| Memory Management |
org.icepdf.core.minMemory
|
string |
Sets the amount of Java heap memory to reserve as a safety buffer to prevent OutOfMemory Exceptions from occurring. If the amount of used Java heap memory is greater than (Max Memory - org.icepdf.core.minMemory), the memory manager will flush pages in the page cache until the required amount of Java heap memory is available. The default is 5MB. |
No |
org.icepdf.core.maxSize
|
integer |
Specifies the maximum number of pages that should be cached at one time. The default is 0, which results in as many pages as will fit in the available memory being cached. A value of 1 effectively disables the page cache. |
No |
org.icepdf.core.purgeSize
|
integer |
Sets the number of pages that are purged from the page cache each time the memory manager attempts to free memory. Default value is 5 pages. |
No |
| Caching |
org.icepdf.core.imagecache.enabled
|
boolean |
If true, images are cached to the hard drive. The default value is true. |
No |
| Rendering Quality Note: For the following group of properties, target can be set for both print and screen. For dynamic changes to these System Properties to take effect, you must call org.icepdf.core.util.GraphicsRenderingHints.reset(). |
org.icepdf.core.awtFontLoading
|
boolean |
When enabled the java.awt.Font will be used to try and load embedded font files. Default value is false. Has no effect on ICEpdf Pro. |
No |
org.icepdf.core.scaleImages
|
boolean |
Scales images with a pixel width greater than 1000 to improve memory usage and image clarity. Default value is true. |
No |
org.icepdf.core.target.
alphaInterpolation
|
string |
Sets the JVM's alpha interpolation rendering hint. The default value for print is VALUE_INTERPOLATION_QUALITY. The default value for screen is VALUE_INTERPOLATION_QUALITY. The other supported value is VALUE_ALPHA_INTERPOLATION_
DEFAULT |
Yes |
org.icepdf.core.target.
antiAliasing
|
string |
Sets the JVM's antialiasing of all images and text. The default value for print and screen is VALUE_ANTIALIAS_ON. Other supported values are VALUE_ANTIALIAS_DEFAULT and VALUE_ANTIALIAS_OFF. |
Yes |
org.icepdf.core.target.background
|
string |
Sets whether a Page will draw a background fill color before drawing the Page contents. According to the PDF standard, a white background should be drawn. When printing on white paper, for some printers with poor drivers, it is best to not draw a background at all. The default value is VALUE_DRAW_WHITE_BACKGROUND. The other supported value is VALUE_DRAW_NO_BACKGROUND. |
Yes |
org.icepdf.core.target.colorRender
|
string |
Sets the JVM's color render rendering hint. The default value for print and screen is VALUE_COLOR_RENDER_QUALITY. The other supported values are VALUE_COLOR_RENDER_DEFAULT. |
Yes |
org.icepdf.core.target.dither
|
string |
Sets the JVM's dither rendering hint. The default value for print and screen is VALUE_DITHER_ENABLE. Other supported values are VALUE_DITHER_DEFAULT and VALUE_DITHER_DISABLE. |
Yes |
org.icepdf.core.target.
fractionalmetrics
|
string |
Sets the JVM's fractional metrics rendering hint. The default value for print and screen is VALUE_FRACTIONALMETRICS_ON. Other supported values are VALUE_FRACTIONALMETRICS_DEFAULT and VALUE_FRACTIONALMETRICS_OFF. |
Yes |
org.icepdf.core.target.
interpolation
|
string |
Sets the JVM's interpolation rendering hint. The default value for print and screen is VALUE_INTERPOLATION_BICUBIC. The other supported values are VALUE_INTERPOLATION_BILINEAR and VALUE_INTERPOLATION_NEAREST_
NEIGHBOR. |
Yes |

textAntiAliasing
|
string |
Sets the Font rendering engine's antialiasing rendering hint. The default value is true. The other supported value is false. |
Yes |
org.icepdf.core.scaleImages
|
boolean |
If true, large images are scaled dynamically to a reduced resolution appropriate for online display or printing. The dynamic scaling does its best to preserve image quality and minimize memory requirements. The default value is true. |
No |

org.icepdf.core.views.buffersize.
vertical
|
string |
Sets the vertical ratio that the current viewport height will be multiplied by to create a screen buffer. The default value is 1.0. Using a larger ratio will increase the amount of memory needed by the page view. |

horizontal
|
string |
Sets the horizontal ratio that the current viewport width will be multiplied by to create a screen buffer. The default value is 1.0. Using a larger ratio will increase the amount of memory needed by the page view. |
