The Image Window

Below is an example of an image window, with the original image on the left side and one visible variation:

For each image there is the file size displayed that the image will need when saved. As you can see the right picture is greatly reduced in image size (approx. 4.4 KBytes compared to 114 KBytes). The left image is a BMP file with 24 bits per pixel, which means that the image can contain up to 16 Mio. unique colors. The right image is a JPEG file with medium compression ratio (200 on the WebGraphics Optimzier scale from 2 - 256). As you can see the size of the compressed image is only 4% as big as the original image, and it has in 1.4 second download time on internet compared to 35.8 seconds for the original image.

You can display up to five variations and select different file formats or compression ratios to compare the image file sizes. The Intellioptimize feature helps you to find the best compression settings.

When you click on the right mouse button on one of the images, a pop-up menu will be displayed containing a context sensitive selection of commands.

Depending on which image you have selected (original or variation, appears with a red title) you can chosse between different image operations:

Special


Resize
Original Tools: Resize

Tools for resizing and cropping images:

Resize Image

Changes the width and height of an image.

Width

The new width of the image in pixels. If the maintain aspect ratio box is checked, the height of the image will be changed accordingly.

Height

The new height of the image in pixels. If the maintain aspect ratio box is checked, then the width of the image will be changed accordingly.

Maintain aspect ratio

If checked, the aspect ratio of the image will not be changed when resizing the image

Resample Image

If not checked, the image will be resized using the normal resizing function.

If checked: Resizes the bitmap, using interpolation and averaging to produce a higher-quality image that would be achieved by normal resizing.

Crop image

Trims the image to a specified size.

There are two ways to crop an image:

1. 	By pressing the Apply button: The image will be cropped using the given settings

1. 	By pressing the Crop selection button: The selected region is trimmed.

Direction

The direction of trimming the image.

Width

The Width of the image after trimming it.

Height

The Height of the image after trimming it.

Crop selection

Trims the selected region. Works only if a region selection is defined.


Adjust Color / Intensity
Original Tools: Adjust Color / Intensity

Contains image manipulation functions that concern the color and intensity of the image.

Brightness

Changes the brightness of the image from -100 to +100 percent.

Gamma Correction

Adjusts the intensity of colors in the bitmap by changing the gamma constant that is used to map the brightness values.

Intensity values ideally follow a logarithmic progression, because the eye perceives changes in intensity as being equal when the ratio of change is equal. For example, we would see a change from 0.1 to 0.2 as being equal to a change from 0.2 to 0.4.

Gamma is a standard constant that is used to calculate the progression. For most screens the gamma constant is in the range of 2.2 to 2.5.

Contrast

Increases or decreases the contrast of the bitmap from -100 to +100 percent.

Histogram Contrast

Increases or decreases the contrast of the image, using a histogram to determine the median brightness.

This method finds the median brightness of the image; then brightens the pixels with values above the median and darkens the pixels with values below the median. This is more sophisticated (but slower) than the Contrast method, which uses the middle possible value (128) rather than finding the actual median.

Possible values: -100 to +100 percent.

Stretch Intensity

Increases the contrast in an image by centering, maximizing, and proportioning the range of intensity values.

Unlike the Contrast method, this method always retains the original number of different intensity values. (Ordinary contrast adjustments can lose values at the high and low ends of the scale.)

Invert

Inverts the colors in the image, making it like a photographic negative.

Hue

Changes the hue of colors in the image by rotating the color wheel.

This method can rotate the color wheel in either direction. A 180-degree rotation in either direction changes each color to its complement. Positive rotation takes red toward green, green toward blue, and blue towards red. Negative rotation has the opposite effect.

Possible values: -180 to +180 degrees.

Saturation

Increases or decreases the saturation of colors in the image.

Negative values decrease the saturation of colors. Set -100 percent to change the colors to grayscale. Positive values increase the saturation. Specify +100 percent to make the colors as bold as they can be.

Histogram Equalize

Linearizes the number of pixels per gray level in the image. This can be used to bring out the detail in dark areas of an image.

Fill Color

Fills the image with the specified color.

You can specify a color by pressing the Change button


Filters
Original Tools: Filters

Halftone

Converts an image to a halftoned image. A halftoned image is a 1-bit bitmap that has been dithered for black and white printing or display.

If the bitmap is originally 1-bit but is not black and white, this method changes it to black and white.

Blur / Sharpen

Increases or decreases the sharpness of the image.

Negative values blur the image. Specify -100 for maximum blur effect. Positive values increase the sharpness. Specify +100 for maximum sharpness.

Posterize

Imposes a poster effect on the image by quantizing the image's colors to a specified number of color levels per plane. For example, two levels means two of red, two of green, and two of blue.

Possible values: 2 to 64 levels.

Mosaic

Imposes a mosaic effect on the image by dividing the bitmap into tiles of a specified size and changing the color of all pixels in each tile to the average color of pixels within the tile.

Possible values: Tile size from 2 to 100 pixels.

Emboss

Applies an emboss effect to the image, letting you specify the depth and direction of the effect.

Soften

Changes the color of each pixel in the bitmap to the average color of pixels in its neighborhood. This results in a blur effect.

You control the amount of blur by specifying the size of the neighborhood that is used for averaging.

Possible values: Neighborhood size from 2 to 100 pixels.

Oil Painting

Applies an oil-painting effect to the image.

You control the effect by specifying the size of the neighborhood that is used for calculating the pixel value. For example, for 8x8, specify 8 for the pixel parameter. Increase the size of the neighborhood in order to decrease the amount of detail in the resulting image.

Possible values: Neighborhood size from 2 to 100 pixels.

Reduce Noise

Changes the color of each pixel in the image to the median color of pixels in its neighborhood for noise reduction.

You control the effect by specifying the size of the neighborhood that is used for calculating the median value. For 8x8, specify 8 for the pixel parameter.

Possible values: Neighborhood size from 2 to 100 pixels.

Add noise

Adds random pixels to the image, letting you specify the percentage of coverage and the color plane.

Possible values: Coverage from 0 to 100 percent, color plane selection.

Intensity detect

Filters the image to detect colors in a specified intensity range.

Intensity levels range from 0 to 255 for each color plane (red, green, and blue). This method processes each plane separately. If a value falls within the range, it is raised to 255, and if it falls outside the range, it is lowered to 0.

Edge detect

Edge detection:

Sobel: Applies Sobel edge detection in the direction specified.

Prewitt: Applies Prewitt edge detection in the direction specified.

Direction

Horizontal or vertical

Line detect

Direction

Horizontal, vertical, left to right or right to left


Special
Original Tools: Special

Rotate

Rotates the image by the specified degrees (0 to +360), and lets you specify the background color to be uncovered. The center of the image is the center of rotation.

Angle

The rotation angle (from -360 to +360). Negativ angles let the image rotate counterclockwise, positiv angles let the image rotate clockwise.

Allow resize of bitmap

Lets you resize the image to accommodate the rotated height and width, or, when unchecked, it retains the original height and width, cropping the bitmap as necessary.

Background Color

Lets you specify the background color to fill any new area created by the rotation.

Parallelogram

Moves the corners of the image in the fashion of a parallelogram.

Moves the corners of the image in the fashion of a parallelogram.

Angle

The angle of slant (from -45 to +45).

Horizontal

Produces horizontal shear.

Vertical

Produces vertical shear.

Background Color

Lets you specify the background color to fill any new area created by the shear.

Flip image

Flips the image from top to bottom or from left to right (mirror).

Flip vertical (mirror)

Flips the image from left to right (mirror).

Flip horizontal

Flips the image from top to bottom.


Variation Image Tools

All image manipulation functions you can assign to a variation image are described here

All image manipulations will immediately be performed when the auto apply option is enabled. Otherwise you have to hit the apply button to perform a change.

Format

Color Resolution


Format
Variation Tools: Format

When the active image is a variation image then you can select between 16 graphics file formats.

GIF

Select this format to save images for internet use. You can choose between the following options:

Interlaced

If you select this option the image will be displayed in more than one step on a web site, with each step showing more details of the image.

Transparency

If selected the image will be saved with one color of the color palette functioning as a transparent color. Click on the Change... button and then on the desired color for transparency in the selected variation. The new transparent color will be displayed on the left side of the Change... button.

GIF Animation

The Animation Frame will only be enabled when you have opened an animated GIF. Initially the animated GIF file will be played continuously in the original image and not be played in the variation image.

Animated

If checked the GIF will be treated as an animated GIF

Image Nr.

You can take an entire look at all frames of an animated GIF when the Play animation button is not pressed. With Image Nr. you can choose the image number of the animated GIF to be displayed in the variation image. This field has no effect when an animated GIF is playing.

Play animation

If pressed the animation will be played continuously (if the opened GIF is an animated GIF with infinite looping).

JPEG

Select this format to save photo realistic images for internet use. You can choose between the following options:

Quality

You can select any setting between 2 (best compression, but worst picture quality) and 254 (bad compression, but superb quality).

Progressive

When checked the image will be saved as a progressive JPEG. Use with caution for internet use, because some web browser don’t support this file format.

No. Passes

When the Progressive checkbox is checked the JPEG file will be saved as a progressive JPEG with this number of passes.

YUV Color

Choose between different colorspace settings. You can choose between YUV 4:4:4 (better quality, but lower compression), 4:2:2 and 4:1:1 (lower quality, but better compression).

Grayscale

When checked the JPEG image will be saved as an 8 bit grayscale JPEG image (= YUV 4:0:0). Use this option for original grayscale images to achieve more compression.

For more supported file formats like PNG, PSD, TIF, compressed TIFF etc. look at Supported Graphics File Formats


Color Resolution
Variation Tools: Color Resolution

For each displayed variation you can change the color resolution, dithering method and color palette:

Pixel Depth

Depending on the selected graphics file format you can choose between different color resolutions. For example, color JPEG files can only be saved in 24 bit color resolution, while the GIF graphics file format allows 1 (2 colors) to 8 bits (256 colors) per pixel color resolution. Changing the color resolution greatly affects the size of an image.

Dithering Method

When the selected pixel depth is at maximum of 8 bits per pixel you can select a dithering method to improve the appearance of an image. You can choose between different dithering methods In general we recommend Floyd Stein dithering method because it seems to produce the best results in most cases.

Colors

When you have selected the optimized palette you can reduce the number of unique colors in an image by setting this field to the desired number of colors. This is a good way to fine tune an image for compression.

Example: You have chosen 3 bits per pixel as the color resolution, that is 2^3 = 8 Colors. If you would set the color resolution to 2 bits per pixel, the maximum number of colors would be 2^2 = 4 Colors. To select 5, 6, or 7 unique Colors for that image you can leave the color resolution at 3 bits per pixel and fill the Colors field with the desired number.

Palettes

Select between 4 predefined color palettes, where Fixed stands for a fixed standard color palette, Optimized for a dynamically generated palette with only adapted colors which are as close as possible to the original colors. The Windows palette contains the system colors filled up with adapted colors (Often similar to Optimized palette). The Netscape palette is a good choice for Web Site images, because most web browsers like Netscape Navigator and MS Internet Explorer are using this palette on screen displays with only 256 colors.

Furthermore you can create and save your own custom palette!


Option Dialog
General Options

You can change the following general settings:

Auto apply variation changes

Indicates whether or not you have to hit the apply button to perform changes you have made to an image variation. This option does not concern changes you make to an image original.

IntelliOptimize GIF/JPEG

The IntelliOptimize feature helps you with choosing the best file format and color and compression settings for your internet images. Based on a variety of decision steps WebGraphics Optimizer chooses the best settings for your file. You can control how WebGraphics Optimizer will make those decisions:

Applies to

You can make different default settings for all variations and for batch processing (Express only). Every time you load a new image WebGraphics Optimizer chooses different settings for all variations you display, depending on the settings you have done.

Choose one of the following file format options:

Always GIF

Indicates that all images will be saved in GIF file format.

Always JPEG

The same as Always GIF, but for JPEG file format.

Depends on color depth

WebGraphics Optimizer will choose GIF when the color depth is less or equal 8 bits / pixel (256 unique colors). Otherwise it will take JPEG for the given variation.

Smallest file size

WebGraphics Optimizer calculates at first the file size of both JPEG and GIF images and then chooses the file format with the smallest file size.

Tip:

All decisions WebGraphics Optimizer makes to choose a file format depend on the GIF and JPEG settings. You can define these settings for each variation and for batch processing (Express only):

GIF settings

Maximum Pixel Depth

WebGraphics Optimizer first checks the number of unique colors in an image. If this results in a higher color depth that specified it cuts the number of colors down. Often this is not noticeable or only a small quality degradation.

Dithering Method

You can choose a dithering method when the number of colors is too low to display good quality. Dithering often results in better image quality, but also in bigger file sizes.

Maximum Colors

When you have chosen the optimized palette then you can limit the number of colors used in an image, regardless of the Maximum Pixel Depth you’ve chosen.

Interlaced GIF

Set this option to true if you want to save interlaced GIF images.

Palettes

Choose the desired color palette for your image. In most cases you will achieve the smallest file size and best image quality with the Optimized color palette.

(see also Color Palette Management System

JPEG settings

Quality

You can select any setting between 2 (best compression, but worst picture quality) and 254 (bad compression, but superb quality).

Progressive

When checked the image will be saved as a progressive JPEG. Use with caution for internet use, because some web browser don’t support this file format.

No. Passes

When the Progressive checkbox is checked the JPEG file will be saved as a progressive JPEG with this number of passes.

YUV Color

Choose between different colorspace settings. You can choose between YUV 4:4:4 (better quality, but lower compression), 4:2:2 and 4:1:1 (lower quality, but better compression).

Grayscale

When checked the JPEG image will be saved as an 8 bit grayscale JPEG image (= YUV 4:0:0). Use this option for original grayscale images to achieve more compression.

Delete original files

The original non optimized image will be deleted after optimization. Use it with care, because it may not your intention to delete your original files!

Overwrite existing files

When checked there will be no security check and message box displaying when overwriting an existing image. Use this option with care! Otherwise you might overwrite your original images with compressed images by accident!

Resize to ... percent

All original images (but NOT those who are marked as “Leave GIF/JPEG unchanged”) will be resized by the given percentage.

Selecting File Lists For Optimization

After you have clicked on “Batch Intelligent Optimization” in the file menu the following dialog appears:

You can select as many files as you want, from as many different directories as you want You can include subdirectories to compress complete folders. You can drag and drop any files and folders from the Windows Explorer into the files window. In case you just want to see how much your files get compressed, click on the “Preview only” button. Then your image files will actually not be saved to disk.

After you have selected all desired images press the “Start Batch Optimization” button. Now you have to choose a destination directory, if you didn’t checked the checkbox ”Save into original directories”.

After choosing a destination directory the batch processing starts:

The Batch Progress Dialog

When you see this dialog the batch optimization process is working. You can stop at any time you want with either the “Stop Processing” button or the escape key. While compression is running you can watch the statistics shown on the progress dialog.


Scanning

You can scan images directly into WebGraphics Optimizer with any Twain compatible scanning device.

1.	Click on “Select Source...” from the “File” Menu to choose the desired Twain compatible device. Your scanner driver must support 32 bit scanning.

1.	Click on “Aquire” to start the scanning process. WebGraphics Optimizer will automatically create a new image window for each of your scanned images. WebGraphics Optimizer supports both single and multipage scanning.

1.	You can now adjust your image with the build in image manipulation tools or select the best compression ratio / file format for internet use (see Optimizing Compression For Internet Use )


Optimizing Compression For Internet Use
Optimizing Image Compression For Internet Use

Here you will find some hints on how to achieve the best compression ratio with WebGraphics Optimizer for your internet graphics files:

There are 3 graphic file formats mainly used for internet images: GIF (standard, interlaced, transparent, animated), JPEG, and the new PNG. Most internet browsers currently support only GIF and JPG images, so we don’t recommend using the PNG graphics file format at this time. Be careful with progressive JPG too, because there are also some browsers that don’t support this file format.

What is the best internet graphics file format for a given image?

That depends on what the characteristics are of that specific file: The LZW compression algorithm used by GIF files is best for images with less colors and wide plain areas with one color. It’s a lossless format, that means you can change and save GIF files without loosing some image information every time you’re saving. The greatest advantage of GIF is that you can choose a transparent color and create animated sequences. If you want to use these features you can only choose GIF as your internet graphics file format.

GIF files support up to 256 colors, so it’s not the best choice for photo realistic images. For that kind of images you should use JPEG file format. It produces much smaller images and always saves an image in 24 bit (for color images) or 8 bit (for grayscale images). With JPEG, there are some less or more obvious flickers and hisses visible, depending on the compression ratio you’ve selected. WebGraphics Optimizer assists you perfect in choosing the best compromise in image quality and file size.

If you are not sure which graphics file format to choose, GIF or JPEG, then we suggest you to open two variations, one with GIF and one with JPEG. Then you can play with the color and compression settings to find out which format to choose.


Selecting Regions
Regions

What is a region?

A region is any combination of rectangle, ellipse, rounded rectangle and freehand selection of an image. All image manipulations can be limited to a region.

How can I create a region?

Just click at the upper left corner to define the beginning of the region and then move the mouse while the left mouse button is hold down.

To add a new area to a region, just press the shift key and start a new selection as described above. To remove parts of an already selected area, press the control key and start a new selection.

To change the shape of a region select Edit / Select Region from the menu bar.

What can I do with a region?

- A region limits all image manipulations to the specified region.

- Move the mouse while holding down the left mouse button moves the content of the region.

- Pressing the left mouse button outside the region makes the changes permanent.

- Pressing the Delete key fills the region of an image with white color.

- Pressing the Escape key removes the region without making the changes permanent.


Supported Graphics File Formats

Internet File Formats:

JPEG (Joint Photographic Experts Group)

This format is commonly used to display photographs and other continuous-tone images on World Wide Web sites. Unlike the GIF format, JPEG retains all the color information in an RGB image. JPEG also uses a compression scheme that effectively reduces file size by identifying and discarding extra data not essential to the display of the image. The JPEG compression scheme is a lossy compression. This means that once an image has been compressed and then decompressed, it will not be identical to the original image. A higher level of compression results in lower image quality, while a lower level of compression results in better image quality. In most cases, compressing an image using the Maximum quality option produces a result that is indistinguishable from the original.

Progressive JPEG

This is a JPEG format that is useful for transmitting images, because the first part of the file contains the full dimensions of the image. Therefore, the whole image is displayed and then progressively clarified as the rest of the file loads.

Image Options	Read	Write
Bits Per Pixel	8, 24	8, 24
YUV Color Spacing	4:4:4, 4:2:2, 4:1:1 and grayscale	4:4:4, 4:2:2, 4:1:1 and grayscale
Progressive JPEG	yes	yes
Image Quality	-	2 (lowest) -256 (highest)

GIF (Compuserve Graphics Interchange Format)

GIF is the file format commonly used to display indexed-color graphics and images in World Wide Web sites. GIF is a compressed format that is designed to minimize file transfer time over phone lines.

When saving an image as GIF, you can specify how the image appears as it is downloaded. Select Interlaced to display the image gradually in increasing detail as it is downloaded.

Select a transparent color in the image and save it.

Image Options	Read	Write

Interlaced	yes	yes
Transparent	yes	yes
Animated	yes	yes

PNG (Portable Network Graphics)

PNG is a replacement for the GIF format. It is a full-featured (non-LZW) compressed format intended for widespread use without legal restraints. It is a lossless format like GIF but usually with better compression and no limitation to 256 colors.

Image Options	Read	Write
Bits Per Pixel	1, 4, 8, 16, 24, 32	1, 4, 8, 24

Other Color Graphics Formats:

BMP

BMP is the standard Windows bitmap image format on DOS and Windows-compatible computers. When saving an image in this format, you can specify either Microsoft Windows or OS/2 format and a 1-bit to 24-bit depth for the image. For 4-bit and 8-bit images, you can also choose to use Run-Length-Encoding (RLE) compression; this compression scheme is lossless, that is, it does not discard detail from the image.

Image Options	Read	Write
Bits Per Pixel In Windows Format	1, 4, 8, 16, 24, 32	1, 4, 8, 16, 24, 32

EPS (Encapsulated PostScript)

These files are used primarily on PostScript printers. These printers usually offer more variety of fonts and higher resolution than standard laser printers. EPS files will work on any PostScript compatible printer and any end-user application that supports placement of EPS files in its work space.

The image that you read from an EPS file can be either a PostScript raster image or an embedded TIFF image. The image that you write to an EPS file is always a PostScript raster image.
