COLDFUSION CONVERT TIFF TO PDF

Finally, ColdFusion 8 has incorporated image manipulation directly into the ColdFusion tag and scripting language. These products, while excellent in quality, just meant adding one more level of complexity to any application that required server-side image manipulation. Now, with CFImage and an abundance of image related functions, ColdFusion has done to image manipulation what it has done to most every other aspect of web applications development - it has made it simple. Due to the wide array of image functionality in ColdFusion 8, I am going to try and break this tutorial up into several small and management parts. The first part will cover basic reading and writing of images using CFImage and the related image manipulation functions. But, before we get into that, let's just quickly touch upon these new features as a whole.

This isn't the end of the series - just the last post I'll be writing about the tag. After this we move on to PDFs and Forms which should be pretty darn exciting as well. This UDF used the feature that I'll be discussing today. Let's start by talking about how the thumbnails work. ColdFusion provides you with the following main options for thumbnails:.

Along with these options, you have a few other settings as well I'll discuss later. Let's look at a simple example:. Ajax UI controls make my design suck less. That's like Not that CF developers make mistakes.

And that's saying a lot. Yeah, I said Interfaces. Server Monitor - and it's all Flex. Most of the code isn't terribly relevant to thumbnails. I start off creating a thumbs folder if it doesn't exist.

Then a PDF document variable is created. Go ahead. I'm going to make a tee shirt I think. The critical line is the last one. The source is the PDF I created in memory earlier. I used a high resolution and a scale of 50 and lastly set overwrite to true. That generated this graphic note I cropped the image a bit :.

Let me point out something. Where did this name come from? ColdFusion automatically uses a name of the format:. You can overwrite the prefix by suppling the imagePrefix attribute.

If you leave imagePrefix blank, it defaults to thumbnail, unless your source is a PDF file. In that case the filename is used instead. Consider this modification to the previous example:. So what's cool about this? You can provide image previews of PDFs before users download them. As an example:. Raymond is a developer advocate.

You can even buy me a coffee! This is a bit surprising since most other image related options give you more finer control, but hey, sometimes simpler is better.

You can specify which page to generate thumbnails from. My getThumbnails UDF simply used the first page. That generated this graphic note I cropped the image a bit : Let me point out something. Raymond Camden's Picture.

This data is usually written at the time that the image is created, usually by the camera or scanner. Here we will show how all the supported EXIF tags can be read and also demonstrate how some tag values can be converted into meaningful values. The code shown below will display the name of each EXIF tag stored in the file, together with its value. Instead it stores all the values in an array and they can be read by index or by the tag name. In this example they are read by index by finding the total number of tags present and then looping through them.
