174 4600 Series IP Telephones Application Programmer Interface (API) Guide
The Image Area is the screen area that is available for the browser to render that particular
image. If an image overflows the image area, the graphic engine expands to the right and
downward until the image completes or truncates the image at the image area’s border (screen
glass). The hspace and vspace values define the Image Area.
Images line up with the left side Feature buttons as follows:
● A 0 (zero) pixel border on the left and right sides of all images displayed, as well as on top
of any image displayed. The border area is empty.
● A 0 (zero) pixel border at the bottom.
● No 0 (zero) pixel border on the top of the remaining lines of images that span multiple
lines.
Left-justified images begin at pixel 0. Center-justified images center at pixel 146. Right-justified
images end at pixel 291.
The default values for hspace and vspace are 0 pixel. This default value is honored only if the
authors have not specified their own hspace and vspace values.
Image Size
The maximum width of an image is 291 pixels. The maximum height is 30 pixels of height x 96
lines is 2880 pixels. Images greater than 291 X 1536 pixels are truncated. This is translated as
the maximum image width being from pixel 1 to pixel 291. The maximum height is 96 lines.
Images greater than the maximums are truncated.
Each Call Appearance/Application Area is 29 pixels in height, including one black pixel at the
bottom of the area, making the maximum supported image height 96 lines x 30 pixels, or 2880
pixels.
To ensure the best image quality, use only images having an equal height and width. Odd width
and/or height images will automatically be adjusted to even-sized images. For example, the
right and/or bottom 1-pixel edge(s) will be removed.
JPEG images can appear in the softkey area. The softkey label area is 30 pixels in height,
including one black pixel at the top of the area extending across the width of the display. Each
softkey can be a maximum of 79 pixels in width and 29 pixels high.
Scaling to reduce images to fit the screen is not supported. This means that if an image is
bigger than the screen width/height, both the width and the height of the image will be truncated.
WML is intended for small screens. Large images are not recommended.
Softkey # Pixel Range
1 0 - 79
2 80 - 159
3 160 - 239
4 240 - 319
