Hi
I use Aspose PDF 17.5 to save a PDF file into HTML format.
I found that some of images turned gray instead origin color in the result
Please check this issue, and the attachment.
P.S. my testing code:
public void asposeConvert() throws Exception {
String fileName = “testPDF2.pdf”;
Document pdf = new Document(“input/”+fileName);
HtmlSaveOptions htmlSaveOps = new HtmlSaveOptions();
htmlSaveOps.RasterImagesSavingMode = HtmlSaveOptions.RasterImagesSavingModes.AsEmbeddedPartsOfPngPageBackground;
htmlSaveOps.FontSavingMode = HtmlSaveOptions.FontSavingModes.AlwaysSaveAsWOFF;
htmlSaveOps.PartsEmbeddingMode = HtmlSaveOptions.PartsEmbeddingModes.EmbedAllIntoHtml;
htmlSaveOps.LettersPositioningMethod = LettersPositioningMethods.UseEmUnitsAndCompensationOfRoundingErrorsInCss;
htmlSaveOps.setSplitIntoPages(false);
File f = new File(fileName + “/”);
f.mkdirs();
for (int p = 1; p <= pdf.getPages().size(); p++) {
Document pageDoc = new Document();
pageDoc.getPages().add(pdf.getPages().get_Item§);
final ByteArrayOutputStream stream = new ByteArrayOutputStream();
htmlSaveOps.CustomHtmlSavingStrategy = new HtmlSaveOptions.HtmlPageMarkupSavingStrategy() {
@Override
public void invoke(com.aspose.pdf.HtmlSaveOptions.HtmlPageMarkupSavingInfo htmlSavingInfo) {
try {
byte[] resultHtmlAsBytes = IOUtils.toByteArray(htmlSavingInfo.ContentStream);
htmlSavingInfo.ContentStream.read(resultHtmlAsBytes, 0, resultHtmlAsBytes.length);
stream.write(resultHtmlAsBytes);
stream.close();
} catch (FileNotFoundException e) {
} catch (IOException e) {
} finally {
IOUtils.closeQuietly(htmlSavingInfo.ContentStream);
}
}
};
String outHtmlFile = “SomeUnexistingFile.html”;
pageDoc.save(outHtmlFile, htmlSaveOps);
IOUtils.write(stream.toByteArray(),
new FileOutputStream(fileName + “/” + p + “.html”));
}
}
