports background images? What you could do is covert the pdfs into images, do some image manipulation to make one the background of the other, then convert back to pdf?
I know this sounds messy but the less work done with the pdf generation the better in my experience.
I have a text files which I'm trying to convert into images. I know how to do this with GD but I'm having trouble finding suitable functions with imagick/imagemagick.
you want annotateImage() there will be more than that you need to do like setFont() ,setTextAlignment() etc... but that should get you going
I have been reading about this but I have to do some thing. I have a table with diagonal text in the heading columns and horizontal text in the rows. I was able to make text diagonal using CSS rotation thing, table data is coming from db and I want to generate the same html into the pdf. I don't know who to write diagonal text in the pdf. The solution is to create an image of the visible html table with data and then store it and then make pdf and embed that image there. I have been reading the GD library but how can I make table in GD library I am stuck , Stack Overflow is the last resort. Please help.
try this ezpdf class http://www.ros.co.nz/pdf/readme.pdf. they got some sample code to rotate text and how to embed image into pdf.
example
for ($angle=0;$angle<360;$angle=$angle+20){
$r=rand(0,100)/100;
$g=rand(0,100)/100;
$b=rand(0,100)/100;
$pdf->setColor($r,$g,$b);
$pdf->addText(300+cos(deg2rad($angle))*40,300-
sin(deg2rad($angle))*40,20,$demotext,$angle);
{
$pdf->stream();
If you want to go directly from your HTML code to PDF, and if you need something entirely in PHP you can try dompdf. The 0.6.0 release will include CSS transform support.
For image generation in PHP you can use GD functions (fast) or iMagick (not so wide spread, docs are WorkInProgress, but you could do almost anything you can imagine with it).
GD should be enough.
A simple idea about making text diagonal would be to just rotate the image, once you output text from the db onto it.
Use wkhtmltoimage or wkhtmltopdf.
Do you need to do this only once or does this need to be an ondemand service? If not why not just load the html page take a screenshot and crop it down to the table?
Instead of trying to convert HTML directly to a PDF document, you might want to try a PDF library for creating the document directly in PHP. This way you will get more control over what the PDF looks like, and it may be a better solution that trying to convert your HTML output.
