Question

如何把小图转成大图且保持图像的清晰？

Answer 1

用高精度相机或扫描仪扫出来后，对着图像进行描画，这得有一定的绘画水平才行。

将大图转小很容易保持图像的清晰度，小图转大，难！

Answer 2

要想放大图片还要保持清晰只能对图片进行插值，这样的软件有不少，photoshop可以

1、打开软件。
/iknow-pic.cdn.bcebos.com/0bd162d9f2d3572cc167e0368413632763d0c357"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/0bd162d9f2d3572cc167e0368413632763d0c357?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/0bd162d9f2d3572cc167e0368413632763d0c357"/>
2、打开图片。
/iknow-pic.cdn.bcebos.com/ae51f3deb48f8c54af84bac534292df5e1fe7f80"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/ae51f3deb48f8c54af84bac534292df5e1fe7f80?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/ae51f3deb48f8c54af84bac534292df5e1fe7f80"/>
3、放大图片。可以直接调整选择需要的尺寸。
/iknow-pic.cdn.bcebos.com/86d6277f9e2f0708e98356eae724b899a801f252"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/86d6277f9e2f0708e98356eae724b899a801f252?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/86d6277f9e2f0708e98356eae724b899a801f252"/>
4、或者直接输入放大的比例（如放大一倍）。
/iknow-pic.cdn.bcebos.com/eaf81a4c510fd9f921a32a832b2dd42a2934a4a0"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/eaf81a4c510fd9f921a32a832b2dd42a2934a4a0?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/eaf81a4c510fd9f921a32a832b2dd42a2934a4a0"/>
5、右侧的图片会自动放大一倍，且会根据默认的调整大小的方式自动处理不清晰的图片，使之尽可能清晰。
/iknow-pic.cdn.bcebos.com/562c11dfa9ec8a13b10b280af903918fa1ecc0c3"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/562c11dfa9ec8a13b10b280af903918fa1ecc0c3?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/562c11dfa9ec8a13b10b280af903918fa1ecc0c3"/>
6、处理好之后，“保存”。
/iknow-pic.cdn.bcebos.com/63d9f2d3572c11df7961c0c96d2762d0f603c2ac"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/63d9f2d3572c11df7961c0c96d2762d0f603c2ac?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/63d9f2d3572c11df7961c0c96d2762d0f603c2ac"/>
7、放大一倍后的图片，效果如下。
