Use Background - Sets an image that will be used as a background when converting a .txt file to PDF

Image to PDF

These settings apply to Converting Images to PDF or Importing Images as Pages.

Color Images - Settings used when color images are converted

Compression - Convert any image to either a JPEG, JPEG2000, FLATE, or JBIG2.

JPEG: lossy compression that will reduce image quality and size
JPEG2000: less lossy compression that will reduce size and some quality
FLATE: Lossless compression does not reduce quality
JBIG2: Lossless compression that can only support black and white colors. Color images will be converted to black and white. Best for scanned documents with no images

Note: Anytime a change is made to “Color Space” or “DPI” the image will have to be re-compressed. When the “No Change” option is selected, PDF Studio will attempt to keep the current image compression format. If it is not supported, PDF Studio will re-compress to the closest matching supported compression.

JPEG Quality - Allows the image quality to be adjusted between 10-100%.

This will only affect JPEG or JPEG2000 images as these are the only formats that support image quality settings.

Color Space - Choose to either retain or convert the image colors to Grayscale or B&W.

Gray: Only supported with JPEG, JPEG2000, or FLATE. Best for full color images
B&W: Only supported by FLATE or JBIG2. Best for scanned documents with no images

Note: When the “No Change” option is selected, PDF Studio will attempt to keep the current image color space. If it is not supported, PDF Studio will change to the closest matching supported color space. JPEG images with CMYK color space will be converted to RGB due to a regression bug in JDK 1.7.

Grayscale Images - Settings used when grayscale images are converted

Compression - Convert any image to either a JPEG, JPEG2000, FLATE, or JBIG2.

JPEG: lossy compression that will reduce image quality and size
JPEG2000: less lossy compression that will reduce size and some quality
FLATE: Lossless compression does not reduce quality
JBIG2: Lossless compression that can only support black and white colors. Color images will be converted to black and white. Best for scanned documents with no images

JPEG Quality - Allows the image quality to be adjusted between 10-100%.

This will only affect JPEG or JPEG2000 images as these are the only formats that support image quality settings.

Color Space - Choose to either retain or convert the image colors B&W.

B&W: Only supported by FLATE or JBIG2. Best for scanned documents with no images

Black and White Images - Settings used when black and white images are converted

Compression - Convert any image to either a FLATE or JBIG2.

FLATE: Lossless compression does not reduce quality
JBIG2: Lossless compression that can only support black and white colors. Color images will be converted to black and white. Best for scanned documents with no images

Optimize images only if there is a reduction in size - when checked image conversion will validate that the new image using the selected options is actually smaller in bytes than the original. If not the original image will remain in the newly created document.
