  • Circular Thumbnails with ColdFusion / CSS
    Thumbnails were always square, at least in my applications. But thumbnail images in different shapes popping up here and there nowadays, I decided to give that a try too. It is quite easy and looks quite elegant. This can be done with CSS alone or with few line of CFM. Here is my large image and I created a face recognized traditional square thumbnail using ColdFusion. (more..)

  • Face Cropped Thumbnails with ColdFusion
    Yesterday I played around face recognition in ColdFusion with Jviolajones and it did a good job detecting faces off an image and providing with the coordinates. The final goal of this exercise is to create thumbnails of images focusing on faces, if there are any to be found in the image. Here is my sample image. There are two faces on them. First I want to bring them into a single frame. I would like to include all the faces into the final thumbnail if possible. (more..)

  • Face Detection with ColdFusion and Jviolajones
    I was trying to do face detection with ColdFusion and JJIL Java library last week. Today I gave Jviolajones library a stab and it turn out quite well. It misses some faces, occasionally returns false positive results, but overall it did pretty good job. My final goal is to create thumbnails of image cropped around faces, not rather crucial face detection. Jviolajones seems to be a good candidate for that. (more..)

  • Face Detection with JJIL Library and ColdFusion (Experiment)
    I was trying to do face detection with Faint Java library and noticed quite disappointingly it only works with 32bit processers. Looking elsewhere found the JLIL Java library build to do face detection in mobile applications and also quite a nice blog post by Richard Nichols. It was a good start. I suggest you to read that post first since I build a new copy of JJILCore.jar with Richard's updated codes. (more..)

  • Image Trim with ColdFusion
    I was working on QR barcode using Zxing and the barcode generated by Zxing tend to give extra white spaces on some barcodes but my designer wanted trimmed image without extra white space around. ColdFusion does not have an image trim function, so I put together a small function to trim background of an image. This function takes two arguments. Image (required) This can take ColdFusion image object or path to an image file. (more..)

  • Draw HTML with ColdFusion ImageDrawText() function
    ColdFusion image text writing functions are relatively simple. It can write text on an image quite fast with some styles, but it’s not capable of go to the next line or handle text styled with multiple fonts. There is lot more space left for draw text function to be improved. Last week I had to convert html formatted string of text to an image and ColdFusion native image functions could not do that.
