net.sf.jasperreports.allow.element.negative.width
	A property that determines whether elements having negative width values are allowed. If this value is set to `false`, the report is verified not to contain elements with negative width values. This is useful when the report is meant to be exported to grid-based formats such as HTML, XLS or CSV, which might enter an infinite loop. Having elements with negative widths does not make sense, but allowing this is a workaround in case older report templates still need to pass validation at report compile time.

	API	PROPERTY_ALLOW_ELEMENT_NEGATIVE_WIDTH
	Default	false
	Scope	Global \| Report
	Since	3.7.1
top

net.sf.jasperreports.allow.element.negative.y
	Property that determines whether elements positioned at negative Y offsets on bands, frames and other element containers are allowed in a report. Elements placed at negative Y offsets can cause unexpected problems in grid-based exporters where they can overlap elements from previous bands/element containers. If the property is set to `false`, elements in the report are verified to have positive Y offsets. Otherwise, no check is performed on element Y offsets.

	API	PROPERTY_ALLOW_ELEMENT_NEGATIVE_Y
	Default	true
	Scope	Global \| Report \| Element
	Since	3.7.3
top

net.sf.jasperreports.allow.element.overlap
	A property that determines whether elements are allowed to overlap. If this value is set to `false`, the report is verified not to contain elements that overlap. This is useful when the report is meant to be exported to grid-based formats such as HTML, XLS or CSV. Setting this property to `false` ensures that element overlap issues are caught at report compile time. Additionally, when this property is set to false `false`, the report is verified not to have any content in the background section as this content would likely be overlapped by other sections and would not show in grid-based exporters. By default, the property is set to `true` which means that no element overlap checks are performed. The property can be set at the following levels: At global level (in jasperreports.properties) to provide a default value. At report level, to indicate whether element overlap checks are to be performed for the report. If not set, the global property value is used. At report element level to specify that the particular element is allowed to overlap or be overlapped by other elements, when the report or global property determines report element overlap verification. The element level property is only effective when set to `true`; setting the property to `false` does not make the verifier check for overlaps when the report is not set to be checked for element overlaps. Note that print when expressions or export filters cannot be taken into consideration while checking for overlapping elements as this check is performed at report compilation time. If a report contains two elements that overlap but have print when expressions that guarantee that only one of them will be printed, or if export filters are in place to exclude one of the elements, one of them should be explicitly marked to allow element overlap when the report is configured to check for overlaps.

	API	PROPERTY_ALLOW_ELEMENT_OVERLAP

top

net.sf.jasperreports.awt.check.available.printers

net.sf.jasperreports.awt.ignore.missing.font

These properties should start with the `net.sf.jasperreports.export.xls.sheet.names.` prefix, and should end with an arbitrary suffix. Any of them can hold one or many sheet names, separated by the slash ("/") separator. Values are collected in the same order as they are enumerated in the jrxml template, so one have to be careful with that order when editing a jrxml. The ending suffix is not important, but the order is very. For instance, if a given report has 3 resulting sheets, there are multiple possibilities to define the sheet names within the jrxml template: To have a single property for each sheet name: `<property name="net.sf.jasperreports.export.xls.sheet.names.sheet1" value="First sheet" /> <property name="net.sf.jasperreports.export.xls.sheet.names.second.sheet.name" value="Second sheet" /> <property name="net.sf.jasperreports.export.xls.sheet.names.3" value="Third sheet" />` Then, the 3 resulting sheets will be named as follows: First sheet Second sheet Third sheet To have a single property containing all sheet names, separated by the "/" separator: `<property name="net.sf.jasperreports.export.xls.sheet.names.all" value="First sheet/Second sheet/Third sheet" />` Then, the 3 resulting sheets will be named as follows: First sheet Second sheet Third sheet The order is very important, as shown above. To have any combination of 1) and 2): `<property name="net.sf.jasperreports.export.xls.sheet.names.first" value="First sheet" /> <property name="net.sf.jasperreports.export.xls.sheet.names.others" value="Second sheet/Third sheet" />` Then, the 3 resulting sheets will be named as follows: First sheet Second sheet Third sheet Finally, if the user sets less sheet names (let's say x) than the number of sheets, the exporter will use the custom user sheet names for the first x sheets in the document, and the remaining sheets will be named by default as "Page y", where y is the current page number. These properties are by default not set.

This applies to report elements that can have delayed evaluations times (such as text fields and images). When this flag is set to `true`, conditional style expressions of the style that is associated with the element are evaluated at the moment the element is set to evaluate, and the resulting style to the generated print element.

top

net.sf.jasperreports.text.measurer.factory
	This property can either hold the name of a text measurer factory class, or hold an alias of a text measurer factory class property. One can write an implementation of the JRTextMeasurerFactory interface. This will usually imply writing a custom implementation of the JRTextMeasurer interface, either from scratch or by extending the default implementation (TextMeasurer). A text measurer is responsible with computing text layout attributes (in the form of JRMeasuredText instances) for report text elements. The measurer is only used at report fill time, the exporters will use the computed text layout attributes. Then one can define an alias of the text measurer factory implementation by declaring a property `named net.sf.jasperreports.text.measurer.factory.{alias}` which has the name of the factory class as value. The `net.sf.jasperreports.text.measurer.factory` property is set to a defined alias or a full factory class name. The factory class is used to instantiate text measurers for report text elements, which are then used to compute the text layout attributes.

net.sf.jasperreports.text.save.line.breaks
	Boolean property that determines whether the positions where text line break occurs are to be saved during report fill in oder to be used at export time. At report fill time, each text element is measured in order to determine how long it needs to stretch or where it needs to be truncated. During this measurement, the text wraps at certain positions in order to fit the text element defined width. Setting this property to true instructs the engine to save the positions at which line breaks occur in the generated print element. The positions can be used by report exporters that want to enforce line breaks to occur at exactly the same position as they did during text measurement at fill time. Currently, the HTML exporter will make use of the saved line break positions by introducing explicit line breaks.

	Default	false
	Scope	Global \| Report \| Text Element
	Since	3.5.1

net.sf.jasperreports.text.truncate.at.char

net.sf.jasperreports.text.truncate.suffix
	Property whose value is used as a suffix for the truncated text. The suffix is appended to the text when truncation occurs. If the property is not defined or empty (which is the case by default), no suffix will be used when the text is truncated.

	Since	2.0.3
top

net.sf.jasperreports.viewer.render.buffer.max.size
	Maximum size (in pixels) of a buffered image that would be used by JRViewer to render a report page. If rendering a report page would require an image larger than this threshold (i.e. image width x image height > maximum size), the report page will be rendered directly on the viewer component. If this property is zero or negative, buffered images will never be used to render a report page.

net.sf.jasperreports.virtualizer.files.delete.on.exit
