I really like it so far. The snap to grid text editing is fantastic. The cloud options and email sync are perfect. Nice job. The UI is almost exactly like my Neat scanner software so it's very intuitive.

My wife had some US Government forms that needed to be filled out and returned. Because of her medical condition, she couldn't fill them out longhand, and she asked me if there was a way she could type and fill them in. We couldn't find access to a typewriter (WHAT'S THAT???), but I searched on Google and found information about your app. I had worked with some PC-based forms applications before, so I knew what type of function I was looking for. I scanned the forms into a PDF, and PDFfiller opened the files and allowed me to create editable fields on the forms which she then filled using your browser-based app. It got the job done! There were a couple times where she thought she had lost everything, but because of the automatic save function, nothing was lost. Unfortunately, I don't have any other immediate need for this, but I certainly hope you use this for promoting your product. I would have given it 5 stars had there been an apparent way of copying all the fields I added to one page and paste them onto identical subsequent pages in my document (you know the Government--lots of duplicate type information!). I had to create the same fields over about 8 or 9 identical pages on one of the forms. If I find I do have more use for this app in the near future, I will purchase it!

cool but needs a more user friendly interface. like small pdf for example. An easy converter option, with a file compress option would be cool. But as far as functionality and edit ability, PDF filler produces superior edits and is why I choose it over other products.

Adobe should take notes from PDFFILLER
I like that it's web based which allows me to use it on any computer without having special software installed.
Nothing too bad but sometimes the converter feature would hang when I was converting large documents.

What is resolution in image processing?
Image resolution is the detail an image holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved.
What is image size?
Image Size is the term given to describe the height and width of an image in pixels. Maximum Image Size is determined by the megapixels of a given camera — for example, a 10-megapixel camera will give a maximum image size of 2592 by 3872 pixels.
What is the size of a high resolution image?
Count your pixels Hi-res images are at least 300 pixels per inch (PPI). This resolution makes for good print quality, and is pretty much a requirement for anything that you want hard copies of, especially to represent your brand or other important printed materials.
What is pixel size of an image?
The physical size of an image refers to the dimensions in which it would print (ex: 8.5" x 11") or the pixels dimensions of an image displayed on the web (ex: 600 pixels x 800 pixels).
What is spatial resolution in image processing?
Spatial resolution is a measure of the smallest object that can be resolved by the sensor, or the ground area imaged for the instantaneous field of view (IFO) of the sensor, or the linear dimension on the ground represented by each pixel. From: Advanced Remote Sensing, 2012.
How do you find the spatial resolution of an image?
The size of the area viewed is determined by multiplying the IFO by the distance from the ground to the sensor (C). This area on the ground is called the resolution cell and determines a sensor's maximum spatial resolution.
What is mean by spatial resolution in mapping?
A measure of the accuracy or detail of a graphic display, expressed as dots per inch, pixels per line, lines per millimeter, etc. ... Resolution is the accuracy at which a given map scale can depict the location and shape of map features; the larger the map scale, the higher the possible resolution.
What is spatial information in image processing?
Answered Nov 4, 2017. The term spatial refers to the space. The spatial domain is the normal image space, where some magnitude is allotted to different positions (x, y). A digital image is a grid of pixels. A pixel is the smallest element in an image.
Why is image resolution important?
Size and resolution of images are inversely proportional to each other. Scaling images up in a layout program will decrease the output resolution of the image at the same percentage of the scale. Optimal image resolution for printing is 300 dpi.
