This documentation provides a guide on how to set barcode sizes using in the Aspose.BarCode Cloud SDK for Java. This guide includes examples and descriptions for configuring the height, width, and resolution of barcode images.
The GenerateApi
interface offers several methods for generating barcodes through different types of HTTP requests:
To control the size of a barcode, the following properties in the request objects can be configured:
imageHeight
: Specifies the height of the barcode image.imageWidth
: Specifies the width of the barcode image.resolution
: Defines the resolution (DPI) of the barcode image.units
: Defines the measurement units (e.g., pixel, inch, millimeter).import com.aspose.barcode.cloud.ApiClient;
