Adobe Interactive Forms performance: logo/image optimization
Chris Scott has kindly listed the general approaches to Adobe Interactive Forms performance optimization in his post. As it’s mentioned in the post the main bottleneck is often ADS renedring. I’m going to tell about one possible way of ADS rendering and Data transmission time optimization. It was really helpful for me when I was developing Adobe forms for automotive business.
The customers have often strict requirements on the output forms layout and on the logos/images printed on the forms. There logos are part of the companies’ brandbooks and have requirements on the colors, density, image quality and image proportions. As result the form developers must often use heavy true color images which increase form size and the time of ADS rendering and Form transmission from the ADS server to the client’s PC.
As result the developers must be careful while using images on the forms. The images are the first things to be checked during Adobe forms performance optimization. Even a small pixel size logo can blow your form up making it considerably bigger. As result the user will wait for a long time till the form appears on the screen/printed on the printer.
You must check your image file size and optimize the image if it’s big enough compared to the PDF form size.
First thing to be done is to convert the images to a proper image format. It should be JPG or PNG files, the uncompressed bitmaps (BMP) must be avoided. Personally I prefer to use JPG because it’s usually smaller and the format provides more possibilities for optimization/size reduction.
The second step is to minimize the image pixel size. It must be so small as needed for the form image size. There enough free or standard Windows tools providing such functionality. Even Windows Paint application can do this.
After the logos are converted to JPG you should to optimize your image. There are several online JPEG compressor services available (JPEGmini, TinyJPG, etc.). They are free and intuitive easy to use. You have to upload your JPG file onto the online compressor and download the compressed file. The images are usually compressed saving 40%-70% of their original size with no quality loses! As result you can decrease your form size and the form generation time considerably.
Hope this small tip will be helpful for your performance optimization.
