IrfanView
Introduction
The IrfanView Web site is: http://www.irfanview.com/english.htm. IrfanView is a very fast FREEWARE (for non-commercial use) 32-Bit graphic viewer for Windows 9x/ME, WinNT, Win2000 and Windows XP.
Note: Be careful, during installation it tries to install Google Toolbar for Internet Explorer and Google Desktop Search. Be sure to uncheck these during installation
IrfanView supports opening and saving files in an amazing array of file formats, literally almost ANY format!
Pros:
- Small in size. Only 884kb.
- Screen Capture with mouse cursor in the capture area
- Many graphic formats supported including transparent background for GIF and PNG.
- Saves to GIF and PNG without degrading the colors unlike MS Paint.
- Crop, resize, rotate, and zoom functions.
- Add background transparency to GIFs and PNGs.
- Has a JPG optimization feature when saving.
Cons:
- No painting tools such as line drawing, paint fill, etc.
- Does not have preview for JPG optimization.
How to Shrink an Image file using Irfan View:
- Load the IrfanView program
- Click on "File" then "Open" and then locate the image that needs to be Compressed and then click the "Open" button.
- Click on "Image" and then "Information" and look to see the "Current size". This might be displayed as something like 900 x 675 Pixels for example, which would mean the image is 900 pixels wide and 675 pixels high. Close the dialog box by clicking "OK".
- If the image is wider than 500 pixels (it probably will be), do the following - Click on "Image" then "Resize/Resample..." and then type in a width of "500". You will see the height automatically adjusted to preserve the image proportions. (Make sure the "preserve aspect ratio" button remains ticked or the image will become distorted.)
- Click "OK" and the image will be adjusted to have a width of 500 (well done!).
- Next, Click on "File" and then "Save As.." and type in a new and unique file name (must be unique name to avoid over-writing the original file or any other file!) and select the file type (JPG - JPEG FILES) - Once the JPG file format is selected, you will see the following box appear.
Set the "save quality" slider somewhere between 70 and 80 and click on "Save" and the job is complete.
Features:
- on the toolbar, the info icon, returns all the stats on the current image, including resolution.
- If the image is an original image from a digital camera, the information window will have a button at the bottom to click for "Additional info" which will display the EXIF information for the image. EXIF, Exchangeable Image File, is a standard digital image file format that includes additional information such as date and time photo was taken, camera make and model, f-stop and shutter speed, ISO (effective camera speed), horizontal and vertical dimensions in pixels, whether or not the flash fired, etc.
- Blue arrows on the toolbar are useful to page you through the different images in the same directory as the File you have Opened.
- Zoom icons are useful for images that may not fit within a fullscreen window.
- Click and drag within the image and then the crop function is in the Edit menu, Edit | Crop
- Edit menu Cut function will also let you Cut out the selection or Cut away everything EXCEPT the selection.
- all other image editing functions you're likely to want, such as Resize, Rotate, and Enhance Colors, are in the Image menu.
- File | Batch Conversion/Rename will let you convert a number of files all at once (like from TIF to JPG). You can even use the Advanced Options and also apply any of the edits in the Image menu at the same time (the same edits to all images, like resizing to thumbnails).
Some Tips:
- When you have an image open in the main window, double clicking it will open it in full screen mode. Use the space bar and backspace to move through other images in the directory. ESC will return you to the main window.
- You can scroll through a large image faster by holding down the right mouse button and moving the mouse. You will see a hand image replace the normal cursor. Move the hand up or down, or side to side to move the image. Also, the Page Down and Page Up keys will scroll through an image that is larger than the screen.
- When scanning a black and white image, you'll get better results by scanning it as color, at a good resolution, then using IrfanView to convert to grayscale.
- Enlarging an image: for best results, use Resample, then Sharpen. For an image of decent resolution, this will make an enlarged version with no loss of quality. If the large version is not good enough, Reopen the image (without saving anything.) A fresh copy will be loaded. Try the resampling again, but use a different filter.
- Be careful with "multiple instances" of IrfanView. It is possible to highlight a long list of associated filenames in a directory, then accidentally double-click them. In this case, IrfanView will try to load itself as many times as there are images!
