Hi,
When using an image generated in JFreeChart which appears crisp in web
browser, same image appears blurry when
embedded as Picture within HSLF slideshow. Here are some details:
image generated by standard chart factory and saved as:
new BufferedImage(width, height, BufferedImage.TYPE_INT_RBG)
image is then read in by:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] bytesOut = null;
int picNdx = -1;
try {
ImageIO.write(img, imgType, baos);
bytesOut = baos.toByteArray();
baos.close();
picNdx = ppt.addPicture(bytesOut, Picture.PNG);
} catch (IOException e) {
.
.
Where imgType = "png"
the dimensions for the anchor are the same as the images dimensions
specified by the JFreeChart method.
The image always looks blurry. I suspect the default size of the Picture to
have something to do with this
in regards to the POINT_DPI/PIXEL_DPI yet I never invoke the
Picture.setDefaultSize() method.
Any suggestions as to how to enhance the crispness of the embedded image?
Thanks,
Henry
