Types ¶
type ContentStreamInlineImage ¶
type ContentStreamInlineImage struct {
BitsPerComponent core.PdfObject
ColorSpace core.PdfObject
Decode core.PdfObject
DecodeParms core.PdfObject
Filter core.PdfObject
Height core.PdfObject
ImageMask core.PdfObject
Intent core.PdfObject
Interpolate core.PdfObject
Width core.PdfObject
// contains filtered or unexported fields
}
A representation of an inline image in a Content stream. Everything between the BI and EI operands. ContentStreamInlineImage implements the core.PdfObject interface although strictly it is not a PDF object.
func (*ContentStreamInlineImage) DefaultWriteString ¶
func (this *ContentStreamInlineImage) DefaultWriteString() string
func (*ContentStreamInlineImage) String ¶
func (this *ContentStreamInlineImage) String() string
type ContentStreamOperation ¶
type ContentStreamOperation struct {
Params []PdfObject
Operand string
}
type ContentStreamOperations ¶
type ContentStreamOperations []*ContentStreamOperation
func (*ContentStreamOperations) Bytes ¶
func (this *ContentStreamOperations) Bytes() []byte
Convert a set of content stream operations to a content stream byte presentation, i.e. the kind that can be stored as a PDF stream or string format.
func (*ContentStreamOperations) WrapIfNeeded ¶
func (this *ContentStreamOperations) WrapIfNeeded() *ContentStreamOperations
Wrap entire contents within q ... Q. If unbalanced, then adds extra Qs at the end. Only does if needed. Ensures that when adding new content, one start with all states in the default condition.
type ContentStreamParser ¶
type ContentStreamParser struct {
// contains filtered or unexported fields
}
Content stream parser.
func NewContentStreamParser ¶
func NewContentStreamParser(contentStr string) *ContentStreamParser
Create a new instance of the content stream parser from an input content stream string.
func (*ContentStreamParser) Parse ¶
func (this *ContentStreamParser) Parse() (*ContentStreamOperations, error)
Parses all commands in content stream, returning a list of operation data.
func (*ContentStreamParser) ParseInlineImage ¶
func (this *ContentStreamParser) ParseInlineImage() (*ContentStreamInlineImage, error)
Parse an inline image from a content stream, both read its properties and binary data. When called, "BI" has already been read from the stream. This function finishes reading through "EI" and then returns the ContentStreamInlineImage.
type ContentStreamProcessor ¶
type ContentStreamProcessor struct {
// contains filtered or unexported fields
}
func NewContentStreamProcessor ¶
func NewContentStreamProcessor(ops []*ContentStreamOperation) *ContentStreamProcessor
func (*ContentStreamProcessor) AddHandler ¶
func (csp *ContentStreamProcessor) AddHandler(condition HandlerConditionEnum, operand string, handler HandlerFunc)
func (*ContentStreamProcessor) Process ¶
func (this *ContentStreamProcessor) Process(resources FontsByNames) error
Process the entire operations.
type HandlerConditionEnum ¶
type HandlerConditionEnum int
const ( HandlerConditionEnumOperand HandlerConditionEnum = iota HandlerConditionEnumAllOperands HandlerConditionEnum = iota )
func (HandlerConditionEnum) All ¶
func (this HandlerConditionEnum) All() bool
func (HandlerConditionEnum) Operand ¶
func (this HandlerConditionEnum) Operand() bool
type HandlerEntry ¶
type HandlerEntry struct {
Condition HandlerConditionEnum
Operand string
Handler HandlerFunc
}
type HandlerFunc ¶
type HandlerFunc func(op *ContentStreamOperation, resources FontsByNames) error
type HandlerFunc func(op *ContentStreamOperation, gs GraphicsState, resources *PdfPageResources) error
