Although JPEG was originally intended for use in Internet-based applications, it is becoming an ever more popular file format for high-end word processing applications. A JPEG file is encoded by using an adjustable lossy compression approach. This means that to achieve smaller file sizes, image data is actually removed from the image file.
In small doses, the JPEG compression approach can be very effective and efficient. However, in larger amounts, the resulting file will contain noise and undesired artifacts in the image.
JPEG export was originally introduced in TX Text Control ActiveX 9.0 and quickly established itself as a popular feature.
TX Text Control 11.0 now supports the setting of:
- JPEG Compression Quality
- JPEG Image Resolution
JPEG Compression Quality
TX Text Control 11.0 allows the compression dosage to be set from program code. The greater the amount of JPEG compression applied, the smaller the file size of the image will become. However, this reduction of file size comes at the price of deterioration of image quality.
Sample Images
Consider the following examples:
The image to the left has been saved as a JPEG file, setting the compression at the minimum level. The result is an almost perfect image; however, the file size is a hefty 495 kB. The image to the right has been saved as a JPEG file, setting the compression at the maximum level. The result is a very lossy image; however, the file size is a mere 68 kB.
TX Text Control 11.0 allows images to be exported to JPEG files, setting the compression to any value on the range of 0 to 100.
JPEG Image Resolution
If there are more than 300 dots per square inch, humans cannot detect those dots that are in excess of this threshold. For clear and crisp printing, images at their final size in the layout should be at 300 DPI (400 DPI, if the images include text). It therefore makes sense to take care of all DPI parameterization when a word processing document is saved. Using TX Text Control 11.0, this is possible directly from program code.
Sample Images
Consider the following examples:

| Image crisp @ 300 DPIs | Image fuzzy @ 72 DPIs |
