PDFfiller is full featured and extremely easy to use. You can add text, images, highlights and shapes with just a few clicks, and position what you add exactly where you want it to be. Who could ask for more from a PDF product? I mean, try doing those things with Adobe Acrobat and you'll quickly see how much easier it is to do with PDFfiller.

All PDF tools in one app My overall satisfaction about that app is a lot, it's just great tool for everyone, for students and also employees as well, at any time people can make change in their document and send it wherever it's needed. That's basically great app, because you can solve all document issues in one app, scanning, adding image to the document putting dates, even signature, saving as pdf, or word or excel, sending to email, printing and etc. which help users to save more time. I remember I faced problem while logging in, actually I think to login for that kind of program is something extra.

Excellent application but not sure if… Excellent application but not sure if its worth $9 a month for an individual user working on domestic household forms. Definitely worth it if using for a small business.

I'm a layman when it comes to figuring out things. I'm a layman when it comes to figuring how do create things on the Internet. It's always cool when I can chat with someone who can figure out what I'm trying to do and have the patience, at least I think they have the patience when I'm going round and round with them on each step in getting my dilemma resolved. As before in chatting with someone at the chat desk, they have always been professional.

Choose File > Import > Image Sequence... and navigate to the Albedo folder. Select the first image in the sequence and then click the Open button. Specify the Sequence Options. Use all twelve slices, beginning with the first slice and incrementing by one. Do not scale the images.
Align the images Basically you just need to check a few settings then click on some bright stars in the image and Image does the rest. The details: In your image sequence, click on the align button and read the instructions that pop up. Click on a few stars, right click when done to start the alignment process.
Combining stacks Just open each image stack separately, then run Image > Stack > Merge Channels..., assigning each image stack to the desired channel. The result will be a composite of each respective plane.
Hold the alt key down when moving or resizing to force the location and size to be displayed in pixels. With Image 1.42 and later, hold the control key down (command key on Macs) to resize around the center. With Image 1.43 and later, hold the alt down to constrain resizing to the current aspect ratio.
Open your 3 images for the 3 channels in Photoshop. Copy two of them into the third — select all (CTRL+A in windows) and copy (CTRL+C) and paste it (CTRL+V) into the other file. Now you will have your 3 channels as layers.
In Photoshop, choose File > New. ... Drag an image from your computer into the document. ... Drag more images into the document. ... Drag a layer up or down in the Layers panel to move an image in front of or behind another image. Click the eye icon to hide a layer.
