Important: Parameters marked with an asterisk (*) are required and must be provided for the API to function correctly.

Required Parameters​

ParameterTypeDescriptionExample
docName*StringThe source image filename with proper file extension for image resizing operations. This parameter identifies the input image for resizing processing, dimension control, and optimization workflows. Required for image identification and processing pipeline management in image resizing operations.stamp.jpg
docContent*Base64The complete content of the source image encoded in Base64 format for image resizing processing. This parameter contains the entire image data required for resizing, dimension control, and optimization workflows. Essential for secure image handling and API-based image resizing operations.JVBERi...
Image Resize Type*StringSelect the resizing method for image processing operations. Choose from Percentage for proportional scaling or Specific for exact dimension control. This parameter determines the resizing strategy and ensures proper image scaling for different optimization requirements.Percentage
Resize Percentage*DecimalSpecify the resizing percentage as a decimal value for proportional image scaling. This parameter controls the scaling factor for percentage-based resizing operations. Use decimal values like "20.1010" for precise percentage control and proportional image scaling in resizing workflows.20.1010
Width*IntegerSpecify the target width in pixels for specific dimension resizing operations. This parameter controls the horizontal dimension of the resized image. Use integer values for precise width control and optimal image sizing in specific dimension resizing workflows.60
Height*IntegerSpecify the target height in pixels for specific dimension resizing operations. This parameter controls the vertical dimension of the resized image. Use integer values for precise height control and optimal image sizing in specific dimension resizing workflows.60
Maintain Aspect Ratio*BooleanControl whether to preserve the original image aspect ratio during resizing operations. Set to 'true' to maintain proportional scaling, or 'false' to allow non-proportional resizing. This parameter ensures proper image proportions and prevents distortion during resizing operations.true
